A house that knows where you are and understands your behavior

In near future, a house that you live in will know where you are and automatically adjust its configurations such as switching on the light of the room when you enter the room. Your walking paths over long period time can be recorded and then analyzed statically to recognized the behavior pattern. The automatic recognition of behavior pattern is very useful in elderly care to detect the behavior changes in elderly people living all by themselves. For the task of localizing persons in the room, one would use radio based tracking technologies. However, these technologies require attaching electronics device to a person to be tracked. To tackle this limitation, a visual tracking technologies can be used as low cost digital cameras are widely available nowadays. The limitation of the low cost digital cameras in this application context is that view from a single camera is often not enough to cover the whole room. Thus a network of cameras is used to sufficiently cover every room in the house. Each camera estimates a person’s 3D locally using computer vision techniques. These estimated positions are sent to central controller to make more reliable and accurate joint estimates
