Episode 459: Raspberry Pi 4 VR Conference Call Assistant

It’s difficult to take part in conference calls. The 2d nature of the call doesn’t allow social interaction. What if you could look at people in your conference call using a virtual reality headset? A picture of you would move left and right as your head moves left and right. Other attendees can look around and chat to the person they want to talk to. Lorraine shows how to setup a first person view raspberry pi that connects to a virtual reality headset or a simple browser window. This project has lots of potential outside of conference calls such as security cameras, nature cameras and first person view robots.

    I like the idea and had thought about a telepresence robot for when I'm working remotely and the rest of my team are back in the office.

     

    Have you see Ross Atkin's Smartipresence robot using cardboard…

    hi Andy, thanks for the links. Yeah, I love Ross' robot! https://www.kickstarter.com/projects/rossatkin/smartipresence-cardboard-telepresence-robot

    Hi Dave,

    In a conference room, sitting around a table you won't really be able to just move your eyes to see everyone. You'd have to be sat quite far back!

    Video of the other people would be awesome…

    Hi Lorraine,

     

    a great project. I have two questions: the first is if the software you used is planned to be published somewhere and the second is what kind of algorithms you used to move in-synch the two servos for non-euclidean 3D space positioning of the camera.

    Hi Enrico

     

    Heres the code

    https://github.com/Lorrainbow/headconf

     

    During the video I thought i got the 2nd servo working up and down but it wasn't actually fully working. The 2 servos never worked together- for example the head didn't move diagonally.

     

    I used eulur angles. Quaternion angles would have been better but I couldn't get my head around the maths.
