SUMMARY OF THE INVENTION
The present invention is an ergonomically designed gaming device for a user that includes a semi-flattened hemispherical ovoid upper shell pivotally mounted on a flat, ovoid base. The upper shell is contoured into a general hand imprint shape with finger and thumb grooves and fingertip provisions to accommodate the user's index finger, middle finger, ring finger, little finger and thumb. A plurality of adjustment screws is provided for tilting adjustments for the general hand imprint shape. A plurality of tactile buttons and dual rocker switches are provided in the fingertip provisions for the user to incorporate into a computer game.
The shell is tilted so that the thumb rests higher than the little finger, the thumb resting almost on its side in the thumb groove. The upper shell may be tilted by rocking the hand slightly about the axis of the wrist. Rocking the upper shell clockwise about the axis of the wrist operates one switch mounted on the base beneath the upper shell, while rocking the upper shell counterclockwise about the axis of the wrist operates another switch mounted on the base beneath the shell. Operation of the switches mounted in the finger grooves, the thumb grooves, and beneath the shell allows the user to duplicate functions normally performed by the computer keyboard while resting his or her hand on the ergonomically designed computer device by very slight pressures of the fingertips, the thumb, or the wrist.
Accordingly, it is a principal object of the invention to move keyboard functions in a computer game from the computer keyboard to an ergonomically designed computer device which requires only slight pressure applied by the fingertips, thumb, or wrist of a single hand, while simultaneously resting the hand.
It is another object of the invention to provide an ergonomically designed computer gaming device that can be operated by touch, without looking at the ergonomically designed computer gaming device.
It is a further object of the invention to provide an ergonomically designed computer gaming device that can accommodate a large range of hand and finger sizes.
Still another object of the invention is to provide an ergonomically designed computer gaming device that is comfortable on a user's hand and wrist.
It is an object of the invention to provide improved elements and arrangements thereof for the purposes described which are inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention is an ergonomically designed computer gaming device 10, as shown in FIGS. 1 and 2. The ergonomically designed computer gaming device 10 comprises a semi-flattened hemispherical upper shell 12 pivotally mounted on a flat, planar base 20. Both the upper shell 12 and the base 20 are substantially ovoid in shape when viewed in plan view, as seen in FIG. 2. As viewed from the rear or palm depression, the upper shell 12 is not symmetrical. Rather, the upper shell 12 is tilted, as seen most clearly in FIG. 1. The degree of tilt may be approximated by placing ones hand on a flat surface, cupping the hand, and rotating the wrist to raise the thumb about two inches above the flat surface.
The upper shell 12 is contoured into a general hand imprint shape 30 having a depression for receiving the palm, finger and thumb grooves, and fingertip recesses to accommodate the user's index finger, middle finger, ring finger, little finger and thumb. A plurality of tactile buttons and dual rocker switches, described further below, are provided in the fingertip recesses for the user to activate as part of a computer game in lieu of a computer keyboard. The upper shell 12 rotates slightly, preferably about 5° clockwise and about 5° counterclockwise, about an axis 14 which extends from about the center of the palm depression through the tip of the middle finger groove in order to operate two normally open momentary switches disposed between the upper shell 12 and the base 20. The pivot mechanism may be an elongated shaft 16 extending along the axis 14 with hinges 18 extending from the base 20 and the upper shell 12 mounted on the ends of the shaft 16, by two separate hinges mounted at opposite ends of the shaft 18, by a detent mechanism, or by any other conventional pivot mechanism known in the art. The upper shell 12 may be maintained in a central or neutral position by one or more bias springs (FIG. 4, 40) which prevent accidental triggering of the momentary switches disposed beneath the upper shell 12. A plurality of adjustment screws (FIG. 4, 40) on the thumb side allow for tilting the base 20 up for adjustments for the general hand imprint shape 30.
The ergonomically designed computer gaming device 10 can be used to control movement in computer games and can be adapted to console game machines as well. The primary use of the ergonomically designed computer gaming device 10 is for games of the First Person Shooter type, but can be useful for other games as well. It is intended for use by the user's left hand, which is the hand normally used for movement by right handed persons, but can be made in such a manner that it could be used by left handed users as well.
The ergonomically designed computer gaming device 10 has a fingertip provision for the index finger groove 60 of the general hand imprint shape 30 that includes a third and a fourth tactile button 62, 64. Both the third and fourth tactile buttons 62, 64 are hinged at one end and are approximately 1.00′′ to 0.75′′ in length to allow for different users' U hand sizes. The third tactile button 62 is hinged at the end being furthest from the palm of the user, while the fourth tactile button 64 is hinged at the end being closest to the palm of the user. Both the third tactile button 62 and the fourth tactile button 64 follow the general contour of the index finger groove 60. The ends of the third tactile button 62 and the fourth tactile button 64 that are not hinged should be fairly close together, since the index finger has a high degree of dexterity and the movement from the third tactile button 62 and the fourth tactile button 64 is a relatively natural movement.
