What if you could actually change sound levels in a night club without touching any buttons? <br /><br /> British company Ultrahaptics has developed a technology that uses ultrasound to allow people to ‘feel’ and interact with 3D virtual objects by projecting them through the air directly onto the hands.<br /><br /> Researchers say it works by applying the principles of acoustic radiation force – whereby sound waves produce strong tactile sensations.<br /><br /> Professor Sriram Subramanian, co-developer of the project explained more: “If you go to a night club or a rock concert, you feel the music in your chest. And it’s the same principal – you feel the sound vibrating your chest.”<br /><br /> “Instead of using the bass sounds, what we use is low frequency ultrasound – about 40 kHz – and that way we can target it at a precise point on your finger tip or on your palm, and then you feel the palm vibrate and it feels precise as well.”<br /><br /> Although the technology is still in the prototype stage, researchers believe it has a div
