Mobile devices and services are rapidly becoming the preeminent conduit for human computer interaction. This talk will focus on two areas of research in this domain. The first looks at the user experience of watching videos on mobile devices and the second explores how mobile applications and devices can be enhanced for use by illiterate people.
Mobile services rely on wireless spectrum, a shared and scarce resource that service providers like to allocate economically, especially for resource intensive multimedia applications. Therefore, they need to know at which point the user experience becomes unacceptable due to under-resourced video quality. My research has explored these limits of user experience and how they should be measured. I will describe how a mix of quantitative and qualitative approaches has provided evidence that the user experience cannot be properly understood through the common approach of video quality but requires the more comprehensive notion of visual experience.
I will also highlight some of the design and methodological challenges that appear when creating and evaluating mobile applications for and with illiterates users based on ongoing research that I am conducting as part of an ICT for development project in rural India.
