智慧型手機在多裝置環境下的選取方式設計與探討

Abstract

本研究提出RealSense與SmartChoice兩種適用於不同情境的選取方式，以幫助使用者透過手機在多裝置環境中能更加容易的選擇到目標裝置。RealSense收集環境中所有手機的電子羅盤數值以計算使用者之間的相對方向。而SmartChoice透過手機不停發送紅外線以偵測使用者所要選擇的目標 現今智慧型裝置蓬勃發展，不只是智慧型手機，智慧電視、冷氣等智慧家庭家電也越來越普及。使用者除了直接操作這些裝置，還能夠透過自己隨身的手機或平板來與這些裝置互動。但是當環境中有多台裝置時，使用者要從中選擇所要操作的裝置是一件麻煩的事。目前普遍的方式，使用者必須從所有裝置中的清單中透過裝置的名稱找出目標，而常常無法將裝置名稱與裝置本身連結在一起，而造成選取上的困擾。我們將RealSense與傳統選單、圓餅選單以及NFC作比較，並且將SmartChoice與傳統選單、室內地圖、相機與丟擲等方式比較。實驗結果顯示RealSense是最容易使用且直覺的，尤其是在使用者互相不熟稔的情境下。而SmartChoice雖然因為需要對準才能操作，因此有較長的操作時間，但是SmartChoice在容易使用與直覺性上也都獲得最高分，而且在裝置數量在4台以上時都是使用者最喜歡的操作方式。

We present RealSense and SmartChoice, technologies that enable users to easily select the target device in multi-device environment with smartphone. RealSense continuously collects the directional heading of each phone to calculate the virtual position of each user. SmartChoice continuously sends infrared signal to all devices in the environment to detect the target device. The number of smartdevice is increasing, including smartphone, smartTV, and so on. User can control these smartdevices directly or using their mobile devices to interact with them. In the interaction between these devices, users need to select the target from the traditional linear menu to establish the connection. When there are more items in the menu, it will be much more difficult to select the right target. User has to search the target’s name from the list of all devices. And they can’t associate the name with device easily. This work focused on user prefers of selecting device in multi-device environment. We compared RealSense with linear menu, pie menu and NFC, and compared SmartChoice with linear menu, indoor map, camera and throwing. Our results show that participants preferred RealSense than other sharing interactions especially they were unacquainted with each other. For SmartChoice, although pointing took more time because of the requirement to point precisely within a range, it got the highest scores on usability and intuition.
