移动的输入技术在执行其他任务时可能体积庞大、突兀或难以使用。在本文中，我们提出了Hambone，一个轻量级的，不显眼的系统，提供快速访问，微妙的，多任务的能力，基于手势的移动终端交互。Hambone使用两个小型压电传感器放置在手腕或脚踝上。当用户移动他的手或脚时，由移动产生的声音通过骨传导传播到Hambone。然后，Hambone将信号以数字方式传输到移动终端或计算机。使用隐马尔可夫模型（HMRM）识别信号，并将其映射到控制应用程序的一组命令。在本文中，我们提出了硬件和软件实现的Hambone，初步评估，并讨论未来的机会，在生物声学手势为基础的接口。
Mobile input technologies can be bulky, obtrusive, or difficult to use while performing other tasks. In this paper, we present Hambone, a lightweight, unobtrusive system that affords quick access, subtlety, and multitasking capabilities for gesture-based mobile device interaction. Hambone uses two small piezoelectric sensors placed on either the wrist or ankle. When a user moves his hands or feet, the sounds generated by the movement travel to Hambone via bone conduction. Hambone then transmits the signals digitally to a mobile device or computer. The signals are recognized using hidden Markov models (HMMs) and are mapped to a set of commands controlling an application. In this paper, we present the hardware and software implementation of Hambone, a preliminary evaluation, and a discussion of future opportunities in bio-acoustic gesture-based interfaces.
