The title of thesis is “User Experience and Usage of Mobile Services in Novel Contexts”
Mobile services are integral to the everyday lives of billions of users around the world. In the United States, over 77% of adults own a smartphone, and these adults use their smartphones for an average of 1.5 hours a day. Given this ubiquity, understanding the user experience and usage of mobile services is important.
Therefore, this work looks at the experience and usage of mobile services in several novel contexts such as using multiple mobile devices (like smartphones, tablets, and PCs) in parallel. As an example, the work suggests that for users with both a smartphone and tablet about half of their mobile usage time can be considered to include multiple devices. Therefore, mobile interaction designers should already consider multiple device contexts as ubiquitous rather than niche. Additionally, the work develops a multiple device session framework including formal definitions based on interval algebra.
Beyond the context of multiple devices, the work also looks at the context of multiple networks including the experience of using two mobile networks simultaneously and the context of long-term mobile service including the experience of using mobile services over several months or years. Overall, these novel contexts will likely become even more prevalent in the future given current mobile ecosystem trends.
