Biri-biri: Pressure Sensitive Touch Interface with Electrical Stimulation

Biri-Biri is a new touch interface system that enhances touch-based interactions by providing electrical-stimulations as feedback. The proposed system uses a low-frequency muscle/nerve stimulator combined with a pressure-sensitive touch interface covered with a conductive surface and generates pseudo-vibrations and/or electric shocks that can be felt directly in the user's finger without the need for any additional equipment.
