An assistive grid that overlays the touch screen of a device such as a smart phone, tablet computer, or other intelligent device that allows blind or otherwise visually impaired users to easily locate and touch standard locations on the device's touch panel screen. A standardized user interface is presented by applications on the device, or on Internet websites accessed by the device, provides a standardized method of interacting with a multitude of applications and websites by the visually impaired or blind. Gestures that enhance usability of the interface by the blind are provided. Optionally, the assistive grid can incorporate raised indicia, such as Braille, on the grid surface to aid a blind user when learning how to use a given device. |
