Abstract

People eat every day and biting is one of the most fundamental and natural actions that they perform on a daily basis. Existing work has explored tooth click location and jaw movement as input techniques, however clenching has the potential to add control to this input channel. We propose clench interaction that leverages clenching as an actively controlled physiological signal that can facilitate interactions. We conducted a user study to investigate users' ability to control their clench force. We found that users can easily discriminate three force levels, and that they can quickly confirm actions by unclenching (quick release). We developed a design space for clench interaction based on the results and investigated the usability of the clench interface. Participants preferred the clench over baselines and indicated a willingness to use clench-based interactions. This novel technique can provide an additional input method in cases where users' eyes or hands are busy, augment immersive experiences such as virtual/augmented reality, and assist individuals with disabilities.
握紧界面:新颖的咬合输入技术
人们每天都在吃东西,咬是他们每天最基本、最自然的行为之一。现有的工作已经探索了牙齿点击位置和下颌运动作为输入技术,然而握紧有可能增加对这个输入通道的控制。我们提出握拳互动,利用握拳作为一个主动控制的生理信号,可以促进互动。我们进行了一项用户研究,调查用户控制握紧力的能力。我们发现用户可以很容易地区分三个力度级别,并且他们可以通过松开(快速释放)来快速确认动作。在此基础上,我们开发了一个握拳交互的设计空间,并对握拳界面的可用性进行了研究。参与者更喜欢握紧而不是基线,并表示愿意使用基于握紧的互动。这种新颖的技术可以在用户的眼睛或手很忙的情况下提供一种额外的输入法,增强虚拟/增强现实等沉浸式体验,并帮助残疾人。
