Play games with mindreading headset



This will bring huge revolution in the continuously evolving game industry.

This is one of the applications of BCI (Brain Computer Interfacing). This device work by sensing the impulses in brain that are responsible for different actions like blinking, concentration etc. This is a good advance in BCI but still we have a long way to go in reading human thoughts.

Heliodisplay

Heliodisplay is a display technology which projects the 2D, 3D images into mid-air. It doesn’t require any solid medium for projecting the images, thus images can be available anywhere.

The inventor of Heliodisplay is Chad Dyner, who once quited his job to do something different. He wanted to become an inventor and had put his full concentration in transforming air to a movie screen. This eventually led to Heliodisplay around the year 2000. After his invention, he founded IO2 Technology in San Francisco, Bay Area and obtained the legal patent on Heliodisplay.

Dyners Heliodisplay is just like a digital projector with a chip(micromirror system) containing millions of tiny mirrors that would tilt back and forth to create the images. A fan is used to create a sheet of air that reflect the light projected by the micromirror system. This is just a gist about the working of Heliodisplay, however the exact method is still patented Dyner.

In 2005, the U.S. Patent Office granted Dyner a patent for a "method and system for free-space imaging display and interface". Apparently, the Heliodisplay creates a particle cloud by passing the surrounding air through a heat pump, which in turn cools the air to a level below its dew point, where it condensates, and is then collected to create an artificial cloud. The particle cloud is composed of a vast number of individual micro droplets, between 1-10 microns in diameter, too small to be visible to the naked eye, held together by surface tension. The focus and illumination intensity of the projected image can be controlled by changing some of the cloud's properties, enabling a sharper and brighter image.

Here is a video of Heliodisplay from youtube.

Heliodisplay systems, from IO2 Technology, have been deployed by some of the world's largest companies, such as automobile firms, defense contractors, as well as by governments and universities.
