Filed:

Nov 12, 2003

Appl. No.:

10/706733

Inventors:

Steven Landau - New York NY, US

International Classification:

G01C 21/00
G08B 1/00

US Classification:

701211, 701300, 34053911

Abstract:

A system that provides a means for blind or visually impaired people to navigate through a complex environment using auditory cues. Two-way transceiver devices, held by the person, connect through a communications network to a computer system. The computer system activates appropriate auditory signals that are output from audio beacons located throughout the environment based on input provided through the transceiver. Additional interactivity can be incorporated into the system by means of the computer system.

G06F 9/00

US Classification:

341 27, 715702, 345173

Abstract:

A computer-based system permitting a visually impaired user to interact with tactile graphic-based interactive software applications is provided. The system includes a host computer having a data processor and a drive for running the interactive software applications and a pressure sensitive work pad. The work pad has X and Y pressure sensitive members disposed in a grid array for providing unique location output signals corresponding to each different location on the grid array. The work pad is operatively connected to the host computer and an overlay comprising a sheet is placed over an upper surface of the work pad. The overlay having a work space which bears tactile indicia which corresponds to a selected one of the interactive software applications and also includes a tactile graphical user interface (TGUI) formed thereon. The TGUI has a plurality of tactile control members which generate location output signals when pressed. These output signals are communicated to the computer which processes the signals as control signals directing the computer to perform an operation.

International Classification:

G06F 3/041

US Classification:

345173, 178 1803

Abstract:

Touch sensors and associated systems and methods are disclosed. The amount of skin of a user's finger that touches the touch sensor changes in relation to the intensity or pressure applied by the finger. A variable control signal is generated proportional to the pressure applied to the touch sensor.
