User Research And Design Of Mobile Phone For The Old

The silver market or the elderly market gains focuses because of the rapid aging all over the world. The degree of aging in China is serious, and it becomes the world's most populous country in the elderly. The rapid development of communication and mobile technology allows mobile phone to become the elderly' indispensable tool in daily life. In this paper, mobile phone is developed to meet the characteristics and need of the elderly, using the UCD (User-Centered-Design) methodology.In the study, user research is to access user need at first. It includes analyzing the users and need to get the elderly' need about the mobile phone in daily life. This paper focuses the use experience, the expectation of all aspects, uses the interview, questionnaire survey to get data and creates personas by personas and scenario.Then the model is to be made, including the user model and the system model. The user model is made of the user mental model and the user task model. The user mental model consists of user characters, user goals and so on. The user task model is described by use case. When creating the system model, the system structure should be made.When completing the model, the prototype is made to evaluate, redesign, user test and redesign. The prototypes are the Low Fidelity Prototype and the High Fidelity Prototype.In the end, this paper includes making the system realize. It probes to describe the environment and process of the system.This study makes research on the elderly' mobile phone, including the following aspects: Firstly, considering the sensory experience of the elderly in vision, audition, and tactility, the design should confirm to the elderly' cognition. Secondly, the design enhances the use experience, and helps operation easier in the interactive process. Thirdly, the design develops practical functions, such as, Emergency Help, Information, Radio and The Caller Photo.
