Pointing Device Based on Internal Sensor CROSS REFERENCE TO RELATED APPLICATIONS The present invention claims priority from U.S. Provisional Patent Application No. 61 / 267,616, filed December 8, 2009, which is incorporated herein by reference in its entirety. The present patent application is divided from the Swedish patent application with number 1051293-7, filed on December 8, 2010.
BACKGROUND In computer technology, a pointing device works by detecting two-dimensional motion relative to its support surface. The pointing device sometimes has other elements, such as "wheels", which enable the user to perform various system-dependent actions, or extra buttons or features that can add more control or dimensional input. The movement of the pointing device is usually translated into the movement of a pointer on a display, which allows fine-tuning of a graphical user interface (GUI, "Graphical User Interface"). These pointing devices typically utilize a point-and-click sequence with moving the cursor to the desired position and pressing a button to select the event.
There are different types of pointing devices, such as a mouse, trackball, joystick, touchpad and the like. A mouse is a pointing device that works by detecting two-dimensional motion relative to its support surface. A mouse physically consists of an object held under one of the user's hands, with one or ﬂ your buttons. A mouse can sometimes display other elements, such as "wheels", which enable the user to perform various system-dependent actions, or additional buttons or features that can add additional control or dimensional input.
A trackball is a pointing device consisting of a ball carried by a holder 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 hand to move a cursor. Larger trackball units are common on graphic workstations for easy precision.
A joystick is an input device consisting of a rod that is articulated on a base and reports its angle or direction to the device it controls. J oystic devices are often used to control video games and usually have one or ﬂ your pushbuttons, which states can also be read by the computer.
A touchpad is a pointing device consisting of a specialized surface that can translate the movement and position of a user's fingers to a relative position on the screen. Touchpad devices are commonly found on laptops and are also used as a replacement for a computer mouse, where the desktop space is limited. Touchpad devices can also be found on personal digital assistants (PDAs) and some portable media players, such as the iPod® that uses a click wheel.
SUMMARY Conventional mechanisms such as those described above suffer from various shortcomings. One such shortcoming is that conventional pointing devices require a predetermined desktop space. A further shortcoming of 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 due to the need to extend an impractical distance to reach the mouse or place the mouse at an incorrect height for ergonomic use.
Embodiments of the invention significantly overcome such shortcomings and provide mechanisms and techniques that provide a pointing device, which can be controlled while the hands remain on the keyboard. The pointing device also minimizes the load on the wrist and shoulder, while providing fast and accurate positioning functions.
In a particular embodiment, a pointing device comprises a central housing and a sleeve which is arranged so as to surround a part of the central housing, where the sleeve can be rotated around said part of the central housing and where the sleeve is slidable along a substantially horizontal axis about said part of the central housing. The pointing device further comprises a sensor arranged in the central housing, the sleeve being positioned so as to surround the sensor, and where the sensor is capable of detecting for movement of the sleeve relative to the central housing. The pointing device further comprises a circuit which is connected to the sensor, the circuit being capable of transmitting data to a computer regarding the movement of the sleeve.

DETAILED DESCRIPTION Referring to Figure 1, a first embodiment of a pointing device 10 is shown. The pointing device 10 includes a central housing 12. The central housing 12 contains additional parts, which are discussed in detail below. The pointing device 10 also includes a sleeve 14 which is fitted over a portion of the central housing 12. The sleeve 14 is rotatable about a portion of the central housing, and is also slidable along a length of the central housing 12. The sleeve 14 is supported by bushings 18a and 18b. . The sleeve 14a includes a grip 16. The central housing 12, the sleeve 14, the bushings 18a and 18b and the grip 16 comprise a roller assembly, which is described in detail below. Furthermore, parts 26a and 26b of a housing are shown as the support roller assembly. A palm rest 28 is also shown.
