Touch and feel virtual objects
British experts have developed a technology that uses sound waves to create
British experts have developed a technology that uses sound waves to create a "forced field" that can reproduce the feel of touching real objects in the air.
Researchers at the University of Bristol say that the "super-tactile" system uses a series of speakers to create ultrasound waves aligned to create an invisible vibration wall in the air, computer picture.
This wall can be used to feel like touching a real object that is actually displayed.
The new system creates a "tactile" wall to add a sense of responsiveness to the action in front of the screen.
Placed behind a screen, the system tracks the movement of the user's finger across the screen, and creates a tactile feedback layer as they interact with virtual objects such as door knobs and switches. gas.
'By creating instant feedback points and tapping them, users can receive feedback on their feelings related to their actions,' the Guardian quoted them as saying. computer scientist Tom Carter.
The system allows the user to define different tactile characteristics without having to touch anything in the real world.
Systems such as Microsoft's Kinect sensor can track the user's hand and body movements, allowing them to interact with a computer interface, but lack tactile feedback.
Carter says his team's goal is to integrate tactile feedback into these systems without sacrificing their superiority of simplicity and ease of access.
