| Abstract: |
| As people grow older, their memory will continue to decline. They often can not find some items in their daily lives. This paper presents an object searching system in smart home. Similar to the Web search engines, it can return some relevant information about the searched object for the user. The system uses UWB devices for indoor object localization. It obtains the user’s current context information by using various sensors in smart home. Thus, with the user’s original search input, the system can infer the user’s real search intention, and then offer intelligent search services. |
