the vOICe
How does it work?
left and right
Video is sounded in a left to right scanning order, by default at a rate of one image snapshot per second.
up and down
Pitch means elevation: the higher the pitch, the higher the position of the visual pattern.
dark and light
Loudness means brightness: the louder the brighter. Silence means black; a loud sound means white.
Other Technologies
Tactile sense pad to help the blind see Cameras with connections to visual cortex to override damaged retinal nerve Thought Translation Devices
An "EEG" net to detect changes in electrical signatures Different amplitudes are linked to different cursor movements
Correlation
Match between observation and felt sensation
The "two-foot" nose Class example: drawing of hand on table
Correlations between sensory inputs as well as motor outputs: The brain relies on perceived correlations to construct a sense of body boundaries
""There is no self, if by self we mean some central cognitive essence that makes me who and what I am. In its place there is just the "soft self": a rough-andtumble, control-sharing coalition of processes--some neural, some bodily, some technological..." --Andy Clark, NaturalBorn Cyborgs
