Great info on different projection techniques for VR video on Paul Bourkes site: paulbourke.net/dome/panodome/

castAR a Kickstarter campaign by technicalillusions that recently reached its 400K funding goals is developing a new pair of AR glasses. Two micro projectors one for each eye mounted onto a glasses frame either project onto a retro reflective surface or on a clip-on in front of the glasses. The projectors are running at 120 Hz. Apart from that a camera that is integrated into the glasses tracks a set of IR LED for position tracking. Overall they are exploring many different approaches to AR and 3D user-input. Have a look at the video for an in detail explanation.
The V Motion Project is a visually powerful Kinect based musical “instrument” that was developed by multiple artists for a marketing campaign.
On the technical side they found a very creative steam punk like solution for the problem of multiple kinects interfering with each other:
Matt Tizard found a white paper and video that explained an ingenious solution: wiggle the cameras. That’s it! Normally, the Kinect projects a pattern of infrared dots into space. An infrared sensor looks to see how this pattern has been distorted, and thus the shape of any objects in front of it. When you’ve got two cameras, they get confused when they see each other’s dots. If you wiggle one of the cameras, it sees its own dots as normal but the other camera’s dots are blurred streaks it can ignore. Paul built a little battery operated wiggling device from a model car kit, and then our Kinects were the best of friends.
Sorting through my archives i stumbled upon a CD with some pictures from an old project I did during my studies back in 2004, called globalexplorer. The main feature was a 3x9m projection screen we put up in the stairwell of our university.
A ticket equipped with a bar-code would allow you to “log in” at a virtual globe that allowed to select from a wide range of travel destinations around the world. This triggered a slide show of that destination on the main projection screen synced to some fitting local music score. The color of the lighting in the whole room was linked to the images as well.
As some well thought through marketing scheme 🙂 the number that was linked to the bar-code on your ticket would allow you to log in to a website to review the images of just the destinations you visited on the virtual globe. You could leave your address get some additional information or book your journey.
Looking back it seems amazing what we pulled of with six people a lot of sponsors but altogether zero budget.
Projecting onto buildings has become a somehow common thing. I have never seen it combined with interactivity and data visualization though.
Come to your Census[spinifexgroup.com] was developed by Spinifex for the occasion of Vivid Sydney, a spectacular festival around the theme of light which happened about one month ago.
The installation consisted of 3 different parts that visualized several datasets from the Australian Bureau of Statistics. The main interactive projection mapping showed data like Age & Gender, Country of Birth, Mode of Transport and Occupation of every postcode in Australia, which then could be interactively steered from a multitouch table in front of it. Another projection mapping displayed a normal infographics-based animation, while several interactive kiosks offered access to the ABS Spotlight website, an infographic story-tellingw website that describes several census statistics from a personal perspective.
Microsoft Research shows a very simple but compelling way to share your physical local desktop with a remote one.
The project called IllumiShare integrated a camera and a small projector into a desk lamp. This device allows to overlay the image captured from a remote desktop over your own as a projection.
