Abstract
A display device which displays image information in a form perceivable by a blind person. For this purpose, the display device has a plurality of areally arranged elements (1), which are individually actuatable, and an actuation device for actuation of the elements (1), whereby through the elements (1), electronic image information (7) fed into the evaluation device (16) is tangibly represented through the elements (1). The actuator elements may be arranged areally on a flexible substrate (13), which are individually actuatable, whereby through the actuator elements (11), vibrations and/or heat and/or electrical impulses can be generated.
Claims27
A display device comprising:
- a plurality of elements arranged on a surface area of a support, said elements being individually actuatable to generate on said surface area a representation of an image defined by input electronic image information, said representation of said image being adapted to be detected from said elements by touch, and said elements also being individually operable to generate an output in response to mechanical touching of said elements;
- an actuation device configured to receive the input electronic image information and to actuate said elements to generate the representation of the image defined by the input electronic image information that is detectable by touch;
- and
- an evaluation device for evaluating the output generated by said elements in response to mechanical touching of said elements, said evaluation device converting said output into output electronic image information defining an image generated by said mechanical touching.
