Abstract

Disclosed is a pointing device to provide data input to a computer in accordance with the direction and magnitude of forces applied to a low-displacement point stick. The pointing device, being mounted in a housing separate from the keyboard of a computer, can be positioned by the system user to optimize comfort and productivity.

Separate Pointing Device with Low-Displacement Data Input

      Disclosed is a pointing device to provide data input to a
computer in accordance with the direction and magnitude of forces
applied to a low-displacement point stick.  The pointing device,
being mounted in a housing separate from the keyboard of a computer,
can be positioned by the system user to optimize comfort and
productivity.

      Fig. 1 is an isometric view of a first version of the pointing
device, in which the pointing stick 1 is mounted to extend through an
opening in the left side of a housing (2).  The depression of buttons
(3) provides the input functions normally associated with the buttons
of a conventional computer mouse.  This version facilitates operation
of the pointing stick (1) by means of the right thumb, while the
buttons (3) are operated by fingers of the right hand.  A left-handed
version of the device of Fig. 1 has a pointing stick mounted to
extend through an opening in the right side of the housing.

      Fig. 2 is an isometric view of a second version of the pointing
device, in which the pointing stick (4) is mounted to extend through
a hole in the top of a housing (5).  This version facilitates
operation of the pointing stick (4) by a finger of either hand, while
buttons (6)  on opposite sides of the housing (5) are operated by the
thumb and a opposing finger of the same hand.

      In either the version of Fig. 1 or the version of Fig. 2, the
pointing stick (1,4), which is mounted rigidly at an inner end
opposite its outward-extending tip, provides the X- and Y- input
functions normally associated with the movement of a computer mouse.
The X- input value is derived from a load-sensing device, such as a
strain gage or force-sensing resistor within the housing (2,5) bonded
to a first side of the pointing stick (1,4) so that the application
of a force to the tip of the pointing stick in a direction indicated
by arrow (7) in Fig. 1 or by arrow (8) in Fig. 2 produces an
electrical output.  The Y-input value is derived similarly derived
from a load-sensing device bonded t...
