lights the value of the RxD framework in developing
health applications and suggests potential for its wider
application in this field. As technology evolves novel
solutions are needed to facilitate patient’s active in-
volvement in their healthcare. RxD can play a central
role in finding such approaches that align with patient
needs.
Our headache diary prototype, redesigned using
the RxD framework and incorporating NOW Interac-
tions, received positive feedback, indicating its poten-
tial to integrate with or complement existing headache
diary apps. With 5-10 users often revealing most us-
ability issues (Nielsen, 2012), our six participant us-
ability study provided valuable feedback for interface
improvements, despite not confirming clinical valid-
ity. Larger studies, including clinical validity eval-
uations, are necessary for comprehensive validation.
Our usability study is a preliminary step towards this,
aiming to refine user interface and interactions with
individuals sharing similar traits to our target users
before advancing to clinical trials, thereby enhancing
future trial reliability and minimising patient incon-
venience. Future research should also explore per-
sonalisation in self-report and NOW Interactions to
meet individual patient circumstances and needs, po-
tentially balancing simplicity and utility. Adjustments
in interaction timing and presentation, the nature of
requested data, and data presentation and display can
reduce perceived respondent burden and enhance rel-
evance for both patients and healthcare professionals.
The data in Table 1 reveals that both the simplest app
and the most feature-rich app received high user sat-
isfaction scores. This could imply the need for a bal-
ance between simplicity and utility. Future research
should investigate how both offering minimalist log-
ging mechanisms, such as NOW Interactions, and ex-
tensive in-app features can provide users with the flex-
ibility to choose based on their immediate needs and
conditions.
5 CONCLUSION
In this paper, we demonstrated the value of the RxD
framework in the context of redesigning a headache
diary. By adhering to the framework, we were able to
understand the unique user context, notably the pain
and discomfort that directly impacts cognitive abili-
ties. We identified the critical needs of the diary to
include timely and accurate information logging and
a simple information retrieval process. In response
to these identified needs, we proposed a design solu-
tion using NOW Interactions. This solution allows for
seamless headache logging without the need to open
an app, a design choice aiming to minimise the cog-
nitive load on individuals suffering from headaches.
Evaluations showed users appreciated the reduced
necessity to open an app for every data log. This per-
spective was reinforced by a neurologist, who empha-
sised the importance of simplifying the data registra-
tion process for patients. Compared to existing so-
lutions, the NOW Interactions solution has cut down
necessary interactions by over 50%. The results sug-
gest NOW Interactions can alleviate respondent bur-
den and enhance data quality by promoting timely in-
teractions and streamlining information retrieval.
The research showed the potential of the RxD
framework and innovative interactions to enhance
user experience in medical self-report diaries, with
the overarching goal of reducing respondent burden.
Future research could explore using the RxD frame-
work to design a headache diary from the ground up,
building upon the insights from this research to push
the boundaries of patient-centric innovation.
