Thinking beyond isolation and social distancing. The future of technology in the classroom is exciting. Carleton has invested in a lot of innovative tech for moving into the future, we managed to get a hold of four Hololens. Unlike the HTC Vive, which is VR, the Hololens is AR (Augmented Reality). The Hololens is an impressive piece of kit and one I am the most excited about. According to Microsoft (its developer), the Hololens is “the first self-contained, holographic computer, enabling you to engage with your digital content and interact with holograms in the world around you.” In normal terms, it is a tiny computer attached to a set of glass lenses, which look like a very futuristic headset.
These lenses are where the magic happens. The Hololens has three layered screens for Red, Green and Blue channels, which are combined to render full-colour objects. The onboard computer uses an inertial measurement unit to calculate the location of you and the `holographic’ object within your surroundings. This technology works in a similar way to AR on your cell phone with games like Pokemon Go and Ingress.
The Hololens opens up some fascinating teaching possibilities. Unlike the Vive and VR, which is very isolating and a single user experience, the Hololens and AR can be developed to be a multi-user experience. This multi-user experience enables each Hololens to view the same 3D, providing some exciting possibilities within the class.
One of the first projects we worked on was to develop an AR model of the Piper J3 Cub used to train Carleton students in the 1940-50s. This was a part of a museum display for Sesquicentennial celebrations. The original idea of this project was to utilise the VR and HTC Vive, but I felt the Hololens would be more fun for Visitors and would still allow them to be present within the space. Thank you to PEPS for editing one of my favourite videos using the Hololens.
