Star Trek's holodeck takes a step closer to reality: Scientists create system that allows people to FEEL holograms using ultrasound
The system uses sound waves focused on an area above the device
Air disturbances created by the waves create the feeling of 3D objects
These can be combined with 3D displays to create a 'haptic hologram'
It could have practical applications, such as allowing surgeons to explore a CT scan by enabling them to feel a disease

A Star Trek-style holodeck could be closer to reality following the creation of a system that lets people feel holograms with their bare hands.
The system projects 'haptic holograms' into mid-air, allowing users to feel what they are seeing using vibrations in sound waves.
As well as its use in entertainment, the technology could have more practical applications, such as allowing surgeons to explore a CT scan by enabling them to 'feel' a disease.

The method, developed by Dr Ben Long at Bristol University, uses ultrasound focused on an area immediately above the device.
By focusing complex patterns of ultrasound, the air disturbances can be seen as floating 3D shapes.
