Paper Abstract:
|
Broadcast TV to mobile terminals is becoming a reality in many countries. This paper describes an implementation of a
broadcast quiz game program targeted for pass-time purposes for the mobile user. The game show consists of a sequence
of video clips, along with associated questions and answer alternatives displayed as text. The users answer is sent via
SMS to a game server, which collects points and sends the final score back to the user. Adapting the quiz to the small
screen of a mobile phone poses problems related to placement of the text relative to the video as well as displaying the
text with sufficient resolution and clarity. Burning the text into the video before transmission has acceptable legibility,
but does not allow flexibility in placement or language selection; hence generating the text overlay in the terminal is the
preferred solution. Synchronizing the display of the text overlay with the video clip is also challenging. Current
technology allows only approximate solutions to this problem. It is shown that the in-built user interface for interactivity
on the terminal that we have tested (Nokia N96) is not well suited for a fast changing quiz game. Therefore a better suited
client must be supplied with the quiz game for easier user interaction. A final problem is to correctly time the answer
supplied by the user so that it is associated with the right question. The mobile phones in-built interactivity interface is
not capable of solving this satisfactorily, so that a dedicated quiz game client is required also to handle this problem
without any compromises. |
