Abstract: This paper discusses the use of theatrical techniques in two experiments to attain the following objectives of

interaction design: to communicate the cross-cultural users’ needs and expectations for iDTV (interactive

Digital TeleVision) services and to explore new ideas in a participatory way. These two objectives are

particularly important when systems are involved that are unknown to people, and professionals need to

gather the requirements of such systems. In the first experiment, we showed the implication of stories told

through theater in order to communicate the purposes of iDTV services to the audience. In the second

experiment, we used role-playing in participatory interaction design sessions to explore new ideas with

users. The results are described by discussing the strengths and weaknesses of this approach.

1 INTRODUCTION

Electronic devices and interactive systems have

evolved in a very fast way. This trend has brought

difficulties for professionals responsible for the

development of these technologies to understand

what people really need. The basic question is:

professionals address users´ actual needs or they are

just creating imaginary needs for people? Several

techniques entail understanding these needs of a

particular user group (a targeted user group).

However this practice may not bring relevant

outcomes if target users have little familiarity with

the innovative technology. This situation leads to a

need to engage targeted users in simulated situations

to explore their ideas, attitude and emotions.

Professionals should also focus on human needs and

usage patterns to identify how current technologies

are used and appropriated. These both attitudes can

lead them to identify or predict needs that will

emerge together with available technologies and

emerging trends.

By focusing on our attention to understand and

communication what people need in terms of

interactive Digital TV services (iDTV), we find

ways to share information between targeted users

and designers and among professionals.

This paper proposes the use of theater to

understand the context of users and to explore their

ideas when they are taking different roles in situ in

participatory design sessions. Users will be

motivated to assist designers in the project of

interaction of a product, being not only a source of

information (saying what their expectations are, for

instance), but also providing ideas to build solutions

that are more appropriate to their needs. In addition,

theater is also used to help designers both to

communicate interaction design solutions and to

evaluate the proposed design with stakeholders

(members of the team, those responsible for the

deployment of the iDTV services, and target users of

these services).

The article is divided into six sections, described

as follows: the second section presents an HCI study

that discusses interaction design techniques; the

third section illustrates several research questions

that will be investigated during this work; sections 4

and 5 show the experiments conducted in order to

explore the formulated questions; the sixth section

presents the results of the experiments; lastly, the

seventh section presents the final considerations of

this work before the conclusion.

2 THEATER IN THE

INTERACTION DESIGN

Exploring new ideas when having to design new

solutions is a challenge. This is the case of

sophisticated technological systems in which the

domains (such as digital TV, smart home, and

tangible interfaces) represent a new paradigm of

interactivity. One of the reasons is that users often

have difficulties in formulating their needs because

they lack knowledge about the potential usages of

the innovative technology. Designers must apply

techniques that enable users to imagine living with

the technology. The prototyping technique (such as

Wizard of Oz (Dahlback et al., 1993) (Molin, 2004))

partially supports this imaginary process, because it

is possible to represent some characteristics of

design and simulate some functionalities before

having the final product.

However, the prototyping technique is often

applied to validate design alternative solutions

having an exclusive focus on user interfaces

(sequence and position of information) (Tohidi et al.,

2006).

Professionals have also been applying

prototyping techniques by matching scenarios

(Carroll, 2000) and storyboards that illustrate, in a

low-fidelity way, the possibilities of interaction

narrated in the scenarios (Dow et al. 2006). In the

scenarios, these possibilities have been described in

function of the persona notion (Cooper, 2003),

which allows the description of the daily patterns of

user behaviors concerning a service and/or product.

Scenarios have become a widely-accepted practice

to describe the users’ experience living with the

technology (McCarthy and Wright, 2004). However

there are some situations in which these practices do

not capture all the nuances of the interaction. This is

the case when the users’ emotional reactions depend

on the social environment and cultural context in

which the interaction takes place.

Taking this approach of Experience Prototyping

(Buchenau & Suri, 2000) into account is aimed at

making it easier for designers to better evaluate the

integration of the technology in the real context of

use in a dynamic and holistic way, using (for

instance) role-playing in experience prototyping

design sessions.

