Mobile Interaction Design: Techniques for Early Stage In-Situ Design
Marco Montes de, Luís M. Carriço, Carlos Alfonso Duarte · InTech eBooks · 2008
So far, the work presented in this chapter has allowed the detection of several shortcomings on existing design methodologies when applied to the design of mobile applications and corresponding user interfaces. These findings, and the "on-the-fly" solutions that were used to cope with them, motivated the development of a methodology with techniques that apply specifically to mobile devices and ubiquitous applications. Globally, these problems led to the belief it was necessary to introduce solid guidelines on the various stages of design focusing on the mobility factor and on the users' varying context. On the data gathering processes, the updated techniques provided means for designers to gather contextual information by requiring users to complete questionnaires in-situ. Moreover, the use of audio recording when using the ESM method permitted a pervasive
