Abstract:
1. A mouse for a computer system, said mouse capable of entering commands into a computer based on the location of a cursor which can be placed on a computer screen, when moving said mouse across a working surface, and being actuatable by a user to generate a signal to said computer, said mouse comprising: a casing having a bottom part resting on the working surface and an upper part, said casing longitudinally extending from a front end to a rear end and having transversely spaced sides, which are spaced so that said casing is positioned between distal phalanxes of a user's ring and little fingers, and a distal phalanx of a user's thumb, when a user's lower palm, user's ring and little fingertips, and a side of the distal phalanx of the user's thumb are resting on the working surface without gripping said mouse at a naturally relaxed curled fingers and hand position; a primary button disposed at an upper front portion of said casing so as to be actuated by a user's index finger, said primary button having an upper surface, which is angled to the front end of said casing; and a primary fingertip receptacle at least partially extending upwardly from said angled upper surface of said primary button and forming a mould around a user's index fingertip, when placed on said angled upper surface of said primary button slightly bent, said mould being tapered upwardly from said angled upper surface of said button at a height, which provides a moulded contact surface with said user's index fingertip, which allows the user to move securely said mouse in a forward or backward direction without actuating said primary button by said index fingertip, when moving said index fingertip forward or backward against said moulded contact surface by stretching or bending said index finger in order to effect vertical movement of a pointer on a computer screen in up- or downward direction, respectively, said primary fingertip receptacle enabling a user to effect horizontal movement of a pointer on a computer screen without the use of hand or arm movement of the user, when turning said casing around its axis in said receptacle, when pushing by a thumb or a little finger of the user against a respective contact area on a respective side of said casing, when operating said mouse, said primary button being actuated without actuating mouse movement by a force applied tangential to said angled upper surface of said primary button by said index fingertip, when stroking by said index fingertip said angled upper surface of said primary button in a combined down-forward motion against said moulded contact surface; a secondary button disposed transversely of said primary button at an upper front portion of said casing so as to be actuated by a user's middle finger, said secondary button having an upper surface, which is angled to the front end of said casing; a secondary fingertip receptacle at least partially extending upwardly from said angled upper surface of said secondary button and forming a mould around a user's middle fingertip, when placed on said angled upper surface of said secondary button slightly bent, said mould being tapered upwardly from said angled upper surface of said button at a height, which provides a moulded contact surface with said user's middle fingertip, which allows the user to move securely said mouse in a forward or backward direction without actuating said secondary button by said middle fingertip, when moving said middle fingertip forward or backward against said moulded contact surface by stretching or bending said middle finger in order to effect vertical movement of a pointer on a computer screen in up- or downward direction, respectively, said secondary fingertip receptacle enabling a user to effect horizontal movement of a pointer on a computer screen without the use of hand or arm movement of the user, when turning said casing around its axis in said receptacle, when pushing by a thumb or a little finger of the user against a respective contact area on a respective side of said casing, when operating said mouse, said secondary button being actuated without actuating mouse movement by a force applied tangential to said angled upper surface of said secondary button by said middle fingertip, when stroking by said middle fingertip said angled upper surface of said secondary button in a combined down-forward motion against said moulded contact surface; and a form of a rear part of said casing providing sufficient clearance between an upper surface and a rear surface of said casing, and a user's palm plane, and said user's index and middle fingers being placed in said respective receptacle slightly bent, and a lower palm resting on said working surface, so that said upper surface and said rear surface of said casing do not interfere with said user's palm plane, said lower palm resting on said working surface, and said user's index and middle fingers, when the user manipulates said mouse, said form of said rear part of said casing enabling a user to shift said mouse from a neutral position of said user's index and middle fingers, when placed in said respective receptacle slightly bent, by bending said user's index and middle fingers further into a pocket formed by the user's hand, when a user's lower palm, user's ring and little fingertips, and a side of the distal phalanx of the user's thumb are resting on the working surface without gripping or pinching said mouse at a naturally relaxed curled fingers and hand position, so that said mouse does not interfere with said user's palm lane and said user's lower palm resting on said working surface; wherein a moulded contact surface is at least partially defined by a second additional button having a middle finger contact area and disposed rearwardly from said secondary receptacle so as to be capable of being actuated by bending the user's middle finger positioned in said secondary receptacle and simultaneously pinching the mouse between a user's thumb and a user's ring and/or little fingertips; and wherein said additional buttons each are supported by planes arranged on respective sides of said casing parallel to said common plane of said casing, said additional buttons each are capable of sliding on a respective plane and thereby allowing the user to actuate said additional buttons each by bending said user's index or middle finger positioned in respective receptacle and simultaneously pinching said mouse between said user's thumb and said user's ring and/or little fingertips.
