The backside keyboardAffiliated technical field
The invention belongs to a kind of keyboard layout mode and the mode of operation of portable terminal electronic equipment (such as panel computer, MP4, mobile phone etc.).
Background technology
The mobile electronic devices such as present computer, mobile phone, MP4 mainly contain two kinds aspect input mode: 1. keyboard, mouse/touch plate type, take desktop computer, notebook computer, with the mobile phone of keyboard, MP4 as representative; 2. touch-screen type is take panel computer, touch-screen mobile phone, navigating instrument as representative.These two kinds of input modes can be competent at the traditional user demand of people.But people more and more pursue office in movement, internet exchange, amusement etc. instantly, and present Radio Transmission Technology (such as 3G) so that the mobile network generally accept for everybody.And traditional keyboard adds the mouse mode and is difficult in the situation that there is not worktable to use, and is have more than is needed when standing or couching, and can not operate under the state that a little vibrations are arranged waiting by bus; Touch-sensitive display, no matter then hand-written or soft keyboard input, input speed is all slow many than keyboard typing, and touch-screen easily produces maloperation, moreover because holding on the other hand equipment, touches on the other hand and writes, also the inadaptable environment that a little shake is arranged.
Summary of the invention
For solve terminal electronic equipment character input speed in mobile the use slow, the support platform had rely on and the problem of restriction people's use attitude, the present invention has designed a kind of keyboard layout mode and mode of operation, this mode is arranged on the equipment back side with Master Keyboard, ten fingers have been taken full advantage of on the one hand, and depend on present most people and can use rapidly and accurately touch system, so that the typewriting input keeps fair speed; On the other hand, come putting equipment without any need for table top, be not subjected to the attitude restrictions such as the people stands, sits, lies, and so long as not big bang too, all on the typewriting input without large impact.
The technical solution adopted for the present invention to solve the technical problems is: a cover keyboard is set at the back side of terminal device (take panel computer as example), two hands are tactile to be pressed in order to adapt to, it is divided into left button panel and right button panel, also has touch pad, on the left and right side frame of front screen, some major keies are set in addition.During use, the people stresses on both hands the left and right side frame of panel computer, with left and right sides palm firmly hold body relative to brave fork position in the face of screen.Right-hand man's thumb touches presses positive key, and all the other 8 fingers touch the left-right key panel of press the panel computer back side with the form of touch system, realizes and the notebook computer effect of similarly typewriting.Wherein, the key name of front and back and the arrangement of key make appropriate arrangements according to actual needs and change; Bottom surface keyboard region and positive frame button arrange keypad lock, prevent false triggering when not needing button; Can add in addition and join rotatable support in order to lie against desktop.In all cases, as long as both hands can use simultaneously, namely no longer be subjected to other condition restriction, all can guarantee fast and easily typewriting input.
The invention has the beneficial effects as follows: satisfied people when using the mobile device such as panel computer, to the demand of the aspects such as efficient typewriting input, unconstrained unrestricted, stable operation.No matter handle official business, internet exchange or Entertainment, no matter stand, sit, lie, whether no matter desk or platform are arranged, also no matter in by a small margin vibrations, the operation such as all can typewrite easily.

Embodiment
Present design can be used on the equipment such as panel computer, mobile phone, MP4, is illustrated as an example of panel computer example here.
Fig. 1 illustrates the user at work, stresses on both hands left and right side frame, holds body with left and right sides palm and brave fork position.Under the state of no matter stand, sit, lying, all can realize holding and operating body.
In Fig. 1 and Fig. 2, can see, be provided with a cover keyboard in the operational zone (back side) (2) of panel computer, i.e. left button panel (3) and right button panel (4), and be furnished with touch pad (5); Four fingers of right-hand man except thumb touch respectively the right and left key panel by the back side.In addition, the arbitrary finger except thumb all can be controlled touch pad (5).
In Fig. 3, the frame position of screen (front) (1) also is provided with left frame key zone (6) and left frame key zone (7).This moment, the thumb of two hands can touch by the key mapping to the screen frame.
The keyboard region at the back side and positive frame key-position area have comprised all major keies on the conventional keyboard, and according to ergonomics appropriate design are carried out in the key body position, like this, can utilize whole ten fingers, knock out all characters quickly and easily.
