DEVICE FOR OPERATING A MOUSE-OPERATED COMPUTER PROGRAM

Abstract: A device for operating a mouse-operated computer program. The device comprises a base (1) having an upwardly projecting handle (2) firmly secured thereto, which may also be linked to the base (1) for fixing in any desired position relative to the base. Furthermore, the handle includes an operating means (3) on top of the handle and/or on one of the sides of the handle (2), and/or on the actual base (1). A rolling means is provided on the underside of the base (1) in order to provide signals which can control the position of the mouse pointer on a computer screen. Furthermore, rolling balls or similar sliding means are provided on the underside of the base (1).

Description: DEVICE FOR OPERATING A MOUSE-OPERATED COMPUTER PROGRAM The present invention relates to a device for operating a mouse-operated computer program as disclosed in the preamble of claim 1. When operating a mouse-operated computer program it has hitherto been usual to use a flat object having push buttons for operation and a roller on the underside which controls the mouse pointer. These mouse-like articles have been given an ergometric shape so that they fit well in the hand, but during use the hand must of course be twisted from the natural position of rest, which causes constant tension in the elbow area. The use of such mice has been found to cause inflammation and pain in the arm when used over a long period of time. In order to avoid these static positions it has been recommended that the mouse should be used in different positions, and different types of underlying surfaces have been made which are supposed to give a better working posture, but none of these have proven to be satisfactory. In order to overcome some of these drawbacks a so-called mouse pen has been developed, but this has not been found to give the desired result either with regard to a normal working posture which does not cause tension in the arm. The objective of the present invention is to obviate the aforementioned problems of chronic pains and the inconveniences these entail. This is done by means of a device for operating mouse-operated computer programs, the characteristic features of which are disclosed in claim 1. Additional features ofthe invention are disclosed in the remaining dependent claims. By means ofthe device according to the claims there is provided a possibility of being able to work with mouse-operated computer programs without any anxiety about muscular tension and other pain since the hand will be in a normal position of rest without any twists ofthe arm, and the weight ofthe arm can rest fully on the device. Since buttons are located at different points the user will be able to change fingers when operating icons or similar in the computer program. In this way, static use ofthe fingers is also avoided, and thus any muscular tension which might result in chronic conditions will, in a simple manner, be avoided. The provision on the underside of the mouse of contact points in the form of rolling balls or sliding surfaces enables the device to be operated with ease of movement on the mouse pad in such a way that no extra strength will be necessary in order to move the mouse pointer on the screen. This means that the weight ofthe arm can rest on the device and that the usual small lift ofthe arm with subsequent muscular tension will disappear. The invention will be described in more detail below with reference to the drawings, wherein: Fig. 1 is a perspective view ofthe device for operating a mouse-operated computer program. Fig. 2 is a view ofthe device in Fig. 1 from the underside. Figs. 3a,b are schematic illustrations ofthe angles ofthe projecting part relative to the base seen from the side and from behind, respectively. Fig. 1 illustrates the device for operating mouse-operated computer programs, said device consisting of a base 1 with an upwardly projecting handle 2 secured thereto. On the top ofthe handle 2 there is provided a mouse-operating means in the form of, e.g., a toggle key 3, or also in the form of separate push buttons which can be operated by the user's thumb. However, the operating means 3 may be of any previously known embodiment of switches capable of actuating the mouse pointer in a computer program. Several operating means can also be provided on the handle and/or on the actual base which can be reached by the user's various fingers in order thus to obtain relief. On the perspective drawing the base 1 and the handle 2 are made in one piece. However, it will also be possible to make the handle so that it is linked to the base by means of link devices that are known per se, and can in a simple manner be secured in the desired position relative to the base. This is so because the device illustrated in Fig. 1 is intended for the average user, but there are also people who have certain twists relative to the normal plane as a result of previous fractures ofthe arm or other causes, and in this case the user will then be able to adjust the handle relative to the base to his particular normal position of the arm. In the same way, it will also be possible for left-handed people to adjust the device for left-handed use as the handle 2 has a small tilt towards the left ofthe figure relative to the base plane, which will not be particularly convenient for a left-handed person What is essential is that the handle 2 is fixed relative to the base 1 during use, and that when the user grips around the handle 2, the wrist and the arm will be in the position in which there can occur no unnatural twists ofthe arm which may cause tension In Fig 2 the base 1 is shown seen from the underside In the illustrated basic example the base is triangular in shape, but it will of course be possible to have a base of any other shape, the essential being that there is an operating ball 4 or similar which, during movement ofthe base 1 against the underlying surface, emits control signals to the mouse pointer on the screen In the illustrated embodiment in Fig 2, three balls 5 are provided which roll on the underlying surface during movement, the operating means 4 for the mouse pointer having a distance from any mouse pad relative to the balls so that it is in contact with the signal emitting means in the base The balls 5 cause the device to roll without any significant resistance on the underlying surface, which in turn is instrumental in ensuring that the user does not strain himself too much Sliding means that are known per se in the form of plastic elevations, or other suitable means which cause little friction, can of course also be used instead of balls 5 In the illustrated example, three contact points are provided, but it is of course also possible to provide more or fewer, although the three point device has been found to be particularly suitable It will also be possible to make the whole base 1 in the form of a sliding surface It has been proven that the most favourable tilt seen from the side is at an angle α of between 5 and 45 degrees, prefered 23 degrees, relative to a vertical line through the base, cf Fig 3 a, and seen from behind, cf Fig 3b, an angle β of between 5 and 45 degrees, prefered 10 degrees, relative to a vertical line through the base The figures relate to a right-handed mouse, in a left-handed mouse the same angles will apply, but then in the opposite direction with reference to Fig 3b Fig 3 a illustrates, seen form the side, also an angle φ of between 0 and 60 degrees at the top ofthe handle 2 relative to the horisontale plane The angle φ is prefered to be 20 degrees
