Bluetooth Stylus for 3D drawing with motion capture systems.

 
 

This video demonstrates the use of our wireless bluetooth stylus for 3D drawing with an Optitrack motion capture system.This project was a collaboration with Madeline Gannon for her Human-Robot Interaction Research.

 
 

Stylus
 

How it's made - Built on the Lightblue Bean bluetooth micro-controller (Arduino compatible), this stylus incorporates a capacitive sensing circuit to sketch directly on the body when the tip comes in contact with the skin. Additionally, it features a momentary push button circuit, enabling the user to execute freeform 3D drawings. Circuit details, code and .stl are available at Instructables.com.

Goals - This work is part of larger research in Human-Robot Interaction. The goal is to unify the worlds of the Optitrack Motion Capture System, a UR5 robot arm and a human. This stylus enables us to relate an object to its virtual counterpart using a tangible and familiar interface.
