Senior-Specific Factors Guide: Motion Perception

by Max Baumgarten January 1, 2010

Relative to the rest of the population at large, seniors have reduced motion perception. Research on senior citizens and motion perception have found that compromised perception of motion negatively effects an ability to drive. Because seniors are less likely to detect collisions before they happen, they are more prone to unfortunate accidents.

Senior Friendly Design Guide: Motion Perception

by Max Baumgarten December 30, 2009

This one is a toughie: there is no obvious remedy for designers to help seniors with limited motion perception. Designers could try to stress movements and motions; for example, with an elder friendly computer, the movement of the mouse would be bold, pronounced, and easily detectable. Yet, not all objects can be amended in this [...]

Senior-Specific Factors Guide: Useful Field of View

by Max Baumgarten December 22, 2009

Research tells that that seniors have a limited Useful Field of View (UFOV), meaning they can’t see as much as younger adults or children. Because there are limits to what older adults can and can’t see, especially on the road, elderly drivers are relatively prone to get into car accidents.

Senior-Specific Factors Guide: Contrast Detection

by Max Baumgarten December 21, 2009

Poor visual acuity, which is common amongst seniors, reduces contrast detection sensitivity. So, the ability to detect contrast naturally declines with age. Reduced contrast sensitivity is also due the scattering of light as it enters the eyes, making it harder for the eye to detect distinctions. This is especially the case for the elderly.
