Two-Handed Keyboard

Two-Handed Keyboard

Most GUI applications are centered on using only the dominant hand for pointing and manipulation of objects on the desktop. But in real life, many actions are more easily accomplished with both hands. The Two-Handed TrackPoint gives you two pointing devices embedded in your keyboard. Some applications of Two-Handed pointing are:

Drawing

Detailed work is done on a drawing with the dominant hand; selecting tools with the other. Manipulating pixels with the dominant hand; selecting colors with the other. Drawing rectangles and other shapes by manipulating both corners at once.

Text

Selecting text with the dominant hand; modifying its style with the other. Positioning the cursor with the dominant hand; scrolling around the document with the other. Windowing: Rapidly selecting between two windows by keeping one cursor in each. Marking text in one window and pasting it in another.

This simple extension of TrackPoint technology has the possibility of speeding many user-interface tasks.
