Patent Images
1. A computer terminal user interface control comprising:
- a first force-sensitive transducer pair defining a first force sensitive axis;
a second force-sensitive transducer pair defining a second force sensitive axis;
means for aligning the first and second force-sensitive transducer pairs such that the first force sensitive axis and the second force sensitive axis are disposed at an angle relative to one another; and
a data processor including means for positioning the cursor on an associated video display terminal at a position relative to a default position in accordance with force applied to at least one transducer of the first and second transducer pairs;
wherein the cursor includes tools adapted to be activated by a second cursor generated by a second pointer controller.

Abstract
A computer terminal user interface control is provided for allowing input from an operators non-dominant hand. Force sensitive resistor pairs are provided at right angles to one another. Forces applied to these transducers move a tool set to various sub-portions of a video display device. The user'"'"'s dominant hand is then free to select from various sub-areas of the tool window positioned by the non-dominant hand in a simple and efficient manner.

10. A method of two-handed computer user interface control comprising the steps of:
-
receiving a tactile force from a non-dominant hand of an associated computer operator into a first force-sensitive transducer having a bidirectional first force sensitive axis; receiving a tactile force from the non-dominant hand of the associated computer operator into a second force-sensitive transducer having a bidirectional second force sensitive axis disposed generally orthogonally to the first force sensitive axis; generating an analog signaling in accordance with force applied to each of the first and second force-sensitive transducers; generating, via an analog-to-digital conversion unit, digital signaling corresponding to the analog signaling; receiving the digital signaling from the analog-to-digital conversion unit; positioning a video window of an associated video display relative to a default position in accordance with the digital signalling; communicating digital pointer data received from a pointer positioned next to a dominant hand of the associated operator; and receiving operator selection of a subportion of the video window in accordance with a position of the pointer within the video window. - View Dependent Claims (11)

12. A pointing device comprising:
-
a first force-sensitive transducer means defining a first force sensitive axis for generating a first signal corresponding to any sensed axial force therealong; a second force-sensitive transducer means defining a second force sensitive axis for generating a second signal corresponding to any sensed axial force therealong; a base portion adapted to be rigidly secured to an associated desktop, the base portion rigidly securing each the first and second force-sensitive transducer means thereto such that the first and second force sensitive axis are angled relative to one another; a handle portion movably disposed relative to the base portion such that induced movement of the handle portion induces corresponding force to at least one of the force-sensitive transducer means; means for generating a digital cursor control signal in accordance with at least one of the first and second signals, whereby the digital control signal corresponds to force induced on any of the force-sensitive transducer means by application of force to the handle portion; and means for communicating the digital cursor control signal to an associated graphical user terminal. - View Dependent Claims (13, 14, 15)
