As I mentioned earlier, I augmented one of the T-Sticks with a vibration motor designed by Hsin-Yun Yao and Vincent Hayward of McGill’s Haptics Lab. Since then, various incarnations of the T[actile]-Stick have been used for pursuing research at McGill on Enactive Interfaces. Recently I finished building a prototype with multidimensional vibration feedback: a wooden harness is used at each end to mount two linear vibration motors orthogonal to the length axis of the pipe. This allows stereo panning effects along the length of the pipe, and will hopefully lead to some more sophisticated haptic effects than I described in my initial project report.