Figure 2 gives a view with a transparent casing of the roller assembly and the casing. Switches 30a, 30b and 30c are displayed. Here the switches are shown as quick switches, but other types of switches (eg proximity switches) could also be used. The switch 30a is used to detect downward movement of the roller assembly and the holder, when a user presses down on the roller assembly to initiate an action or event referred to as a "mouse click". As described below, the holder and the roller assembly are movable with respect to the base. The switch 30a can also be referred to as a pick switch ("picksWitch"). The click action detected by the pick switch 30a can, for example, be used to perform a drag and drop action with the pointing device in the graphical user interface (GUI) of a computer.
The switches 30b and 30c are limit switches (also known as limit switches) and are used to detect when the sleeve 14 has reached the end of its possible horizontal movement along the central housing 12 in either a left direction (switch 30b) or a right direction (switch 30c).
Referring to Figure 3, the holder and roller assembly are shown. The holder 24 includes end pieces 22a and 22b. The end piece 22a includes a pivot pin 32a, and the end piece 22b includes a pivot pin 32b. The pivot pins are fitted in holes in the base and allow for movement of the holder and the roller assembly with respect to the base.
Figure 4 shows the roller assembly. The roller assembly includes a central housing 12. The central housing 12 contains additional parts, which are discussed in detail below. Furthermore, the visa sleeve 14 is fitted over a part of the central housing 12. The sleeve 14 is rotatable around a part of the central housing, and is also slidable along a length of the central housing 12. The sleeve 14 is mounted on the central housing 12 by bushings. 18a and 18b, which allow the rotation and sliding movement of the sleeve with respect to the central housing. While the central housing 12 is shown as substantially tubular in the drawings, the central housing may also include shapes having a substantially circular cross-section; a cross-section having at least one flat surface and at least one curved surface, and a cross-section having at least three rounded corners.
Referring to Figure 5, a cross-sectional view of a section of the roller assembly is shown. A sensor 40 is located within the central housing 12. The sensor 40 is shown as a single laser sensor, although other types of sensors, including but not limited to a single optical sensor or a roller ball, could also be used. Furthermore, an opening 42 is shown in the central housing 12, through which the sensor 40 can detect movement of the sleeve 14 with respect to the central housing. The sensor 40 is therefore aligned with the aperture42. Control means, for example in the form of at least one electronic circuit, are arranged to be in communication with the sensor 40 and are capable of transmitting data regarding the detected movement of the sleeve 14 to a computer. The data transmitted may act as summer driver control signals for use in a graphical user interface (GUI) of the computer. This data may be transmitted over a suitable wired (eg serial, such as USB) or wireless (eg Bluetooth) interface to the computer. The control means is also advantageously arranged within the central housing 12. In some embodiments, the control means may comprise first circuit which is connected to the sensor 40 and is arranged within the central housing 12, and a second circuit which is arranged outside the central housing 12. In such an embodiment the first circuit may have the task of receiving and interpreting the detected sleeve displacement from the sensor 40 and transmitting this data to the second circuit. The second circuit may have the task of sending the displacement data to the computer. In addition to data relay sleeve detection, detected by the sensor 40, the controller may also transmit data detected in the pointing device 10, such as, for example, data regarding a click action detected by the aforementioned pick switch (30a).
Referring to Figure 6, a cross-sectional view of an end portion of the roller assembly is shown. A limit switch 50 is shown mounted within the central housing 12 and carried by a single switch holder 58. The switch 50 is mounted on a circuit board 52. The switch 50 in this example is a mechanical switch and includes a piston 54. The piston 54 is in mechanical connection with a bumper 56. In use, when the sleeve extends near the end of the central housing, the sleeve will engage the bumper 56, which will drive the piston 54 into the switch 50.
In a certain embodiment, a mode can be entered which is referred to here as "effect scrolling". When the sleeve is at or near the end of its path of movement on one or the other side of the central housing, a power scrolling mode enters, where the sleeve can be used as a scroll wheel to quickly scroll through a document. By moving the sleeve access from the end of the central housing, it exits the power scroll mode.
Referring to Figure 7, another embodiment of a pointing device 110 is shown. The pointing device 110 includes a central housing 112, which includes two pieces 112a and 112b removably attached to each other. The central housing 112 contains additional parts, which are discussed in detail below. The pointing device 110 also includes a sleeve 114 which is fitted over a portion of the central housing 112. The sleeve 114 is rotatable about a portion of the central housing, and is also slidable along a length of the central housing 112. The pointing device 110 communicates with a computer or the like. device through a cable 116.
