Description
Summary:This demo paper describes our daily activity sensing and recognition system with a wrist-worn sensor device called WristSense. The wrist-worn device is equipped with an accelerometer and camera, and can send the sensor data to a Bluetooth-enabled smart phone. With the accelerometer, we capture the wearer's hand postures and hand movements. With the camera, we capture visual information related to an object that the wearer is holding. An object that the wearer is using relates strongly to the activity that the wearer is performing. For example, an image (frame) including a coffee maker that is captured when the wearer is making coffee can be useful for recognizing the activity of making coffee. Also, a logger application on a phone records sounds related to daily activities. We use the sensor data in an attempt to recognize high-level daily activities that involve object use in real time.
