Description

The symmetric computer keyboard

The utility model relates to computer keyboard and typewriter keyboard

Existing computer keyboard is divided into four parts on layout, it is standard character key part (as figure one), the function key part, (F1～F12), numerical key part, cursor control key part, adopt international standards fingering when input with above-mentioned keyboard, fingering is the division of labor like this: promptly left index finger make a call to 5, T, G, B and 4, R, F, V key; Middle finger makes a call to 3, E, D, C key; Nameless make a call to 2, W, S, X key; Little finger of toe makes a call to 1, Q, A, Z key.But when thousands of students being carried out the fingering teaching, I find usually to misuse when the student operates left index finger and beat C key, 6 keys for many years; Wrong X, R, 5 keys beaten of middle finger; Nameless wrong beat E, Z and 4 keys, wrong W, 3,2 keys beaten of little finger of toe.Such mistake nearly all took place on one's body each student, and the student is interpreted as above-mentioned faulty operation: " though beating easily wrong like this ".

When people's both hands were imported by the standard fingering, the both hands forearm was splayed configuration, and the direction that left-hand finger is bent and stretched naturally is the left-falling stroke (Pie) of the Eight characters; The direction that right finger is bent and stretched naturally is the right-falling stroke (ㄟ) of the Eight characters.

The keystroke direction of student's left hand maloperation is the direction that left-hand finger is bent and stretched naturally just, also bends and stretches the direction of direction symmetry just naturally with the right hand.

The reason that above-mentioned mistake appears in left hand is because the direction of left hand keystroke and direction that left hand bends and stretches on physiology naturally are inconsistent, disagrees with the physiological symmetry of left hand and right hand.

The people has formed physiological symmetry in the evolution of long period of time process, be embodied on the quadruped locomotion particularly outstanding.The swaying direction of left and right arm; The direction of left hand and right hand boxing: left hand and right hand is had an effect easily by casting aside and press down direction respectively.Just think and allow left hand to go out fist be (and our left hand standard fingering just is this direction) that is difficult to be subjected to along pressing down direction.Physiological symmetry is also complied with in man memory for a long time, gets used to the symmetry memory.Yet the international standard fingering has but been run counter to upper limbs in physiological symmetry rule.For example: during right hand keystrokes, when right middle finger makes a call to 8, when I, K, comma key, just in time to bend and stretch direction naturally consistent with the right hand for the direction that finger moves, thereby handy.And during the left hand keystroke, as left middle finger impact 3, when E, D, C key, the trend of left middle finger is to press down direction, and left hand respectively to point the direction that nature shrinks be to cast aside direction.Thereby each finger of left hand will turn under the cooperation of wrist during by standard fingering keystroke and cast aside the right-falling stroke direction keystroke that direction becomes 40 ° approximately, therefore caused the fatigue and the maloperation of left hand.

The purpose of this utility model is: a kind of computer keyboard of symmetry input is provided, makes it to adapt to the physiology of human body and the symmetry of memory.Realize and improve the touch system of Ctrl, Alt, Shift, Esc, Del, Enter, Ins, backspace key simultaneously, significantly improve the function of standard character keyboard region.

The purpose of this utility model is achieved in that Q key in the letter key is moved to A key lower left; Key move to former Q key position; The B key moves to G key upper right side, can form the space between G, H key and V, N key like this, the DEL key can be placed between G, the H key, place two keys between V, the N key, put backspace key by the V key, put enter key by the N key, place the Ins key in former left shift key position, then space bar is shortened to three letters case length in situ; Place Ctrl, Alt key respectively near the space bar left and right side.Respectively place a shift key in Ctrl, the Alt key outside, other respective change is: the Esc key is moved on to former backspace key position, Substract key, equals' key are added to the pause mark key after, numerical key two the key positions that all move right.Next, the center-aligned of the centre joint between A key and S key and W key, other letter key is corresponding align also.

The utility model compares with keyboard in the past, and following advantage is arranged:

1, improves by layout again, realized the symmetry of right-hand man's fingering keyboard.The efficient and the accuracy of input have been improved.

2, realize the touch system of Esc, Ins, Ctrl, Alt, Del, realized the touch system of warm start simultaneously.

3, thoroughly changed the situation of enter key, backspace key touch system inconvenience, made the touch system of the very high key of these two utilization factors become simple and easy to do.

4, original shift key will switch with pinkie, and is very inconvenient.After the improvement, switch, the not high big thumb finger of utilization factor is applied, made full use of the dirigibility of big thumb finger again, make the switching of Shift become very convenient with big thumb finger.The capitalization conversion of so also using shift key to carry out single letter is more prone to.

5, the utility model intension of having enriched the standard character keyboard region has increased Ins, Del, Esc key and has reserved the space for the expansion of new key.

Fig. 2 is a planimetric map of the present utility model

Introduce embodiment of the present utility model below in conjunction with accompanying drawing.

Letter key Q is moved to A key lower left; Key move to former Q key position; The B key moves to G key upper right side, can form the space between G, H key and V, N key like this, del key can be placed between G, the H key; Place two keys between V, the N key, put backspace key, put enter key, place the Ins key in the position of former left shift key by the N key by the V key.Then space bar is shortened to three alphabetical bond distances in situ, place Ctrl and Alt key respectively near the space bar left and right side.Respectively place a shift key in Ctrl and the Alt key outside, other respective change is: the Esc key is moved on to former backspace key position, Substract key, equals' key are added to the pause mark key after, numerical key two the key positions that all move right.Next, the center-aligned of the centre joint between A key and S key and W key, numerical key and three row's letter keys have all been realized above-mentioned alignment like this, the major key panel that (numerical key arranges with first row's letter key, second and the 3rd row's letter key is exactly what align in the past) arranges like this can be irregular on the right side, by Esc and suitable expansion of quotation marks key just can be addressed this problem.

As follows according to the corresponding division of labor of above keyboard layout fingering:

1, left hand: forefinger is beaten C, F, T, 4 and V, G, B and backspace key; Middle finger is beaten X, D, R, 3 keys; Nameless Z, S, E, 2 keys beaten; Little finger of toe beat Q, A, W, 1 and, Tab, Capslock, Ins, add, subtract, the pause mark key.

2, the right hand: forefinger is beaten N, H, Y, 5, "enter" key" and M, J, U, 6 keys.The middle finger number of playing, K, I, 7 keys; Nameless fullstop, L, O, 8 keys beaten; Little finger of toe beats/, each key on branch, P, 9 keys and Master Keyboard right side.

Del key can be used alternatingly with left index finger and right hand forefinger.

3, thumb: space bar is used alternatingly by left and right thumb.

1) left thumb: the Ctrl and the shift key in the lattice left side that fans the air.

2) right thumb: the Alt and the shift key on the lattice right side that fans the air.

For example: beat Alt+F5 and can pin Alt key with right thumb, left hand is pressed the F5 key.The available left thumb of obelizing is pinned left side Shift, and the right hand is pressed/key.

Ctrl and Alt key can singlehandedly switch and also can with the hands switch: switch for singlehanded as Ctrl+F5; Ctrl+J is that both hands switch.

Because space bar has been condensed to three alphabetical bond distances, therefore, the Ctrl of both sides, space, Alt, shift key are in left and right big nurse finger range of control.Play the touch system that Ctrl, Alt, shift key have not only been realized above-mentioned key with big nurse finger, simultaneously big flexibly nurse finger also is easily when impacting above-mentioned key.

The utility model can also be taked following four kinds of modes:
