Abstract

An ergonomic apparatus for generating data signals that may be indicative of alphanumeric characters for use with an electronic device or system such as a computer or electric typewriter, for example. The apparatus may be configured in accordance with ergonomic principles and use one or two hands to generate the data signals. The apparatus may include a set of domes that are shaped and contoured to conform to the shape of hands in a relaxed state and to distribute pressures across the splayed underside of the user'"'"'s hand. Each dome may be capable of movement in a plurality of directions extending radially from a home position to generate the data signal or a portion of the data signal. The two-handed implementation disclosed utilizes input movements that enable keystroke actuation via only slight arm or hand movement, no finger movement being required. A keyboard layout may be used with the domes to associate movement of each dome with an alphanumeric layout of characters on a conventional keyboard such as a QWERTY keyboard layout. Dome movement may also be associated with the relative location of alphanumeric characters on an associated keyboard and the repsective relative frequency of use of an alphanumeric character to be produced. Hand-held embodiments of the apparatus are provided that may be used with portable or other similar electronic devices.

Claims

1. An apparatus for generating a data signal, the apparatus comprising:

a housing;

a first controller moveably coupled to the housing;

an impression formed in a lower surface of the first controller defining a plurality of directions the first controller may be moved;

a first spring-loaded plunger;

a ball bearing affixed to an upper end of the first spring-loaded plunger so that the ball bearing engages the impression formed in the lower surface of the first controller for guiding the first controller among the plurality of directions;

means for sensing movement of the first controller in the plurality of directions and generating a signal indicative of a direction of movement of the first controller; and

a processing module configured to generate the data signal in response to receipt of the signal indicative of a direction of movement of the first controller.

2. The apparatus of claim 1, the means for sensing movement of the first controller in the plurality of directions and generating a signal indicative of a direction of movement of the first controller comprising a potentiometer having a pivotally extending joystick engaged with the first controller so that the joystick moves in response to movement of the first controller.

3. The apparatus of claim 2 further comprising:

a concave recess formed in the lower surface of the first controller; and

a ball affixed to an upper end of the joystick so that the ball engages the concave recess.

4. The apparatus of claim 1 further comprising:

a concave impression formed in the lower surface of the first controller; and

a second spring-loaded plunger that engages the concave impression.

5. The apparatus of claim 1 further comprising:

a second controller moveably coupled to the housing;

an impression formed in a lower surface of the second controller defining a plurality of directions the second controller may be moved;

a second spring-loaded plunger;

a ball bearing affixed to an upper end of the second spring-loaded plunger so that the ball bearing engages the impression formed in the lower surface of the second controller for guiding the second controller among the plurality of directions;

means for sensing movement of the second controller in the plurality of directions and generating a signal indicative of a direction of movement of the second controller; and

wherein the processing module is configured to generate the data signal in response to receipt of the signals indicative of a direction of movement of the first controller and the second controller.

6. An apparatus for generating a data signal, the apparatus comprising:

a housing;

a first controller moveably coupled to the housing;

a concave surface positioned on an underside of the first controller;

an impression formed in the concave surface defining a plurality of directions the first controller may be moved;

a potentiometer for sensing movement of the first controller and generating a signal indicative of a direction of movement of the first controller, the potentiometer having a pivotally extending joystick with a guide nub affixed to an upper end of the joystick that engages the impression;

means for biasing the concave surface against the guide nub; and

a processing module configured to generate the data signal in response to receipt of the signal indicative of a direction of movement of the first controller.

7. The apparatus of claim 6 further comprising:

a plurality of extensions extending from the first controller;

a base plate coupled with the first controller;

an aperture formed in the base plate; and

an insert within the aperture of the base plate wherein the concave surface is formed within the insert.

8. The apparatus of claim 7 the means for biasing the concave surface against the guide nub comprising a compression spring positioned between the first controller and the insert.

9. The apparatus of claim 6 further comprising:

a second controller moveably coupled to the housing;

a concave surface positioned on an underside of the second controller;

an impression formed in the concave surface defining a plurality of directions the second controller may be moved;

a potentiometer for sensing movement of the second controller and generating a signal indicative of a direction of movement of the second controller, the potentiometer having a pivotally extending joystick with a guide nub affixed to an upper end of the joystick that engages the impression;

means for biasing the concave surface against the guide nub; and

wherein the processing module is configured to generate the data signal in response to receipt of the signals indicative of a direction of movement of the first controller and the second controller.

10. The apparatus of claim 9 wherein the processing module is configured to generate the data signal indicative of an alphanumeric character in response to receipt of at least one of the signal indicative of a direction of movement of the first controller and the signal indicative of a direction of movement of the second controller.
