As part of the Invisible Architectures Festival (2011, Newcastle, UK), the project Sandstone Echo invited participants to a tactile sound walk. Wearable devices worn on the index finger were able to sense vibration when touching a surface.
The sensors were connected to a smart phone. When the wearer touched an object, the vibration of was conducted to the sensor through the bone, and from there brought forward to the smart phone. A simple code processed the information and transformed it into a sound feedback, which was directly played back into headphones worn by the participant. The menu allowed changing the sounds, varying from abstract single tone feedback to musical sample players. Depending on the material and surface roughness of the touched object, the sound feedback varied in strength, such as volume, distortion and pitch.
