Braille tactile matrix touch adds new dimension to object and voice recognition processing

Human Brain Visual and Voice Processing (Credit: MPI for Human Cognitive and Brain Sciences)New and most importantly free global positioning navigation and topographic mapping services are gaining popularity on the on mobile devices. Google (GOOG) and Garmin (GRMN) as well as other technology leaders are offering new flavors of the cloud computing GPS services available on the specialized GPS devices and the common use personal communicators, smartphones and tablets. As the international global positioning satellite services are include satellite constellations available from different countries, the GPS enabled personal communicators and specialized GPS navigational devices become more and more sophisticated. The researchers and scientists are working on the new methods in the area of voice and image recognition to create new and advanced user interfaces capable of utilization of the new services for mobile users and for specialized personal communicators providing fully enabled Google GPS navigational and topo mapping services for visually impaired and blind people.   

Braille tactile matrix

Different theories exist as to how the human brain recognizes familiar objects, and learn while absorbing shapes, contours and path ways while exploring the new and the unfamiliar objects within the three dimensional map of the terrain. For quite awhile it was assumed that voice recognition and objects recognition are two separate processes which are combined in the human brain on a higher processing level. For the visually impaired and blind people the sensoric information from the tips of the fingers is processed in a separate channel and join the other streams of information processing also on a higher levels. While working on the three dimensional soft Braille display active pin-matrix  topographic map which shapes the surface of the Braille interactive touchable display, which could also serve as the Braille pin-board, the NASA researchers introduced the prototype of the dielectric elastomer Electro Active Polymers, or EAP, which act as tiny muscles of the refreshable soft Braille display. New and improved prototypes of interactive personal communicators for visually impaired and blind people use Electro Active Polymers technology to allow sensitive skin receptors receive enough Braille formatted directional path of trail on the three dimensional topographic map formed by the Electro Active Polymers active matrix soft Braille display of personal communicator.

Most recent findings prove that voice and object recognition are closely related. The scientists of the Max Planck Research Group focused on Neural Mechanisms of Human Communication and Human Cognitive and Brain Sciences, have discovered that areas of the brain which are responsible for the identification of visual objects become active when the brain processes voice informational patterns. Put together both voice and visual activations resulted in better voice recognition. The areas in the human brain responsible for voice patterns and visual objects recognition interact directly and influence each other. 

The structural connection between voice and image  recognition areas combines visual and audio features via the direct connection consisting of fibre pathways between the voice recognition and the visual recognition areas of the human brain. The image virtualization is created by human brain on information received from eyes or from sensitive finger skin receptors scanning the soft Braille display Electro Active Polymers active matrix, as touch is the most widespread sense on the human body. New ways of applying the EAP tactile devices allow better use of sense coverage, involving more of the sensitive surface of the fingers, such that the EAP tactile display wrapped around finger like a band-aid, along with the voice information provided by the personal communicator to the visually impaired or blind people, together contain sufficient information to generate the visual virtual model of the topographic map in the human brain.
