O-find / smart assistant device


O-find is a home assistant device that helps the elderly to find things at home when they forget where it goes. By sticking the RFID tag to the item and setting sensors on the doorframe of rooms, O-find records each move whenever the item passes through from a room into another. When the user is looking for things, such as keys, pills or phone, the App shows the room where the item was last recorded. In addition, by setting a go out checklist, O-find can serve as a reminder when you left something inside the house.
