Research on the human-computer interaction mode designed for elderly users

The research on human-computer Interaction (HCI) mode is mainly to improve the quality of interaction between user and computer. Due to differences in many aspects, such as physiology, experience and ability, most current interactive systems cannot meet the needs of elderly users. Based on existing theories and models, the paper combines the analysis results of sampling data, gives consideration to the characteristics of the special group-elderly people, verifies Fitts´ Law, obtains the interaction mode and designs principle that can meet its requirements, thus enabling more elderly users to achieve greater efficiency and satisfaction in the process of using computer.
