WebXR Study Group meetup Friday August 10th, 2018 5pm to 9pm at Noisebridge 2169 Mission St, San Francisco, CA.

Study WebXR for Brain Computer Interfaces: Study Group (Neurotech SF WebXR BCI) at Noisebridge with San Francisco Virtual Reality and NeurotechSF.

How to find us: We will be on the 3rd Floor, by the Mission St Windows, at the Collaboration Station, at the far end of the Hackitorium (close to the Mission St side I mean). You will need to ring the door bell to get into Noisebridge.

The WebXR Study Group is a continuation of previously Neurotech SF VR meetups where we were able to connect EEG with WebVR via the Brainduino EEG device, and Mozilla’s aframe.io Now that we have accomplished that milestone we are becoming a study group, to examine how to further use WebXR for Brain Computer Interfaces.

Questions we want to answer as a group: How can we visualize biofeedback VR in 3D with WebXR? How can we integrate FFT Fast fourier transform? What else can we do to process the signals and creating amazing visual feedback in WebXR for VR headsets and AR phones/tablets.

Lets spend some time learning to code WebXR.

You can optionally bring your own stand alone vr headsets to test WebVR apps with. (like Oculus Go or Mirage Solo or Vive Focus for example) and your own laptop to develop your own WebXR application, and you can test your webXR application with our Brainduino and our Oculus Go if you like.

About NeurotechSF: The global objective: NeurotechX is a global organization of Neurohackers with 17 chapters worldwide.

This document is regarding the San Francisco branch of Neurotech and a second meetup called San Francisco Virtual Reality that was founded by Matt Sonic. As an organizer of both meetups, and as an organizer of some Noisebridge meetups I have been combining these meetups at Noisebridge because I believe that Virtual Reality and Augmented Reality software development and hardware devices are on track to converge with Brain Computer Interface and Brain Machine Interfaces.

The local objective of the NeurotechSF & San Francisco Virtual Reality meetups is currently to merge Brain Computer Interfaces with XR (XR is a single API that does both Augmented Reality + Virtual Reality) and AR VR headset and combine these with Machine Learning (Deep Learning Artificial Intelligence) and possibly also create 3D point clouds of data from medical imaging and 3D point clouds of data around a participant, and do correlations between BCI data and environment data, that can include virtual environment data. We also want to create next generation biofeedback data visualizations and next generation user interfaces that predict users intention and emotion at the interface of AR and VR with the biofeedback and machine learning.

The objective of this specific new series (this document is about the 5th in the new series that started Summer 2018) is to combine the brainduino with the oculus go via webXR.

Our upcoming goals include

  1. Broadcasting our html page to the open web, with the webvr & the brainduino EEG live stream going into the open web so we can access it from inside the Oculus Go.
  2. Some thoughts are that we could rewrite the server code in python, or node.js, or in the Go programming language)
  3. Migrate from aframe WebVR to the new WebXR protocol, and form a study group to study the WebXR API together so we can learn as a group how to use it effectively.
  4. Build or integrate FFT (Fast Fourier Tranform) into the pipeline between the Brainduino and WebXR. So we can get the component waves, Alpha, Beta, Theta, Delta, and Gamma from the brainduino and display them in VR, and or at least create visualizations from the component waveforms.
  5. Formulate a study group to will explore how to send data into Tensor Flow (Deep Learning) via Keras and how to receive the output back into WebXR.

Previous Progress: We made significant progress at the July 29th, 2018 meetup: We were able to cause voltages from the skin to move objects in WebVR. Watch the video that explains the recent progress we made in our Sunday July 29th meetup. https://www.facebook.com/worksalt/videos/2332211350138832/
