Designing for the Life Span Segment 3

Slide 67 Content

Summary Conclusions - Design Response to Sensory Change:

Appropriate control and display design requires "redundant" cueing in the presentation of information and the design of mechanisms allowing for successful and humane interface with technology and products;
Redundant cueing is backing up a signal to one sensory mode with another signal to a different sensory mode... as an example, pushing a button on a telephone that gives tactile feedback and a "beep" to the ear informing the phone user that actuation of the device is either partially or fully successful;
Differentiation of controls to convey different functions is also important - utilizing shape coding, tactile coding, size differentiation, organization and placement to separate functions - in order to provide successful use of product technologies to older adults;
Most changes made to products and technologies to accommodate age changes do not detract from use of products by younger age segments in the population... usually, the changes enable use for all.

Design responses to sensory change include and are not limited to...