The theater is a way representing the real world

and, through this representation, the individual

reacts, and experiments her/his own emotions,

among other feelings. Howard and his colleagues

(2002) have used theater to explore the interrelations

between technology and situations of use. In

(Newell et al., 2006), the technique of theater was

used to transmit important messages about

characteristics of older people. Afterwards, a video

was recorded and shown in a focus group session to

encourage audience (future-user) participation. We

wish to use both the enactments and a recorded

video as complementary artifacts to scenarios and

storyboards. We believe that when scenarios of an

interaction design are acted out by users in their own

physical and social-cultural environment, they

become very involved by pretending they are

actually using the technology. Their reactions help

professionals to reflect on the implications for

design.

3 RESEARCH ASPECTS

We will present two experiments described in

sections 4 and 5, considering two aspects: i)

Communication of the possibilities of interaction

with iDTV for members of the team involved in the

case study described in this paper, and ii)

Participation of some target users of this technology

in design sessions both to explore new ideas and to

validate interaction design solutions. We will

explore each aforementioned aspect, presenting

experiments in which the following sentences will

be discussed:

1) The theater technique leads to an effective

communication process of the interaction design

solutions. Effective communication is understood to

be a process in which the supply or exchange of

information, ideas and feelings occurs, through

written or spoken words, or through signs, resulting

in a reciprocal comprehension and shared meaning.

2) Practitioners of theater techniques can easily

observe the players’ emotional reactions. The

players become motivated and provide the

practitioners with relevant ideas (suggestions,

actions, opinions). In the context of this research,

such ideas and users´ reactions help professionals to

better understand the dynamic of the interaction

context and to reflect on the implications for design.

The activities that will be described next are part

of a process of definition of the users’ needs for

products that will be generated by a research project,

called SAMBA (System for Advanced interactive

digital television and Mobile services in BrAzil)

(Blind Review). Those involved in this multi-

cultural project are: Brazilian and Italian users, as

well as stakeholders from 9 European and Brazilian

organizations, including 2 universities.

Project SAMBA pursues the creation of a

framework for enabling local communities—

including low income populations—to participate in

PROMOTING COMMUNICATION AND PARTICIPATION THROUGH ENACTMENTS OF INTERACTION DESIGN

SOLUTIONS - A Study Case for Validating Requirements for Digital TV

269

the process of creating and accessing digital content.

The main SAMBA product is Web software to

produce content (called Content Creation Factory or

CCF) and make it available through services that

will be accessed by iDTV and/or mobile devices.

Therefore, the stakeholders had to discover which

services would be more interesting to the

communities. Two user field studies (one in Brazil

and one in Italy) were launched (Blind Review). In

Brazil, the user field study took place in the town of

Barreirinhas. In Italy, the user study took place in

the province of Alto-Adige-South Tyrol. These

places were chosen for having received financial

support in previous European projects to install an

electrical structure on several streets and that will be

needed here (Opera, 2007).

In Italy, Digital TV is a reality, but it is not the

same in Brazil. The deployment of the Brazilian

Digital TV System (SBTVD) requires the

preparation of broadcasters of the national digital

TV for transmission. Deadlines were established to

start works on transmission of TV content in this

technology in the country. The expected date to

access this technology in small municipalities in the

northeast, as in the case of the study, is for 2010. In

the Samba project, it is expected that the

transmission starts in 2008. Concerning the benefits

with the results of this project, we can say that the

SAMBA environment developed to access content

through the digital TV can be compatible with the

SBTVD. It is based on some characteristics, such as

the adoption of JAVA-TV of the HAVi standard,

and GEM (Globally Executable MHP)

specifications, which are common to both the

Japanese (Standard adopted by the Brazil) and

European standard (Furtado et al, 2008).

Next we will present two experiments, both

occurring in Brazil: the first one concerns the

communication among all the stakeholders at the

laboratory site, and the second one concerns the

participation of the Brazilian users and takes place in

their real context of use.

4 EXPERIMENT 1

4.1 Method and Participants

In order to present the results of the Brazilian and

Italian users´ studies to the stakeholders, we

accomplished a meeting, which took place in the city

of Fortaleza, Brazil, from July 2

to 4

, 2007. 27

(twenty-seven) stakeholders were present, of which

8 worked on the organization of this event and 4

were responsible for the definition of the interaction

design of this project.

