Pen Input Device with Tactile Feedback

      A method is described for providing positional guidance to the
user of a pen-based system, through the tactile sense.

o   The tactile sense is used with a pen-based system to allow the
    user to write and keep track of his position on a tablet without
    requiring constant visual attention.

o   A small linear motion device is built into the pen shaft, which
    moves a short distance along the axis of the pen.  Each time the
    pen reaches the edge of a bounding line, comb field, or other
    input guides, the linear motion device clicks to the end of its
    motion range.

      A small linear motion device is built into the pen shaft, which
moves a short distance along the axis of the pen.  This device is
entirely enclosed within the pen.  It may, for example, be
implemented via a small solenoid, a piezo-electric device, or a
voice-coil motor.  This device is activated under software control.

      Each time the pen reaches the edge of a bounding line, comb
field, or other input guides, the linear motion device clicks to the
end of its motion range.  When the pen leaves the edge (by
backtracking, or by crossing it), the motion device returns to its
normal position.

      The tactile effect, caused by this very slight motion of the
mass within the pen, gives the user the impression of "bumping into"
or running over the guide lines, as if the surface had raised or
engraved guide li...