The ergonomically designed computer gaming device 10 has a fingertip provision for the middle finger groove 70 of the general hand imprint shape 30 that includes a second dual rocker switch 72. The second dual rocker switch 72 is similar to the first dual rocker switch 51 except the operation of the second dual rocker switch 72 is perpendicular to the middle finger groove 70 of the general hand imprint shape 30. The second dual rocker switch 72 should be higher at each of the top and bottom ends 73,74 and taper down to a bevel at the axis of the second dual rocker switch 75. This design allows the middle finger of the user to rest in the center on the axis of the second dual rocker switch 75. The second dual rocker switch 72 should be approximately 1.00′′ long and be as wide as the middle finger groove 70. The second dual rocker switch 72 is designed so a slight push forward of a user's middle finger activates the top end of the second dual rocker switch 73 and a slight pull backwards activates the bottom end of the second dual rocker switch 74.
The ergonomically designed computer gaming device 10 has a fingertip provision for the ring finger groove 80 of the general hand imprint shape 30 that includes a fifth tactile button 82. The fifth tactile button 82 is similar to the third tactile button 62 and is hinged at the end furthest from the user's palm and is approximately 0.75′′ long. The ring finger has a low degree of dexterity and can really only accommodate a single tactile button. The fifth tactile button 82 follows the general contours of the ring finger groove 80 and should be about as wide as the ring finger groove 80.
The ergonomically designed computer gaming device 10 also has a fingertip provision for the small finger contour 90 of the general hand imprint 30, which is a third dual rocker switch 92. The third dual rocker switch 92 is approximately 1.00′′ long and 0.75′′ wide. There is a left side 93 and a right side 94 that are separated by the axis of the third dual rocker switch 95. The outer edges of the third dual rocker switch 92 should be slightly raised and taper down to a bevel at the axis of the third dual rocker switch 95. This also allows the user's little finger to rest naturally along the axis of the third dual rocker switch 95 when not in use.
Referring to FIGS. 2 and 3, the ergonomically designed computer gaming device 10 has fingertip provisions for the thumb groove 50 of the general hand imprint shape 30 which include a first dual rocker switch 51 with two sides 52, 53 and a first and second tactile button 54, 55 on each side of the thumb groove 50. Note that the thumb groove 50 for a user's thumb to lie in is slightly wider than what is proportional to the user's hand. This is to allow for an up and down movement of the user's thumb within the thumb groove 50 to activate the first dual rocker switch 51 and the first and second tactile buttons 54, 55 within the thumb groove 50.
The first tactile button 54 is molded into the bottom of the thumb groove 50, the bottom being that portion of the thumb groove 50 that if the user's thumb were to go limp, it would rest on the first tactile button 54. The second tactile button 55 is located opposite the first tactile button 54 on the top of the thumb groove 50. The first and second tactile buttons 54, 55 are of low actuation force because a user must raise his or her thumb off of the first dual rocker switch 51 to operate the first or second tactile buttons 54, 55. The first and second tactile buttons 54, 55 give the user a click or some felt feedback to let a user know when they have been activated and should be generally flush with the contours of the thumb groove 50. The first dual rocker switch 51 should be raised at its outer edges along the centerline pivot point 56 to allow for ease of actuation. The surface pads of the first dual action switch 51 is the area where a user's thumb touches the first dual rocker switch 51 to activate a side of it and should be approximately 1.00′′ to 1.25′′ long. This allows users U with different hand sizes to use the same ergonomically designed computer gaming device 10.
The first dual rocker switch 51 is beveled down its edges to the centerline pivot point 56. To activate either side of the first dual rocker switch 51, the user must apply a slight pressure upward to activate the first side of the first dual rocker switch 52 and a slight pressure downward to activate the second side of the first dual rocker switch 53. The design of the first dual rocker switch 51 allows a user to roll his or her thumb up or down to use the first dual rocker switch 51 or raise his or her thumb to activate the first tactile button 54 or the second tactile button 55.
All of the tactile buttons and dual rocker switches described above are preferably flush-mounted with the surface of the finger grooves. Operation of the dual rocker switches and tactile buttons substitute for operation of selected keys of a computer keyboard. Control cables to the computer have also been omitted from FIGS. 1-3 for clarity in the drawings.
As depicted in FIG. 4, the ergonomically designed computer gaming device 10 can be tied into a USB personal computer keyboard driver 100 or a modified USB personal computer keyboard driver 110. Additionally, a user can also tie the ergonomically designed computer gaming device 10 into a game console connector 120 as well. All of the dual rocker switches 51, 72, 92, tactile buttons 54, 55, 62, 64, 82 and the plurality of adjustment screws 40 have electrical switches that can be tied into a USB personal computer keyboard driver 100 or a modified USB personal computer keyboard driver 110. The USB personal computer keyboard driver 100 or modified USB personal computer keyboard driver 110 can then be connected to a game console connector 120 if the user U desires.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