On the first day, we initiated the presentation of a

comparative analysis of the results of the studies on

the topic researched (Blind Review). Next, we

intended to communicate important messages about

the interaction scenarios of users targeted with the

iDTV services.

For this project, 4 iDTV services were identified:

1) discussion, which allows the interaction among

viewers through the TV; 2) visualization of

information on TV; 3) surveys, to promote the

participation of the community, and 4) entertainment

– manipulating digital pictures, to guarantee

involvement with the digital content. The relation

among scenarios and services is the following: each

scenario highlighted at least one service, and one

service can be pointed out in several scenarios

described.

The expected contents and applications that are

targeted with these iDTV services will support

health and education problems. So, community-

oriented applications, as the gallery-photo

application, are intended to be used both by

Brazilian and Italian students to build and share

digital contents.

Many stakeholders were not familiar with the

reality of the studied users and they had different

background about DTV. Some (n=7) had not yet

worked with scenarios and storyboards before.

It was necessary then to use a resource that

would promote the homogenization of the language

for the understanding of the purposes of the verified

interaction scenarios. We invited the participants to

join us at the theater.

The theater presentation was 30 minutes long.

When the performance was over, there was a

moment of great emotion brought on by the surprise

of the artistic production. On this occasion, the

actors involved in the presentation were

acknowledged. Next, all the participants returned to

the meeting room and a discussion was begun. To

hark back to the interpreted situations, professionals

used slides in which there were storyboards and

scenarios associated with each play. At the end of

this discussion session, a questionnaire comprised of

5 open-ended questions was applied. The questions

were related to the importance of the strategy

applied to the understanding of aspects of the

interaction scenarios, and the services to be offered.

Only 15 participants answered the questionnaire,

since the other 12 were directly involved in the

interaction design and communication strategy.

4.2 Production of the Theater Script

To produce the theater script, the following steps

were realized:

1. Definition of the following elements for the

production of the theater performance: The script—

which relates the story (the scenarios) to be

interpreted—is added to interpretation resources,

such as demonstration, simulation, error treatment

support, help, integration and socialization. The

stories to be interpreted had a narrative of

approximately 15 lines;

2. Choice of actors and wardrobe. In order to

take full advantage of theatrical techniques, we

explored the use of theater professionals (6 actors, 1

playwright, and 1 director). Each story had an

average of 3 actors, who were students from the

University where this research took place and were

part of a theater group. Each actor represents a

persona that is used as examples of the specific

public that will use the proposed system in the

scenarios. There was a rehearsal of the performance

with the participation of the HCI professionals

(authors of this paper), the actors, the writer, and the

director. Important issues were discussed in order to

bring an emotional content to the narratives; and

3. Organization of the ambience, lighting, and

sound. In addition, all of the audio-visual resources

used to videotape the plays were installed.

4.3 Stories Communication in the

Theater

The audience was comprised mostly of non-

Portuguese speakers. Therefore, we choose to have a

presentation in which there was no dialogue among

the actors/characters. Thus, the characters expressed

the entire aforementioned dynamic through

soundless actions and, to aid the comprehension of

the story, a narration in English described what was

happening in each scene. Six different plays were

presented. All of the comments were made at the

end of the presentations.

Figure 1 illustrates a few passages of a story told

in the theater presentation associated to certain lines

of the script. A teacher (the “Antonio” persona)

learns that a student (the “Junior” persona) is sick

and will have to miss two weeks of classes (Figure

1.1). After some time reflecting on a way to prevent

his student from missing the content given in class,

Antonio decides to prepare slides of his class (Figure

1.2). After the class is over, Antonio tries to send the

slides of each class over the internet, at first he has a

little difficulty, but as he tries a more few times, he

is able to achieve the task without the help of

another person in the scene (Figure 1.3). After being

successful, the video becomes available for the

entire class. Junior, who is at home sick, turns on his

iDTV and finds the slides without any difficulty

because he is well-acquainted with the technology

(Figure 1.4).

Figure 1: Scenes presented in the theater performance.

As we mentioned before, a second experiment

was performed to communicate the defined

requirements to Brazilian users, which is the subject

of the next section.

