System diagram of T-KTV.

The T-KTV system contains four basic components as the following pictures:
1) Webcam (1 or 2 webcam)
2) Projector
3) Attention Meter
4) Music video with flash movies

The webcam is used to collect participants' image streaming and project it on the wall for singer-machine-audience interaction. And the contextual data, including number of participants’ attention, whether they are moving, nodding, or shaking their head can be retrieved from the video streaming. Attention Meter is for analyzing the data from webcam video and determining the level of movements, especially for Tai-Ker dancing. A typical rave-party anthem "Mei Fay Se Wu" by Sammi Cheng is selected as the project theme. Flash movie is implemented based on the song. And finally, the interactive movie will get the values from the meter and reflect it on the projection.
