電視技術快速的發展，從黑白電視到彩色電視，從CRT螢幕到LCD螢幕，從類比電視到數位電視，電視的機體愈來愈輕薄，電視技術不斷的在進步，近年來，相關廠商更是發展了提供上網服務的互動式數位電視。
有鑑於目前對於數位電視上網的網頁顯示介面以及遙控裝置的設計尚未有一定的準則，所以本研究希望能夠利用人因工程的方法對電視上網的網頁設計提供建議還有設計出符合大眾電視上網需求的遙控裝置，希望能夠迎合電視史的發展趨勢。
本研究將分成兩個部分進行，第一部分實驗是網頁顯示介面的設計，找出網頁在電視上適宜觀看的字體和游標大小，並且在這階段找出在觀看電視時，觀看者可能使用的手勢控制方式；第二部分實驗是電視上網遙控裝置的設計，先以動作分析找出電視上網所需的操控功能，再對五種可使用於電視上網的遙控器裝置做可用性評估，並找出各裝置在操作電視上網時的優劣。
本研究在統整與分析實驗數據後對於電視上網在網頁顯示的字體和游標大小提供一個初始值的設計建議，而在操控部分對於電視上網的遙控器裝置提供設計建議，並且設計了一款概念式遙控器。

The display industry has grown so fast from black-and-white TV to color TV, from CRT monitor to Liquid Crystal Display, and from analog television to digital television, getting thinner and thinner. The display technology has made great progress, and its factories and stores further provide the interactive TV with Internet service.
There is no standard for website layout and design of remote control device to date, and thus this study aims at proposing evaluation and suggestion to website layout as well as designing a proper and satisfactory remote control device for Web TV through human factors methodology, thereby to meet the demand of television history.
In this study, the experiments were consisted of two parts: Experiment I and II. Experiment I paid much attention on website layout design for Web TV, investigating the proper sizes of characters and cursor as well as finding out possible gesture control motions. On the other hand, Experiment II focused on the design of remote control device, looking for the operating function for Web TV by means of motion analysis, usability evaluation and competitive advantage analysis for five different devices. After integrating analysis of all experimental data, we proposed a default value of the size of characters and cursor for the website layout design; besides, we provide suggestions for the design of remote control device and also design a new concept remote control device.
