Zspace Linux Fix

Project Overview

The goal of this project is to create a fix for the zspace's stereo display of content, which gets mixed up from time to time. Using additional hardware external to the computer, a fix can be made which determines if the screen is correctly initialized and displaying content with the proper stereo orientation.

Milestones

• Power the light intensity to frequency converter via an Arduino Uno.
• Obtain light intensity measurement by reading frequency from the diode.
• Write an application to read/write light-intensity to/from the Ardunio Uno by means of a tty device (e.g. "/dev/ttyACM0").
• Create a cable with the special diode fastened in place behind a polarized lens.
• Test the cable to make sure the polarized lens makes a difference when switching left/right screens in CalVR.
• Integrate code with CalVR to show proof of concept.

Known Bugs/Issues

• The ZSpace has a 50/50 chance at initializing the left and right images in an inverted manner.
  • Must be detected so screens can be inverted [again] to their correct positions.
  • Requires additional hardware to monitor which screen is being displayed.
  • Arduino Uno serves this purpose and reports light frequency back to host OS.
