Abstract: Mobile devices as smartphones or PDAs are common in our daily life. Museums and art galleries provide
electronic guides in order to do more pleasant a visit or exhibition. The problem tackled in this paper is to
prove the suitableness of using a PDA, instead of the traditional guides. In this case an application was
specially developed to provide users that are visiting the museum additional information and help. It is
interesting to know how to adapt these devices to guide and improve visitors’ experience. Moreover, we
have to take into account that technology should not be the centre of attention in art museums or exhibitions,
but it should be unperceivable. Thus, in this paper, we describe an evaluation of a real system deployed in
an emblematic museum in Spain, called Cutlery Museum of Albacete. Our approach offers visitors a PDA
that employs a wireless network to show additional information about old knives, jack-knives and scissors
which are exhibited in the museum. In this way, art and technology are combined with success. The system
supports four languages and incorporates special functions for disabled people. This article shows the users’
satisfaction results collected during the last 18 months. These results lead to a detailed analysis suggesting
some improvements for future versions of the software.
1 INTRODUCTION
The application of mobile technologies to Museums
and exhibition environments in general has been an
area of special research interest in the last years.
Particularly, the use of wireless networks has
improved considerably this new way of accessing
information in a ubiquitous way within these
environments. Undoubtedly, these emerging
technologies can be used to enhance interactivity
among museum visitors.
Concretely, in the city of Albacete, Spain, there
is a museum dedicated to exhibit valuable and very
antique cutlery pieces. This is the scenario in which
we have implemented these new technologies to
improve visitors’ experience when visiting this
concrete museum.
Interaction improvements in museum exhibits
using augmented artefacts are proposed in (Ciolfi
and Bannon, 2002). These improvements are usually
performed by experts in the area (students
volunteers, docents, etc.)
We think that these improvements may be
provided in some degree by an electronic device.
The system developed (Gallud et al., 2005) and
currently running in the Cutlery Museum of
Albacete has been designed to provide guidance to
visitors, and to show additional information about
the exhibited pieces, as well as other stored pieces
that are not physically available for the public. The
system has been running for 18 months, and during
this period several tests to measure the users’
satisfaction and opinion about the new system have
been performed.
In this paper we show the results of experiments
carried out with real users and extract some
conclusions from these results to improve the
system. As antecedent of HCI electronic guides test
we may mention (Steele, 2002).
The rest of the paper is structured as follows:
Firstly, we present the state of the art in the field
of new technologies applied to improve users
experience in art museums and exhibitions.
Then, we describe the software architecture of
the system and the evolution stages from the initial
to the current specifications.
As mentioned before, we are working with a real
system running in the Cutlery Museum of Albacete
and, at the same time, we are defining a new system

