PreVue (Credit: Melody Shiue)

PreVue is currently just a concept. It's unclear how exactly Shiue suggests the device will operate. The most likely way is via some sort of advanced ultrasound. The problem is that current ultrasound technology is a far cry from what can be seen in the images Shiue depicts, especially when it comes to special resolution and details (color also does not exist although it might be possible to add it in software).

 

Ultrasound technology had advanced considerably  in recent years both in terms of size, price, and to some degree, quality. However it will be a few years at least before it will reach the level needed to allow for the creation of the PreVue. As for the flexible display, Shiue’s idea is to use electronic textiles. Other options include a form of bendable electronic paper or bendable OLED display, but we suspect that the display technology will be ready far before the ultrasound unit.

 

TFOT covered several advances in ultrasound technology including how ultrasound-activated microbubbles fight cancer, a more portable ultrasound device, and an interesting article on ultrasound helmets which control brain activity.
