Be AMAZED with this Tangible and Visible 3D Shapes In Mid Air.

Impossible as it may seem but with the aid of Haptic Technology these 3D SHAPES that can be seen and felt are certainly plausible. Let’s findout why!

Every pings and vibrations of your smartphone as you tap different keys and the rumble of your Wii controller as you smash a tennis ball are both examples of haptic effects.



From the Greek word “haptikos”, meaning able to grasp or perceive.  Haptic sensations are created in consumer devices by actuators, or motors, which create vibrations.

However, this touch feedback breakthrough has uses that are far beyond enhancing your game experience. It is utilized as a rehabilitation tool for stroke patients. Recently, scientists have invented a new method of haptic feedback using focused ultrasound, which creates 3D haptic shapes in mid-air that can be seen and felt.

Researchers predicted that this innovative technology could transform the way that we use 3D haptic shapes. It could lead to touchable holograms to boost learning or improved gaming experience by allowing users to feel the features of the game, such as a simple ball. It could even have a place in medicine, for example by allowing surgeons to physically feel tumors by exploring CT scans, Hence, Haptics provides a more realistic experience of performing both medical and gaming procedures.

Amused? But wait, there’s more.

A method for creating three-dimensional haptic shapes in mid-air using focused ultrasound applies the principles of acoustic radiation force, whereby the non-linear effects of sound produce forces on the skin which are strong enough to generate tactile sensation and scattering acoustic waves. Through behaviors of sound waves, it is extremely possible to infer the shape of the object whenever they hit an object.

Other than that, in order to feel the shapes in our bare hands, the researchers have created air disturbances that could be felt on the skin and could be seen as floating 3D shapes. Although, the ultrasound patterns cannot be seen by themselves, the examiners visualized them by directing the device into a layer of oil so that depressions at the surface appeared as several ‘spots’ when lighted up.

With the addition of invisible 3D shapes to 3D displays, the creation of a tangible and visible 3D objects takes place in a free space.

In the 21st Century this advanced technology can allow people to feel holograms of objects that are considered impossible, such as feeling the images of the CT scan or understanding the shapes of artifacts in a museum.
