Thanks to their conversational capabilities, smart speaker-based voice assistants are gaining attention for their potential to support the aging population, though the empirical evidence is still scarce. This paper aims to obtain empirical evidence on older adults' experiences with a voice assistant. We especially focused on how their perception and use change over time as they progress from novice to more experienced users through a longitudinal field deployment study. We deployed Google Home devices in the homes of twelve older adults aged 65 and above and studied their use for sixteen weeks. Results show that the benefits our participants perceived have incrementally changed from enjoying simplicity and convenience of operation in the early phase of the study to not worrying about making mistakes and building digital companionship as they got used to using it. Results also show that participants confronted several challenges that evolved from the unfamiliarity with a voice assistant in their first interactions to coping with the functional errors due to limited speech technology as they got used to using it. Based on the results, we discuss design implications that could foster better user experiences with a voice assistant among older adults.

探索老年人对基于智能扬声器的语音助手的感知和使用:纵向研究

由于其对话能力,基于智能扬声器的语音助手因其支持老龄化人口的潜力而受到关注,尽管经验证据仍然很少。本文旨在获得有关老年人使用语音助手的经验的经验证据。我们特别关注他们的感知和使用如何随着时间的推移而发生变化,因为他们通过纵向现场部署研究从新手到更有经验的用户。我们在 12 名 65 岁及以上的老年人的家中部署了 Google Home 设备,并对其使用进行了 16 周的研究。结果表明,我们的参与者所感受到的好处已经从在研究的早期阶段享受操作的简单性和便利性逐渐转变为在习惯使用时不再担心犯错和建立数字伙伴关系。结果还表明,参与者面临着一些挑战,从他们第一次互动时不熟悉语音助手,到在他们习惯使用语音技术时应对由于语音技术有限而导致的功能性错误。基于这些结果,我们讨论了设计含义,可以通过语音助手在老年人中培养更好的用户体验。结果还表明,参与者面临着一些挑战,从他们第一次互动时不熟悉语音助手,到在他们习惯使用语音技术时应对由于语音技术有限而导致的功能性错误。基于这些结果,我们讨论了设计含义,可以通过语音助手在老年人中培养更好的用户体验。结果还表明,参与者面临着一些挑战,从他们第一次互动时不熟悉语音助手,到在他们习惯使用语音技术时应对由于语音技术有限而导致的功能性错误。基于这些结果,我们讨论了设计含义,可以通过语音助手在老年人中培养更好的用户体验。