in our HCI laboratory. In this way, the evaluation of
the user experience is used to improve the system
under development.
Next, we describe three system evaluation
experiments performed on three different groups of
people, using the same evaluation survey. We have
followed the CIF (Common Industry Format for
Usability Reports) standard defined by the ISO/IEC
DTR 9126-4. These groups of people have been
defined according to the following parameters: age,
technology expertise and general public. After the
experiment description we expose the collected data
and the results of this analysis.
We finish the paper with some conclusions and
final remarks as well as future actions.
As a conclusion of our work, we show that the
use of PDAs in art museums may improve users’
experience and increase the overall satisfaction of
different visitors. This research also revels that it is
necessary to make an additional effort to turn the
software client for PDA into a real good tool rather
than an obstacle between the visitor and the
exhibition.
Some of the conclusions extracted from this
work will be applied in the definition of a new
system.
2 THE USE OF NEW
TECNOLOGIES IN ART
MUSEUMS
People related to museums and libraries were
focused on using electronic technology for more
than 20 years. It started with electronic libraries and
was enforced with the introduction of Web
technologies. Web technologies offered new
opportunities to open up the walls of the museum to
the world (Schweibenz, 1999), an opinion shared by
several researchers in the field (Dolgos, 1999), (Falk
and Dierking, 1992, (Jackson, 1998), (McKenzie,
1998).
A pioneer on this line was The Museum
Educational Site Licensing Project. This project was
from running January 1, 1995 until June 30, 1997. It
was jointly launched by the Getty Art History
Information Program and MUSE Educational
Media. They were supported by the Association of
Art Museum Directors, the American Association of
Museums, and the Coalition for Networked
Information. The goals of the project were the
availability of museum images and related
information delivered over computer networks for
educational use and to show the value of digital
media in the study of art and culture.
Another important initiative was the Art Museum
Image Consortium. (AMICO)
1
It was also a not-for-
profit organization composed by 23 North American
art museums that was founded in October 1997 and
dissolved on June 2005. The aim of this consortium
enabled the educational use of museum multimedia.
Nearer to our days, the Virtual Museum of
Canada
2
, launched in 2001, has an average of
500,000 visits a month to its half-million images
(Green, 2004).
Latest online examples are the MIA
(Minneapolis Institute of Arts)
3
and the Online
Archive of California, known as OAC
4
. The last one,
brings together historical materials from a variety of
California institutions, including museums,
historical societies, and archives. Over 120,000
images; 50,000 pages of documents, letters, and oral
histories; and 8,000 guides to collections are
available.
Currently, a new step in communication and
mobile technology seem to be leading the future of
art galleries and museums applications to mobile
applications. Mobile devices are becoming very
common among people. Such devices are light and
easy to use; these features combined with a
decreasing price and a growing processing power
turns these devices into a powerful tool to develop
m-applications.
Indoor and outdoor exhibitions may take
advantage of mobile technology giving visitors the
experience of new feelings about pieces. Augmented
eality applications may be implemented providing
multimedia extra information to the user.
Information that is really difficult to present
otherwise.
A study involving a comparative evaluation of
different platforms for augmenting museums and art
galleries was presented as a part of (Baber, 2001).
Prototypes of the application were developed for
three different devices: a HMD (Head Mounted
Display), a PDA and a Tablet. The results of the
experience exposed that:
Effectiveness performance was higher in
HMD and PDA than in Tablets.
Best attitude rating was obtained by PDA
and HMD.
In broad terms, PDA tended to outperform the
other prototypes.
(Bristow, 2002) proposed two contextually-
aware mobile systems; one suited to the indoor
environment; and other one to the outside
environment. The first one was based on IR
technology; and the second one was implemented
applying GPS technologies.
An interesting approach was presented in
(Ciavarella and Paternò, 2003) where infrared
WEBIST 2007 - International Conference on Web Information Systems and Technologies
352
emitters were used to locate a user and provide him /
her with Location-aware information. Improvements
to original system were exposed in (Ciavarella and
Paternò, 2004) too.
The Cutlery Museum in Albacete (Spain) is an
emblematic institution of the city that is currently
using an electronic device (PDA) to guide visitors
through the museum. (Gallud et al., 2005).
A PDA connected to WIFI endpoint installed
into the museum is used to retrieve information
about pieces exhibited in the showcases. So people
are able to get information in different languages, to
follow predefined routes based on experts’
experience, and so on.
Next section describes in more detail the main
features of the system.
3 DESIGNING THE PDA-BASED
SYSTEM
In this section we describe the system that is
currently being used in a real scenario.
Flash technology was used to get a high quality
Graphic User Interface.
The Application starts showing a presentation
screen (see Figure 1). Afterwards, the user selects a
language to interact with the PDA device (see Figure
2). And finally, the user chooses how to visit the
museum (see Figure 3).
There are four options available to visit the
museum:
1. Guided tour
2. Recommended routes
3. Access to finder
4. Unguided tour
The Guided Tour guides the user through the
whole museum. It shows three controls: Previous,
Next and Piece to navigate across the museum
showcases (see Figures 4 and 5).
The Recommended Routes mode was designed
to guide users interested in specific subjects.
Samples of these roads may be knives of XVII
century or French scissors (see Figure 6).
In order to provide a search engine, Access to
Finder functionality is included into the system (see
Figure 7). Users are capable of searching
information by a piece or a showcase identifier (see
Figure 8), or by author, typology or date (see Figure
9).
Finally, Unguided Tour (see Figure 10) allows
users to visit the museum without any guide. So they
can freely navigate across the application to select
any piece in the museum and retrieve information
about it. Information is not constrained to text only;
but to images and audio too. Data is not bounded to
piece only, because the user is able to perceive the
context related to where the selected piece is
exposed.
Such space is organized in several screens: floors
(see Figure 11), rooms (see Figure 12), showcases
(see Figure 13) and pieces (see Figure 14).
4 EVALUATING THE USERS’
EXPERIENCE
In this section we describe the satisfaction
evaluation we have performed with different groups
of people.
The experiment embraces three aspects of the
application that will be evaluated to get the users’
experience satisfaction level:
Aspect 1: Graphic design and visual
impact.
Aspect 2: General usability
Aspect 3: Concrete functionality (i.e.
finding a showcase).
The experiment was performed by two groups of
users. Each group represents different user profiles.
The main idea is to contrast results of both
deployment scenarios.
The first group of users was composed by people
experienced in technical affairs; so they have some
knowledge about the technology being used.
However, the second group was composed by young
students between 13-16 years old without any
experience with PDA technology; so they are not
influenced by daily use of this particular technology.
To select groups of different profile, we
performed the same experiment in two public
events. Professionals belonging to the first group
were contacted in a technological event called
Feritec. Thus, from now and on, this group will be
referred as FeritecGroup. The amount of people that
filled FeritecGroup questionnaire was 75 (shown in
Table 1).
On the other hand, the second group was polled
in the V Science Week. Thus, from now and on, this
group will be referred as ScienceWeekGroup. 90
users filled the questionnaire described in Table 1 on
ScienceWeekGroup.

