Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and terminal that realizes content scaling of touch screen.
Background technology
Touch-screen is as a kind of terminal input equipment, can make things convenient for, finish intuitively man-machine mutual, and therefore, on various terminals, especially on the mobile phone, touch screen technology has obtained using widely.Existing touch screen technology mainly contains two kinds, and a kind of is traditional single-point touches technology, and it can be controlled accurately to point target, realizes the accurate employing of data, and to handwriting input, particularly the Chinese character input has good effect; Another kind is the multiple point touching technology, is also referred to as multi-point touch technology, multiplex touch control technology, multiple spot induction technology, multiplex induction technology etc. simultaneously, and it can accept the input information from a plurality of points on the screen simultaneously, realizes the effect of a screen multipoint operation.
The user is using the screen of terminal, when carrying out browsing of relevant information such as the touch-screen of mobile phone, can wish usually information is zoomed in or out, and this just need have relevant solution to respond user's zoom request.Classification at touch screen technology, existing solution mainly contains two kinds, a kind of solution that is based on traditional single-point touches technology: it mainly is the mode of selecting by menu, provides menu to select for the user, thereby realizes the content of touch-screen is amplified or operation such as dwindled.The defective of this kind solution is: the user at first needs to transfer menu, operates accordingly according to the indication of menu then, and is more time-consuming like this, and operation is also more loaded down with trivial details.Another kind is based on the solution of multiple point touching technology: it mainly can point speed and the dynamics of slip by the induction user, thereby the gesture by application software identification user is made corresponding convergent-divergent and handled.The defective of this kind solution is: owing to adopt capacitive touch screen based on the existing terminal of multiple point touching technology more, its handwriting input effect is not as good based on the resistive touch screen of single-point touches technology, and the cost of multi-point touch panel is higher, unfavorable popularization.
Summary of the invention
Problem to be solved by this invention is, utilize the single-point touches technology, a kind of method and terminal that realizes content scaling of touch screen is provided, both avoided because the problem that the handwriting input performance descends and cost improves that use multiple point touching technology is brought has also been avoided because the problem of the complex operation that mode is brought that the use menu is selected simultaneously.
In order to address the above problem, the embodiment of the invention discloses a kind of method that realizes content scaling of touch screen, comprising:
When get access to the user touch-screen press operation press signal the time, gather the coordinate data of each touch point of the operation of picture camber line or the operation of setting-out section and the described signal that presses in time that described touch-screen continues;
In the time that described touch-screen continues, determine convergent-divergent type and corresponding convergent-divergent multiple to described touch-screen content that described user asks according to described coordinate data and the described signal that presses;
According to described definite convergent-divergent type and convergent-divergent multiple, described touch-screen content is carried out corresponding zoom operations.
Correspondingly, the embodiment of the invention also discloses a kind of terminal, comprising:
Acquiring unit is used for obtaining in real time the user presses operation at touch-screen the signal that presses;
Collecting unit is used for getting access to describedly when pressing signal when described acquiring unit, gathers the coordinate data of each touch point of the operation of picture camber line or the operation of setting-out section and the described signal that presses in the lasting time of described touch-screen;
Determining unit is used for according to the described coordinate data of described collecting unit collection and the described signal that presses determining convergent-divergent type and corresponding convergent-divergent multiple to described touch-screen content that described user asks in the time that described touch-screen continues;
Operating unit is used for convergent-divergent type and the convergent-divergent multiple definite according to described determining unit, and described touch-screen content is carried out corresponding zoom operations.
The present invention utilizes the single-point touches technology, press the related data of operation at touch-screen by gathering the user, the identification user is for the zoom request of touch-screen content, and realize zoom operations to the touch-screen content according to user's zoom request, both avoided because the problem that the handwriting input performance descends and cost improves of using the multiple point touching technology to bring, also avoided to make things convenient for, satisfy intuitively the user for the demand of content scaling of touch screen simultaneously owing to use the problem of the complex operation that mode is brought of menu selection.

Determining unit is used for according to the described coordinate data of described collecting unit collection and the described signal that presses determining convergent-divergent type and corresponding convergent-divergent multiple to described touch-screen content that described user asks in the time that described touch-screen continues;
Operating unit is used for convergent-divergent type and the convergent-divergent multiple definite according to described determining unit, and described touch-screen content is carried out corresponding zoom operations;
Described determining unit comprises:
First determining unit is used for the coordinate data according to described each touch point, determines the curve or the lines that are formed by described each touch point; According to the internal diameter varies of described curve, determine that described user is to the type of the zoom operations of asking of described touch-screen content; Or the contrast of the length that presets according to length and the described default unit of described lines, determine that described user is to the type of the zoom operations of asking of described touch-screen content;
Second determining unit, be used for according to described curve or lines and the described signal that presses in time that described touch-screen continues, determine that described user carries out the described speed that presses operation, according to the described ratio that presses speed and the speed that described default unit presets of operation, determine the convergent-divergent multiple of the determined convergent-divergent type of described first determining unit correspondence.
6. terminal as claimed in claim 5 is characterized in that, also comprises:
Default unit is used for preestablishing described user and presses the length of the formed lines of operation and preestablish the speed that described user presses operation.
7. terminal as claimed in claim 6 is characterized in that:
When the Changing Pattern of the internal diameter of the described curve that is formed by each touch point for from small to large the time, described first determining unit determines that described user's request carries out amplifieroperation to described touch-screen content;
When the Changing Pattern of the internal diameter of the described curve that is formed by each touch point for from big to small the time, described first determining unit determines that described user's request carries out reduction operation to described touch-screen content;
Or
When length that the length of the described lines that formed by each touch point presets greater than described default unit, described first determining unit determines that described user's request carries out amplifieroperation to described touch-screen content;
When length that the length of the described lines that formed by each touch point presets less than described default unit, described first determining unit determines that described user's request carries out reduction operation to described touch-screen content.
