摘要

目前,全球约有3600万人受到阿尔茨海默病或相关痴呆的影响。在无法治愈的情况下,认知刺激等减缓恶化速度的非药物干预措施可使痴呆症患者及其护理人员受益。这些干预措施已被证明可以改善幸福感,减缓认知能力下降的速度。研究进一步表明,与电脑互动时的认知刺激与与人互动时一样有效。然而,操作电脑的需要对老年人来说往往是一个困难,并且阻碍了电脑的广泛采用。解决这一障碍的一个可能方法是提供一种自然语言界面,让痴呆症患者与认知刺激软件互动,就像他们与人类护理人员互动一样。这使得无论用户的技术水平如何,都可以使用辅助技术,并提供完全直观的用户体验。本文描述了一项初步研究,该研究评估了通过口头自然语言界面进行基于计算机的认知刺激的可行性。原型软件对23名用户进行了评估,其中包括健康的老年人和痴呆症患者。反馈非常积极。

A natural language-based presentation of cognitive stimulation to people with dementia in assistive technology: A pilot study
ABSTRACT Currently, an estimated 36 million people worldwide are affected by Alzheimer’s disease or related dementias. In the absence of a cure, non-pharmacological interventions, such as cognitive stimulation, which slow down the rate of deterioration can benefit people with dementia and their caregivers. Such interventions have shown to improve well-being and slow down the rate of cognitive decline. It has further been shown that cognitive stimulation in interaction with a computer is as effective as with a human. However, the need to operate a computer often represents a difficulty for the elderly and stands in the way of widespread adoption. A possible solution to this obstacle is to provide a spoken natural language interface that allows people with dementia to interact with the cognitive stimulation software in the same way as they would interact with a human caregiver. This makes the assistive technology accessible to users regardless of their technical skills and provides a fully intuitive user experience. This article describes a pilot study that evaluated the feasibility of computer-based cognitive stimulation through a spoken natural language interface. Prototype software was evaluated with 23 users, including healthy elderly people and people with dementia. Feedback was overwhelmingly positive.
