In this paper, a method of detecting object outlines and creating surface traces using a low-cost distance measurement array of infrared light-emitting diode (LED)-photodiode pairs is demonstrated.

This paper presents a low-cost novel motion tracking system using linear optical sensor arrays supplemented by a 9DOF inertial measurement unit. Each pair of the linear sensor modules is capable of ...
