Cognitive assistive technologies that aid people with dementia (such as Alzheimer's disease) hold the promise to provide such people with an increased level of independence. However, to realize this promise, such systems must account for the specific needs and preferences of individuals. We argue that this form of customization requires a sequential,(More)
This paper discusses the use of computer vision in pervasive healthcare systems, specifically in the design of a sensing agent for an intelligent environment that assists older adults with dementia during an activity of daily living. An overview of the techniques applied in this particular example is provided, along with results from preliminary trials(More)
Older adults with dementia often cannot remember how to complete activities of daily living and require a caregiver to aid them through the steps involved. The use of a computerized guidance system could potentially reduce the reliance on a caregiver. This paper examines the design and preliminary evaluation of a planning system that uses Markov decision(More)
perform routine activities: They cannot remember the proper sequence of steps or how to use the necessary tools. Strategies commonly used by caregiv-ers involve continually providing reminders or cues. Family caregivers find assisting their loved ones to be particularly upsetting and embarrassing, as it necessitates invasion of privacy and role reversal.(More)
BACKGROUND Demands on long-term-care facilities are predicted to increase at an unprecedented rate as the baby boomer generation reaches retirement age. Aging-in-place (i.e. aging at home) is the desire of most seniors and is also a good option to reduce the burden on an over-stretched long-term-care system. Personal Emergency Response Systems (PERSs) help(More)
BACKGROUND It has been shown that intense training can significantly improve post-stroke upper-limb functionality. However, opportunities for stroke survivors to practice rehabilitation exercises can be limited because of the finite availability of therapists and equipment. This paper presents a haptic-enabled exercise platform intended to assist therapists(More)
We investigate technological solutions for arts therapists who work with older adults with cognitive disabilities, such as Alzheimer's disease. We present ethnographic analysis of a survey of arts therapists in the UK and Canada, and show how there is a need for devices that can be used to promote autonomy and independence through engagement with creative(More)
This chapter is about the application of behaviour monitoring technology in the context of a smart home for people with dementia. It is not about the design of technology, but about the application and configuration of existing technology in a specific context: in this case, smart flats for people with dementia in London and Bristol. Technology was(More)
Long-term care (LTC) residents with cognitive impairments are often not permitted to use powered wheelchairs due to safety concerns, which results in a loss of mobility and independence. The authors have developed two prototypes of an anti-collision system for a powered wheelchair; one employs a 3D infrared sensor while the other uses stereovision. Both(More)
