Touchless hand gesture is one emerging technology for human computer interaction. In this paper, we investigate the feasibility of a hybrid system using frequency modulated continuous wave (FMCW) radar and ultrasound sensors with one transmitter and one receiver to detect hand movement for controlling a computer. Ultrasound will be used for near range application (1 cm to 30 cm) based on range estimation. FMCW radar, on the other hand, will be used for far range application (30 cm to 120 cm) based on range, velocity, and angle of arrival estimation. Leveraging these advantages of combining both ultrasound and FMCW radar will facilitate human hand for interacting computer with better performance.
