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.

.htaccess Forward to New Domain with URL Parameters

If you move your web page to a new domain, you may want to forward users (and search engines in particular) that still access your page via the old domain to the new domain. However, if you use an underlying CMS or blog system you will want to keep the parameters after the domain name. E.g., if someone called http://olddomain.com/lang/en-us/living-with-complexity you would want to forward it to http://newddomain.com/lang/en-us/living-with-complexity. For this purpose, I found the following .htaccess snippet handy:

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.