The experiment was carried out using the same
poll with both groups of people. This poll was
designed to capture user feelings about aspects
described above. It is composed by ten multiple
choice questions and each question has six possible
answers according to the user’s level of satisfaction.
Questions and possible answers are shown in
Table 1. Answers are ordered by level of
satisfaction, considering the least satisfying on the
left and the most satisfying on the right. Evaluation
of the aspects related to users’ experience
satisfaction are covered by these questions as
follows:
Aspect 1 is expressed on questions 1, 2 and
3.
Aspect 2 is exposed in questions 4, 5 and
10.
Aspect 3 is covered by questions 6, 7, 8 and
9.
To measure users’ experience satisfaction for a

An overall analysis is displayed in Figure 17. As
we can see, this application has an acceptable
performance; in both cases satisfaction ratings are
above 0.80. A little bit higher among young and
inexperienced people than adults that have some
experience in technology.
Now, a detailed analysis will be performed on
the results based on the three aspects that lead the
experiment.
First aspect, graphic design and visual impact,
will be analyzed first. Results reveal that the GUI is
more attractive to young people than adults (bars 1,
2 and 3). Difference is deeper when people were

asked about graphics quality and appearance. In this
case, we have the lowest levels of the overall poll for
FeritecGroup. However we get good marks for
ScienceWeekGroup.

Analyzing the second aspect, embracing bar 4, 5
and 10, we got good performance in bar 5 for both
groups (0.90 and 0.87); thus, the application is
accepted by people in general. However, young and
inexperienced people think that the application can
be improved on learnability issues. Assessing
usability in general, the FeritecGroup which is
composed by experienced people, thinks that the
application usability may be improved; while the
other group thinks it is ok.
When people are asked about concrete
functionality, represented by bars 6, 7, 8 and 9;
FeritecGroup is more comfortable than
ScienceWeekGroup due to the fact that these users
have a more fluent contact with this technology.
5 CONCLUSIONS AND FUTURE
WORK
Starting from the outcomes of the experiments
performed with real users, we can conclude that the
PDA application is generally well accepted among
both groups. Although experienced people may be a
little bit more exigent than people without
experience, rates are almost even. One reason of this
difference may be caused on the fact that
experienced people have more contact with this
technology, and as it is easy to perceive the potential
of this technology in this field, sometimes they may
expect more functionality.
The results revel that visual design is definitively
targeted to young people. As design and visual
issues are subjective matters and depends on people
profile, we may provide a mechanism to customize it
according to the user profile.
Regarding general usability, the application has a
good rating; although, as pointed in the last section,
learnability may be improved for inexperienced
people.
Application usability on concrete functions
showed poor performance ratings on inexperienced
people. We think that new interaction mechanisms
should be implemented to improve this issue.
On future work, we plan to address the issues
mentioned above. The following list summarizes the
lessons learned from these experiments and the
future work for the next version of the application,
which is currently under development:
To improve design and visual impact, a
skin based application must be
implemented. This function allows users to
customize application appearance
according to the user’s preferences.
Learnability will be addressed by using
agent technologies. We propose an assistant
to guide users through the application
functionality depending on their own
progress.
To improve interaction for inexperienced
people we propose a reduction of the
number of interactions that users have to
perform with the PDA in order to get the
required information. This objective can be
achieved using a location-aware system that
replaces user clicks by user position. There
are many alternatives to achieve this
objective. An approach using a wearable
computing device was presented in (Schiele
et al., 2001). Studies of location
identification were carried out in
(Ciavarella and Paternò, 2003) and
(Ciavarella and Paternò, 2004). So, it does
not seem to be an easy task to find the most
suitable one.
As suggested by (Grinter et al., 2002)
adding CSCW features to museums
exhibitions as a rich space in which to
examine this technology may emerge as a
promising line of work..
