Many learning analytics techniques to capture the learner's real-time responses are computationally intensive for running on mobile devices. In this paper, we propose a personalized learning platform named the PETAL facilitated by an efficient learning analytics application to detect learners' level of attentiveness and the proximity of their eyes to mobile devices and then alert learners to be more...
The objectives of this paper is to develop a system for an autonomous mobile robot for searching and tracking sound source based target. The target can be a power charge docking station. Finding objects or events by following a sound source direction is an intuitive response for human and animal when they cannot see the target. However, there are relative fewer discussions about sound source tracking...
In this paper, a compact low power-consuming actuator for camera image stabilizer is designed and tested. The AC sensitivity of the actuator is 216 m/s2A, and the output force of the actuator is 0.281 Nt/A. By applying the thrust ball bearing to reduce the friction between the movable part and the stationary part, the minimum driving current can be less than 10 mA. The actuator can fulfill low power...
