Usability in Ubiquitous Computing and Interactivity
Once upon a time, we used computers exclusively at our desk to look for information, or to use a specific application. But, increasingly, computing devices are becoming an extension of human experiences, as we go about our daily schedules. Event-based, contextualized presentation of information is introducing new demands to the usability factor for applications running on mobile devices. Now, more than ever, usability needs to hone the user experiences that are enabled by ubiquitous computing.
To consider the implications of the lack of usability in a mobile application, the interactivity modes in which a user incorporates its capabilities into their daily flow, need to be analyzed. A badly designed interface in a mobile application, which is used in short, five-second episodes throughout several periods during the day, can cause a lot of pain for the user solely due to the frequency mode. Other high-context applications need to take a deeper anthropomorphic view of the users’ needs to ensure that specific interactions deliver the usability components for a superior experience. A lack of insight into these aspects will cause the user to abandon the application due to the mismatched impedance. [Read more…]
