Wearable computers a smart fashion trend

A woman tries Google Glass during the Google I/O developer conference on May 17, 2013. A wearable computing trend is at the heart of the "quantified self" movement in which people track anything from how many calories they burn to how well they sleep.

Audi Launches Car-Shaped Computer Mouse

Audi has launched a cool new PC mouse in the shape of an Audi car. Sure an interesting and innovative idea!

According to the German car maker, the Audi mouse is an ideal mix of sportiness, sophistication and progressiveness. The Audi mouse is both, Windows and Mac compatible. The mouse comes with 2.4 GHz technology. At the bonnet is centered the scroll wheel and the mouse comes with high-resolution 2000dpi sensor with a minimum range of 6meter.

According to Michael Perschke, head of Audi India, “Now, Audi enthusiasts will not only drive their favourite luxury brand to work, they can have it on their work stations too and manoeuver their PC in style with a wireless computer mouse based on Audi cars. It has a sleek design and is luxurious from the first touch. Suitable for home or office, this delightful computer mouse lets you drive your computer or laptop by truly displaying the brand's philosophy.”

Acer Aspire R7

Acer Aspire R7, the Windows 8 laptop that has a "floating touchscreen" that can be twisted, spun, flipped, and moved every which way.

The hinge gymnastics only really work because the R7's display is so good. It's a 15.6-inch 1080p panel with 10 fingers of multitouch support, and it's accurate and vivid from any angle – viewing angles are crucial on a device you'll use in so many configurations, and Acer gets it right here. The screen is also blindingly bright, with 40 percent brightness more than serving my needs.

Charger

An 18-year-old Indian-origin girl in the US has developed a potentially revolutionary device that can charge a mobile phone in just 20 seconds, a media report said.
The charging device has been dubbed a 'supercapacitor' by Esha Khare of Saratoga, California, the Daily Mail reported. Khare won $50,000 for her invention at the Intel International Science and Engineering Fair, held in Phoenix.
Khare has only used her 'supercapacitor' to power a light-emitting diode (LED), but says that one day her invention will power cell phones, cars and any gadget that requires a rechargeable battery.

 

Asked what inspired her to work on the technology, Khare said, "My cell phone battery always dies. It has a lot of different applications and advantages over batteries in that sense."
The 'supercapacitor' is flexible and tiny, and is able to handle 10,000 recharge cycles, more than normal batteries by a factor of 10. Khare is a student of nanochemistry, and is now heading to Harvard.

Transparent smartphone to debut by the end of 2013

London: In a revolutionary development, a Taiwanese company claims to have developed a gen-next transparent mobile phone which it says will be in the market by the year end. The company, Polytron Technologies, has already begun marketing a transparent multi-touch phone. Its prototype uses a 'Switchable Glass' technology.
That is a conductive Organic light-emitting diode (OLED) using liquid crystal molecules to display images, the 'Daily Mail' reported.
When the phone is in off mode, the molecules align to form a milky composition, but when switched on they re-align to form text, icons, and other images. Electric current is carried through transparent wires.

The device still contains some parts that are not transparent, including a SD card and SIM card. The microphone, camera, and batteries are also visible, and will be hidden behind a dark glass cover when the model goes into production.
The company, will develop a smaller lithium ion battery that would be much less noticeable. When complete, the phone will have a dual-sided multi-touch display in front and back.
The prototype phone has yet to feature any software or operating system, the report said. A Japanese company recently used a transparent liquid crystal display (LCD) in its wristwatch but had trouble adding hardware to the smaller frame.
"The challenge of using a transparent display in a wristwatch, and I suppose other wearable technology, is that you need to store the batteries somewhere else (usually they are stored behind the LCD panel)," Tokyoflash marketing manager Paul Cooper said.
It remains to be seen whether the phone's transparency by itself will attract buyers, as the prototype does not offer significantly different functions than most smartphones.
