3D freehand pen computer interface

Found on Tinkernology and Makezine.com: http://tinkernology.blogspot.com/2010/08/sensor-input.html   http://blog.makezine.com/archive/2010/08/3d_freehand_drawer.html

This is a cool device that has gotten some attention. It's a computer interface that takes in 3D points. You manipulate a pen connected to an arm with joints and the pen's position is calculated. The author of the video made it himself with a PICAXE controller*, but I'm pretty sure expensive units can be bought for computer modeling (CAD).

*Similar to the Ardino microcontrollers I've posted about.


  1. Cool stuff! Slightly different paradigm, but have you ever seen the 3Dconnexion from LogitTec? They are not incredibly expensive (~$60 for the educational version) but allow full 6-degree-of-freedom control--also pretty neat.

  2. Yes I have heard about those, they look really cool. Apparently they're geared for CAD design.
