摘要

許多現有觸控式產品操作模式是由設計師主觀認知所設定，本研究欲了解現有操作模式與使用者直覺操作方式是否有等同性，發現真正直覺操作手勢為何，並比較其中差異性。
本研究將實驗分為模擬操作實驗及驗證實驗兩部份。模擬操作實驗以三種不同尺寸模擬多點觸控螢幕，針對受測者執行：選擇物件、執行物件、移動物件、捲動畫面、換頁、物件任意及等比縮放、物件任意及等比旋轉、輸入等八種任務上，觀察使用者直覺操作手勢及模式。驗證實驗則以可互動真實螢幕做進一步的實驗操作驗證。研究終以時間差、錯誤率及手勢操作型態為評估效標。實驗結果以ANOVA單因子多變量、交叉比對、描述性統計與事後檢定LSD進行統計分析。在主觀評量方面以SUS及NASA進行分析。
在模擬操作實驗與驗證實驗均顯示，多數人使用小尺寸觸控螢幕多使用直式操作，中大尺寸則多以橫式操作為主。在操作任務方面，物件縮放及旋轉任務中多點觸控或多種手勢類型情況出現比例明顯增加。螢幕尺寸與手勢間皆有顯著差異，隨著尺寸增加，多點觸控比例也隨之增加。平放模式使用多點的比例同時也更多於手持模式。

At present, the operation mode of many touch panel products are designed according to the designers subjective perception. This study seeks to find whether or not current operation modes are intuitive operation modes, to discover the true intuitive gestures for operating touch panels and compare differences.
This study divides the experiment into two parts: simulated operation and verification. The simulated operation experiment asks subjects to operate multi-touch panels of three different sizes, and complete eight tasks: select object, execute object, move object, scroll up and down, change pages, freely and proportionally enlarge/reduce object, and rotate object, observing the intuitive gestures for each operation. The verification experiment uses a real interactive panel to verify operations. The study then uses time difference, error rate and gesture operation mode as indicators for evaluating effectiveness. Experiment results were analyzed using one-way ANOVA, cross matching, descriptive statistics, and LSD; for subjective evaluation, SUS and NASA were used for analysis.
The simulated operation and verification experiments both show that most subjects operated the small touch panel vertically and the middle and large touch panels horizontally. In operation tasks, multi-touch and variation in gestures significantly increased for the tasks: enlarge/reduce object and rotate object. Significant difference existed between panel size and gestures, larger panels resulted in higher multi-touch ratio. The ratio of multi-touch increased when panels were fixed compared with when handheld.
