New Ultrasound Technology Lets Users See and Touch 3D Shapes in Thin Air
Haptics, or touch feedback technology, has changed rapidly over the course of the past few years. Now, the Bristol Interaction and Graphics group has developed technology that can create an invisible 3D haptic shape using ultrasound, which can be both seen and felt.
The research paper, which has been published in the current issue of ACM Transactions on Graphics, describes how a new device sends out complex patterns of ultrasound waves. By focusing the ultrasound waves and creating air disturbances, the device creates haptic feedback in mid-air. The system also generates an invisible 3D shape.
In other words, the new device is a projector that can create floating, 3D shapes, which can also be touched.
The researchers believe that this new device could change the way people use 3D shapes...
