An important part of this exploratory behavior consists in the feedback obtained, generally of acoustic and tactile nature. Humans, from their birth onwards, are characterized by a strong tendency to explore the space surrounding them. The Need for Sensing Technologies in Cognitive Research We foresee using these devices for a range of cognitive experiments.ġ.1.
We successfully pilot tested the first device with a group of chimpanzees.

Acceleration data is sent via Bluetooth to a computer running Max/MSP. A second prototype consists in a modified Wii Remote contained in a gum toy. Strain data is sent to a computer running Python through an Arduino board. One prototype uses four piezoelectric elements embedded between layers of Plexiglas and foam. The prototypes differ in sensing technology, costs, intended use and construction requirements. We present two prototypes we developed for application with chimpanzees ( Pan troglodytes) which, while fulfilling the aforementioned requirements, allow to arbitrarily associate sounds to physical object movements. Specifically, no device exists which simultaneously allows: (i) spontaneous production of sound or music by non-human animals via object manipulation, (ii) systematical recording of data sensed from these movements, (iii) the possibility to alter the acoustic feedback properties of the object using remote control. However, no device or solution is currently available, with the use of sensors in non-human animals being almost exclusively devoted to applications in food industry and animal surveillance. The possibility of achieving experimentally controlled, non-vocal acoustic production in non-human primates is a key step to enable the testing of a number of hypotheses on primate behavior and cognition.
