• Resumen

  • Imagine waving one's hand in front of a map on his computer screen and feeling a force push back against him. The strength of the force could be proportional to the population or crime rate, say, of each city he passes over. Tom Carter and his colleagues at the University of Bristol in UK, will demonstrate just such a system at the User Interface Systems and Technology conference in St Andrews. Called UltraHaptics, it uses an array of 320 ultrasound speakers set behind a touchscreen to generate beams of high-frequency sound waves.
