A novel human-robot interaction system based on HMM

A novel human-machine interaction system based on hidden Markov model (HMM) is proposed to resolve human motion in this paper. Aiming at the complexity and exclusivity limitation of traditional robot Human Machine Interface (HMI), a kind of portable and universal device, such as smart phone, is chosen as the HMI. Smart phone´s internal accelerator and HMM are utilized to obtain people´s motion information and to transform the user intention to robot instructions. The latest 3G technology and advanced interaction method of smart phone are used to develop a friendly human-machine interaction system which is portable, universal, flexible and without limitation of distance. The experiment shows that the system introduced in this paper can realize a friendly, portable and universal robot control.
