Ultrasonic waves are used in order to create pressure on the user hand when it touches a hologram. At this point only simple objects have been tried in testing, but the researchers are already planning for virtual switches at hospitals and in other areas where contamination is a worry.
I consider a new device or technology to have been culturally accepted when
it has been used to commit a murder.
