Abstract

Electrical muscle stimulation (EMS) has been used successfully in HCI to generate force feedback and simple movements both in stationary and mobile settings. However, many natural limb movements require the coordinated actuation of multiple muscles. Off-the-shelf EMS devices are typically limited in their ability to generate fine-grained movements, because they only have a low number of channels and do not provide full control over the EMS parameters. More capable medical devices are not designed for mobile use or still have a lower number of channels and less control than is desirable for HCI research. In this paper we present the concept and a prototype of a 20-channel mobile EMS system that offers full control over the EMS parameters. We discuss the requirements of wearable multi-electrode EMS systems and present the design and technical evaluation of our prototype. We further outline several application scenarios and discuss safety and certification issues.

zap++:用于细粒度可穿戴力反馈的20通道电肌肉刺激系统

电肌肉刺激(EMS)已经成功地应用于HCI，在静止和移动环境中产生力反馈和简单运动。然而，许多自然的肢体运动需要多个肌肉的协调驱动。现成的EMS设备通常在生成细粒度移动的能力方面受到限制，因为它们只有少量的通道，并且不能提供对EMS参数的完全控制。功能更强大的医疗设备不是为移动使用而设计的，或者与HCI研究相比，通道数量和控制程度仍然较低。在本文中，我们提出了一个20通道移动EMS系统的概念和原型，该系统提供了对EMS参数的完全控制。讨论了可穿戴式多电极EMS系统的需求，并给出了原型系统的设计和技术评价。我们进一步概述了几个应用场景，并讨论了安全和认证问题。
