Abstract

Two pedals are used together to control a computer cursor. A Sensitivity Pedal (Pedal 2) varies the sensitivity of the cursor and a Movement Pedal (Pedal 1) determines directional movement. By using both feet dynamically together, greater speed and precision is possible than with one foot alone. Cursor movements can be achieved which are both fast and precise, yet are still within the comfortable range of foot movement, by starting with maximum sensitivity then reducing the sensitivity as the target position is approached. Mouse-clicks are generated by rotational movement of the Sensitivity Pedal.

Description

FOOT-OPERATED CURSOR CONTROLLER Description This invention relates to a foot-operated computer cursor controller.
Modern computer interfaces generally include a cursor, by which the user can indicate specific areas or points on the screen before (or sometimes after) selecting from a range of command inputs. Cursor control is commonly achieved with a mouse, operated by one hand. The mouse and hand are normally at the side of the keyboard, forcing the operating arm to be abducted and so creating the possibility of overuse injuries in the neck and shoulder muscles. Also the user has to move the hand off the keyboard in order to move the cursor, then back again in order to enter text or keystroke commands: this is an inefficient process.
Other known cursor controllers govern the acceleration ofthe cursor rather than its position, and so are slow to use, or have limited resolution or precision.
The present invention provides fast precise foot control of the cursor position. The invention comprises two controls, of which one determines directional movement and the other varies the sensitivity of he cursor to those directional control inputs.
Some specific embodiments of the invention will now be described by way of example, with reference to the accompanying drawing.
Example \
Referring to the drawing, the Movement Pedal 1 is operated by the user to move the cursor from its current position towards the desired position. The Sensitivity Pedal 2 affects the extent of the resulting cursor movement: when the Sensitivity Pedal is only slightly depressed, small precise cursor movements result from Movement Pedal inputs so that individual pixels may readily be selected; when the Sensitivity Pedal is fully depressed, large fast movements result so that any part of the screen is accessible with a single actuation ofthe Movement Pedal. Thus a cursor movement can be achieved which is both fast and precise, yet is still within the comfortable range of foot movement, by starting with maximum sensitivity then reducing the sensitivity as the target position is approached. The two controls are used dynamically together.
Pedal movements in both axes of the Movement Pedal and in the up-down axis of the Sensitivity Pedal are sensed by conventional opto-electronic mouse components. Clicks are sensed by non-latching switches.
When the Sensitivity Pedal is not depressed, the Movement Pedal does not move the cursor at all. This is a means of allowing the Movement Pedal to be re- positioned without moving the cursor, and is in this way equivalent to lifting the mouse off the mouse-mat.
The Movement Pedal can be moved both up and down and from side to side, rotating about a pivot at the heel end. When the pedal is moved (while the Sensitivity Pedal is depressed), the cursor moves in the direction of pedal movement: down the screen when the pedal is depressed, up when the pedal is allowed to lift; towards the left of the screen when the pedal is rotated anti¬ clockwise (left), towards the right of the screen when the pedal is rotated clockwise (right). These pedal movements can be made simultaneously in both axes, to give direct linear cursor movement to any point on the screen.
When depressed the Sensitivity Pedal initiates then increases sensitivity of the cursor to inputs from the Movement Pedal. With only slight depression sensitivity is low, in order to facilitate precise cursor positioning, whereas with full depression sensitivity is very high for fast cursor movements across the screen. The effect is progressive, so that when partly depressed a moderate sensitivity is given. The Sensitivity Pedal is so mounted or designed as to enable a rocking action from side to side when the user's foot is inverted or everted. Switches are actuated when the pedal is so rocked, which give the functions of mouse-button clicks. When the left side ofthe pedal is pressed downwards, a Left mouse- button click is given, and when the right side ofthe pedal is pressed downwards, a Right mouse-button click is given (these clicks can optionally be swapped over Left to Right and Right to Left in software as is normal for a mouse). The clicks can be felt and /or heard to confirm operation.
The pedals can be positioned independently of each other, so that according to preference a user may use the left foot to operate the Movement Pedal and the right foot to operate the Sensitivity Pedal, or vice-versa.
Example 2
As Example 1, but the mouse-button functions are given by rotating the Sensitivity Pedal to left and right in the horizontal plane instead of rocking it. Thus both pedals move in the same ways.
Example 3
As Examples 1 or 2, but when attached to a computer designed for only a single mouse-button, both sides ofthe Sensitivity Pedal generate the same button-click.
Example 4
As Examples 1, 2 or 3, but when the Movement Pedal is moved without pressure under the heel, no cursor movement results, so that the pedal may be re- positioned without moving the cursor - this is analogous to lifting a conventional mouse off the mouse-mat. In this example, the Movement Pedal moves the cursor with low sensitivity even when the Sensitivity Pedal is not depressed. Example f>
The signals from the two pedals are made available separately to the computer, so that their interaction can be varied or switched off in software. This enables software to make specific use of the pedals, such as brake and accelerator simulation for games.
Example f.
As any preceding example, but pedal movement in one or more axes is sensed by electromagnetic induction.
Example 7
As any preceding example, but pedal movement in one or more axes is sensed by a linear voltage displacement transducer.
Example 8
As any preceding example, but pedal movement in one or more axes is sensed by a potentiometer.
Example 9
As any preceding example, but pedal movement in one or more axes is sensed by an optical transmission transducer.
Example 10
As any preceding example, but both pedals move in all three axes - up/down, side-to-side, and edge-to-edge rocking. All signals are processed in software according to the specific application.
Example 11
As any preceding example, but the interaction ofthe pedals is determined in hardware or firmware. The signal delivered to the computer is compatible with a mouse signal, and is treated as such by the computer and its software. Example 12
As any preceding example, but one or both pedals pivot around a point forward of the heel, and do not move when the foot is removed.
Example 13
As any preceding example, but one or both pedals pivot around a point forward of the heel, and return to an intermediate position when the foot is removed.
