Description
Technical field
The utility model relates to electronic technology field, particularly is used for a kind of induction type touch keyboard with haptic feedback functions of portable terminal; Be a kind of user interface device and portable terminal thereof concretely.
Background technology
Along with development of Communication Technique, mobile phone is a kind of as portable terminal, has become dark popular means of communication.Mobile phone along with user's needs just towards miniaturization, hommization, variation and datumization develop.Traditional mobile phone is mainly based on conversation.This requirement to user interface device is simple relatively.Mobile phone key keyboard based on the electric mechanical switch principle has been well positioned to meet requirement.This keyboard generally includes ten numeral/alphabet keys of 0-9, and the several function key.The button below is provided with spring caps, and after button was pressed, the contact of the conductive layer of spring caps was also connected electric switch.The button push action is accepted the back spring caps from the meeting original position of moving, and forms tactile feedback, and prompting user actuation of keys is finished.The electric mechanical switch technology that keyboard uses has been sound, and is easy to realize dependable performance.Yet along with increasing cellphone subscriber brings into use picture Email (Email), multimedia message (MMS), instant messages (IM) and short message mobile phone Word information communication modes such as (SMS), the literal input has proposed new requirement to user interface device.And the literal of non-letter that input characters is especially imported as Chinese on the conventional mobile phone key board is the very thing of difficulty of part.Develop rapidly along with communication service, particularly be accompanied by broadband The Application of Technology such as GPRS, this type of business can require the user to import more information, and existing user interface device can not satisfy above requirement again, and this is restricted with regard to the widespread use that makes information service.
Various novel user interface devices are applied on the mobile phone.The touch-screen that for example has hand-write recognition function also is used in input characters on the mobile phone.Two kinds of popular touch-screens are respectively resistive touch screen and capacitive touch screen at present, and resistive touch screen is to be made of deformable resistance film of one deck and the fixing resistance film of one deck, and is middle isolated by air.Its principle of work is: when with pen or during the user's finger contacts touch-screen, the upper resistors compressive deformation also contact with lower resistors, the position that the lower resistors film just can induce or the user points.Second kind is the capacitive touch screen technology, and the principle of work of capacitive touch screen is the same substantially with resistive touch screen, it mainly be by writing pencil when substrate is exerted pressure, the position of writing pencil is located in the change of capacitance.This novel user interface device of touch-screen has well solved the problem of literal input.Yet, in order to keep the small and exquisite of mobile phone profile, have only a touch-screen in these class mobile phones designs of great majority and omitted keypad.Also can be used for showing a dummy keyboard on the touch-screen, such design, the user just needs to click the virtual key that shows on touch-screen and dials.Dummy keyboard does not provide tactile feedback, and the user can feel to use inconvenience usually, and is easy to generate faulty operation.Also have the existing touch-screen of some mobile phones that numeric keypad is arranged again, the unavoidable volume of such mobile phone is big, carries inconvenience.In a word, touch-screen is difficult to well satisfy simultaneously number dialing telephone call, literal input, and the requirement of miniaturization.
Also be used on the mobile phone as the touch pad that is used on the notebook computer recently, for example, the disclosed device of US2003048257, on Nokia (Nokia) 6108 cellular phone flip keypad is housed, the user dials on button, opening renovating of keypad, is exactly a touch pad below.The user can use input pen input characters on touch pad.When the user write the stroke of literal with input pen on touch pad, the pressure that the special IC controller in the mobile phone produced when sensing input pen and streaking on touch pad changed.And then the position of stroke on the XY coordinate just go on record, and deliver on the handwriting recognition processor.The several candidates' that are consistent with the input stroke character will be output and be presented on the display then.Next, the user clicks menu and icon with input pen and searches and select to confirm or delete the shown character that goes out on touch pad.But have touch pad and digital keys simultaneously, increased mobile phone cost and mobile phone overall volume.
US2003025679, EP1197835 disclose similar user interface device, and the design that has touch pad and key board is simultaneously improved.Touch pad directly is contained in below the key board.The button below is provided with spring caps.For the electric mechanical switch of key board is able to work,, on touch pad, all to make a call to a hole accordingly at each button.Like this during pressing keys, thereby the machinery of button is leant on and just can be passed touch pad smoothly and press spring caps.The conductive layer contact of spring caps is also connected electric switch.The button push action is accepted the back spring caps from the meeting original position of moving, and forms tactile feedback, and prompting user actuation of keys is finished.The function of key board is kept, and number dialing telephone call is very convenient.When the user points when surface of keyboard slides, contactless touch pad and coupled special IC controller thereof are by the principle of capacitive sensing, measure and export the motion track of user's finger, and then realize that hand-write recognition function comes input characters on mobile phone, or moving cursor control user interface.Here the electric mechanical switch of button is controlled by the different independent circuits of two covers respectively with contactless touch pad.Wherein scanning parallel circuit separately all works alone simultaneously, and then monitoring and judge that whether the user points pressing keys, or whether user's finger has increased power consumption in the surface of keyboard slip.
US5917906 discloses user interface device, and the design that has touch pad and keyboard is simultaneously improved.On touch pad, add one group of spring caps and separation layer.Separation layer comprises that one group of aperture and spring caps are complementary, like this upper surface opposed flattened of spring caps and insulation layer structure.Their the top very smooth input face that indicates the button sign that adds again.When with pen or user's finger presses button sign, spring caps provides tactile feedback, and the contact portion of spring caps and touch pad produces pressure simultaneously, thereby realizes the function of button by the location determination of touch pad pressed part.When band power is slided on input face with pen or user finger, judge by the track of touch pad pressed part and to realize hand-write input function.This scheme provides hand-write input function and has had the function of the button of tactile feedback.Yet there is following defective in it.The first, when with pen or user's finger presses button sign, spring caps has certain area, and is also inhomogeneous with contacting of touch pad.Stressed by contacting, how to judge whether button is pressed to be inaccurate.Be easy to produce erroneous judgement.It is not corresponding with the bounce-back point of spring caps to contact stressed judgement critical value, thereby it is puzzled that the user is produced tactile feedback, is easy to produce erroneous judgement to whether having pushed button.The second, though input face can be very flat to make things convenient for handwriting input,, make the feel of handwriting input poor because the existence of spring caps causes the stressed having or not the local and unsmooth of spring caps of touch pad.Stressed inhomogeneous meeting makes the identification of person's handwriting produce uncontinuity, reduces the discrimination of handwriting input.The 3rd, spring caps directly contacts with touch pad, the frequent distortion of spring caps and the mobile wearing and tearing that can cause touch pad.
