碩士 === 國立臺北科技大學 === 互動媒體設計研究所 === 99 === With the development of multi-touch screen technology and related products, portable devices with high interaction provide users convenience in their daily life. However, these state-of-the-art human-computer systems, equipped with totally different interface from conventional systems, could raise more or various usability problems. Therefore, this study aims to understand the usability of interactive multi-touch control interface. This study started with investigating and selecting representative application "This is Note" and "Awesome Note" in the App Store of iPhone. A usability testing was then conducted to examine the selected interface to measure the performance and subjective opinion. This was to form the development of a new "Note" interface with good usability (assumed). Finally the new interface was also evaluated in terms of usability to identify the usability principle of interactive multi-touch interface. The results were analyzed using repeated measures to examine the significance between different interfaces in task completion time, errors and subjective ratings. The results show that new interface performs better than the existing ones, which identifies the value of usability suggestions obtained from the pilot study. This study makes the following conclusions. (i) The design of background and icons should be clearly distinguished; (ii) layout design should meet the intuition and meaning of hand gesture; (iii) the icon design and interaction mode should consider users'' previous experience; (iv) avoid the interference between different interface elements; (v) using finger anthropometric data to design the interface; (vi) reducing layer increases efficiency; (vii) Simple interface enhances user acceptance; (viii) optimization of keyboard design reduces errors; (ix) interface styling design affects user preference. It is expected that the results can be useful references for practical interface design and future research of multi-touch interface.
