In computing, a pointing device functions by detecting two-dimensional motion relative to its supporting surface. The pointing device sometimes features other elements, such as “wheels”, which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The motion of the pointing device typically translates into the motion of a pointer on a display, which allows for fine control of a Graphical User Interface (GUI). Typically these pointing devices utilize a “point and click” sequence of moving the cursor to the desired position and depressing a button to select an action.
There are several different styles of pointing devices such as a mouse, trackball, joystick, touchpad and the like. A mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. A mouse may sometimes features other elements, such as “wheels”, which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input.
A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a cursor. Large tracker balls are common on graphical workstations for easy precision.
A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer.
A touchpad is a pointing device consisting of specialized surface that can translate the motion and position of a user's fingers to a relative position on screen. Touchpads are a common feature of laptop computers and also used as a substitute for a computer mouse where desk space is scarce. Touchpads can also be found on personal digital assistants (PDAs) and some portable media players, such as the iPod® using a click wheel.
Conventional mechanisms such as those explained above suffer from a variety of deficiencies. One such deficiency is that conventional pointing devices require a predefined amount of desk space. A further deficiency with conventional pointing devices is that the user's hands must be removed from the keyboard to use the pointing device. In addition, injuries have been recorded based on reaching an awkward distance to access the mouse or positioning the mouse at an incorrect height for ergonomic operation.
Embodiments of the invention significantly overcome such deficiencies and provide mechanisms and techniques that provide a pointing device that is controllable while the hands remain on the keyboard. In addition, the pointing device minimizes strain on wrist and shoulder while providing fast and precise positioning functions.
In a particular embodiment, a pointing device includes a central housing and a sleeve disposed surrounding a portion of the central housing, wherein the sleeve is rotatable about the portion of the central housing and wherein the sleeve is slidable along a generally horizontal axis about the portion of the central housing. The pointing device further includes a sensor disposed in the central housing, the sleeve positioned surrounding the sensor, and wherein the sensor is capable of detecting movement of the sleeve relative to the central housing. The pointing device additionally includes a circuit in communication with the sensor, the circuit capable of transmitting data to a computer regarding the movement of the sleeve.

Flexure 152 is made of a deformable material, and has a “dog-bone” shaped opening extending there through. When a user applies a downward force to the inner-sensor pointing device, flexure 152 of flexure assembly flexes, such that the parts 158 and 160 of proximity switch are brought closer together. When enough downward pressure has been applied by a user to the inner-sensor pointing device, the proximity switch (either alone or in combination with another proximity switch) detects the change in position and indicates a primary click event has occurred.
Also shown is a circuit board 156 including a proximity switch in this example is a Hall-effect device which includes a sensor 158 and a magnet 160. The sensor outputs a signal based on how close the sensor 158 is to magnet 160. The closer they are, the sensor outputs a larger voltage. Once a certain threshold voltage is reached, a primary click is determined to have happened. The sensor can be used to provide an audio feedback (e.g., a click sound) to the user to indicate a primary click operation has occurred. In this embodiment, the outputs of the sensor of proximity switch 150a and the output of proximity switch 150b are added together, and when the sum of the outputs exceeds a predetermined threshold, a primary click operation has occurred. Alternately, each proximity switch could be used independently; to determine when a right click operation has occurred and when a left click operation has occurred.

