Projection keyboard

A projection keyboard is a virtual keyboard that can be projected and touched on any surface. The keyboard watches finger movements and translates them into keystrokes in the device. Most systems can also function as a virtual mouse or even as a virtual piano. A proposed system called the P-ISM will combine the technology with a small video projector to create a portable computer the size of a fountain pen.

How a projection keyboard generally works:

1. A laser or beamer projects visible virtual keyboard onto level surface
2. A sensor or camera in the projector picks up finger movements
3. detected co-ordinates determine actions or characters to be generated

Some devices use a second (invisible infrared) beam:

1. An invisible infrared beam is projected above the virtual keyboard
2. Finger makes keystroke on virtual keyboard. This breaks infrared beam and infrared light is reflected back to projector
3. Reflected infrared beam passes through infrared filter to camera
4. Camera photographs angle of incoming infrared light
5. Sensor chip determines where infrared beam was broken
6. detected coordinates determine actions or characters to be generated

FULL-HD 3D with 3D Eyewear Included

FULL HD 3D makes you feel as if you'd stepped out of your living room and into the world on the screen. The viewing experience has never been so lifelike and compelling.The technology in which the left-eye and right-eye 3D images are sent to the viewer is the key to 3D image quality. For this, FULL HD 3D uses something called the Frame Sequential technology. A separate 1920 x 1080 full-HD image is sent to each eye. This addresses the image quality problems and blurring which is common to previous 3D systems, and creates sharp, crisp 3D images.

Infinite Black Pro with Dynamic Contrast 5,000,000:1

A contrast ratio of 5,000,000:1 enables VIERA to display extremely robust blacks. A new panel and improvements to the cell discharge area dramatically increase contrast when viewing in brightly lit locations. And reducing the electrical pre-discharge that causes greying has greatly enhanced black gradation. As a result, deep, rich blacks are displayed in virtually any viewing area, from living rooms to bedrooms. Even in dark film scenes, clothing textures and individual strands of hair are clearly reproduced.

VIERA CAST with Skype

Enjoy Internet content right on your TV. With VIERA CAST technology, you can enjoy online content such as videos, photos, weather and stock information through an easy-to-use Web interface that's built into the TV. Other services are also becoming available, one after another, such as "tweeting" web communications via Twitter™ and home video and audio conferencing with Skype™. In addition, VIERA CAST provides USB terminals for a USB Keyboard and Communication Camera. No PC required.

600Hz Sub-field Drive

600Hz technology lets you view superb full-HD motion and still images with 1,080 lines of resolution. For even greater clarity with motion images, Panasonic uses its own unique image-analysis technology. This technology converts the motion in each scene into data. And each frame is practically displayed for a shorter length of time than in previous systems, to reduce aftereffects. *When using Cinema mode

THX® Certified Display

THX reproduces film images exactly as the film's creators intended them. The overall aim was to improve the experience of cinema-goers and faithfully recreate the audio and visual ambience that filmmakers intended. To receive THX certification, TVs undergo stringent tests to determine, for example, whether the exact same brightness and colour are displayed at all screen locations, and whether black levels satisfy standard criteria. VIERA meets the high standards set by the THX Certified Display Program.
