Extended use of a computer-pointing device, such as a computer mouse, may cause a computer user to suffer from cumulative trauma disorder (CTD) or repetitive stress injuries (RSI). Computer users may often be afflicted with pains in the hands and the wrists that may be caused by excessive wrist movements such as flexion and hyperextension of the wrist. Computer users may also suffer from soreness and fatigue in the shoulders and the neck due to excessive arm and shoulder motions associated with use of computer-pointing devices.
Long periods of repetitive motion associated with the use of the computer mouse coupled with incorrect hand posture while using the mouse may cause disorders in the hand, wrist, elbow, shoulder, and neck, such as carpal tunnel syndrome, among others. Repetitive stress injuries, such as carpal tunnel syndrome, may be disabling and are costly to employers and employees alike, including both medical expenses and lost work time.
Furthermore, there are many different types of pointer control devices that include, but are not limited to, a touch pad, track ball, buttons, wheel and a stick. Typically a single type may be included with a mouse. This may present problems if a user prefers another type of device.
Accordingly, there is a need for a computer input system, such as, but not limited to, a computer mouse, which may reduce stress and help to prevent injuries while not impeding the productivity of the computer user. Further, it is desirable to provide more than one type of interchangeable pointing device controller, as desired by the user. Yet further what is needed is a system that may allow micro movements of the fingers of a user without having to move the entire hand, wrist and/or arm.
Provided are exemplary embodiments, which may include a system that may couple to a computer that may include a selectably interchangeable pointing device controller, and further may include an ergonomic design that may include a front portion and a rear portion where the front portion is configured to move horizontally and vertically with respect to the rear portion.
The detailed description set forth below in connection with the appended drawings is intended as a description of exemplary embodiments and is not intended to represent the only forms in which the embodiments may be constructed and/or utilized. The description also sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments. However, it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of this disclosure.
An input system according to an exemplary embodiment is shown in
Middle portion 40 may be made of a flexible material such as foam, rubber, or other flexible material and/or configuration such that front portion 20 may move independently of rear portion 50. With this configuration, a user may be able to make micro movements with the front portion 20 with respect to rear portion 50, such that the entire wrist and arm may not need to move to move front portion 20, and consequently, a cursor and/or pointer controlled by this system 10.
Front portion 20 may include a front end 22 as well as a back end 24. Furthermore, front portion 20 may include a surface contacting portion 26 that may be configured to contact a mouse pad or other support surface utilized by the input system 10 to control a pointing device. Front portion 20 may further include an input device portion 30 which may be interchangeable as described below. Input device portion 30 may include buttons 32 as well as side buttons 34 and wheel 60 to control the movements of a cursor or other pointing device, as desired.
Rear portion 50 may include a front end 52 and a rear end 54. Rear end 54 may include a rest 56 configured to receive a user's hand, heel of the hand, or wrist to rest thereupon. Rest 56 is typically made from a flexible, soft rubber or gel-filled fabric; however, other comfortable materials and configurations may be utilized, as desired.
Front end 52 or rear portion 50 may be configured to generally correspond to the back end 24 of front portion 20, such that it may be easier to move front portion 20 with respect to rear portion 50, as desired. It will be appreciated that with this configuration that front portion 20 may move laterally as well as vertically and horizontally with respect to rear portion 50 due to flexible middle portion 40. This may allow a user to accomplish micro movements while not moving their entire wrist and/or arm to move front portion 20 with respect to rear portion 50, to control the pointing device and/or cursor controlled by this system.
System 12 may also include a rear portion 50 which may be configured to receive the wrist of a user comfortably to further reduce repetitive stress injuries. Furthermore, rear portion may include a front end 52 which may generally correspond to rear end 84 of front portion 80 to allow more freer movement of front portion 80 with respect to rear portion 50. Furthermore, this configuration may enhance the use of the system 12 as well as help coordinate movements of front portion 80 with respect to rear portion 50.
