Little Helpers incorporate an ultrasonic sensor and a motor with Arduino resulting in a simple way to make environments more interactive –
Bodies moving through a space trigger motors, sounding whatever object they are attached to. Movements acquire a resonant trace. The use of movement as a trigger is intended to initiate performative engagement, drawing passersby into interactive exchange and making audible the impact of their movements upon their immediate surroundings.
