2-D Glasses: Watch 3-D Movies Without The 3-D

Many people complain of headache and uneasiness when watching 3-D movies.

If you are one of them, Hank Green an inventor has a special pair of glasses for you.

Mr Green hit upon the novel idea that one could easily convert 3-D video into 2-D by simply blocking light from one of the two overlapping images.

When his wife confessed that she gets headaches when watching 3D movies, the happy-to-help Mr Green repurposed the 3D glasses by swapping polarising filters and created the world’s first 2D glasses.

Mr Green’ 2-D glasses look like 3-D glasses, only they have the same polarization in each lens, which effectively strips away the 3-D and leaves a 2-D image for you to enjoy without developing a headache. You can buy a pair of these glasses for $8.

3D Sound From Ordinary Speakers

Edgar Choueiri, a professor of mechanical and aerospace engineering, has developed a way to play true three-dimensional sound recordings over regular loudspeakers, such as those found in computer laptops and televisions.

In one demonstration, two microphones were placed on a dummy’s head who is made to sit in a conference table with several other people.

The recorded sound from the two microphones were played back through two ordinary speakers - after processing them using Choueri's 3D filter - in another room where the listener is.

The listener was able to correctly locate the position of each speaker.

The technique may one day be used to allow 3D televisions to produce lifelike sound and to help people with certain types of hearing impairments locate noises.

A 2GHz Smartphone by 2012 by Samsung

Smartphones are becoming ridiculously powerful. 

Samsung, which will soon release a 1.2GHz dual-core version of its Galaxy S smartphone, is not resting on its laurels. The company  promised we’d see a 2GHz Samsung smartphone by next year. Mashable cites a “high ranking Samsung official” who confirmed plans for a 2GHz mobile phone CPU during a conversation with the Maeli Business Newspaper.

"We are planning to release a 2GHz dual core CPU-equipped smartphone by next year. This product will have the data processing capacities of a regular PC," the official said.

Samsung is said to be considering selling the chips separately to third party manufacturers.
Samsung's 1.2GHz Galaxy S2 is set for a May launch in the United Kingdom. The North American release for this device has yet to be announced.

Control Your PC Using Your Eyes

Called the Tobii PCEye, the gadget is primarily designed for customers with limited motor skills or spinal injuries this USB device allows the user to control a PC by eye movement.

Users can control their entire computer through gazing, blinking or dwelling on an item with their eyes.

Like an old-school webcam, the Tobi PCEye mounts on the bottom of an LCD panel and connects to the PC via a USB port.

Although the company didn't get into the details on how the device actually works, Tobii said that its eye tracking technology can effectively track nearly every user (over 95-percent) regardless of eye color, lighting conditions, environments or head movement. Tobii also said that its track box (explained as the box defining the area/volume in which a person's eyes can be tracked) is one of the largest on the market.

"The Tobii PCEye won’t slow down your computer, or restrict you from staying up to date with technology," the company said.
