Touch Screen Activates Without Touching -Tony Stark Way
Tony Stark,uses ultrahaptic device to activate touch screen without actually touching it physically.Stark uses his hands to interact with this high-tech interface. With an ultrahaptic device,ultrasound transducers create sound waves at a high frequency.These waves create isolated changes in air pressure that mimic the sensation of touch. No contact with a physical object is necessary. A research team at the University of Bristol recently demonstrated the working of the system with a display that projects the sound waves. A user interacts with items on the display by using his hands several feet above it, but he feels as if actually touching the display as vibrations reach the fingertips. By changing that vibration, the team discovered that they can create different sensations, making the air the user is touching feel like it has texture, and even creating the sensation of raised areas and edges.
