Tablet
A pressure sensitive input device used in conjunction with a pen to edit digital images.

Touch-screen
A display monitor that is pressure sensitive to touch and is often used as a multimedia control instead or in conjunction with a keyboard. Better authoring systems should have touch-screen interface functions built in their software. Touch-screen displays vary widely and can be accomplished with special overlays or can come as integral screens with built-in touch-screen capabilities. The best screens also feature z-axis control, which allows screen response at different rates depending on the level of pressure applied.

Track
A sequence of contiguous data, the beginning, length, mode and end of which are defined in the table of contents, which is held in the Q subcode channel of the lead-in area of the disc. The two types of tracks currently defined are the CD-DA track according to the CD-ROM specification that is also used in CD-I. In CD-DA the length of a track is related to playing times between four seconds and 72 minutes.

Tuning
The Group term for a number of image editing activities including color and grey balancing, hue & saturation, gamma, histogram, and contrast adjusting…etc.
