Sensory Substitution

Figure 1. Vision Substitution by Tactile Image Projection by Dr. Paul Bach-Y-Rita in 1969. The T.V. Camera records the object and sends the stream to commutator which translates this image into motion of vibrators which then projects this image on to the skin of the back of user sitting on the chair.

Technical Implementations

Figure 3 (a). Proposed position and placement of disc vibration motors on hand. Each circle in the above illustration represents one disc vibration motor with its corresponding identification number.
Figure 3 (b). Initial implementation and layout. The right half of the image shows planned layout of vibrations motors which are used for vibration and placement of Arduino Nano
Figure 4. Schematic for connection 16 vibration motors (M-1 to M-16) to Arduino Nano
Figure 5. Implementation Block Diagram
Figure 6. The motion of indicating a ‘move straight’ gesture. The time interval between each frame is 120 ms and on time for each frame is 100 ms.
