“…Cushman et al in [36] also present a comparative study between a navigation system on VEs and the real world while evaluating Alzheimer's participants navigation aptitudes and proving the ecological validity of VR environments. Parson et al work in [14] analyse the appropriate way to create neurocognitive interfaces in VEs.…”

Alzheimer's screening tests are commonly used by doctors to diagnose the patient's condition and stage as early as possible. Most of these tests are based on pen-paper interaction and do not embrace the advantages provided by new technologies. This paper proposes novel Alzheimer's screening tests based on virtual environments and game principles using new immersive technologies combined with advanced Human Computer Interaction (HCI) systems. These new tests are focused on the immersion of the patient in a virtual room, in order to mislead and deceive the patient's mind. In addition, we propose two novel variations of Turing Test proposed by Alan Turing as a method to detect dementia. As a result, four tests are introduced demonstrating the wide range of screening mechanisms that could be designed using virtual environments and game concepts. The proposed tests are focused on the evaluation of memory loss related to common objects, recent conversations and events; the diagnosis of problems in expressing and understanding language; the ability to recognise abnormalities; and to differentiate between virtual worlds and reality, or humans and machines.The proposed screening tests were evaluated and tested using both patients and healthy adults in a comparative study with state-of-the-art Alzheimer's screening tests. The results show the capacity of the new tests to distinguish healthy people from Alzheimer's patients.

Although virtual reality (VR) technology has been implemented as a tool to address the health issues of older adults, its applicability to social connectedness is underrepresented in the literature, and less is known about its efficacy in this area in contributing to overall wellness and well-being in later life. Expanding the VR possibilities beyond traditional entertainment purposes holds considerable potential for the older adult market. Technological tools have been employed in the elder health care field for many years, and cutting-edge developments such as virtual and augmented reality have begun to be used to facilitate optimal wellness in aging. Such technological advances have the potential to significantly impact one of the most important issues that older people face: social isolation and loneliness. This paper will serve as an introductory exploration of what is currently known about the use of virtual reality technology with an older cohort.

“…The decline in visuo-spatial working memory with aging could be linked to a reduced ability to inhibit irrelevant information that uses up some of the working-memory resources 1 needed to learn complex new routes (Mammarella et al, 2009). Difficulty learning new routes and disorientation are greater and more prevalent in patients suffering from mild cognitive impairment (Cushman et al, 2008;Hort et al, 2007) or Alzheimer's disease (Liu et al, 1991;Rainville et al, 2001;Zakzanis et al, 2009). …”

a b s t r a c tAlthough old people make up an extremely vulnerable road-user group, older pedestrians' difficulties have been studied less extensively than those of older drivers, and more knowledge of this issue is still required. The present paper reviews current knowledge of older-adult problems with the main components of pedestrian activity, i.e., walking and obstacle negotiation, wayfinding, and road crossing. Compared to younger ones, old pedestrians exhibit declining walking skills, with a walking speed decrease, less stable balance, less efficient wayfinding strategies, and a greater number of unsafe road crossing behaviors. These difficulties are linked to age-related changes in sensorial, cognitive, physical, and self-perception abilities. It is now known that visual impairment, physical frailty, and attention deficits have a major negative impact on older pedestrians' safety and mobility, whereas the roles of self-evaluation and self-regulation are still poorly understood. All these elements must be taken into consideration, not only in developing effective safety interventions targeting older pedestrians, but also in designing roads and cars. Recent initiatives are presented here and some recommendations are proposed.
