Gain new senses, like for example being able to feel the cars around without looking into the rear mirror, or having a bird eye view while seeing normally from the ground level too, or giving vision to blind people, or feeling the Internet traffic, or any other things like that.
No implants are necessary, but requires some training.
The project is based on mapping a 2D matrix to a 1D vector using Hilbert's Curve. The 1D vector can be feed to the brain as an audio signal, transmitted directly to the internal ear through bone conduction.
In theory, anything that can be represented by a 2D matrix (like a screen) can be mapped in a 1D vector (like an audio signal).
The required training is for teaching the brain how to make sense of the new stream of information, and for how to use the new senses together with the already existing ones.
What will be the maximum audio resolution? How much extra data can be fed to a brain? How long will be the training? Will it work?
