Web VR
Emily Hobby
NIST SURF Research Associate, Summer 2017
Agenda
- Making 3D models interactive in webVR
- Information about scientific instruments and laboratory (or other non-public) spaces
- Taking advantage of Web infrastructure for 3D graphics
Background
- Virtual reality
- An immersive 3D experience
- The user can interact and explore this environment
- WebVR
- Virtual reality in a Web browser
- Can be used with Google Cardboard, GearVR, Oculus, and Vive on MS Windows; MacOS; Linux; iOS; Android and so on
Scanning Tunneling Microscope
Access to Information
Allows user to have hands-on interactions, set their own preferences, and explore the microscope in virtual reality
Preferences and Raycasting
Part Selection and Inspection
Designing with VR in mind
- Heads Up Display for showing information
- Menu visible and changeable in VR
- Joystick control, in hands, for easy navigation
STM Demo
Use with Different Hardware
- Traditional VR requires different versions to work with different hardware
- The STM model can be used in browser and Oculus, without having to use 2 different versions
How does this help?
- For researchers and scientists to become familiar with delicate equipment
- For facilities to monitor equipment
- For the public to explore a scientific model
NIST Library: 360 degree walkthrough
360 Video Authoring Process
- Take videos at different locations around the library using Samsung GearVR 360 camera
- Stitched together using Samsung ActionDirector camera
- Had to be a camera capable of taking 360 degreesx360 degrees
Walk-through of Real Spaces
- Explore in a space not typically accessible to the public
- Video portion made with an hour in the space
- Information can be location-based
Conclusion
- VR is a new way to represent data and information
- WebVR improves ease of access
- Models and walk-throughs in browser lets hands on exploration and location-based information feasible
