Abstract

Disclosed is an apparatus for making extensive use of the thumb(s) in entering data and control movements. The apparatus forms an ensemble of controls contoured and placed for easy use by the thumb(s) on any hand-operated or hand-held input, control or data entry device, including keyboards, keypads, wheel controls, stick controls, or hand- held devices such as, but not limited to, telephones and remote control units. The control ensemble includes a protrusion and/or surface contoured for use by a thumb and/or one or more keys sized and contoured for thumb use. The control action and control gain characteristics are appropriate for the thumb, and suitable for both ballistic and fine-grain movements. The control ensemble is positioned on the entry device in a location where the thumb normally resides for that device.

Thumb Control Ensemble for Data-Entry And Control-Entry Devices

       Disclosed is an apparatus for making extensive use of the
thumb(s) in entering data and control movements.  The apparatus forms
an ensemble of controls contoured and placed for easy use by the
thumb(s) on any hand-operated or hand-held input, control or data
entry device, including keyboards, keypads, wheel controls, stick
controls, or hand- held devices such as, but not limited to,
telephones and remote control units.  The control ensemble includes a
protrusion and/or surface contoured for use by a thumb and/or one or
more keys sized and contoured for thumb use. The control action and
control gain characteristics are appropriate for the thumb, and
suitable for both ballistic and fine-grain movements.  The control
ensemble is positioned on the entry device in a location where the
thumb normally resides for that device.  In the example illustrated
in the figure, the control is positioned where the thumb(s) rest on
the keyboard.  On other data-entry or control devices, the thumb
control ensemble is located for convenient use by the thumb(s).

      The thumb control addresses problems with conventional entry
devices that recently have arisen stemming from the addition of
function to controls.  The additional function requires users to move
their hands back and forth between different areas of the control
ensemble, and also requires users to move their eyes between the
display and the control...
