PYGMY robot rings, according to the researcher, are made to enhance the interaction experience between humans and gadgets and to express emotions.
PYGMY robot rings can be remotely controlled via special controller or by a smartphone application. The rings are made in various sizes with each containing an Arduino processor, Bluetooth, and battery.
These eye like robotic rings were demonstrated at Interaction 2012 Conference last week in Tokyo. The researcher deems his application of the technology can be used in teaching environment.
