This paper presents a wearable eye tracker which is able to estimate the coordinates of point-of-gaze (POG) in 3D. By using this model, constructed by the glint (corneal reflection of IR LED) and the image of pupil center, the coordinates of POG can be estimated by calculating the intersection point of gaze-line (or visual axis) and screen. Aside from using in computer monitor, this eye tracker can...
In this paper, a physiological signal measuring system is presented. This system consists of a data controller, a RFID ring-type pulse/temperature sensor and a RFID reader, and a GPS. The physiological measurements obtained from the RFID ring-type pulse/temperature sensor and GPS data are transmitted by the developed data controller to the PC through either Bluetooth, ZigBee, or TCP/IP. The PC not...
The "long-distance home health care service" has become one of the key emerging businesses in Taiwan. In this paper, a mobile health management system is presented which is the first one integrating a wearable ring-type pulse monitoring sensor with a smart phone. All physiological measurements are transmitted to the smart phone through Bluetooth. The user can monitor his/her own pulse and...
In this paper, a single-chip-microprocessor-based multi-channel data acquisition and controller for mobile health monitoring system (MHMS) is developed. The presented controller separately interfaces with the high speed downlink packet access (HSDPA), GPS, and a ring-type physiological sensor by a multiplexer. Therefore, its cost is economical and its size is compact, making it suitable for mobility...