5 EXPERIMENT 2

5.1 Method and Participants

The activities of this experiment were performed

during our second trip to the town of Barreirinhas,

Brazil from October 24

to 27

, 2007. These

activities aimed to: i) inform residents about the

iDTV services that were chosen to be implemented

based on their needs. As previously mentioned, these

needs were gathered by professionals of this

research from a user field study that took place 8

months prior, on the first trip (Blind Review); and ii)

explore new ideas and evaluate the design proposed

for these iDTV services.

This experiment included 32 (thirty-two)

participants (residents and workers), who were

obtained from a list prepared with the names of the

participants of the experiments of the 1

trip.

However some participants were added to or

removed from this original list. Just 9 users

participated in all studies on both trips; the others

(11) participated only in this experiment. The

implication of this problematic was that the

professionals of this research had to repeat a

presentation that showed the interaction possibilities

of existing iDTV applications and an explication

PROMOTING COMMUNICATION AND PARTICIPATION THROUGH ENACTMENTS OF INTERACTION DESIGN

SOLUTIONS - A Study Case for Validating Requirements for Digital TV

271

about SAMBA project goals. Participants could also

use these applications to understand better the

technology.

We held 5 workshops. Each workshop included 5

to 9 users organized by themes (such as

entertainment, communication, business, retirement,

and content production).

The workshops lasted an average of 5 hours and

were accomplished by 4 professionals, being 2

professionals in Usability (one of whom is the

author of this paper), and 2 professionals from the

area of the Cognitive Psychology. Each workshop

was organized in three moments: i) Moment of

reception, which consisted of a presentation of the

main goals of the workshop and having as a

resulting artifact the informed consent by the users;

ii) Moment of presentation of the recorded video

illustrating the theater performance of the first

experiment; and iii) Moment of enactments, when

scenarios were acted out by users in their own

physical and social environment and cultural

context. Participants received a script similar to the

one they watched in the recorded video. In the script,

they were encouraged to act out scenes using

computers, cell phones, remote controls and TV sets

in order to visualize content, and/or to access iDTV

services or to produce content. The given script was

not the same for the following reasons: i) in the

plays, we had just three actors, here we had a higher

number of participants; ii) the participants were

motivated to explore different characteristics and

needs of every other participant; iii) the content had

to be related to the participants’ own interests; iv)

we wanted them to act out the scene in their own

context of use (not in a theater building, as shown

before); finally, v) we wanted them to be free and

not to influence their way of thinking.

The next two sections refer respectively to users’

engagement in the second and third moments,

mentioned above.

5.2 Illustrating the Theater with

Prototypes

Each workshop only worked with the parts of the

recorded video that illustrated the scenarios in which

the characters involved represented the categories of

the participants in that workshop.

Figure 2 illustrates a group of participants

watching the recorded video making comments and

opinions on the scenes. To improve the participants’

understanding of what the characters did while using

a particular device, we inserted the low-fidelity

prototypes into the scenes of the theatre. The

prototypes did not present any graphic layout of

either iDTV applications or CCF for web. They were

aimed at illustrating the functionalities visually

described in the scenarios.

The prototypes were in Portuguese because they

were applied in the process of validation of Brazilian

users’ needs. When these prototypes will be used to

validate the Italian users’ needs, English and Italian

versions must be generated.

Figure 2: Users watching the video.

The professional who moderated the session

rewound the video as often as necessary. It was not

her goal to validate the user interfaces shown. This

is the reason she did not encourage them to use the

prototypes. The professional took notes of all the

participants’ opinions and reactions.

5.3 Enactments in Experience

Prototyping

After the video presentation, the professionals

initiated this third moment, telling participants that

they will assume different roles in order to show us

several real-life situations using iDTV. Specifically,

it was a dual-task experiment: first they had to

elaborate a script and afterwards they acted it out.

We asked them to focus on successful

experiences, illustrating the benefits of this

technology in their lives and for the entire

community. Barreirinhas is a town that is destitute of

households and other places with direct and

continual contact with computers. Residents usually

access the Internet through coffee shops, offices or

schools. The town’s socio-economic conditions

generally do not favor the existence of a good

communication structure (such as broadband internet

access), but residents make the most sophisticated

acquisitions of cell phones and TVs.

