Granite-based touch-sensing floor for machinery safety and exergaming
Touch-sensing floor technologies are attractive due their use in several applications. Such technologies include infrared, resistive, capacitive and pressure sensing. Nonetheless, these technologies require special tiles or costly setups. For simplicity and cost effectiveness, we propose a new touch-sensing that can use granite as the touch interface. This can be achieved by utilizing the effects of extremely low frequency fields on the human body and the electrical characteristics of the granite. Using the proposed technology, granite floors can be transformed into touch-sensing floors capable of human presence detection in various applications such as machinery safety and exergaming.
