Abstract
An aid for a blind person (1), includes a distance sensor (3), which creates a distance image of an object (2). The distance information that is generated by the distance sensor (3) is transmitted to a tactile matrix (10), which is integrated into a guide stick (11). The blind person (1) obtains information about his or her environment by touching the tactile matrix (10).
Claims17
A device for communicating environmental information to a visually impaired person, said device comprising:
- an information transmitter comprising a distance sensor integrated into an item of headgear which can be attached to a body of the visually impaired person;
- and
- a playback device which converts information supplied by the information transmitter into signals which can be perceived by the visually impaired person, the playback device being a portable feeler device integrated into a guide cane and the portable feeler device reproduces distance information supplied by the distance sensor by way of height profiles.
A device for communicating environmental information to a visually impaired person, said device comprising:
- an information transmitter comprising a distance sensor having a linear visual field which can be attached to a body of the visually impaired person;
- and
- a playback device which converts information supplied by the information transmitter into signals which can be perceived by the visually impaired person, and the playback device is a portable feeler device which reproduces distance information supplied by the distance sensor by way of height profiles, wherein
- the feeler device has a feeler surface which is embodied so as to correspond to a beam fan of the distance sensor and on which a distance profile of an object situated in the visual field is reproduced by means of a height step following a shape of the distance profile.
A device for communicating environmental information to a visually impaired person, said device comprising:
- an information transmitter comprising a distance sensor having a linear visual field which can be attached to a body of the visually impaired person, and the distance sensor has a visual field that is extended in terms of surface area;
- and
- a playback device which converts information supplied by the information transmitter into signals which can be perceived by the visually impaired person, and the playback device is a portable feeler device which reproduces distance information supplied by the distance sensor by way of height profiles, wherein
- the feeler device has a feeler surface embodied so as to correspond to a shape of the visual field, said feeler surface reproducing a distance image recorded by the distance sensor by means of a height profile corresponding to the distance image.
