or, Vibro Vest. Name suggestions encouraged!

Rachel and others are creating a vest that will allow the wearer to feel side-to-side movement behind them. This will be done by a set of motion sensors connected to a touch display (of pager motors, at least initially). The first prototype will have a one dimensional display so that up & down motion will not be detected, but this can probably be added later once some of the more pressing problems are solved. We have not yet made a final determination on the prototype sensors but have had some success with ultrasonic rangefinders.

[edit] Current Status

Full object is made but arduino is Broke due to plugging battery in backwards like an idiot. Need to swap out for a new one, or reflash the bios, or Something...

Integrate the shift register (wait until sensor decision is made? it would be cool to have an end-to-end thing...)

I (Rachel) have a fairly detailed mental model of the armature but have not made it yet.

[edit] Next Steps

  • Try out IR sensor? Daniela has lent us one, and I think there's some others in the bin plus of course the 900 PIR boards upstairs...
  • Buy the other US sensor I found? Its specs beat out both the Maxbotics and the PING))). Decide later.
