Research On Human-Computer Interface Design Of Mobile Communication Terminal For The Aged

This paper stems from the project of National High Technology Research and Development Program of China, named "Research Faced to Computer Aided Definition Design about Product Innovation" (No.2002AA411110) and the Shaanxi Social Fund Project, named "Research on the Development of Shaanxi' Culture Information Enterprise".The paper introduces the development of mobile communication terminal and the diverse consumers' demands for it, analyzes the human-computer interface of current mobile communication terminals and the physiological as well as psychological features about the aged, and then sums up the features' effects which will influent the design of human-computer interface. Based on cognitive psychology, ergonomics, art design and match theories, the paper puts forward the aged-centered design methods about the human-computer interface of mobile communication terminal, including design steps such as user subdivision, experienced design, establishment of user description model, the matching of conceptual design model and user model, and user validation. Then the paper concludes the general design principles, such as security, usability, convenience and comfortableness, as well as the specific design principles faced to hardware interface and software interface. In the end, a mobile phone human-computer interface of advanced old person is designed as an example to validate the design methods and the principles.The paper provides the systematic methods and principles, which help designers to design the human-computer interface of mobile communication terminal for the aged, fills up the blank of design and research in this aspect, and embodies the ideas of human nature design and the concern for the aged.
