In a mouse that operates with the palm facing down, in order to grasp the mouse with the thumb and ring finger, all the bones connected to the wrist of the thumb, ring finger and little finger are moved from the normal position, and the palm also moves with the thumb, ring finger and little finger. Since you have to bend it inward and maintain that state while operating the mouse, your hands get tired, and you move the mouse with the thumb and little finger balls on the operation surface, so the thumb duck It is the cause of being able to do it.

The index and middle fingers are touching the mouse, but they are always floating, which gives tension to the muscles of the fingers, and the fingers extending from the palm, which is bent inward, hold the wheel and buttons in a difficult state to move. Since I am operating it, I get tired on both fingers.

In this way, when using a mouse, the palm and fingers continue to hold the mouse, resulting in poor blood circulation and tiredness throughout the hand. Especially in the work of continuously using the mouse, it is a work that leads to fatigue. Until the mouse was created, there was no tool created by humans to hold a specific shape on the fingers or palm.

Therefore, the subject of the present invention is to make a mouse having a shape that does not hold a certain shape on the finger for grasping, to prevent the thumb ball and the little finger ball from rubbing on the operation surface when moving the mouse, and each finger is easy to use. It is to create an input device with wheels and buttons arranged at the positions.

As in the sport of baseball, human hands are easy to grasp round objects, so we chose a mouse with a shape that uses a sphere that is easy to grasp with the palm and five fingers.

It is a hemispherical mouse that can be operated by placing the hand on the mouse without grasping the mouse with the thumb and ring finger or little finger, and can be grasped with the palm and five fingers as if wrapping it without force.

The wheel and left and right buttons can now be operated with the tips of the index and middle fingers that descend from the palm on the mouse.

An inclined surface was provided on the upper part of the hemispherical mouse to make it easier to put the palm on it.

A wide round chamfer was provided at the intersection of the inclined surface and the spherical surface.

Attach the wheel and its left and right buttons to the inclined surface so that the palm tilts and the hypothenar side comes downward when the index finger and middle finger are aligned with the wheel and the buttons on the left and right of it and placed on the inclined surface. It was.

The trackball was attached to a position where the fingertips could be placed by simply moving the thumb without moving the palm.

Small hemispherical protrusions were attached to the spherical surface and the inclined surface.

If you place your palm and fingers in their respective positions on the mouse, you don't have to grab them with your thumb and ring finger, just put them on and you'll be in a state where you grab the mouse.

When you put your palm on the inclined surface, five fingers come to a position where you can easily grasp the mouse, and you can operate it while lightly wrapping the mouse with your palm and all fingers, so when you move the mouse, put pressure on your fingers You don't have to, so you don't get tired easily.

Since both the thumb and little finger are placed on the mouse, they can be moved smoothly without getting in the way when moving the mouse. If you lightly grasp the mouse with the tips of your thumb and little finger, you can move the mouse by floating your arm without moving the position of the other fingers, so the ball of the thumb and little finger do not touch the operation surface and you cannot use the mouse. It is also possible to reduce the floating of the arm, move the ball of the thumb and the ball of the little finger while slightly touching the operation surface, and lower the arm at the same time as the position is determined.

Since it is lowered from the palm on the inclined surface, the index finger and middle finger that are placed on the button without exerting force can press the button with just the fingertips, and if the fingertips are placed on the wheel and the fingers are moved up and down, the wheel Because you can turn, the movement of the index finger and middle finger becomes smooth, and the fingers do not get tired.

When using a mouse, the same part of the palm and fingers touches the small protrusions on the spherical surface many times, and the palm and fingers remember their usual positions, so you do not have to check with your eyes to check your usual palms and fingers. You will be able to grab the mouse at the position of. You can also move the mouse by spreading your hands with a part of your palm and a part of your fingers resting on the protrusion.

Since there is a wide round chamfer at the intersection of the inclined surface and the spherical surface, the part in contact with the palm and all fingers becomes a gentle curved surface with no corners, and there are no corners that touch the skin of the fingers and palms, so they are touching. There is nothing that sometimes gives a feeling of resistance, and you can work relaxedly.

If you get tired of holding the mouse or want to change the working condition of your arm, just hold the spherical surface with your thumb and little finger without changing the position of your index finger and middle finger, and raise your arm. The mouse can be moved even if the palm is lifted from the spherical surface and the inclined surface, which makes the palm and fingers feel different.

Although the size of the mouse can correspond to the size of the hand, it is possible to manufacture a mouse corresponding to the size of the hand and the shape of the hand even at the inclination angle of the inclined surface.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.

In the figure, the spherical surface 6 of the hemispherical mouse 1 provided with the circular inclined surface 2 on which the palm rests is provided with a fan-shaped opening into which the trapezoidal frame 18 of the wheel 3 and the right button 4 and the left button 5 are inserted. Ribs 14 having the width of the above are provided on the left and right and upper three opening edges, and the lower part extends to the place where the circular base 9 is placed.

Slits 11 for making the buttons easy to bend are provided on three sides of the right button and the left button, and the ribs 14 and the button fixing ribs 15 are joined by an adhesive at the joining lines 13 on the upper three sides of the slits 11.

The right button 4 and the left button 5 are made of a material that bends when pressed, and have a fan shape that surrounds the trapezoidal frame 18 of the wheel 3. The spherical surface 6 and the inclined surface 2 are deformed because they receive the weight of the palm. It is made of a difficult material.

A hole for inserting the trackball 8 is provided in the spherical surface 6, and a circular frame 10 is attached so that the trackball 8 does not come out of the hole.

In order to allow the circular end of the spherical surface 6 that receives the weight of the hand to ride on the circular table 9, the circular table 9 is provided with a rise 19 that contacts the inner surface of the circular end, and the spherical surface 6 and the circular table 9 are provided with an adhesive. Is integrated. Further, a V-shaped groove is formed in the portion of the circular base 9 in contact with the edge of the circular end to prevent the spherical surface 6 from coming off.

An optical sensor is attached to the circular base 9.

A cord 12 connected to a personal computer may be provided, or may be wireless.
