Research On Intelligent Television Interactive Model Based On Hierarchy Analysis And Task Analysis

With the rapid development of Internet era as well as the advent of tri-networks integration and the era of the internet of things,TV products is in the innovation era of transition to the intelligent terminal,many manufactures have introduced concept model of their own smart TV.It can be said like that the technology and equipment have been able to support mature product model, but the remote forms and HMI mode which matched with them are in a relatively primitive stage.The user experience did not get a higher improvement.This thesis investigated into the problem of Smart TV’s interaction model.Firstly,make the sampling ratio for the measured audience,then establish the functional unit model of the smart TV according to the results of the user survey, and calculus the operating system for it;Secondly,get the importance character of function unit and operating system with the AHP method of the weighting algorithm, and extract the component factors of remote control mode.Finally,define the gesture and input mode of the TV remote control model by using the way which combine the contextual inquiry method and task analysis method of user research theory with low-fidelity experience model, and obtain a set of concept guide of smart TV interactive model combined with advanced competitive analysis.The aim of this thesis is to research the development situation of the smart TV,build the mental model of the users,establish a set of design guide for future TV interaction model,and design a set of remote control system program as well as its compatible interface program according to the research conclusion.Make a summary of shortcomings and problems in research for this subject,and analyze the interactive technology which have a profound influence and will make a breakthrough in the future of the modern interaction model.
