HHJ Interaction - Art - Technology


On this page I will show you the projects I have made and been part of, together with details of how they were accomplished. I will explain both the concepts and the technology behind it. On the relevant projects i will put up the source code, so hopefully other people (you) can use it, or comment on it, for the purpose of mutual knowledge expansion.

Co-creation with children at the Cph Opera

For this project I designed and built a software that allowed children to control and record shadow animal animations through their body movements. These animations were use as part of the visualization of the narrative in a classical concert, as back projections on the stage.

Chaotic Flow - 4S/EASST conference

This project I did together with Tobias Lukassen and Johan Bichel Lindegaard, two other members of Illutron, a Collaborative interactive art studio i'm part of.

Phono Info Point

A info point installation made for Phono Festival 2012, an electronic music festival in Odense taking place in a old slaughterhouse. The installation used a kinect to track peoples hand movements, which they used to explore images and text descriptions of the performers of the festival. The visualization was made to fit the dark insustrial building, and were projected on a uneven projectionsurface put together by arbitrary sized white squares.

Hydrophonic Soundscapes

Hydrophonic Soundscapes was a Illutron project build for Helsinki Festival on August 2011. The installation transformed a pool in the middle of Helsinki centre into an interactive sound and light installation. Several hydrophones captured all the sounds the audience made; for example splashing hands or throwing stones into the water. Whenever there was interaction in the water, three lights changed their colour regarding to the amount of pressure. Eventually, if a lot of interaction was made, a smoke cloud bursted in the center of the pool.

SoapBubbles Traffic Light

This project was a installation for Experimentarium in Copenhagen. This is a place for kids to come and learn about technology and science, througt experimentation and installations that shows som examples of phenomenas of physics and chemistry. The installation was used during a two-day festival with the theme Soap Bubbles.

The project was a collaboration with artist Jens Toni Willumsen, as project leader, and a bunch of other people.

PingPong Clock

This is a 7 segment display with 4 digits, I made with my friend Esben. We made it for a event called Reality Bites, which were held at Roskilde University. The event was a lecture conference about innovation and inventors, from outside the university environment. The display were used as a countdown clock for the speakers.


Here is some simple laser effects i have made for small events and private parties. They are all made from simple materials, mostly dc and servo motors, potentiometers, small mirrors, laserpointers, arduino microcontrollers and some relays.

Phono LightWall and Interactive Seat

These projects I made for the Phono Festival in Odense. Its a 2x8 m2 lightwall, placed beside the small stage at the festival, and a interactive seat placed on one of the podios used for relaxing zone.

Digital Boardgame

This was a project i made with 5 other students at HumTek, Roskilde University. It was about trying to combine traditional boardgame playing experience with the new posibilities of the computer game. This was done through a digital surface, that had the board projectet on top of it, and traditional cards and bricks known from normal board games. Tracking technology was used to feed the computer info on things happening on the board, and through text and animations, giving the players a visual overview of the games development.
To explore the actual possabilities we diden't just take a old boardgame an made i digital, but we designed a new game that was designed to use the best things from both the traditional board game and the computer game.
