Have
you heard of haptic technology?
Scientists have invented a new method for
creating three-dimensional haptic shapes in
mid-air using focused ultrasound which
creates 3D haptic shapes that can be seen
and felt. This approach applies the
principles of acoustic radiation force. Its
everywhere, for instance the buzzing of your
smart phone or the vibration rumble of your
Wii controller are both haptic
effects. it’s used in surgical
training and for rehabilitation of stroke
patients.
Based at the University of Bristol,
Researchers foresee that this innovative
technology could transform the way that we
use 3D haptic shapes. Touchable
holograms to augment learning, or for gaming
experience, allowing users to literally feel
the game, such as a baseball, soccer,
football, and more.
The method, exploits an effect produced by
ultrasound called acoustic radiation force,
which is the scattering and absorption of
the acoustic wave. It is possible to deduce
the shape of the object. By focusing complex
patterns of ultrasound onto our hands, it is
possible to feel the shapes. The researchers
created air disturbances that could be felt
on the skin and seen as floating 3D
shapes.
“Touchable holograms, immersive virtual
reality that you can feel and complex
touchable controls in free space, are all
possible ways of using this system,” lead
author Dr. Ben Long said in a news release.
“In the future, people could feel
holograms of objects that would not
otherwise be possible, such as feeling the
differences between materials in a CT scan
or understanding the shapes of artifacts in
a museum.”
