The Research And Application Of Interaction Design For Handheld Mobile Terminals

Handheld mobile terminal which is an important information carrier in information society has not only become a necessity of life, but also has completely changed the human lifestyle. Meantime, the mobile industry has brought a lot of benefits to social and economic development. Till the end of 2007, the global mobile phone penetration rate had reached 49%. The mobile phone market has been developed a lot but is not saturated at all. With the popularity of 3G technology, It has became the general trend that mobile terminals with a combination of the Internet. Therefore, many new types of handheld mobile terminal, such as MPC, MID, UMD etc., optimized for mobile Internet, has been introduced in recent years. We are entering an era of Mobile 2.0.While we are in high spirits at the prospects of mobile terminal market, the handheld mobile terminal development is faced with lots of challenges. The functionality increased is leading to ease of use reduced. What's more, the change of user groups results in that the companies is difficult to grasp users'needs. In addition, the market competition is intensified, which drives product development cycle to be shorten. Therefore, the key to develop a successful handheld mobile terminal is to grasp the users'needs accurately and enhance the user experience of the product. Now, the consumers would not only be satisfied the good-looking appearance of products, but pay more attention to the interaction with products, which is expected to provide them a wonderful experience. Firstly, The handheld mobile terminals have not only software graphic user interface but also hardware user interface. Secondly, the users of hand-held mobile terminals are always with mobility and easy to be interfered. As a result, the general theory interaction design, which is major in desktop computer application and web, should not be completely suitable for designing hand-held mobile terminals.In this study, the question about how to better apply interaction design to handheld mobile terminal development is discussed based on the general theory of interaction design, combined with research findings in the fields of product design, ergonomics, cognitive psychology and so on. Analyzed the handheld mobile terminal user interface from visual, tactile and auditory senses. Introduced theoretical framework to divide the visual user interface into three levels, which are frame level, symbol level and style level. Summarized the design principle and design & research methods for handheld mobile terminals. Finally, made use of an exercise to validate feasibility of the study result.
