active networks, peer-to-peer computing, user interface, a
dynamic multiple location streaming multimedia
Streaming multimedia applications over the Internet to
mobile device or remote client is still facing the problem
of client heterogeneity in terms of bandwidth capacity and
user's preferences on the perceived video quality.
Addressing this problem, user-friendly active Network
system (FANS) is designed and implemented on the basis
of active network paradigm where intermediate peer
computers adapts the bandwidth consumption of the
streaming media heading to the destination into the
desired level either by reformatting the media file or
rescaling the media presentation size.
While FANS proves reliable in reaching the client with
poor bandwidth, we need to make obvious that the user
interface of the system is simple, self-descriptive and
encouraging for the users. The paper is devoted to
describe the design considerations, the implementation
and the functionality of each user interface components.
We identify five attributes that should be considered in
designing a user interface for dynamic, multiple locations
streaming multimedia environment, which is the case of
FANS. The user interface considers thoroughly the five
attributes and has been reliably and conveniently used in
hundreds of tests of FANS' performance evaluation. Last,
the user interface also conforms six principles of the
usability heuristic rules.
