How we use Bridge to create affordable 6DoF VR

At StoryUP, we’re constantly looking for ways to make our inspirational content more immersive. So, when we spotted this new technology from Occipital, called Bridge, we realized we might be able to use it to create room-scale VR with 6 degrees of freedom.

Here’s how it works.

What is Bridge?

In brief, Bridge is a headset system that allows users to copy and reconstruct real environment and let them immerse into the environment and interact within it.  

What’s in the box?

Bridge Headset

  • Bridge Headset
  • 120º Wide Vision Lens (already attached to Bridge headset)
  • Bridge Controller (3-DoF)
  • AAA Batteries (2x)
  • Bridge Lightning Cable
  • Alternate Face Pad
  • Alternate Lens Spacers
  • Lens Cleaning Cloth
  • Bridge Headset Quick Start Guide
  • Bridge Controller Quick Start Guide

Structure Sensor Package

  • Structure Sensor
  • Lightning Cable
  • AC Power Adapter
  • Screwdriver
  • M1.6 Screws (8x)
  • Structure Sensor User Manual

How to use Bridge for the first time?

1. Sorry, Android users! You need an iPhone (6,6S, 7,8)

2. Charge the Structure Sensor

3. While charging, download these two apps: BRIDGET (a mixed reality robot) and a Structure Sensor Calibrator. BRIDGET is the main app that we would actually use to experience mixed reality, while the second is an assistant app that we need to calibrate Structure Sensor in order to let iPhone and the sensor work together. You’ll need to open this one before you open the main app.

4. Download a calibrator checkerboard, like this one.

5. Attach the charged structure sensor to the headset. A screwdriver and screws come within the package.

6. Assemble the headset system as below.

7. Display the calibrator checkerboard to full-screen on your monitor and open the structure sensor app and calibrate the gear by following the instructions.

8. Users cannot wear the headset with glasses, however, people who are nearsighted can replace the installed lens spacers with the other two backups.

9. After calibration, open the app BRIDGET and plug the lightning cable into iPhone. Make sure your phone has enough juice. Once a low-battery level notification pops out, users have to reopen the app and start again.

10. Then press “trigger” to launch the app.

11. Scan your surrounding environment by moving the headset. You should try to scan the environment as completely as you can in order to get a better result. Also, walk around and try to scan objects from different angles.

12. Now you can immerse yourself into the world of mixed reality! Look at the Robot to active him and select interactive activities by pulling the trigger.
