In the process of semiconductor layer growth by metal-organic chemical vapor deposition (MOCVD), temperature measurement errors occur due to deposition on the reactor view port. This temperature shift is detrimental for the fabrication of devices. In this paper, an in-situ temperature and reflectance measurement system is developed for real time observations of process temperature and characterization...
Real-Time human motion tracking with Inertial/Magnetic sensors is a key technology in human-computer interaction applications. A computationally efficient and robust algorithm for estimating orientation is critical. This paper gives a quaternion-based orientation tracking algorithm for human motion tracking with a triaxial angular rate sensor, a triaxial accelerometer, and a triaxial magnetometer...
This paper introduces an arm motion perception and interaction platform using motion perception and touch/force interaction devices (wireless data glove, inertial tracking unit and force feedback device). The platform implements finger bend sensing, three dimensional motion tracking, and is able to feed back force to operator's hand on condition that it grasps the virtual object successfully. The...
