Smart TV interface design and evaluation based on goal-oriented

The demand of people for television is higher than before, in the hope that the television becomes more intelligent. This requires that TV not only has reasonable functions and can be induced to the user's intention, actively to finish the task. But the existing problem is the interaction obstacle between the Interface on the TV, the people and the remote control, it is hard to get through the precise control of TV remote control. The study is to design the smart TV and its core is requirement goals, breaking the limitations that simply research from the software interface in the past. Design, first of all, from the user and television entry "remote control", in the form of user goals to define the hardware interface. Secondly, the hardware design is to guide the software design, and to keep good cooperation throughout the design process. Finally, study aims to assess the rationality of the design of hardware and software through the user goals. Research result sums up the three goals of TV interface design: function target, usability, user experience goals. Through designing and evaluating object, we put forward design principles and mode of intelligent TV interface.
