Wearable technology can help with public speaking

Wearable technology can help with public speaking

March 30, 2015

Speaking in public is the top fear for many people. Now, students and faculty from the Human-Computer Interaction Group have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, and have made the tool freely available for downloading.

Laser-etched metal bounces water

Laser-etched metal bounces water

January 21, 2015

Physicists in the US have created metal surfaces that repel water to the extent that droplets bounce away. They sculpted the surface of small pieces of platinum, titanium and brass using a very high-powered laser. The materials “self-clean” because water droplets gather dust particles before they slide away.

Scientists make metal surfaces water-repellent

Scientists make metal surfaces water-repellent

January 20, 2015

Two University of Rochester scientists have found a way of using powerful laser beams to make metal surfaces last longer and be more suitable for a wide range of practical purposes. “We change the nature of the metal surface so that they can repel water,” said Chunlei Guo, who is a professor of optics and physics at UR.

The real life cloaking device is here and you can buy it

The real life cloaking device is here and you can buy it

January 12, 2015

Scientists at the University of Rochester invented an actual cloaking device that will make objects disappear.
This is not a joke. You can buy a cloaking device for $49. The catch? It’s not wearable. The cloaking device consists of a series of four lenses that bend light around 3D objects so they appear invisible.

There is now an IRL invisibility cloak you can make for $50

January 9, 2015

How about an IRL Invisibility Cloak? No, seriously, someone invented it. OK, so its not exactly a cloak. Its more like a series of four lenses that keep objects hidden from multiple angles. But it exists, it works and its kind of amazing.
