Description
The present invention relates to the mobile phone input technology, relate in particular to dummy keyboard and be applied to mobile phone, in order to accelerate Information editor's apparatus and method.
In recent years because the telecommunications industry open-development, and the demand of the fast development of communication science and technology, made communication means go to e-mail, phone in a large number by traditional mail, the demand of mobile phone particularly easy to carry (being designated hereinafter simply as mobile phone), flourish especially, for example closely just be almost over over several years accumulation in the cell-phone number recruitment in Taiwan one year over, just can imagine that people are to having communicated by letter the demand of convenience.
For this reason, come the boundary to strengthen its competitiveness of product, utilize mobile phone to send and receive e-mail to be one to attract popularly to buy and almost be necessary function.
Yet owing to be limited to the Portability of mobile phone, the keyboard on the mobile phone is still with 12 keys of the keyboard interface of continuing to use international telecommunication telegram Advisory Board (C ITT) standard, promptly 0-9 and "
*", "
#" and in addition several Control and/or function key make up, the mobile phone shown in Fig. 1 10 for example, two soft keys 20,30 about it has, 35,12 standard keys 50 of shift key are combined into actual key and LCD display 40.Except the button that is used for general pure telephony feature input digit, if need switch to the information editing time so that just unusual trouble when sending Email.The mode that for example importing key assignments " C " just needs to connect by the circulation of 4 times " 2 " key that is 2 → A → B → C occurs, and bothers especially during input special symbol, for example desire input key assignments "＞" then more need by about ten times "
*" (certainly above-mentioned press bond number different with the mode of each defined key of tame manufacturer).This has just hindered people and has utilized mobile phone to use some comparatively wishes of sophisticated functions, as computer function and Email or the like.
Therefore, some higher mobile phone is to cast out the keyboard of CCITT fully and design a kind of dummy keyboard that shows on mobile phone in conjunction with the mode of personal digital assistant system (PDA) or title personal electric memo pad at present, and the mode of touching with finger is imported desired word again.Though had certain convenience, owing to will on little LCDs, show virtual key strong in number, touch with finger again or style of writing the mode of very little virtual key is to import desired word at interval, the chance of false touch is just very high.Secondly, owing to be that manufacturer makes by oneself, and be not to use the mode of CCITT keyboard, also inconvenient for the user who roughly is familiar with this standard key.Moreover above-described input mode all is unfavorable for the setting of input in Chinese.Therefore, in view of this, how improving the problems referred to above so that the input of Information is humanized, is to impel to propose motivation of the present invention.
One object of the present invention is to improving the inconvenience of present mobile phone input.
Another object of the present invention is to introducing the symbol that dummy keyboard can be imported with expansion in conjunction with the idea of ccitt standard key.
