    Abstract: 現今智慧型手機多採用直覺操控的多指觸控操作方式 (Multi-touch)為使用者 介面，此一介面主要設計為便於食指或多指操控的輸入方法，然而生活中有許多 時機會選擇使用單手操作手機（例如行走或提物時），由於單手操作的限制產生手 機使用上的不便。第一個主要問題為觸及區域問題（Reach Problem），2012年開始， 手機螢幕尺寸不斷增大，隨著手機尺寸越來越大，單手持握手機時無法觸及到之 範圍也增加，國外雖有幾項針對單手操作的研究，但其研究的手機尺寸乃基於 3.5” 左右的大小，未能有效支援 4”以上的手持裝置。第二個主要問題為多指手勢無法 操作之問題，過去研究已發展部分單指操作替代方案（thumb-based gestures）以及 利用感測器增加輸入模式（input modality）之應用。 本計劃擬研究 4”以上至 5.3”之間的智慧型手機或平板使用單手操作之方 式，探討利用拇指觸控能力及內建感測器資訊設計單手使用手持裝置之可能應 用，包含一、Fast Reach輔助工具，利用拇指舒適區操控無法觸及範圍之按鍵功能。 二、Fast Zoom/Rotate輔功工具，結合 Fast Reach或外加壓力感測模組來提供單手 縮放、旋轉之功能。本計劃研究成果將可運用在智慧型手機或小尺寸平板上，提 供使用者更自然且便捷的行動平台使用者介面 (Mobile User Interface)。
    Multi-touch technology has been adopted widely in mobile devices. These user interfaces mainly support index finger and multiple fingers to interact with the UI elements. However, people prefer to use one-handed input in many situations. In 2012, mobile devices come in a wide range of screen sizes. For example, an iPod Nano has a 1.5-inch multi-touch screen and Samsung Galaxy Note smartphone has a 5.3-inch screen. Devices with larger touch screens have more areas that are difficult to reach by thumb in one-handed use. To reach these areas, users need to change how they grip the device, which makes the device less stable and may also feel less comfortable. We called this problem a “Reach problem”. Furthermore, the thumb cannot perform multi-finger gestures such as Zoom in/out and Rotate, some researchers tried to develop thumb-based gestures or use build-in sensors to enhance the single-handed input modality. In this project, we plan to investigate single-handed input methods on 4”~5.3” mobile phones or tablets. We will combine thumb-based and sensor-based approaches to develop several potential interactions. The research topics include: (1) “Fast Reach”: a technique to accommodate quick access for screen targets relatively distant from the thumb’s interactive space. (2) “Fast Zoom/Rotate” extends Fast Reach to provide one-handed zoom and rotate by adding pressure sensors on the edge of mobile phones. The input techniques can support wide range of phone sizes and overcome the problems of one-handed use.