Figure 8 shows a sleeve 114. In one embodiment, the sleeve 114 is flexible and made of plastic, fabric, paper, rubber or similar material, the sleeve corresponding to the shape of the central housing when installed to surround a portion of the housing. In another embodiment, the sleeve is made of a hard material. The sleeve may be provided with a mark printed on it, and the sleeve may be replaceable for one user, the user replacing one sleeve with another sleeve.
Referring to Figure 9, a central housing 112 is shown. In this embodiment, the central housing 112 is constituted by two pieces, a top piece 112a and a bottom piece 112b, which are removably attached to each other. The central housing 112 contains the sensor 140, which is capable of detecting the displacement of the sleeve with respect to the central housing 112. The central housing also includes the circuit for communicating data from the sensor to the computer.
Referring to Figure 10, the pointing device 110 is shown as including a base which is comprised of two parts 120a and 120b. The base supports the central housing 112 so that the sleeve 114 can move around the central housing.
Figures 11-13 show some of the internal components of the central housing 1 12. Internal components not shown in these views include a sensor, a circuitry at least one switch. Referring to Figure 11, a section of the central housing is cut through. The sleeve 114 surrounds the upper part of the central housing 112a and the lower part of the central housing 112b. Furthermore, springs 122a and 122b are shown.
The springs 122a and 122b bias the upper portion of the central housing 112a away from the lower portion of the central housing 112b, leading to a gap 130 between the two portions of the central housing 112. A screw 124a holds the two parts of the central housing together. . The gap 130 allows the top part to be depressed and can activate a switch (not shown).
Referring to Figure 12, the central housing is shown in section through. The sleeve 114 surrounds a section of the upper portion of the central housing 112a and the lower portion of the central housing 112b. Furthermore, springs 122a and 122b are shown. The springs 122a and 122b bias the upper portion of the central housing 112a away from the lower portion of the central housing 112b, leading to a gap 130 between the two portions of the central housing 112. Screws 124a, 124b and 124c hold the two portions of the central the casing. The gap 130 allows the top part to be depressed and activate a switch (not shown).
In a particular embodiment, one switch is arranged in the vicinity of the screw 124b and another switch is arranged in the vicinity of the screw 124c. The switch in the vicinity of the screw 124b can be activated when a user presses down the end of the section 112a of the central housing in the vicinity of the switch to emulate the event when a user right-clicks on a conventional mouse button. Similarly, the switch in the vicinity of the screw 124c can be activated when a user presses down the end of the section 112a of the central housing near the switch to emulate the event when a user left-clicks on a conventional mouse button.
Referring to Figure 13, an exploded view of the pointing device 110 is shown. The sleeve 114 surrounds the upper portion of the central housing 112a and the lower portion of the central housing 112b. Furthermore, springs 122a and 122b are shown. The springs 122a and 122b bias the upper portion of the central housing 112a away from the lower portion of the central housing 112b, leading to a gap between the two portions of the central housing 112. Screws 124a, 124b and 124c hold the two portions of the central housing. The gap 130 allows the top part to be pressed down and activate the switch (not shown). Furthermore, base pieces 120a and 120b and a cable 116 are shown.
Referring to Figures 14a to 14c, various views of bending assemblies 150a and 150b are shown. As shown in Figure 14a, each end of the pointing device includes an internal sensor net and a bending assembly, respectively. The pointing device with internal sensor is supported by the bending units 150a and 150b. Downward pressure applied by a user to the pointing device with internal sensor causes the bending unit to register a "primary click", similar to a 10 left mouse click on conventional mouse units. The down pressure can be applied at any position on the pointing device with internal sensor and will be registered.
Referring to Figures 14b and 14c, a view of the bending assembly 150a is shown. In this embodiment, the bend assembly 150a includes a bend 152 which is anchored to a base (not shown) by a fastener (e.g., a screw) 154. The fastener anchors one end of the bend to the base, while the remainder of the bend assembly 150 carries the remainder of the pointing device. with internal sensor.
