| Research Abstract |
This is an experimental study with eye-camera to investigate visual perception in persons with dementia, while their walking in various settings for wayfinding. The followings are results and proposals based on the experiments.
1) The hall is more difficult than corridor in terms of wayfinding specially fordementia group, due to more complex visual noises. The Dementia group tends to have the narrowest range of eye fixations. Therefore, the dementia group has difficulties to search on appropriate visual cues. The dementia persons who unable to rearch their goal, tend to walk straight ahead to the other end, due to limitedand biased visual search. 2) Eye fixations on continuous stimuli of abstract signs in dementia group increase more those on non-continuous stimuli, and that eye fixations in cerebrovascular's type tend to be nore biased than those in Alzheimer's type to the floor and lower portions. We infer that it raises visual perception level for dementia group to arrange continuous visual stimuli as a wayfinding cue on floor portions.
