"Frisporet is a color-tracking device that through audio-feedback facilitates a vision impaired person to jog with no need of help from another person. The only thing they need is Frisporet."

The project was made in collaboration with Sebastian O'Sullivan HĂžjholm & Kristian Hovgaard Simonsen.

About the design process & the project
We chose vision-impaired people as our user group. At first, we simply started a dialog with a group of vision impaired persons to get insights about how it is to be vision impaired and what kind of difficulties it might bring. We soon realized that most of them talked about freedom. A freedom related to their physical environment around them and their body movements. We asked how they exercise and how it relates to freedom. They said that most of the time they need someone with vision to guide them e.g. when running. This meant that their freedom almost always is bound to another person. We wanted to free them from this boundary. That's why we came up with the idea to make "Frisporet". In the following period we invited the user group to several workshops through which we iterativly developed our prototype.

The prototype of our project was made with MAX MSP, a computer in a bag, a webcam and headphones. Basically, the computer in the bag runs our MAX MSP-code which uses the input of the chest-mounted webcam to track any color of your choice. This way of color-tracking is very sensitive which means that the prototype only works with a special-painted running track with a centered unique-colored line. This colored line is the one that the prototype tracks. If the runner differs too much to either of the sides our code will read off the input of the webcam and send an audio-feedback through the headphones to the runners appropriate ear depending on runners position in proposition to the colored line. If the runner differs to the right side of the line the audio-feedback appears in the right ear and vice versa.