The bend 152 is made of a deformable material and has a "dog bone-shaped" opening extending through it. When a user applies one-way force to the pointing device with internal sensor, the bend 152 in the bending assembly follows, so that the parts 158 and 160 of the proximity switch are moved closer to each other. When sufficient downward pressure has been applied by a user to the internal sensor pointing device, the proximity switch (either alone or in combination with a proximity switch) detects the change in position and indicates that a click action, such as a primary click event, has occurred.
Furthermore, a circuit board 156 is shown including a proximity switch, in this example hall effect device which includes a sensor 158 and a magnet 160. The sensor emits a signal based on how close the sensor 158 is to the magnet 160. The closer they are to each other, the greater the voltage emitted by the sensor . As soon as a certain threshold voltage is reached, it is determined that a primary click has occurred. The sensor can be used to provide an audio feedback (for example, a click sound) to the user to indicate that a primary click action has occurred. In this embodiment, the output signals from the sensor in the proximity switch 150a and the output signal from the proximity switch 150b are added together, and when the sum of the output signals exceeds a predetermined threshold value, a primary click action has occurred. Alternatively, each proximity switch could be used independently; to determine when a right-click action has occurred and when a left-click action has occurred.
Referring to Figures 15a-b, an embodiment of a pointing device 200 containing a pair of leaf springs 202a and 202b is shown. The roller assembly, which includes the central housing 12, the sleeve 14, the bushings 18a and 18, is supported by leaf springs 202a and 202b, which are located near the ends of the central housing 12. When a force is applied by the user in a substantially downward direction of the spring spring blade, . The downward movement triggers one or ﬂ of your switches which indicates that the "click action" is in progress. This click action may, for example, be used to perform a drag and drop action with the pointing device. A typical downward force (also referred to as "picking force") to effect the click action is generally 50 to 111 grams of force, although this can be adjusted to achieve an optimal required force. As shown in Figure 15b, a lobe 204 is used. to perform the picking power adjustment.
Referring to Figures 16a-d, an embodiment of a pointing device 210 containing a pair of solenoids 214a and 214b is shown. Each solenoid 214a and 214bin includes a respective piston 2l8a and 2l8b, coil 220a and 220b and piston return spring 222a and 222b. The roller assembly, which includes the central housing 12, the sleeve 14, the bushings 18a and 18b, is supported by the solenoids 214a and 214b, which are located near the ends of the central housing 12 and are in mechanical communication with the leaf springs 212a and 212b. When a force is applied by the user in a substantially downward direction to the roller assembly, the solenoid piston (s) are deflected, and so do the leaf springs' Foch 222b. The amount of force required can be adjusted by leaf spring force adjustment 224. The downward movement triggers one or ﬂ your switches, indicating that a click action is in progress. Figure 16d also shows a cover 216, which surrounds parts of the hardware in the pointing device with an internal sensor and protects the parts from dust, dirt, moisture and the like and also provides various alternative circuit diagrams. Various covers and various switch arrangements can also be included.
Referring to Figures 17a-b, there is shown an embodiment of a pointing device 220 with an internal sensor, containing a pair of leaf springs 222a and 222b. The roller assembly, which comprises the central housing 12, the sleeve 14, the bushings 18a and 18, is supported by «in the leaf springs llggnoch g), which are located near the ends of the central housing 12. When a force is applied by the user in a substantially downward direction on the roller assembly, the leaf spring frame bends off. The downward movement triggers one or more of the switches 224a and 224b (located outside the roller unit), which indicates that a one-click action is in progress.
Figures 18a and 18b show a further embodiment, which comprises a keyboard keyboard 302 with an integrated sensor pointing device 304. The embodiment shown in Figure 18a is attached over a desk or a stand, while the embodiment shown in Figure 18b is attached under a desk or stand. A keyboard 306 can be placed on the keyboard tray 302 and adjacent the pointing device 304. The keyboard tray is mechanically connected to a desk or stand by a keyboard tray arm 308 which allows the keyboard tray 302 and the pointing device 304 to be placed at a user-optimal position.