Front portion 80 may also include a lower surface 66, which, with keel 28, may be non-planar. With this non-planer lower surface configuration, it will be appreciated that horizontal as well as vertical movements may be made with front portion 80 micro movements, such that a user may move the pointing device without moving the entire wrist or arm. Furthermore, front portion 80 and rear portion 50 may have an arch-like configuration, which may allow the fingers of a user to dangle over front portion in a ergonomic manner, which may further reduce the likelihood of stress injuries from occurring.
Front portion 80 may include a front end 82 and a rear end 84. Rear end 84 may be configured to couple to flexible middle portion 40, and to somewhat correspond front end 52 of rear portion 50. Rear portion 50 may include a rear end 54 as well as rest 56, which may be configured to support the wrist of a user in a comfortable and ergonomic position. With this configuration of system 14 this again may allow a user to move front portion 80 with respect to rear portion 50 without rear portion 50 moving. Again the arch-like configuration as well as the flexible and micro movement-capable configuration of the system may reduce the likelihood of repetitive stress injuries occurring.
It will be appreciated that although this system is shown generally as a computer mouse, other input systems are contemplated and encompassed by this disclosure. Furthermore, although a wireless mouse is shown, a wired mouse may be utilized without straying from the concepts disclosed herein.
With this highly configurable, modular configuration, different types of pointing input device portions may be utilized with one system such that a user may be more likely to purchase the system. Furthermore with the overall ergonomic features of the various embodiments, repetitive stress injuries may be reduced. Furthermore, the various embodiments may allow for micro movements of the front portion with respect to the rest of the system. Furthermore, these vertical and horizontal micro movements may be similar to that of a stylus or writing pen, as desired.
Current devices may require that the user's wrist change in flexure in varying degrees to operate the device. This new configuration may allow a user to not flex their wrist when using this device. This anti-flexure configuration may further reduce RSIs and other injuries without impeding the productivity of the user. It may increase the productivity and comfort of the user when using this device.
Furthermore, the various embodiments may be more stylish than other mouse configurations such that a user will be more likely to purchase it. Furthermore, the interchangeability of input device portions may make it attractive to a user, such that a user who may not have bought the item because of the type of pointing device controller, may be more likely to buy this device as it may have interchangeable pointing device portions. This design may enhance the user's enjoyment of the use of a computer and may be purchased because of its design alone.
The embodiments disclosed herein may be 1-10 inches long by 0.5-4.0 inches tall by 1.0-6.0 inches wide. It will be appreciated, however, that other dimensions and configurations may be utilized, as desired. The embodiments disclosed herein may be a mouse for a computer, but other types of hand furniture may be created with this same or similar design to reduce repetitive and/or cumulative stress injuries, among others, and be made to be attractive to consumers.
The rear portion 50 may be designed with materials having characteristics including the ability to displace proportionally to the user's hand or wrist given the weight of the user's hand or wrist thereby providing for a custom user fit every time the device is used. It is also contemplated that the rear portion 50 may be designed with materials that will provide displacement memory during each use of the device for a period of 1-10 seconds, for example, after the user's hand and wrist are removed from the device. The rear portion may be designed with materials that are body heat responsive to an individual user's body temperature. The device may also include a set of user-definable macros that may permit the user to perform repetitive tasks, such as pointing the device and depressing the buttons or similar action, with ease and minimal effort.
While the embodiments disclosed herein may be presented for a right-handed person, it will be appreciated that a similar device may be configured for a left-handed person. In addition, the size of the device may be adjusted to accommodate a range of sizes in the human hand. It will be appreciated that the device may be made in a range of sizes that may vary from a generally smaller device for small children through a larger device for adults with exceptionally large hands, as desired.
In closing, it is to be understood that the exemplary embodiments described herein are illustrative of the principles of the present disclosure. Other modifications that may be employed are within the scope of the disclosure. Thus, by way of example, but not of limitation, alternative configurations may be utilized in accordance with the teachings herein. Accordingly, the drawings and description are illustrative and not meant to be a limitation thereof.
