The experience uses MRTK for crossplatform interactions, Photon Pun 2 for networked interactions and is hosted with github pages. This project has been developed by the NASA GRC GVIS lab in support of the EPFD project. This test was performed in the Boise State University Stein Luminary CAVE which is running a desktop instance of the WebXR Rover demo on the walls, while the Quest 2 and HoloLens 2 also interact with the same virtual rover through the web. Supported Devices: HoloLens 1&2 (Native browser support), Quest 1&2 (Native browser support), PCVR (WebXR API Emulator Plugin), Desktop (Native browser support), iOS (Mozilla WebXR Viewer because Safari doesn't support WebXR) and Android (Native browser support)

HoloLens 2 Low-Light Solution

This is a brief video showcasing the BSU NASA SUITS team's solution to low light scenarios with the HoloLens 2 which requires light to spatially map the environment. Our team 3D printed a mount for a powerful 1500 lumen light allowing us to provide sufficient light to enable spatial mapping functionality in unpredictable environments. This was done for our ARSIS 5.0 software as part of the NASA SUITS 2022 challenge (Spacesuit User Interface Technologies for Students) in which our software solution was tested in a dark environment to mimic the lighting on a lunar EVA.

Passthrough Multiplayer MRTK Quest Sample

This is my open source sample implementation of mixed reality passthrough multiplayer handracking in the Quest 2 utilizing Unity, Mixed Reality Toolkit, OVR Integration (Oculus), and Normcore for network functionallity as well as Eric Provencher's "Networked Manipulator" script to allow hand tracking data transmission over a network. I might look into updating it slightly moving forward however I plan to leave this project as a boiler plate for people to work from so I don't want to put too much stuff in here so it's easier to replicate.
Unity, C#, Multiplayer, Crossplatform, MRTK, Photon

Co-located Crossplatform Multiplayer AR

This is a native crossplatform augmented reality experience allowing up to ten users to interact with a NASA rover together in both remote and co-located space. This experience supports: HoloLens 2, Quest 1&2, iOS and Android. The project utilizes Mixed Realtiy Tookit to achieve crossplatform interactions on all XR enabled devices, photon to synchronize the interactions from various users over a network, and Unity engine to build to any XR enabled platform.
MR/AR/VR, Unity, C#, Quest 2

Oculus Interaction Passthrough Hand Playground

This is a demo build of Oculus Integration's recently released hand interaction samples. I implemented Oculus Passthrough functionality into each of the scenes and added a "Toggle Passthrough" button to swap between a full passthrough or a blended virtual environment. Huge shoutout to Oculus for releasing this incredible hand interaction sdk! To create this demo I simply: Imported Oculus Integration into a blank Unity 2020.3.8LTS project. Implemented OVR passthrough capabilities in each of the demo hand interaction scenes provided by Oculus Added a "Toggle Passthrough" button to toggle between the full passthrough environment and the blended virtual environment. Built all of the demo scenes to the Quest! NOTE: These samples were created by Meta.
Cesium, Meta/Oculus Integration

Dynamic Realworld Environments in Unity with Cesium

In this project I setup a demo of Cesium for Unity deployed to the Quest 2. The Quest 2 references the Cesium API on start up and populates the environmental mesh and textures based on satellite data sets for that location. In the beginning I showcase the real-world location in google maps and then open up Cesium for Unity on the Quest 2 and pull in the data for that same location. If you pay close attention you'll notice the same buildings, and even the same vehicles parked on the side of the road between the google maps street view and Cesium's Environmental Mesh in Unity.

Fully Interactive Neuroanatomy VR - Quest 2 Passthrough

This is an improved implementation of Chris Larkee's open source Neuroanatomy VR project in Quest 2 Mixed Reality Passthrough. For this solution I updated the project to a version of Unity compatible with mixed reality passthrough, manually added the necessary components for passthrough functionality and removed the virtual backgrounds from the scenes as well as implementing a simple passthrough color configuration tool. Try it yourself on SideQuestVR.

VR Spellcasting

This is a simple VR prototype game in which the player can can cast spells using different VR control scheme combinations to shoot down enemy bats. The fire attack is a basic ranged attack that can be fired using the right trigger button. The water attack uses the left trigger button and pushes enemies back, helping the user buy time. The wind attack is a powerful ranged attack that can be created when the user puts both hands together. The lightning attack is created by holding the "A" button and making a forward throwing motion with the right arm.

VR Gesture Recognition

This is a prototype I'm currently working on with the ultimate intention of improving my VR spellcasting game. In its current form, the software displays a military physical command signal on a UI canvas in front of the player. The player then mimics the command, if it is not close enough, the UI will display that their attempt was incorrect, but if they get it correct, the UI will move on to the next hand signal until all signal are successfully completed at which point the player can make whatever signal they want which the software will recognize and match to its list of signals.

Unity, C#, VR

Virtual School Bus

Developed for Invent For the Planet 2019 Our challenge was to conceptualize and prototype an application of Virtual Reality to benefit the community within a 48 hr time period. Ultimately we settled on a Virtual Reality language learning game that would strive to fully immerse the player in the world of the language they are trying to learn helping them form stronger mental connections with what they are saying/hearing. We used Oculus OVR plugin with Unity to create a VR recreation of a Japanese city that the player needs to traverse by speaking Japanese with NPC's. This forces the player to speak conversationally and think more reactivley as opposed to following scripted conversations and responses. The ultimate goal of this is a more efficient and effective learning experience. Ultimately we didn't get the language translation to be fully functional due to lack of time, but we got a simple prototype working and managed to take second place in the competition.
