In Summer 2020, I interned with Google as a software engineer within the Front End Analytics Team. The challenge was to create another way to explore data - not just 2D interaction but bringing the data to life.
This open-source project was an exciting way to experiment with data visualization, providing a foundation for (more literally) interacting with data in new ways. Over the course of 12 weeks, I built a VR scene from scratch, using virtual reality tools (A-frame) and then adding data visualizations tools (D3) to the mix.
Web Version: WebVR only allows support for 2D movement so I was able to implement a solution that facilitated movement in all directions, using the W-S keys for z-movement, A-D keys for x-movement, and Q-Z keys for y-movement.
Mobile VR: Google Daydream also doesn't easily facilitate movement within a VR space, so I defined my own interface by adding arrow keys for all movements, which appear in front of the user at all times.
Panning + Hover Card Focus
Web Version: Panning is harder in web because one has to use a mouse, but the mouse can still be fixed to read the values of each data sphere.
Mobile VR: Panning in Google Daydream is as easy as a turn of head and information on each of the hover cards can be read by pointing the controller at the point.