Figures 19a and 19b show a further embodiment comprising a keyboard keyboard 302 with a pointing device and wrist support assembly 312. The pointing device and wrist support assembly 312 includes a pointing device 314 and a wrist support 316. The embodiment shown in Figure 19a is attached while a desk or stand is mounted over a desk. Figure 19b is attached under a desk or stand. A keyboard 306 may be located on the keyboard tray 302 and adjacent the pointing device and wrist support assembly 312. The keyboard tray is in mechanical communication with a desk or a stand through a keyboard tray arm 308 that allows the keyboard tray 302 and the pointing device 304 to be placed in an optimal position.
Referring to Figure 20a, a first embodiment of a pointing device 400 is shown. The pointing device 400 includes a central housing 412. The central housing 412 includes additional parts, which are discussed in detail below. While the central housing 412 is shown as substantially tubular in the drawings, the central housing may also include shapes having a substantially circular cross-section; a cross section having at least one flat surface and at least one curved surface; and a cross section having at least three rounded corners.
The pointing device 400 also includes a sleeve 414 which is fitted over a portion of the central housing 412. The sleeve 414 is rotatable about a portion of the central housing, and is also slidable along a length of the central housing 412. The sleeve 414 can be mounted with bushings 43 6a and 436b. The sleeve 414 may also include a grip.
The internal 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, although other types of sensors, including but not limited to an optical sensor or roller roller Could also be used. A retaining spring 434 holds the circuit board 416 within the central housing 412, together with a first pin 424 and a second pin 458. A first end sensor 418 and a second end sensor 450 are also included. A user-provided downward force triggers the pick switch 440. The amount of force required to trigger the pick switch 440 is adjustable by operating a pick adjuster 442 together with a first spring 444 and a second spring 446. A housing 428 surrounds various parts of the pointing device with an internal sensor .
Figure 20b depicts a cross-sectional view of a left portion of the pointing device 400a with internal sensor. The central housing 412 has an opening that allows that central housing to rest on a pivot pin 426. When the sleeve 414 is pressed downward, the sleeve 414 and the central housing 412 are rotated about the pivot pin 426 to emulate the event when a user performs a "primary" click action, similar a left click on a conventional mouse button. 13 This click action can, for example, be used to perform a drag and drop action with the pointing device. A typical downward force (also referred to as a "picking force") to accomplish the click action is usually 50 to 120 grams of force, although this ceiling is adjusted by a user to provide an optimum required force.
The central housing has a printed circuit board 416 which is arranged completely within it. Between the circuit board 416 and the central housing a block 402 is located, which is kept in mechanical connection with the circuit board 416 through a first pin 424.
Further shown is the first end sensor 418 which includes a transmitter 420, a receiver 422 and a divider 424. In use, 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 does not detect the end sensor 418, light travels through s the cone-shaped cavity and passes through the opening at its distal end. The light travels down to a table, desk or other support structure and is reflected back outside the opening in the cavity. The conical shape of the cavity is so defined that the light from the transmitter is focused, whereby the light is not reflected back into the central housing when the sleeve does not cover the central housing. As such, the receiver 422 does not detect the light sleeve is therefore not located over the end sensor 418. When the sleeve 414 is moved so that the sleeve 414 covers the opening at the end of the cone-shaped cavity, the light from the transmitter 420 is reflected back into the cone-shaped cavity and the receiver 42 is detected. the presence of the sleeve 414 covering the end sensor 418. The divider 424 is optional and can be used to prevent the occurrence of crosstalk, the receiver of which would detect light from the transmitter 420. The end sensor 418 is shown in this embodiment as an optical type sensor. The receiver 422 may alternatively be located outside the central housing 412 and use continuous beam detection to detect the proximity sleeve 414 has been flattened past the end sensor 418. While an optical end sensor is shown, it should be understood that other sensors or switches could also be used (eg proximity switch, half effect a capacitive switch or sensor). An advantage of using an optical end sensor is that the user does not feel the end of the travel path 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 around the central housing 412. Before the end sensor detects movement of the sleeve 414 past the end sensor 418, a given set of sleeve movements correlates with a given amount of pointer movement. As soon as the end sensor 418 detects the presence of the sleeve 414, a larger amount of pointer movement is given for the same given amount of sleeve movement. Referring to Figure 20c, a central portion 400b of the pointing device with internal sensor is shown. A sensor 430 is shown arranged on the circuit board 416 and held in place by a sensor housing 432. In a certain embodiment, the sensor is implemented as a laser sensor, although other embodiments may use different types of sensors. The sensor is used to detect any rotation and / or sliding movement of the sleeve 414 with respect to the central housing 412. A retaining spring 434 is used to bias the sensor 430 and the sensor housing 432 into place within the central housing 412. A portion of the sensor housing 432 extends into a opening within the central housing 412, so that the sensor 430 detects movement of the sleeve 414, and is locked in place by the function of the retaining spring 434.
