Unreal Remote Streaming Multiplayer to the Hololens 2

by

For our therapy app it would be highly beneficial if the therapist could also wear a headset and engage in the experience with the patient. That way they will be able to guide patients through the learnings easily. To do this with Metahumans I will need to use remote streaming from a PC so that the heavy lifting is done by the PC and not the Hololens. I’ve finally got it all working – just with basic shapes for now, but next stop will be Metahumans!

UE4 Hololens Multiplayer

by
After a bit of an enforced break due to catching COVID, I’ve started back on our therapy app looking at how to make a multiplayer Hololens experience. Therapists will be able to join patients in the therapy to guide them and encourage positive outcomes.

I found two excellent resources that showed me how to do this.

MHC Lighting Presets

by

Epic have released MHC Lighting Presets – A set of lighting set ups designed by Greig Fraser (Dune) and they are free to use in your Metahuman setups.

The presets enhance the render of your Metahumans in the Hololens, but I had to make a few edits to the settings when I copied them into my Unreal Hololens Project setup. So if you find they don’t quite look the same in yours, then check out what I did here.

Alpha Demo

by

I’m starting to get the hang of all things Unreal and Hololens 2 so I’ve done a very basic app with the main requirements in rudimentary form. I’ve just used Mixamo animations to start with but will create some much more fine tuned and subtle animations soon.

Metahumans in the Hololens 2 – First Steps!

by
Starting research into the uses of AR in Speech Pathology Therapy. How viable is it to use the Unreal Engine Metahumans and Microsoft’s Hololens 2 in apps designed to expose patients to various emotions portrayed by body language and facial expressions. Can we use the gaze detector to determine where patients are focusing so that therapists can help to shift concentration to the important areas. This is the very first step – using Metahumans in the HL2. The HL2 recording doesn’t show the quality of the humans, but as I went up close, even knowing it was a projection, I still expected him to turn and face me. So incredibly real.

Epic MegaGrant

I’m astounded to be able to announce that I have received one of the Epic Games MegaGrants!

With it I will continue research with Lucy Bryant of the UTS Speech Pathology Department into using Hololens technology to benefit patients.

Watch this space for updates on what we’re creating together and how it will contribute to exciting developments in future therapies.
