Abstract

A method to enable mouse pointing devices to provide depth/force (Z-axis) information is described. Sensors in the form of strain gauges or spring-loaded wheels are added to the mouse pointing device to provide Z-axis information, which supplements the X- and Y-axis information provided by standard devices.

Depth Force Capability for Mouse Pointing Devices

      A method to enable mouse pointing devices to provide
depth/force (Z-axis) information is described.  Sensors in the form
of strain gauges or spring-loaded wheels are added to the mouse
pointing device to provide Z-axis information, which supplements the
X- and Y-axis information provided by standard devices.

      Additional sensor(s) are added to a mouse so it can provide
force/depth (Z-axis) information.  There are at least two ways to do
this.

      The first is to use a strain gauge (which measures force) as
the sensor.  The sensor (or two) could be added under the standard
mouse keys, either replacing the click function or being activated
past the click point.  The sensor could instead be added to an
additional key for fingers or palm on the top of the mouse.  The user
would press with the palm of the hand or, for instance, the middle
finger, or the sensor could be connected to additional keys on the
side(s) of the mouse for the thumb and/or gripping fingers.  In this
implementation, the user "squeezes" the mouse to indicate depth.  As
a possible cost reduction, simple mechanisms would allow a single
strain gauge to be accessed by both side keys.

      Another method is to use a roller or wheel placed somewhere on
the mouse as the sensor.  The user would roll forward to move
"deeper" on the screen and backward to move to the "front" of the
screen.  This kind of sensor would benefit from...
