3D Ultrasound That Can Be Felt

[Swifty]

(from Focus Science and Technology Magazine)

Researchers at the University of Bristol have come up with a 'haptic' system that can create touchable shapes using ultrasound. By focusing complex patterns onto a user's hand, the device produces a 3D shape that can be felt in mid air. The technology could enable surgeons to explore a CT scan by touch, enabling them to feel a disease such as a tumour, say the scientists.

This is quite interesting:

Scientists change monkey minds using low-intensity ultrasound

An incredible new study suggests that low-intensity ultrasound can be used to target very specific brain regions and alter an animal's decision-making processes. The technique, demonstrated in macaques monkeys, prompts actual behavioral changes using non-invasive ultrasound waves.

"Interesting" as in "disturbing? I can't imagine what brought them to this experiment, what good could come of it if the tech progresses in leaps and bounds? Never thought tinfoil hats would become the new season's must-have fashion accessory.

I find that to be a worrying experiment.

Isn't there already some sort of loud/deep sound device used for crowd control or have I imagined it?

Just answered my own question :fslap:

It's scares me too.
