Flexible frictional resistance with computer mouse and mouse pad.

Description.

The invention is in the field of the operation of the computer mouse (mouse) according to the physical law, whereby the human motor skills, which also follows this natural law, can move the mouse faster, more accurately and more relaxed than with the conventional mice. This is achieved by an extreme frictional contact between the computer mouse and its substrate, whereby the position of the physical origin of the cursor can be felt and recognized. Hereby disadvantageous irregularity of friction is leveled by the use of a newly developed mouse pad.

15

In conventional mice, the friction between the mouse feet and base, through greasy material or through the smallest possible contact area, is minimized to minimize the adverse irregularity of friction. However, this also reduces the frictional resistance. This is very disadvantageous, because a moving mass (mouse) always requires a counterforce, such as a resistance, to change course or to reduce the speed of movement. With the current, slightly sliding mouse, the necessary resistance (unbranded) is brought about by static muscle tension. This force contradicts the dynamic muscle strength and causes irritation with muscle complaints in the long run. A legally correctly constructed computer mouse can be moved faster, more accurately and more naturally.

Mouse foot.

The computer mouse rests on the surface (mouse pad) via newly developed mouse feet. The mouse foot has a support surface on its bottom that rests on the surface.

1039405 2

This support surface has a limited (limited) size between 11 mm 2 and 0.1 mm 2. Due to the small but determined support surface, a concentrated frictional resistance is created which must not be too light and not unnecessarily heavy for the horizontal muscle force. The final size between 11mm2 and 0.1mm2 that the support surface ultimately has in production depends on the mouse ultimately produced with its weight and structure.

Human motor skills can focus on the concentrated frictional resistance as a fixed factor, due to the fixed size of the support surface. This allows a fast, solid scan to take place and the right muscle strength to be mobilized.

15

In this invention, therefore, it is a small but determined support surface under the mouse foot, for a highly concentrated frictional contact and not a support surface that is as small as possible with the substrate for the lowest possible (annoying, irregular) friction, as with some other mice are described and intended. With a support surface of 0.1 mm2, a usable frictional resistance can still be achieved on a new type of mouse pad. This surface of 0.1 mm 2 is larger than the interface between a spherical mouse foot on a flat surface.

The new mouse foot will get stuck on a common hard surface such as a table top, irregular scratches and on a soft conventional mouse pad. Moreover, a solid friction surface is not guaranteed on a conventional soft mouse pad. A spherical mouse foot can easily vary here due to the varying movements of the hand and mouse. Due to this variation, our motor skills cannot accept and use this as a fixed, concrete factor.

3

With 11 to 0.1 mm 2, the friction between the mouse foot and the new suitable mouse mat is highly concentrated during the mouse movement. This makes it possible to sense (recognize) the position of this frictional contact through the fixed housing of the mouse. A frictional contact larger than 11 mm 2 is too woolly and scattered to be recognized in its position by the nerves of the sensitive fingertips. A frictional contact smaller than 0.1 mm2 is too low to be able to be observed stably, continuously.

10

The virtual Cursor that we observe mentally on the screen has its origin in the tracking (motion follower, diode with sensor). We cannot physically grasp this tracking for a virtually physical movement of the cursor, which the physical person would initially like to do. We can place the tracking in the neighborhood or at the same position of the described, tactile frictional contact between the new mouse foot and its base. In this way we obtain a physical contact with what we perceive mentally on the screen. This body-mind coordination allows motor skills to function better than with conventional mice.

Optimization.

By placing the mouse foot with its concentrated tactile frictional contact on the ground within a radius of 8 mm from the center of the projected tracking spot, the motor system can orient itself well at the position of the tracking. See fig. 11.

The orientation is enhanced if the mouse foot is arranged adjacent to the tracking spot or partially in the tracking spot. The mouse foot can have openings such as slots, holes and cavities, through which the tracking light can shine through to the sensor. See Fig. 1-4.

4

By manufacturing the mouse foot entirely or partly from transparent material such as glass, through which the tracking light can shine, the position of the tracking and the tangible frictional contact on the mouse pad is purely identical, for an optimal recognition of the cursor. origin. See FIG. 5.

The bottom of this transparent mouse foot is dull, matted or anti-reflective to prevent reflection of the LED or Laser beam on the border of the transparent material. After all, it makes no difference for the tracking whether the substrate as such is objectively read or whether its print is read against the transparent mouse foot.

By mirroring the tracking light, the tracking spot on the surface can be shifted horizontally relative to the position of the LED or Laser and sensor. An opaque mouse foot can be arranged adjacent or partially in the tracking spot. A transparent mouse foot can be fitted entirely in the tracking spot. The advantage of this is the optimum, short contact between the scanning finger tip and the frictional resistance with cursor origin. See FIG. 6.

Mouse pad.

Friction between two surfaces can be seen (at the microscopic level) as irregularly "hooking" into each other's surface roughness and irregularly "breaking loose" here with sufficient muscle strength.

The more strongly these surfaces are pressed against each other, in order to, for example, want to brake the conventional mouse, the more strongly the adverse irregularity of the friction manifests itself. The motor cannot legally deal with this and therefore cannot really control this mouse. However, the new mouse pad is suitable for the concentrated frictional contact with the new mouse foot. The adverse irregularity of friction is neutralized by a flexible relief on the top layer of the mouse mat, over which the mouse foot moves. The flexibility is achieved by rubbery, elastic material such as soft PVC.

The (non-textile) relief is expressed in terms of "mountains and valleys" or rather "craters and mountain ranges".

