In order to examine the effect of an avatar in natural interaction with elderly users in ambient intelligent environments, we performed an empirical study with elderly people (normal aging, mild cognitive impairment and Alzheimer's patients) not only on subjective but also on objective measures. The data supports the following: 1) The subjects followed some(More)
Cognitive training has been a growing field in recent years. It is established that training improves cognitive abilities in healthy elderly people. Specialized software and commercial devices including the possibility of cognitive gaming has been placed into the market; most of them are based on neuropsychological models of cognitive aging, but few have(More)
HERMES aims at alleviating the elderly decline in both declarative and prospective memory, based on a set of ambient daily support and cognitive training applications. Its applications comprise memory aids and cognitive training games, both of which are presented in the paper. The paper introduces also the motivation of the HERMES project and applications.(More)
BACKGROUND Research on non-pharmacological therapies (cognitive rehabilitation) in old age has been very limited, and most has not considered the effect of interventions of this type over extended periods of time. OBJECTIVE To investigate a new cognitive therapy in a randomized study with elderly people who did not suffer cognitive impairment. METHODS(More)

The program started in January 2009 as part of the Human Technology Centre, a newly established project house, funded by the Excellence Initiative of the German federal and state governments. The program aims at(More)
Alzheimer's disease (AD) is the most common dementing disorder and presents with a progressive and irreversible cognitive decline of gradual onset. To date, several reports have involved iron in AD physiopathology. In this study, we have analysed TFC2 variant and HFE mutations (H63D and C282Y) in 211 AD patients and 167 controls recruited from an area of(More)
The complexity of new information technologies (IT) may limit the access of elderly people to the information society, exacerbating what is known as “the digital divide,” as they appear to be too challenging for elderly citizens regardless of the integrity of their cognitive status. This study is an attempt to clarify how some cognitive functions (such as(More)
In this paper we describe the design, development and evaluation of user interfaces for a modern digital home based on the ISO/IEC 24752 standard: Universal Remote Console—URC. Two target groups were addressed: seniors aged 65 years and above and people suffering from Alzheimer's disease. Our goal is to design user interfaces (UI) for our target groups that(More)
