Looking for similarities in movement between and within homes using cluster analysis.

In this article we examine data from eight purpose-built aware homes over a six-month period, looking at presence in rooms to try to determine patterns among the older residents. We look for homes that have similar movement patterns using cluster analysis. We also examine how movement over days clusters within individual homes.

Objective real-time assessment of walking and turning in elderly adults.

Recent research suggests that falls are the most common cause of injury and disability in older persons. Invasive systems or body worn sensors can be employed in controlled clinical and laboratory settings to determine clinical measures of gait and stability. This study by contrast aims to explore how video technology, can be employed to unobtrusively determine the same measures.

A portable neurological monitor for use in cognitive function studies.

The Visual Evoked Potential (VEP) has long established itself as a useful diagnostic tool for clinical use. The VEP is typically recorded in clinical environments due to equipment and experimental set-up. An alternative is proposed in this paper, whereby a light-weight, portable neurological monitor using active dry-electrodes is proposed and VEP data compared against clinically recorded data.