Participants were told that their cooperation was

very important because the more the situations were

representative of their needs and lives, the more

efficient the play would be to us. Consequently, we

could come back the next year with a system that

would be most appropriate for them. We also said

that they could improvise the way in which they

ICEIS 2008 - International Conference on Enterprise Information Systems

272

interact with the devices and/or with the other

players.

Each experiment took from one to three hours, with

the participation of a moderator. The participants

had several rehearsals until they were satisfied. The

moderator made a few interventions, only when it

was necessary. Technological errors were

immediately clarified, as for instance, there is no

need to turn on the Set-top-box when a content

producer uses the web system to create content that

will be broadcast to TV afterwards. Participants

performed their tasks using several resources, such

as: papers, appliances, electronic devices, and

prototypes.

Figure 3 depicts a scene performed by a group of

teachers (participants) in a school room. They are

playing two activities: first they evaluate the results

of a poll (an iDTV service), which was obtained

through an iDTV application. All of the school

communities participated of this poll to choose the

theme about the culture of the town to be studied.

Then they define the strategies to describe the theme

by pretending they are using the CCF.

content using SAMBA products.

6 RESULTS

In this section, we will describe the results by

addressing the purposes of the application of

theatrical techniques to communicate interaction

design solutions related to the first experiment

(section 4.3) and to promote participatory design

related to the second experiment (section 5.3).

6.1 An Analysis of the Theater

Technique as a Resource to

Communicate the Purposes of

Interaction Scenarios Objectively

Comments provided by the stakeholders (which

were collected by applying a questionnaire after the

theater presentation) were analyzed. After similar

and convergent answers were separated into groups,

the three categories were identified: Understanding

the services to be offered; Communication Type,

and Involvement with the Content. To identify the

comments, the letter “S” (for Stakeholder) was

adopted, enumerating it according to the quantity of

people that participated in the study.

The category Understanding the services to be

offered refers to a way of knowing and

understanding, in a unique way, of the purposes,

benefits, and solutions that Project SAMBA is

capable of providing. The highlighted comments of

S1 and S3 provided this affirmation: “It was an

important point to clarify the Samba objectives” and

“The scenes represent the diverse situations that the

users will experience with SAMBA’s products.”

Other participants felt as if the hypothetical

situations presented in the theater performance were

real, thereby establishing diverse connections with

the concrete situations. The phrases: “It shows real

life” and “The scenarios were quite realistic” said by

S1 and S13, respectively, confirm the foregoing

definition.

In the category Communication Type, several

aspects were considered, such as objectivity and

clarity of communication, in order to avoid

blockage, noise and filtering-elements that

characterize a type of communication that does not

occur in a proper way or that is not successful in its

objective of communicating. It is understood that the

rhythm in which the scenarios were presented

contributed to the pragmatism, objectivity, and

quickness of the message. We were able to observe

the valorization of these requisites by S14 and S10:

“It is more direct, easy, engaging with the content

than a written explanation.”

Referring to the category Involvement with the

Content, this is observed in the audience’s feeling of

credibility in the level of development of this study,

their opinion about the characteristics of Project

SAMBA, and their feeling of valorization for being

part of an original study. Therefore, we point out the

following comments: “I felt comfortable seeing

images in action a plus words (and not just words),

because it made the transmission of ideas and

concepts clear, obtained during the process of

defining users’ needs (the results of users’ field

studies)” said by S7 and “It was a nice work, and

I’m proud of participating of this team.” said by S

11.

6.2 An Analysis of the Theater

Technique to Explore New Ideas

with Users

During the enactments, participants represented their

ideas and behavior in an improvised and

spontaneous way. We analyzed their representation

and will discuss here their contribution to this

project according to the following important points:

Definition of New Requirements. Participants (5)

(aged from 13 to 25) that worked with the

Communication theme took roles to rapidly organize

a meeting with several teenagers of the town. They

played using several devices, but the cell phone was

the most important device for the fastest

communication. Taking into account their

familiarity with this technology, they interacted with

several friends by sending messages that were seen

on their friends’ TVs. This play allowed us to gather

new technological insights (such as having

interaction with TV through SMS). Requirements

and information expressed by users were written

down for analysis and definition of priority;

Users´ Acceptance to use this Technology. In

(Furtado et al, 2008), we have described an

investigation about the appropriation of Digital TV

by the users identifying issues related to the non

acceptance, influenced by the way the technology

will be owned, by the topology of the city and by the

life style of the population. Human and contextual

factors help them to overcome these issues as soon

as the fact that this project is funded by the

European Commission;

Behavior of the Players. Usually almost all of the

participants acted, while a few took the role of

audience. This happened particularly in the group of

elderly people. From 9 participants, just 6 played

roles (such as lawyers and judges nearing

retirement) to represent the problematic of getting

information about their retirement rights. We did not

force those who wanted just to be viewers.

