Natural ageing brings with it many physical and cognitive impairments in the elderly, which challenges them in independently performing their daily activities. Many assistive technologies such as alarms, mobile phones, and video conferencing are available to support the elderly and their caregivers. However, these technologies require constant interaction and attention. Augmented Reality (AR) can be used to remotely guide the elderly in their daily tasks. From all known techniques, projection-based AR is suitable for the elderly because the digital information can be displayed on any real surface or any object without interaction or holding the devices. This doctoral thesis focuses on developing solutions to remotely guide the elderly in their daily activities through a caregiver. We adopted the design science methodology to iteratively design, implement and evaluate these solutions. Two constructs were developed for navigation activities utilizing laser projection and four constructs were built for cooking activities using fixed projection. We evaluated each construct in terms of feasibility and usability with actual elderly people, some of them have some form of memory problem. The results demonstrate how remote collaboration systems can be developed to guide the elderly in daily activities through a caregiver. The existing devices can be equipped with projection-based AR technology and elderly are willing to use it. The findings also suggest that augmented reality could help design systems for other daily activities such as shopping, or cleaning dishes, in order to improve the autonomy, quality of life, safety and well-being of the elderly.
