Two-Handed TrackPoint

Most GUI applications have 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 into your keyboard. Horizontal Trackpoints, vertical Trackpoints, Trackpoint in the corner are examples of ways to make ambidextrous Two-Handed point for Internet mice and doing scrolling and pointing at the same time.

Some applications of Two-Handed pointing are:

• Drawing:
  • Detailed work on the 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.
  • CAD work using one pointer to grab tools and the other to use tools.
• 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.

Software to make 300 applications work across platform and on all applications has been constructed to work with the Two-Handed TrackPoint in the keyboard. This simple extension of TrackPoint technology has the possibility of speeding many user-interface tasks.
