SimProj: A Tool for the Calculation of Rear-Projection Mirroring

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.

SecuVa – A Collaborative Gesture Framework Supporting Tabletop User Interfaces

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.

The TwinTable – A Multi-Touch Tabletop System for Tangible Interaction

The TwinTable is a multi-touch tabletop system that Simon Lehmann and I have built at the RheinMain University. After my previous table, the Virttable, we wanted to go for something bigger and with Full HD. Furthermore, our goal was a table that could be used in a living environment. Therefore, we have chosen a height of 50 cm, which is roughly the same height as a coffee table. This allows us to integrate the TwinTable into our laboratory’s lounge suite.

A Rear-Projection Mirror Fixture System for Multi-Touch Tabletops

Our multi-touch tabletop system TwinTable employs a rear-projected display with a diameter of approx. 46″. For the projection, we use an Acer H7350D DLP projector with FullHD resolution. In order to project the image correctly, we had to design a rear-projection mirror fixture system employing three mirrors.

A Few Impressions From ISE 2013 in Amsterdam

The ISE (Integrated Systems Electronics) is a »tradeshow for the professional AV and electronic systems industry«. If you are interested in multi-touch hardware like multi-touch tables, the ISE is the top venue in Europe. Therefore, I have attended the ISE in the last five years and want to share this year’s impressions with a focus on touch products.
