"description": "A six-inch square transducer board is mounted to the table. A monitor behind it shows bubbles rising and popping. The Ultrahaptics transducer board emits ultrasonic audio waves, a sound frequency inaudible to the human ear but perceptible on the skin. Sound waves become a tactile interface. This innovative technology is created by Ultrahaptics, located in Bristol, United Kingdom.",
"instructions": "Place your hand about ten inches above the board.\n\nFeel the sensation of ultrasonic audio waves against your skin.\n\nThe image on the screen reinforces the effect.",
