We recently published our first paper, entitled “Framework For Scalable Content Development In Hands-on Virtual And Mixed Reality Science Labs describing the technical features and preliminary usability data of our mixed-reality science lab system (https://ieeexplore.ieee.org/document/9815945). This paper won the best short paper award at the iLRN conference in 2022. Our second paper, titled “Miniaturization and geometric optimization of SteamVR active optical trackers”, highlighting our work to make cheaper mixed-reality tracking hardware for our efforts, was also recently accept in SPIE AR/VR/MR (http://spie.org/AVR01). We are confident that mixed-reality science labs offer a uniquely enabling path to cost-effectively training the STEM workforce of the future and are grateful to NSF for investing in our project and this general category of approaches for STEM laboratory training and workforce education.
