摘要： A porous sheet of elastic material supports an array of electrodes adapted to contact the wearer''s skin. The sheet and electrodes are conformed to the wearer''s body configuration by an outer less flexible sheath, interposed resilient material, and adjustable fastening means. The several electrodes are connected to a cable fed with electrical pulses adapted to produce a twodimensional electrical skin stimulation pattern representing or depicting a visible object.

摘要： A multiple anode photomultiplying image tube is provided employing an image intensifier structure and an array of anodes for converting visible information into patterned electrical signals. A modulating source associated with the tube assures that the electrical signals exhibit particular characteristics; and such signals are conveyed to an array of electrodes in contact with the skin of a subject, to be perceived by the subject as a conceptual image. The photomultiplying image tube can be mounted in or on spectacles, or on the head of the subject. Arrangements are disclosed for providing black and white information, color information, and stereoscopic information to the subject, and for using the eyes to aim the system at any desired object.

摘要： A tactile image converter for blind subjects comprises a television camera device the output of which modulates a commutating cathode-ray tube comprising a conductor array sealed in one face thereof. The camera device and commutating tube are scanned in synchronism with one another at a rate producing current pulses in the conductor array having pulse widths preferably in the order of 10 to 100 microseconds. The conductors of the array are coupled respectively to electrodes in contact with the subject''s skin to produce a two-dimensional electrical skin stimulation pattern of a visible object.
