Wazzup?

We had to tackle a bunch of problems that came up during the design. Some are general problems when designing a mobile application, some are specific to our application:

Limited screen space: cell phones have screen space but information must still be presented in a pleasing and easy to use way.

Privacy: Since our application automatically gives away some information to others, we had to take privacy issues into account.

Asynchronous communication: The scenario and our persona data showed us, that we cannot assume that everybody will use our application at the same time, so all communication will be asynchronous.
