the ergonomically shaped computer pointing device incorporating the present invention is shown at various angles and with or without showing the operator &# 39 ; s hand from fig1 to fig8 . electrical functions of the invention as a computer pointing device is the same as those of the modern - day computer mouse , which allows the user to move the cursor on the monitor or display ( not shown ), turn the scroll wheel , and click the various buttons as necessary actions for interacting with the computer ; and hence , it is not necessary to describe these electrical aspects . pointing device 101 is shown as a right - handed version and 113 is shown as a left - handed version . it is also very feasible to design a version that is ambidextrous . that is , a design that can be used by either hand . scroll wheel 102 , located near the neck of the pointing device on the left side , is to be operated by the thumb using the inner joint 108 as contact and rubbing area . the thumb moves in a sideway motion for rotating the scroll wheel . buttons 103 and 104 , located along the left side of the pointing device , are designed to be operated by the thumb &# 39 ; s inner joint 108 in a pressing action . button 104 is optional in a simplified design . the locations of scroll wheel 102 and buttons 103 and 104 may be swapped in different embodiments . buttons 105 and 106 are located on the front side of the pointing device , possibly slightly away from the center line for convenient right hand ( or respectively , left hand ) operation . buttons 105 and 106 are optional in a simplified design . electrical cord 112 connects the pointing device to the computing system , be it a personal computer or a gaming console or any other electronic device that can utilize a pointing device input . in a wireless embodiment , the cord 112 is not present and its function is substituted by a radio wave , optical , sonic , or any other feasible interface medium . the tip of the pointing device is designed to be tilting forward for its function , allowing easy grip and lifting by the gripping hand , and its form . it is also feasible to vary the shape of the tip , for example like a mushroom head without sacrificing the utility of the pointing device . the base 116 , seen from bottom view as shown in fig8 of the pointing device , is approximately an oval shape with its long axis in line with the direction of the forearm . more precisely speaking , the shape is a pear - like shape with the smaller end at the front side . 117 is an approximate location at the bottom 116 of the pointing device where a moving ball or an optical sensor can be placed for sensing the x - y movement . base edge 107 allows intimate contact to the little finger and the base of the palm , while allowing the little finger and the base of the palm to be contacting and sliding against the work surface at the same time . the hand , including the palm and the fingers , comfortably contacts the pointing device completely as shown in fig3 . contact area 110 is the contacting area between the pointing device and the u - shape formed by the thumb and the index finger . 108 is the center region of contact between the thumb and the pointing device . contact area 107 is for the little finger and the base of the palm . the whole inner palm , not shown in the figures , is also in general contact with the pointing device surface . this is a very natural upright and ergonomic position for the hand and the forearm . the main conic surface of the pointing device is forward tilting by approximately 20 to 45 degrees from an absolute upright position with respect to the base 116 . the profile is clearly shown by fig1 in a front view and fig2 in a side view . fig5 shows a top view . fig6 and fig7 show a left - handed embodiment , with mirrored placement of the buttons , such as 114 , and the scroll wheel 115 . it is entirely feasible to design an embodiment that is ambidextrous . for example , one can make the scroll wheel to be swappable , or have two scroll wheels with one on each side . it is also important that when the scroll wheel and the buttons are activated , the fingers are engaged in a hooking action with the joints bending inward . in summary , the ergonomic aspects of the pointing device include 1 ) allowing the hand to maintain a natural upright position throughout the operation , 2 ) allowing all five fingers to be naturally curved inward while the whole palm is holding the device , 3 ) allowing the little finger and the base of the palm to be half resting on the work surface and half pressed against the base of the device , 4 ) allowing activation of the buttons and the scroll wheel by the user pressing the first joints of the thumb and fingers instead of the finger tips , 5 ) activation of the buttons and the scroll wheel promotes an inward hooking of the fingers towards the palm , 6 ) fitting a wide range of hand or palm sizes . the x - y movement of the cursor in the computing device is effected by either a standard rolling ball 117 or an optical or gyroscopic sensor 117 a that is mounted in the bottom or interior of the pointing device . the hand effects the x - y movement while holding the pointing device in a natural and nearly upright position . this is an easy - to - adopt style of operation after an initial familiarization step . it is also possible to implement the pointing device as a wireless input device that allows the user to effect x - y movement in the free air and without the need to move against a surface . as noted above , it is also possible to use a gyroscope for translating left - right rotation to x - movement and front - back rotation to y - movement . extra buttons and scrolling - wheel can be attached to the pointing device for auxiliary usage . for example , the scrolling - wheel can be in front of the pointing device for scrolling with the index finger or middle finger . another embodiment is a qwert keyboard that consists of one or a pair of pointing device handles on which the keys are arranged such that fingers type on them while keeping the hand in a natural upright position . a further embodiment is a combination of such keyboard and a pointing device of the invention . while the invention has been described in relation to preferred embodiments of the invention , it will be appreciated that other embodiments , adaptations and modifications of the invention will be apparent to those skilled in the art .
