以自然吹氣作為人機互動介面的研究

Abstract

手機、平板電腦等智慧型裝置的出現為我們帶來了許多便利,降低了人與人之間溝通的障礙,並且讓資訊取得更加容易。以目前主流的互動方式而言,使用者主要都是透過觸控介面來與這些智慧化的行動裝置進行互動。但也由於裝置本身互動方式的侷限,使用者在特定雙手被佔用的情境下,如手 物、撐傘、搭乘大眾交通工具、騎腳踏車等等,往往無法輕易地透過觸控操作來滿足取得資訊的需求。另外,對部分的肢體殘障人士而言使用這些智慧型裝置同樣是十分困難而幾乎無法達成的任務。因此在這篇研究中我們將介紹一種新穎的人機互動技術——Blowatch。透過吹氣作為 使用者輸入方式的另外一種可能性,為特定使用情境與有特殊需求的使用者 供免手持互動 (Hands-free interaction)。我們將展示 Blowatch 所支持的互動技術範例,以及相關的應用方 向,並且 出以吹氣為出發點的互動設計準則與介面規範。

The emergence of smart devices promises to further enhance convenience to common communication and information retrieval tasks. However, there are some scenarios when users have trouble operating touch screens, such as, carrying a weighted bag or riding a bike. We introduce Blowatch, a novel input method for wrist-wearable devices and potentially for other mobile devices, which provides hands-free interaction to solve the scenarios that our hands are already busy. Users blow air on the wrist-wearable device to invoke several operations, such as, adjusting music volume, taking pictures or answering calls. In this paper, we explore the input dimension of the blow-based gesture set and examine the potential use of the blow-based gestures in a user study. To illustrate the potential of our approach, we developed a set of example applications for blow-based gestures and craft our proof-of-concept prototype. Finally, we compared the social acceptance between common hands-free interactions and our research.
