Digital Pen and Paper: Episode 1

Detecting a sheet of paper and a simple IR pen within a camera/projector setup. Quick and dirty demo recorded 2010-05-14 at home in Hamburg. Music by Artbitch (Schwarz/Maklott)

Touchable Table’s last (?) demo

This is my multitouch table’s status as it was last documented (in June 2009). The table is still at uni, available for students to experiment.

In the video, you’ll see:

- raw display of the analysis image (b/w) and touch points (green).
- simple b/w drawing
- radial menu (triggered by a loop glyph)
- control of Alex Schieve’s LargeImageRenderer (showing a microscopic picture of some liver tissue)
- “cards” demo - moving around some pictures (notice how they “lean” when moved and have a shadow)
- a short 1-player demo of my multitouch pong
- particles demo
- 2-D physics demo
- touch keyboard demo (”Today, the keyboard seems to work OK.”), and an old slider
- more raw analysis (notice how the green circles get larger when I press harder)
- prediction demo (notice how the line ends quite exactly at the fingertip, not 1-2cm behind it due to latency)

Some of these have been developed in my time Bauhaus-University Weimar’s VR Systems Chair.

First public appearance of (my) Multitouch Pong

Short video documentation of my multi-touch-sensitive table project running a remake of the classic “Pong” game. Prototypical hard- and software with many errors/imprecisions. Presented at our village festivity in Engerazhofen, Germany to a bunch of local kids.
