Research And Design Of Usability Based Stream Media Video On Demand Of Mobile

In the development of computer network and embedded system technology, each kind of portable information terminal appearance has brought a huge change for people's work and the life style, and they have already become the essential item for people. Accordingly in this current, mobile video which is the new application service is flourishing and it will become the mainstream service in the domain of mobile information service. Being an important interaction application service, mobile video service which is based on stream media obtains more and more attention in its interaction design especially usability research. Users'needs of mobile information service interaction develops from the past function realization into highly needs of the user experience and usability now.The emphasis of the research and design in this paper is user information collection for user model construction, and usability evaluation of interaction for high fidelity UI design. Finally, the UI design has obtained a good usability. We adopt the iterative evaluation to obtain plentiful data which could be reference for next design, test and evaluation, and we get the final feedback to validate the validity and reliability of reference which from previous evaluation. In addition, the whole UI design at the end of paper validate the correctness of user model and interaction wire frame, and give a demonstration of design method and flow of mobile stream media video service which is based on usability.This paper contains user test, usability evaluation, UI design, wireless network connection technology, embedded system, and mobile video service and so on. Also it is good reference for other interactive personal mobile information terminal services which are based on usability.
