Those suffering from mild dementia exhibit impairments of memory, thought and reasoning. It has been recognised that the deployment of technological solutions to address such impairments may have a major positive impact on quality of life. In the current paper we present results from the CogKnow Project following the evaluation of a suite of mobile and home based cognitive prosthetics to assist persons suffering from mild dementia. The results following an evaluation of the technology conducted with 16 people with mild dementia (and their carers) across 3 different trial sites are outlined. The paper concludes with details describing the process by which the outcomes of the evaluation will be used to guide the developments of a second generation of both mobile and home based cognitive prosthetic.
