The SimProj Project provides a Processing-based (and therefore Java-based) application that provides a GUI for the simulated calculation of a video projection setup. SimProj allows to add and manipulate virtual projectors, mirrors and projection planes in order to show how the projection is mirrored and which sizes, angles and positions the setup components require. SimProj can be configured to comfortably show all necessary measures that can be ‘easily’ (everyone who has ever built a rear-projection setup knows what ‘easily’ means in that context) transferred to the hardware setup.
In the course of his Master thesis at the Hochschule RheinMain, Tim Hofmann researched the possibilities of collaborative gestures on tabletop user interfaces. I supervised his thesis and am really impressed what Tim has created.
At the Hochschule RheinMain, we experiment with tangible user interfaces (TUI) a lot. We are especially interested in improving the authoring process of TUIs. On one hand of the creation process is the software issue how the interaction and the user interfaces can be designed and developed. However, on the other hand, there stands the problem, how the actual physical tangible objects have to look like and how they can be created. Continue reading “A 3D-Printable Set of Tangible Objects”
Recently Douglas Engelbart passed away. He is popular for his human-computer interaction research and famous for a demo session which has been named »The Mother of all Demos« on December 9, 1968. In this demo session he introduced the computer mouse, hypermedia (which lead to HTML) and word processing (plus many other techniques). Watch the video above to see the demo.
I love the Dr. Strangelove-ish spirit of it. If you do not want to watch the whole demo, just put on headphones, switch to another task and enjoy Engelbart’s soothing voice.
A professor from my university bought a Lytrolight field camera. We played around with it for a while. Although the Lytro’s form factor is different, you take pictures with it just like you would with your average digital camera. Simply push down the release button and you take a picture. The camera stores the pictures on its internal memory and you have to hook up the Lytro to your computer to download the pictures using the Lytro software. As the camera uses a proprietary format to store the pictures, you have to use the Lytro software to watch them. Continue reading “Playing Around with the Lytro Light Field Camera”
