I want to build a helmet that has an accelerometer attached to it which finds the position in space relative to g and converts these signals into very weak electric currents which will sit on a tongue plate and give the person who wears it an alternative way to receive vestibular input (my son has no vestibular function and as a result very wobbly and cannot walk) I am totally new to this, and have no clue about electronics or programming but I am desperately eager to learn from y'all. Any input or guide into the right direction means very much to me. I dont know exactly how the accelerometer treats or processes the information about movement in space, but I am familiar with vectors and I wonder if it could be as simple as just attaching 5 little wires to the arduino board: +i, -i, +j, -j and - k. k would represent vertically upwards from the surface of the earth. there would be no positve k- axys because I dont know where to put it on the tongue. THe tongue plate would be rectangular (very small, 10mmx5mm) and the 5 electronic cables end in it like a cross arrangement, +i translates movement to the right and gives an impulse on the right side of the tongue, -i is to the left and gives in impulse on the left side of the tongue, +j is forward and send an impulse at the front of the tongue and -j is at the back of the tongue and sends an impulse when the accelerometer detects backward motion. -k is for downward motion and I would put it right in the middle of the tongue. so when the accelerometer detects downward motion the middle of the tongue tickles. The magnitude of the acceleration governs the strength of the current, sudden strong movement causing a stronger current. positional changes which are in directions which are made up of i-,j-, and k- components will result in different areas of the tongue being stimulated simultaneously by electric impulses. like a movement from (0,0,0) to (2,0,1) would mean my head goes to the right and downwards, but twice as much to the right and not forward or backwards. so 2i+k and the right side of the tongue would receive a current twice as strong as the middle, whereas front and back of tongue dont receive any impulse. Can I use the arduino Uno board to act as the intermediator between my accelerometer and the tongue plate (which will be 5 wires held together by half and inch of scotch tape on both sides) and how do I get it to break up the info from the accelerometer into currents of varying strength into these 5 wires? Thank you for reading up till here.
