Tyco Electronics Japan demonstrated a new ultrasonic surface compression wave method 2-point multi-touch panel monitor using the IE Zaurus dinosaur robot created by ELO Touch Systems, a Tyco group company at CEATEC Japan 2010. IE Zaurus dinosaur robot is controlled via a 2-point multi-touch panel monitor using the 32-inch ultrasonic surface compression wave method. The ultrasonic surface compression wave method uses high-frequency ultrasound diffused across the surface, which when touched by the hand, causes interference in the ultrasonic signal that is detected to determine coordinates on the panel.
The ultrasonic method used here provides much better positioning accuracy and image visibility than infrared scanning methods. The company would like to see this technology used for remote control applications, while also promoting the technology by describing potential applications in arcade games, the medical field and digital signage scenarios.
