In this article, we present issues and challenges
in design of successful mobile video chat
applications. Figure 2 gives a system overview of
the main issues in mobile video chat. Subjective
and objective user experience measurements,
privacy and secrecy concerns, current network
(communication channel) characteristics, enddevice
capabilities, and interoperability issues all
play a crucial role in providing the best user
experience to the end user. These issues will be
registered by a controller, which can decide the
right parameter choice for all components, while
resolving any conflicts.