Sometimes they contributed to the scenario being

presented by giving their opinions during the

rehearsals;

Improvisation. As we expected, no group tried to

play a scenario following the drawings of the service

prototypes. Instead they pretended to be using a

SAMBA product. They wanted to be free to interpret

a situation they have often and they did not feel

comfortable with the details of this new way of

interacting;

Sense of Responsibility. When Content producers

played strategies to describe contents, they were

very concerned with involving the community in the

content production. They realized that content

producers cannot continue to operate in the same old

ways. The business model for Digital TV should be

similar to the web model, in which users can create

their own video and post it. The success of this play

made us select this group to go on working with

people of the town in order to elaborate a network of

content producers, which entails a culture of

convergence and;

TV in Social Spaces. Social contexts have a strong

impact on the attitudes of TV viewers. In many

scenes, watching TV appeared as a group activity.

Viewers eat together and make comments while

watching TV. This attitude shows the social value of

this communication resource. We propose these

results to be better explored afterwards in order to

redesign interactive resources and promote

interaction by groups.

7 DISCUSSION

Presenting videos to users brought a number of

benefits to the project: i) it was possible to show the

results of the user field study in an entertaining way,

and with no travel costs to bring all of the theater

professionals; and ii) it worked as a persuasion

technique in function of the quality of the scenes

shown in the video. These aspects encouraged

participants to have this “sophisticated” TV (as they

called it) in their homes.

Users were very attentive to the contexts

experienced in the scenes (town, schools, hotels,

etc.), and wanted to know which households, shops,

organizations of Barreirinhas will get digital TV. We

gave them explanations about the

telecommunication infrastructure that was necessary

to have in order to provide viewers with interactivity

on TV and return channels. The beneficiaries have to

live or work in the area having this structure.

In summary, the situated and participatory

practices described herein led the participants of the

second experiment to relate their real situations with

imaginary solutions of iDTV services. The analysis of

these practices allowed professionals to further the

understanding of how the services will be used by

identifying: i) what services´ characteristics (as price,

credibility, social activities, etc) elicit positive

emotional responses (as pleasure, happiness,

acceptance) from users, ii) in which environments the

services will be used (in public or private spaces),

and; iii) with whom and by whom (as the potential

content producers) they will be used. In addition,

professionals could reflect on the implications for

design. They defined new requirements that, upon

ICEIS 2008 - International Conference on Enterprise Information Systems

274

acceptance, can lead to adding new services in the

product explored in design sessions.

As an open question, we can highlight that since

realism is important to explore new ideas and

validate a design proposal, it is important to improve

our ability to gather empirical data in the most

realistic settings possible. The field study presented

as part of our second experiment begins to address

this need by demonstrating the effectiveness of the

role-playing experience in situ. However, it remains

an open question how to improve our ability to

simulate real events occurring (such as interruptions

in the broadcast of a TV program) that have some

influence on the users’ behavior and on their

difficulty in using the technology.

8 CONCLUSIONS

In this text, we argue that understanding the users’

needs with technology is a difficult task to

accomplish for professionals responsible for the

development of innovative technologies.

We showed that feedback from users comes from

different ways, and professionals should provide

them with opportunities to express their emotional

reactions as if the technology were part of their

lives. Experience prototyping strategies matched to

theatrical techniques were used and provided the

professionals of this case study with useful

information about users and their context of use.

We also showed how to properly communicate this

understanding to the other members of the team as well

as to the users themselves. Several situations were

played, videotaped, and after analysis, interaction

scenarios were (re-) defined, illustrated and played in

participatory design sessions in an iterative way.
