Keyboard is something that comes to our mind the moment we think of a computer. Now technology advancement has turned keyboard virtually by means of an amazing piece of technology. Virtual keyboard is a technology that allows the user to operate by moving fingers on a wireless or optical surface or an area instead of the actual physical keys. The keyboard is projected optically on a flat surface and as we touch the image of the buttons, the stroke made becomes detected by the optical device and sends it to the computer. Sometimes short range Bluetooth technology is used for optical device to transmit the signal wireless. The benefit of the virtual keyboard being the portability, accuracy, reduces the strain to the finger and can be also used along with the smart phones.

The world’s smallest hard drive for computer is less than an inch is size. Toshiba has released a hard drive that weighs only 2 grams and measures a length of only 0.85 inch. This small size hard disc posses the capability of having a memory of 8GB with all the features that are included in an ordinary hard drive. This hard disc has also entered the Guinness Book of World Records for being the smallest hard drive ever created. Now this technology comes with external storage hard drive. A HD-DVD drives with writeable mode is a first ever feature that is available along with this hard disc for both desktops and laptops. This technology is going to new computers very smaller.

Wireless USB is a high bandwidth, short range wireless protocol that is used in the radio communication. Wireless USB is sometimes called as WUSB or certified wireless USB. It works on the basis of the Ultra Wide Band (UWB) that is a common radio platform. The data sending capability of the wireless USB is about 480Mbit/s within a distance of 3 meters and 110Mbit/s within 10 meters. WUSB is designed to be operational in 3.1 to 10.6GHz frequency range. However this range may vary depending the country because of their legal regulation policies. Wireless USB will soon replace the wired cables from the peripherals of the USB. WUSB are much more advantageous than Wi-Fi when compared with their operating frequency range.

The computing device that used to select navigate through computer content is called as an optical trackball. The optical trackball looks like it has a stationary base, a protruding ball housed in a socket, and one or more buttons that allow the user to perform the functions of clicking.  Very rarely some optical trackball also contain a scroll wheel for ease of scrolling through web pages and text documents. The ball portion which at the top of the optical trackball is covered with dots arranged in a pattern. As the user handles the ball with his fingertips, IR optical sensors read the movement of the dots and then send the data to the computer. This feature may allow for a more precise tracking of movements, since non-optical sensors simply read the rotation of the ball on only two axes.

DiamondTouch is a new generation tabletop touch screen that was developed first by the Mitsubishi Electric Research Labs. It was later licensed to the Circle Twelve Inc recently. This technology has the feature of multi touch along with many new advanced benefits that are not included in the other touch computers. These DiamondTouch Table has unique capability of allowing multiple people to touch simultaneously at the same instant and identifies where each person has touched. The touch made on the screen is identified as a stroke and converted in to data that will be differentiated by means of a unique way to be produced in the desktop. This new technology will cause rise in new revolution of computers and laptops.

A multi touch screen drivers was released by Dell for the latitude XT tablet. This was clamed as the industries first ever convertible tablet along with the feature of multi touch capabilities. This multi touch capability was made as a combined release with N-trig a multi touch technology startup for its tablets. It includes a dual digitizer used of low pressure and high touch accuracy. Excellent connectivity can be done with the new wireless LCD based antenna. You can all the natural gestures like rotating, panning scrolling the web pages that are larger, more advanced zooming for clear viewing of the graphics and many more. The future with multi touch on XT2 will make you forget the use of touchpad and keyboards.

Many people use different kinds of tools like audio recorder to take down lectures and notes so that they don’t miss out any thing. For a video conference a headphone is necessary for convenience. This means a versatile tool necessary for different desired application. What if a computer in the size of pen with the entire features that you want is available? Now a pen type computer with the advantage of writing, sound recording and sound listening with a microphone has been invented. It also includes analog to digital converter and a sound generation device. Where the process of conversion of sound into analog signal and then into digital signal for the process of storing the data. During the time of listening the processor does the reverse process to convert data into sound.

Blue ray discs are used to store data’s, record songs, store movies and many more with high definition video quality and increased space storage. Blue ray technology offers more than five times the storage capacity of the older DVDs. Its offers storage in two layers. Each layer can store up to 25GB, so the total storage capacity would be 50GB. Now 20 layered blue ray discs are also available which would have a storage capacity of 500GB. Traditional DVDs use simple red layer to write and read data but blue ray rely on the blue –violet laser. The advantage of the blue laser is that the wave length is much shorter than ordinary red laser. This helps to focus on the thinner spots for higher precision. As a result tighter storage of data can be done.

A brain gate converts your brain activity into computer commands. There a sensor is used to sense the brain activity which is implanted in the brain using neuroprosthetic and the electrodes are hooked together from the brain to the pedestal on the scalp. An optical fiber connected carriers the brain activity to the computer, so what ever we think appears in the computer. There are bundles of one hundred wires that are made out of gold and kept connected to the pedestal, which in turn extends through the scalp. The signal processing software algorithm that gets the stored data from the brain and analysis the electrical activity of the neurons for conversion. The converted control signal can be used in various computer applications. This technology would be gift to people who are completely paralyzed due to illness or trauma.

Have you ever dreamed of having a computer in your pocket? Now by means of the advancement is the growth of technology miniature computer that are portable enough to carry in your pocket is available. Blue tooth is made use to transfer data in these miniature computers, so within short area due to the presences of high bandwidth effective transmission is done. A pen type displaying device is used to project the monitor image in the wall and the keyboard in a flat surface. By means of the wireless technology hand gesture made on the keyboard image will converted into data and displayed on the screen. In the forthcoming years you don’t have to carry a laptop where ever you want to go.
