Development of an Attention Function Evaluation System Using Image Processing to Reach Targets

Abstract

We develop a system (attention function evaluation system) to evaluate attention function by reaching targets using image processing. The attention function evaluation system does not use devices such as controllers, but uses an interface (spatial switch) that draws the targets on an image captured by a camera and judges contact when the subject blocks the target. To verify the effectiveness of the attention function evaluation system, we will conduct a comparative experiment with conventional testing methods on elderly people with MCI (Mild Cognitive Impairment) and with mild to moderate general cognitive decline. As a result of the experiment, by using the attention function assessment system, we were able to measure the direction of attention and the time required for the reaching movement due to spatial switching, which could not be obtained using the conventional method, and we were also able to confirm the relationship between attention function and cognitive function.
