Abstract

Personal-assistant devices like Amazon Alexa and Google Assistant are increasingly popular among consumers. Users activate these systems through some type of wake-up approach, e.g. using a wake-word “Alexa” or “Ok, Google.” Voice-based interaction poses accessibility barriers for Deaf and Hard of Hearing (DHH) users, and technologies for sign-language recognition are improving. We therefore explore wake-up interactions for DHH users for potential personal assistant devices that understand sign language commands. Interviews with DHH users (N=21) motivated the design of six wake-up approaches, and we produced video prototypes demonstrating each using a Wizard-of-Oz approach. These prototypes were evaluated in a follow-up study in which DHH users (N=12) identified factors that influenced their preference among approaches. This study contributes empirical knowledge about DHH ASL signers’ preferences and concerns with wake-up interaction, thereby providing guidance for future designers of these systems.

聋人与个人助理设备手语交互中唤醒方式的偏好
像亚马逊Alexa和谷歌助手这样的个人助理设备在消费者中越来越受欢迎。用户通过某种唤醒方式激活这些系统,例如使用唤醒词“Alexa”或“Ok, Google”。基于语音的交互为聋人和重听人(DHH)用户带来了无障碍障碍,手语识别技术正在改进。因此,我们为DHH用户探索能够理解手语命令的潜在个人助理设备的唤醒交互。与DHH用户(N=21)的访谈激发了六种唤醒方法的设计,我们制作了视频原型,使用Wizard-of-Oz方法演示每种唤醒方法。这些原型在一项后续研究中进行了评估,在该研究中,DHH用户(N=12)确定了影响他们对方法偏好的因素。本研究提供了关于DHH手语使用者对唤醒交互的偏好和关注的实证知识,从而为这些系统的未来设计者提供指导。
