Goal/Purpose of the Project
The purpose of this project is to use Activity Theory to (1) understand how users’ experiences
(UX) with mobile devices differ from typical desktop or laptop personal computers (PCs), and (2) create
assessment and design guidelines to foster more positive and personal mobile device UX.
Importance of Project
How should smart phones vs. tablets vs. desktop websites and web applications be designed to
foster positive user experiences? Today, the answer is – we don’t know. People are adopting and using
mobile devices (e.g., smartphones and tablets) at exponentially rates. People use their mobile devices in
different ways than PCs: including, quickly satisfying just-in-time information needs, accessing real-time
location-based information about their immediate world around them, and entertaining themselves at any
time in any place; even though their mobile devices have much smaller screens that limit what information
people can easily see and constrain how people interact with their mobile devices. Mobile software
applications allow abundant personalization of mobile devices, and advances in interaction technologies
(such as touch screens, virtual keyboards, voice-activation software, etc) allow users to more easily use
these devices. These factors have created highly coupled, dynamic, and more personal connections
between users’ and their mobile devices, compared to connections between users and their PCs.
Consequently, it is commonly recognized among academia and industry UX professionals that assessing
and designing positive mobile user experiences require fundamentally different approaches from the
typical assessment and design of UX for traditional desktop or laptop computers.
There is a lot of academic research and industry advice about the UX assessment and design of
webpages, PC software, and specific mobile technologies (Benbunan-Fich et al. 2007; Betiol et al. 2005).
However, no research was found that could explain why and how UX differs between mobile devices vs.
PCs. There is little research that exists about how mobile devices fit into people's lives (intentions, tasks,
affect, etc.), why people respond differently to different mobile user interfaces, and how users’
experiences with mobile devices are different compared to traditional computers. Practical UX
assessment and design guidelines are needed, based on sound, repeatable research, to help us
understand how to create more positive mobile user experiences for people using smart phones vs.
tablets vs. laptops vs. desktops interfaces.
Proposal
Using Activity Theory, we propose to design and conduct a study where data is collected from users of
new mobile devices from two different organizations. Dr. Swan and I are currently trying to develop
mobile applications to help evaluate BYU Nursing students in doctors’ offices, and a local company that
provides communication and notification services to parents and students in school districts.
After I approached Dr. Swan with the idea for this study, Dr. Swan taught me that Activity Theory provides
a framework and method for assessing the interaction between user intentions, users’ tools or artifacts,
and context of user to produce outcomes over time. Acitvity theory has been recommended and used in
UX and usability research for two decades (Kuutti 1995; Nardi 1998); yet, only a few studies have applied
it to study of mobile devices (Zurita et al. 2007). We found no studies that use it to study the differences
between mobile and traditional UX assessment and design.

Fit With BYU’s Mission
Disseminating research-backed information to academics and industry professionals will go a long way to
helping a lot of people have better user experiences with they mobile devices, thus helping advance
human potential. This project also creates a “stimulating setting” for me to learn because it enables me to
pursue more advanced learning about my desire to learn about mobile UX design. This project may also
stimulate life-long learning in a variety of people. If people have better experiences usin their mobile
devices because of our research, we may influence them to learn more about themselves and the world
around them, as well as improve their quality of life.
