My suggestion is based on Psychomotor interaction particularly finer motor control of the upper limbs. The ability for the to hand to interact with UI dimishes with in older age. UI should be designed to create positive user esperience., this will motivate them to use systems we create and design. A
UI that uses smart technologies to reduces multiple touches and touchscreen that response appropriately to user input selection help the elderly access eHealth, telehealth and telemedicine at the comfort at their home. B
The hand is a tool in interacting with hand held devices, such devices should be design UI that facilitate the power grip and pinch grip, this will ease the difficulty associated with holding the device during interaction C
The elderly have both sensory and motor problems, Mechanical keyboard that are highly tactile with each key containing a separate spring and switch is user friendlier to the elderly,it is comfortable and yield less errors in data entry D
Display is the interface at which device is perceived, design and function of display will directly contribute to the user experience, , the mouse features trackball designed to suit easy grip is easier for senoirs
