IMG_1017.jpeg

Description:

A set-up named "Groene vingers" demoing the Makey Makey board by utilising soil as a conductive material to switch between between two images. The switching and image handling is done within Isadora.  

Required components:

  • 2 trays
  • Computer with Isadora (Isadora patch via this link)

Order from input to output:
- The 2 trays with earth cform the + and - of a circuit, which is closed when a person places both hands on it.
- The Makey Makey sensor board detects when the circuit is closed and sends the letter 'g' as a keyboard command.
- the 'g' key activity is detected in Isadora and used to fade between projections of photos, film and text and to start a sound.
- Using the projection mapping (a.k.a. video mapping) function in Isadora, the images are projected in the correct perspective and within the frames of the trays.