The pointing device 400 also includes a sleeve 414 which fits over a portion of central housing 412. Sleeve 414 is rotatable about a portion of the central housing, and is also slidable along a length of the central housing 412. Sleeve 414 may be supported by bushings 436a and 436b. Sleeve 414 may also include a grip.
The inner sensor pointing device 400 in this embodiment includes a sensor 430 mounted in a sensor housing 432 attached to a circuit board 416. The sensor 430 is shown as a laser sensor, though other types of sensors, including but not limited to an optical sensor or a rollerball, could also be used. A retainer spring 434 maintains the circuit board 416 within the central housing 412, in conjunction with first stud 424 and second stud 458. Also included are first end sensor 418 and second end sensor 450. A downward force provided by the user triggers pick switch 440. The amount of force necessary to trigger pick switch 440 is adjustable by operation of pick adjuster 442 in conjunction with first spring 444 and second spring 446. A cover 428 surrounds various pieces of the inner sensor pointing device.
The central housing has a printed circuit board 416 disposed entirely within. Located between the circuit board 416 and the central housing is a block 402 which is held in mechanical communication with circuit board 416 by first stud 424.
Also shown is the first end sensor 418 which includes a transmitter 420, a receiver 422 and a divider 424. In operation, the first end sensor 418 detects when the sleeve 414 has been moved so that the sleeve 414 covers the end sensor 418. When the sleeve is not covering the end sensor 418, light from transmitter 420 travels through the conical shaped cavity and passes through the opening at the distal end thereof. The light travels down to a table, desk or other support structure and is reflected back outside of the opening in the cavity. The conical shape of the cavity is defined such that the light from the transmitter is focused so the light does not reflect back into the central housing when the sleeve is not covering the central housing. As such, receiver 422 does not detect the light—therefore the sleeve is not positioned over the end sensor 418. When the sleeve 414 is moved such that the sleeve 414 covers the opening at the end of the conical cavity, the light from transmitter 420 is reflected back inside the conical cavity and is detected by receiver 422, indicating the presence of the sleeve 414 covering the end sensor 418. The divider 424 is optional and may be used to prevent the occurrence of cross talk, wherein the receiver would other-wise detect the light from transmitter 420. The end sensor 418 is shown in this embodiment as an optical type sensor. The receiver 422 could alternately be placed outside of the central housing 412 and use through-beam detection to detect when the sleeve 414 has been moved past the end sensor 418. While an optical end sensor is shown, it should be appreciated that other sensors or switches could also be used (e.g., a proximity switch, a hall-effect sensor, a capacitive switch or sensor). One advantage of using an optical end sensor is that the user doesn't feel the end of travel of the sleeve 414. The end sensor 418 provides a speed adjustment of the pointer on the display with respect to movement of the sleeve 414 about the central housing 412. Before the end sensor detects movement of the sleeve 414 past the end sensor 418, a given amount of sleeve movement correlates to a given amount of pointer movement on a display. Once the end sensor 418 detects the presence of the sleeve 414, a larger amount of pointer movement is provided for a same given amount of sleeve movement.

A pick adjuster assembly is shown, which includes a pick adjuster 442, a first spring 444 and a second spring 446. When the sleeve 414 is pressed downwardly, the sleeve 414 and central housing 412 pivot about the pivot and activate the pick switch 440. The amount of force necessary to activate the pick switch is adjustable by operation of pick adjuster 442 which is in communication with first spring 444. The first spring 444 is connected at one end to the stud which is attached to block 448, while the other end is in mechanical communication with second spring 446. The second spring 446 has a first end in communication with the first spring 444, while the other end is attached to a block. The pick adjuster 442 is movable in a horizontal direction which results in a change in the amount of force required to trigger pick switch 440. This is particularly useful when performing different operations with the inner sensor based pointing device. When a user is performing several drag-and-drop operations, it may be desirable to have the pick force set high such that elements are not unintentionally dropped while being dragged. On the other hand, when a user is performing several click type operations with little or no dragging operations, it may be desirable to have the pick force set low such that it is relatively easy to pick objects.
In another embodiment the pointing device is comprised of a hollow tube having a sleeve disposed surrounding a portion of the tube, wherein the sleeve is rotatable in part about at least a portion of the tube and wherein the sleeve is slidable along a generally horizontal axis about the portion of the tube. The pointing device further includes a sensor disposed along a surface of the tube, the sleeve positioned surrounding the sensor, and wherein the sensor is capable of detecting movement of the sleeve relative to the tube.
In still another embodiment, the pointing device includes a central housing having an aperture, the central housing having a generally tubular form and a sleeve disposed surrounding a portion of the central housing, wherein the sleeve can concurrently (i) rotate about the portion of the central housing and (ii) slide along a generally horizontal axis about the portion of the central housing. The pointing device further includes a sensor disposed in the central housing and aligned with the aperture, the sleeve positioned surrounding the sensor, and wherein the sensor is capable of concurrently detecting (iii) rotational movement of the sleeve relative to the central housing and horizontal movement of the sleeve relative to the central housing. Additionally, the pointing device includes a circuit in communication with the sensor, the circuit capable of transmitting data to a computer regarding the rotational movement and horizontal movement.
In a particular embodiment, a mode referred to herein as “power scroll” can be entered. When the sleeve is at or near the end of travel on one side or the other of the central housing, a power scroll mode is entered, wherein the sleeve can be used as a scroll wheel to quickly scroll through a document. Moving the sleeve away from the end of the central housing results in exiting the power scroll mode.
