I returned from the Canon Expo Asia 2004 in the Super Brand Mall in Pudong, near the Pearl Tower.
The most interesting thing in the expo is the WebView Internet Camera. It is simple – just a camera with a 15V DC electricity power line AND a network cable. Plug it into any working network port and people can control the camera to move left/right/up/down and zoom in and out. There are some very interesting demos at their website. This is exactly what I was looking for and what I have tried to create one by myself. However, it is not available in the market in China and it is far to expensive for tech funs and home users. According to the staff in the expo, it is sold at around
100,000 10000 RMB in Japan now.
