Interaction Design And Evaluation Of Blind Mobile Phone

The field of HCI (human computer interaction) has developed for about 20 years, and with the continuous emergence of new technologies, it has expanded to be a rising subject, interaction design. Interaction design means the design of interactive product that support our life and work. Interaction design is a creteria of designing, including many good guidelines and mothods for practice. Interaction design is a interdiscipline concerned with soft engineering, artificial intelligence, ergonomics, computer languages, cognitive science, social psychology, etc. Interaction design has been applied to a very broad area, including industry design, human-computer interaction design, and itself has been a important busness. Network consultant, rising companies, and the mobile computing industry have come to realize that it is interaction design that take the key role in the success of a new interactive product.Recently, the auditory display technology is rising which use the non-speech sound to express data , and will make the human-comluter interaction more natural. The blind mobile phone is designed for the blind peolpe, and also can be used by sighted people in some special occasion, with the autitory display technology. The article introduce the process of design and evaluation of the blind mobile phone with the interaction design creteria, firstly analyse the user's need, bring forward two input modes and two output modes, and make up prototypes; secondly make evaluation to evaluate and compare the input and output modes, inprove the prototypes according to the feedback and result of evaluaion; at last, make evaluation again ,and summarize the betterment.
