Aspect Ratio: The ratio of horizontal pixels to vertical pixels in a display device. Most normal TVs and monitors are in a 4 : 3 aspect ratio. Widescreen TVs and monitors are typically in a 16 : 9 aspect ratio, the same as movie theatres.

Bass Boost: Deepened bass that lets you feel more of the action.

BBE Sound: Audio processing technology used in the FMD-700 Eye-Trek that corrects distortion and phase delay in the audio signal. This gives the audio a great "live presence." BBE is a registered trademark of BBE Sound Incorporated.

Component signal (Y Cb Cr): A connection / cabling standard for carrying a video signal. Component cabling carries separates the signal into luminance and two color differentials allowing for the cleanest possible picture.

Composite: The connection / cabling standard for carrying an NTSC video signal. Composite cabling carries all video information (luminance, chrominance, synchronizing, and blanking) at the same time on the same cable.

Delta Pattern: The pattern in which the pixels on a LCD screen are arranged. Behind the pixels is a black matrix. If the pixels were lined up horizontally and vertically, the viewer may notice a faint black grid on the screen. To prevent this, the pixels are staggered. This is known as a Delta Pattern.

Face Mounted Display(FMD): Head Mounted Displays often must be attached using a headband due to their bulky size and weight. The Eye-Trek is designed to be so small and lightweight that it can be comfortably mounted on the face, just like a pair of glasses. With this, it is known as a Face Mounted Display.

FOV (Field of View): The horizontal and vertical angle at which an image is viewed. In the case of the Eye-Trek, it is the FOV angle of 30 degrees that creates the image of a 52-inch screen from 6.5 feet away.

Free Shaped Prism: Highly developed optical technology used in the Eye-Trek Face Mounted Displays. The prism successfully creates a large image from a small screen while keeping it clear and virtually distortion free. See Innovations that are Exclusive to Olympus for more detailed information.

Head Mounted Display: Display mounted on the head, usually using a combination of a headband and a brow pad.

High Eye Point Design: Innovative design of the Eye-Trek that allows for a gap between the Eye-Trek and one's eyes. This allows the unit to be worn comfortably with a pair of glasses.

High-Performance Optical Filter: Reduces visibility of black pixel matrix for a smooth, sharp image.

Letterbox: A picture with the wider dimensions of a movie theater screen as opposed to the more square standard television screen.

LCD: Liquid Crystal Display. A screen that uses color changing, voltage sensitive, liquid crystals to display an image. LCD's are typically flat paneled and often used for portable applications.

NTSC: Stands for National Television Standards Committee. NTSC is typically used to describe the video standard in the United States and Japan.

Optical Filter: The process of using optics to "shift" the pixels on a LCD screen onto the black matrix behind them. This, along with a Delta Pattern arrangement of the pixels, greatly reduces the coarseness of the image.

OSR: Optical Super Resolution. This is the highly advanced optical processing system that is used in the FMD-700 Eye-Trek. It effectively quadruples the resolution if an image through high-speed pixel shifting and digital processing. See Innovations that are Exclusive to Olympus for more detailed information.

Pixels: Picture Elements. The tiny dots of color and light that compose a digital image.

Refresh Rate: The amount of times a display renews itself in one second.

Resolution: The fineness of detail that can be distinguished in an image, as on a video display terminal. It is usually indicated by a vertical / horizontal pixel count (ex. 640x480).

See Around Design: Innovative design of the Eye-Trek that allows one to maintain their peripheral vision while remaining engaged in the audio-visual experience. One can eliminate this by using the optional side and full visors, resulting in a more immersive, theatre-like experience.

SRS Sound: Sound Retrieval System three-dimensional audio used in the FMD 250W Eye-Trek. The technology retrieves the spatial information from any stereo recording and restores the original three-dimensional sound field. Created by SRS Labs, Inc.

S-Video: A connection / cabling standard for carrying an NTSC video signal. S-Video cabling keeps the luminance and chrominance video signals separate, allowing for a cleaner overall picture.

Surround Sound: Sound technology that distinguishes sounds not only from left to right, but also from front to back.

VGA: Stands for video graphics array. VGA is a graphic display system for PCs. Most modern monitors and video cards correspond to the 15-pin VGA standard.
