| Summary: | 碩士 === 國立臺北科技大學 === 互動媒體設計研究所 === 102 === With the application of rapid development of digital technology and multimedia technology, the applications and functions of traditional TV is increasing. Information communication is transformed from one-way receiving into two-way exchange, through the integration of state-of-the-art hardware and software. This allows TV to be implemented with network capabilities and independent operating system, which is known as “Smart TV”. However, the market research organization NPD surveyed on December of 2012 indicated that only less than 15% of smart TV users could use new TV functions such as downloading applications or browsing websites. Many smart TV consumers indicats that current problem is mainly arising from inconvenient remote control. Therefore, this study aims to use experimental observation, performance and subjective measurements to investigate the usability of traditional remote control, motion sensing (or remote point) control and touch control, and finally to provide suggestions for smart TV remote control and interface design.
The main findings of this study are as blow. Statistically significant differences of the operating modes between three different remote control types are found. For traditional TV features, traditional remote control performs better than the others. For new smart TV features, motion control''s performance is better than the others. Overall, the usability of three types of remote controls are not rated only at “OK” level.
The results also provide smart TV remote control design recommendations as follows: (1) Intuitive and simple operations. (2) Avoid using composite keys/buttons. (3) Grouping buttons according to different functions/scenario. (4) Clear and recognizable icon design and words marked. (5) Provide one-hand control mode to reduce physical loadings. (6) No need to look down at the remote control. (7) Universal concerns at all ages.
