light box interface

Thursday, September 14th, 2006

im march fraunhofer igd presented an installation about photorealistic rendering at CeBIT 2006 in hannover. the stereo projection shows an high detailed 3D model of a BMW in photorealistic quality.

i created the “light box interface” for this installation. it’s a table with 8 different polaroid photos of the car on it with an integrated aluminium powermate wheel. touching a photograph activates the camera position in the 3d scene shown on the photo. thats the link between “photorealistic” and “rendering”. touching a photograph reveals an identical looking real time image on the projection.

there are touch sensors under each polaroid that activate the camera position on the photo. the touch sensors are simply connected to button pins of an usb gamepad. the wheel lets the camera rotate around the car.

the light box interface is a very easy to use interface furniture.

felt nintendo ds lite cozy

Thursday, September 7th, 2006

these are the grey felt cozies for my nintendo ds lite and my mobile phone. i designed and created them together with birgit. they are designed as simple as it could be. five closed sides and one open. sewed together with simple stitches.

[update] the cozies were mentioned on o’reilly’s craft weblog.

mixed reality chainsaw

Thursday, September 7th, 2006

seit anfang des jahres arbeitete ich am igd an einem mixed reality projekt fuer den kettensaegenhersteller dolmar. dabei ging es um die simulation von arbeitsszenarien mit dolmars neuer kettensaege ps-5000. ergebnis der arbeit war die simulation der waldarbeiterdisziplin “scheiben schneiden”, bei der eine gerade scheibe mit einem bestimmten gewicht zu schneiden ist. die konzentration lag dabei auf der entwicklung einer software/hardware loesung zur realistischen vermittlung des arbeitens mit einer kettensaege (haptik, technik).

die simulation besteht aus folgenden komponenten:

- projektion eines bauernhofszenarios (igd avalon / instant reality)
- positionsbestimmung einer modifizierten kettensaege via optisches led tracking (igd visionlib)
- haptiksimulation über sensorgesteuerten saegebock aus acryl und mdf (arduino)
- modifizierte kettensaege als interaktionsgeraet – force feedback, gasgriff, anlasser (logitech wireless rumblepad)

das projekt wurde zur gafa 2006 in koeln vorgestellt.

at the igd i was working for some month on a mixed reality projectfor the chainsaw manufacturer dolmar. the goal was to create a simulation of a lumberjack discipline – cutting disc with a certain weight – with dolmar’s latest chainsaw model ps-5000. we concentrated on creating a hardware / software solution for a realistic experience of working with a chainsaw.

the simulation constists of the following components:

- a projection of a farm scenario (igd avalon / instant reality)
- optical led tracking of the modified chainsaw (igd visionlib)
- haptic simulation via a sensordriven sawbuck build of acryl and mdf (arduino)
- interaction device: modified chainsaw – force feedback, throttle, starter (logitech wireless rumblepad)

the project was presented at gafa 2006 fair cologne.