Referring to Figure 20d, a cross-sectional view of a right portion of the pointing device 400c with internal sensor is shown. Similar to the left side described in connection with Figure 1b, a block 448 is located between the circuit board 416 and the central housing, which is kept in mechanical connection with the circuit board 416 through a second pin 458. Furthermore, the second end sensor 450 is shown as includes a transmitter 452, a receiver 454 and a divider 456. In use, the second end sensor 450 detects when the sleeve 414 has moved so that the sleeve 414 covers the end sensor 450. When the sleeve does not cover the end sensor 450, light travels from the transmitter 452 through the cone-shaped cavity and passes through the opening at its distal end. The light travels down to a table or desk and is reflected back outside the opening in the cavity. The conical shape is so defined that the light from the transmitter is focused so that the light is not reflected back inside the central housing, when the sleeve does not cover the central housing. As such, the receiver 454 does not detect the light, therefore the sleeve is not arranged over the end sensor 450. The proximity sleeve is moved so that the sleeve covers the opening at the end of the conical cavity, the light from the transmitter 452 is reflected back into the conical cavity and detected by the receiver 45. the presence of the sleeve covering the end sensor. The divider 456 is optional and is used to prevent the occurrence of crosstalk, otherwise the receiver 454 would detect the light from the transmitter 452. Each end sensor (418 in Figure 1b and 450 in Figure 1d) is shown as located at a predetermined distance along the central housing 412 from the ends of sleeve 414, when the sleeve 414 is at a dead center position on the central housing 412. This is done to allow a certain amount of pointer movement before an accelerated pointer movement is used. Alternatively, the end cap sensors 418 and 450 may be positioned near the ends of the sleeve 414, when the sleeve 414 is at the dead center, to facilitate centering of the sleeve 414 for detection and placement along the central housing 412.
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 pushed down, the sleeve 414 and the central housing 412 rotate the pivot point and activate the pick switch. ("Pick switch") 440. The amount of force required to activate the pick switch ("pick sWitch") can be adjusted by using the pick adjuster 442, which is connected to the first spring444. The first spring 444 is connected at one end to the pin attached to the block 488, while the second end is in mechanical connection with the second spring 446. The second spring 446 has a first end in communication with the first spring 444, while the second end is attached to a block. The pick adjuster 442 is movable in the horizontal direction, leading to a change in the amount of force required to release the pick switch 440. This is particularly useful when performing different actions with the pointing device based on internal sensor. When a user performs several pull-and-drop actions, it may be desirable to have the picking power set high so that elements are not inadvertently released while being pulled. On the other hand, when a user performs several click-type actions with no or little pulling action, it may be desirable for the picking force to be low, so that it is quite easy to pick objects.

In addition, the pointing device includes a circuit 16 in communication with the sensor, the circuit being capable of transmitting data to a computer for the rotational displacement and the horizontal displacement.
In a certain embodiment, a mode can be entered which is referred to here as "effect scrolling". When the sleeve is at or near the end of its travel path on one or the other side of the central casing, a power scrolling mode enters, where the sleeve can be used as a scrolling wheel to quickly scroll through a document. Moving the sleeve away from the end of the central housing causes the power scrolling mode to exit.
