ABSTRACT
After we meet the needs of functional requirements, we should consider how to design excellent friendly man-machine interaction. The design of friendly man-machine interaction requires us to take the hardwares, using situations and users’ habits into consideration and reprocesses softwares according to users’ needs [3]. The most critical evaluation standards are whether it is able to use and whether it is easy to use. Due to the development of hardware industry, smartphones are usually equipped with various sensors. Any single sensor or combinations of sensors is able to give orders to smartphones. With the help of psychology, we are able to design friendlier man-machine interaction and improve users’ experience.
