A button that allows the function of each key to be read out to the user, as well as the content of the display, menus, etc. will help persons with visual impairments.
Visual displays should show large characters with high contrast. Screens that reduce reflective glare are helpful.
Volume control is particularly helpful for persons with hearing loss.
Keys that are easy to feel and with a reasonable distance between the keys will help persons with visual impairments. Function keys should have different shapes.
Easy to grip body is important to persons with weak grip or poor manual dexterity. A telephone that remains stable when placed on a table can be advantageous.
