A traditional experiment setup for studying sleeping pattern of fly was to place a fly in a glass tube. An infrared motion detector was placed in the middle of the tube. It detected fly motion if a fly moved across the middle, and the fly was considered awake. The conventional experiment is a passive approach. It loses information if a fly moves only on one side of the glass tube. In this thesis, we present an experiment setup that solves the problem occurred in the passive approach. Furthermore, we can design experiment that studies the impacts of social activities to the sleeping pattern. We used near infrared LED (wave length 850 nm) as the illumination light source which can be visible by a video camera that has infrared filter removed. A computer image processing was applied to compute the location of the flies. By comparing the previous and current locations of the fly, we derive the motion information of the fly. Our experimental results show that the proposed method can replace the convention method.