(Two craters at least next to each other result in a "pointed" mountain peak 10 and not a "convex" mountain peak.)

The horizontal distance between the deepest points with two immediately consecutive craters is defined between 0.01 mm and 1 mm.

The depth of a crater is defined between 0.01 mm and 0.3 mm. See FIG. 8.

As is known, flexibility has a certain resistance and delay in bending the material. A fast moving mouse foot will bend the (vertical) flexible, pointed 20 "mountain top" to a minimum and experience a slight frictional resistance on these tops.

If the mouse foot is moved slowly, there is more time for the mouse to bend the flexible mountain top. The side wall of the mountain top is then bent from vertical to horizontal and presses it against the mouse foot due to its elasticity. Because this former side wall has a larger surface area than the top of the mountain, there is greater frictional resistance.

This means: the faster the movement, the lighter the resistance and the slower the movement, the heavier the resistance. As a result, the muscles do not have to provide extra static tensions.

6

Mountain peaks where the frictional resistance protrudes above the average (getting stuck stronger in the roughness) can bend further downwards elastically in the remaining crater opening. The hooked grip then releases and the muscle strength can remain undisturbed at the same level and the mouse regularly move.

This is different from a (convex) mouse foot that is sunk into a soft mouse mat and forces the mass of the mat as a whole horizontally away during its movement. Above-average frictional resistances cannot bend away separately.

By carrying out the relief of the mouse mat in "soft" PVC, by adding plasticizers, the "hardness" temperature becomes sensitive. With a rapid movement of the mouse, it has a relatively short time to release its frictional heat to the relief, which keeps the mountain peaks relatively rigid and keeps the frictional resistance relatively low.

A slow movement of the mouse has relatively more time to release its frictional heat, making the material softer faster and making the mountain peaks bend more easily, causing a rapid increase in the friction surface and its resistance.

Optimization.

With only 3 mouse feet, the mouse remains parallel to the mouse pad 30 and with this minimum number the motor can best orient itself to the frictional positions of the mouse feet on the substrate. (With 3.6 mm 2 contact surface per foot, the mouse rests with 10.8 mm 2 on the substrate. See claim 2.) 7

The 3 mouse feet can be placed in the shape of an isosceles triangle under the mouse, with 1 foot at the mouse nose and 2 at the back of the mouse. We can mentally remember this geometric shape. By placing the tracking point in the middle of the height line of the triangle, it is possible to orientate at this position by feeling the 3 friction positions at the mouse feet. See FIG. 9.

The mouse mat with one thickness can be made for one half of hard material 10, on which 2 greasy mouse feet on the back of the mouse experience minimal friction. The motor can then unambiguously orient itself on the strong frictional resistance of the mouse foot on the mouse nose, which is supported on the other half of the mouse pad, with the described flexible relief. See FIG. 10.

15

The friction positions can be scanned through the fixed mouse housing through the nerves of the fingertips. This is enhanced if a fingertip rests directly above a mouse foot on the mouse bottom or on the sensor which is arranged above the mouse foot or on a rigid connecting rod which is arranged above the mouse foot or the sensor. See FIG. 12-17.

The mouse control is further refined by a small dot or switch button that is enclosed by the skin of the fingertip and can exert horizontal force on it. See FIG. 12-17.

Furthermore, the mouse has two horizontal platforms on which, among other things, the thumb and little finger can lie and on which the said mouse feet are arranged. For optimum orientation on the frictional contact between the mouse foot and base, the distance between the top of the plateau and the bottom of the mouse foot is defined between 0.3 mm and 2 mm, so that the finger is 2 mm above the friction point. the substrate is positioned.

Conclusion of the invention.

With conventional computer mice with their open space under the sensor, which are used as so-called laptop mouse "off-desk", the hairs and folds of the clothing fabric or chair seat disturb the accuracy in reading the substrate. Light-transmitting material such as glass the size of the bottom of the mouse, through which the tracking light can shine, will fold and crush its hair and smooth it out, so that this surface can be read more accurately. Here, the bottom of this glass mouse foot, as described, is matted to prevent inner light reflections. See FIG. 7.

Fig.6 Shows how the tracking spot is shifted horizontally by mirroring the tracking light twice. In this figure a transparent mouse foot is shown, while the principle can also be applied to an opaque mouse foot, wherein it is arranged adjacent or partly in the tracking spot.

Fig. 7 Shows the use of a large transparent bottom under a computer mouse that smoothes out unevenness and has a matted underside M to prevent internal light reflection.

FIG. 8 shows the relief with craters (valleys) and pointed mountain peaks. D indicates the defined distance, from 0.01 mm to 1 mm between two deepest points of two immediately following craters. F indicates the defined height from 0.01 mm to 0.3 mm. E is the height of at least 0.01 mm with which the relief is homogeneously connected to the bottom of the mouse pad.

At A the mouse foot is moved quickly over the mountain top and there is a slight friction. At B, the mouse foot is slowly moved so that the mountain top can bend flexibly, elastically and more frictional surface forms (mountain wall). At C the mouse foot moves very slowly over the relief with an even larger friction surface (mountain wall).

FIG. 10. In this drawing, the tracking point T is in the same position as a mouse foot st at the mouse nose. With MF, smooth mouse feet are represented on a hard, smooth surface B, while part A of this surface has the described flexible relief. Both parts are equally high and seamlessly connected. As a result, it is possible that the mouse (with 3 feet) is stable, parallel to 1 surface, while the concentrated friction only manifests itself at the mouse nose, on which the motor system can orient itself.
