A projector mounted above the surface provides context to the shapeshifting pins, giving them color and highlighting depth. In a video released by MIT, the table is shown moving a ball, mirroring a book, displaying 3D charts, and giving an extremely visible smartphone notification.
Technology has changed rapidly over the last few years with touch feedback, known as haptics, being used in entertainment, rehabilitation and even surgical training. New research, using ultrasound, has developed an invisible 3-D haptic shape that can be seen and felt.
The research paper, published in the current issue of ACM Transactions on Graphics demonstrates how a method has been created to produce 3D shapes that can, be felt in mid-air.
The research could change the way 3D shapes are used. The new technology could enable surgeons to explore a CT scan by enabling them to feel a disease, such as a tumour, using haptic feedback.
When Chip Yates started working on his electric airplane in 2012, he wasn't trying to make conventional, gas-powered aircraft look slow. That hasn't changed, he says. "That was not the design goal."
But he's happy to point out his plane is as fast or faster than its competitors that run on single piston gas engines. The five world records Yates set last year for electric planes were finally officially verified by the Fédération Aéronautique International (FAI) last week, and now he can officially claim bragging rights.
