Usability challenges in creating a multi-IM mobile application
Ohad Inbar, Boaz Zilberman · 2008
We describe the usability challenges of designing a mobile instant messaging (IM) application with voice (VoIP) capability. The key challenge was to maintain the experience of PC-based IM applications while taking into account both the constraints of mobile devices and the differences in the context in which such applications are used. We also discuss the challenges involved in implementing solutions to correspond with the capabilities and UI conventions of varied platforms and devices.
