Holo-Classroom, Holo-Conference

Development Effort: 8/10
Business Value: 8/10
Wow Factor: 9.5/10

I have posted Holo-Tutor a couple of days ago, so is the Holo-Classroom any different? Yes, but this is an extension to that. In Holo-Tutor I was talking about one-on-one tutoring. The implementation is almost zero effort for both parties: the tutor and the students. No special software is required. Holo-Classroom is more like a video conference, which requires Skype to add special holographic conference support. That’s much harder in software implementation. Lets assume Skype holographic video conference call is available.

The idea is to create a virtual class/conference room. The room is selected by whoever started the meeting, the teacher in the case of Holo-Classroom. People who join in appear in the room. You can take a seat of your choice. Everyone see each other in forms of 3D avatars. Your avatar do what you do: stand up, sit down, raise hand to talk. In the case of classroom, the teacher can have a virtual white board behind him. He can write on it, or show PowerPoint on it.

Admittedly, this is not a fresh idea. I remember same concept was shown in the context of Kinect, which didn’t happen. I think the technology just wasn’t advanced enough at that point. I wonder if it is ready now, but I think the only thing that prevents it from happening is how much data has to flow on the Internet. If it is too much data, then the Internet wouldn’t be able handle it. For the intranet (LAN) connection, use cases are much limited.

This is big deal for teaching, because group lessons are much cheaper than personal lessons. If one teacher can teach 10 people at the same time, it will be much more affordable.

One caveat though, I have also assumed HoloLens can detect body movement in addition to hand gesture. This is something I am not confident with. If it can’t, things like sitting down would have to be controlled by clicking a button or things like that.
