I work with micro-controllers (Arduino, EZIO board, etc.) to connect various sensors and input devices to real-time applications, for example for the Jetski project.

Designed and built new input devices like Multi-touch Interface or V-Ramp.

Connected a Logitech WingMan RumblePad to use for real-time applications (over Logitech's Profiler and over DirectX / VRPN).

Connected sensors or devices (WM-918 weather station) to log data, store data in databases, make data accessible on web servers.

CAVE

I experimented with University of Michigan 3D Lab's CAVE for many years. I was interested in improving the human computer interaction in realistic immersive environments. I programed the CAVE, created and converted content, implemented projects, and worked with ImmersionGraphics on upgrades and maintenance.
I created with the help of several students programming libraries to make the CAVE usage easier.

The University of Michigan 3D Lab's CAVE has four walls (1024x1024 each) and a Vicon motion capture system.

Wide-Screen Projection System (AccessGrid)

I experimented with tiled projection system. I started with the AccessGrid which was designed for video conferencing. It used 3×1 projectors (3072x768) which allowed for the presentation of multiple data sets and video streams. I helped to build the system and operated it for many conferences. I worked with Internet2 for the special network requirements.

After upgrades I experimented with the system to use it for demonstration and exploration of 3D data in real-time.

Stereo Projection System (GeoWall)

I helped setting up the first couple GeoWalls in Michigan (University of Michigan: Geological Sciences).
I was cruicial in desinging six more systems (University of Michigan 3D Lab, University of Michigan: Department of Emergency Medicine , University of Michigan: Architecture, University of Michigan: ERC/RMS, Detroit Science Center, and Cornell University: Cinema).

High-resolution Tiled Display (GeoWall2)

At the University of Michigan 3D Lab I set up a small 7.5 megapixels system with 3×2 screens (3840×2048) driven by just one computer. I also built a big 35 megapixels system with 4×4 screens (7680×4800) driven by eight display computers and one control computer.

Vicon Motion Capture System

I worked with the University of Michigan 3D Lab's Vicon System which uses 8×MX13 cameras. I calibrated the system, set up markers, and recorded motion. I also worked on the integration as a tracking system in a CAVE environment.

Tracking Devices

I experimented with Ascension's "Flock of Birds" and Polhemus' FastTrak. I wrote software to talk directly with the box over the serial protocal. I also integrated the trackers to various real-time software toolkits using client/server application like trackd and VRPN.
