Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method, a device and a terminal for amplifying and reducing, which are used for amplifying and reducing corresponding objects by pressing different pressure values of a touch screen, so that the operations of amplifying and reducing by a user are simpler and quicker, and the language of man-machine interaction is enriched. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a first embodiment of a zooming-in and zooming-out method according to the present invention. The method of zooming in and out can be applied to various terminals. The terminal includes, but is not limited to, a terminal with touch sensing, such as a smart phone, a tablet computer, a notebook computer, a palm computer, and a PAD. The operating system of the terminal may include, but is not limited to, an Android operating system, an IOS operating system, a Symbian operating system, a Black Berry operating system, a Windows Phone operating system, and the like. As shown in fig. 1, the method for zooming in and out can be used in a terminal having a touch screen, and includes the steps of:
s101, receiving a pressing operation signal of the touch screen.
Specifically, in the embodiment of the present invention, the touch screen detects a pressing operation performed by a user in a touch area of the touch screen, and acquires a pressing operation signal generated by performing the pressing operation. The touch area of the touch screen may be a part of the touch screen or the entire touch screen.
The touch screen may be a resistive touch screen or a capacitive touch screen. The resistive touch screen is composed of an Indium Tin Oxide (ITO) film, ITO glass, and some spacers (DOT) between them. When a finger or a pen tip presses the ITO film, the ITO film comes into contact with the ITO glass and voltage fluctuation occurs. The voltage variation is converted from an analog signal to a digital signal and the digital signal is then processed to obtain the (X, Y) position of the press. On the other hand, the capacitive touch screen is composed of silicon dioxide (SiO2), ITO, and glass. A smooth electric field is established on the surface of the glass. When a finger or a pen tip is in contact with the ITO, the variation of the electric field is detected by four sensors disposed at the four corners of the capacitive touch screen in order to locate its depression.
And S102, acquiring a pressure value corresponding to the pressing operation signal according to the pressing operation signal.
Specifically, the pressure sensor can acquire the pressure value of the pressure sensor through pressure sensing equipment such as the pressure sensor. The pressure sensor may be a resistance strain gauge pressure sensor, a semiconductor strain gauge pressure sensor, a piezoresistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, a resonant pressure sensor, or the like. Of course, the pressure value is obtained in the embodiment of the present invention, including but not limited to the manner described above. The pressure sensor can be arranged on the lower side of the touch screen or on the lower side of the panel of the touch panel screen, and the specific position of the pressure sensor is not limited in the invention as long as the pressure sensor can detect the pressure born by the touch panel.
Further, in step 102, while the pressure value corresponding to the pressing operation signal is obtained, the pressure value may also be displayed on the touch screen. The pressure parameters are visually displayed, so that the user can visually perceive the force and time acting on the mobile terminal at present, the operation of the user is reminded, and the operation experience of the user is improved.
S103, judging whether the pressure value is larger than a first preset pressure threshold value or not; if yes, amplifying a display object on the touch screen; and if not, reducing the display object on the touch screen.
Specifically, a first preset pressure threshold is prestored in the terminal and used for distinguishing different execution instructions after detecting the pressure value of the pressing operation of the user so as to enlarge or reduce the display object. As can be understood, when the pressing force of the user is greater than the first preset pressure threshold, the display object on the touch screen is enlarged; and when the pressing operation strength of the user is smaller than the first preset threshold, reducing the display object on the touch screen.
Further, receiving a pressing operation signal to the touch screen includes: and receiving a pressing operation signal for controlling the mark to be magnified and reduced for the display object displayed on the touch screen.
Furthermore, the display object on the touch screen is a picture displayed on the touch screen; receiving a pressing operation signal to the touch screen, comprising: and receiving a pressing operation signal of a picture displayed on the touch screen.
Of course, the size of the pre-stored first preset pressure threshold may be set by the user or by default according to different requirements of the user. For example, if the user is a small child, the force applied to the touch screen is relatively small when operating the mobile terminal, and a relatively small first preset pressure threshold may be set.
Further, the user's attribute may be determined by detecting biometric information of the user, and then the magnitude of the first preset pressure threshold may be set according to the user's attribute, without requiring the user to manually set according to different user's attributes. For example, when the user starts to operate, the user attribute is detected by collecting the biological characteristic information of the user, and when the user is detected to be a child, the size of the first preset pressure threshold value suitable for the operation habit of the child is automatically set. By determining the user attribute, the size of the first preset pressure threshold value to be set is further determined.
The biometric feature may be detected by recognizing a face, by a fingerprint of the user, by voice, or the like. The attribute of the user is determined in the embodiment of the present invention including but not limited to the above manner. The attribute of the user is the category of the user, male and female, or the age attribute of the user, child, adult, and old. Therefore, the user sets the pressure values with different sizes, so that different users have different user experiences when performing interface operation, and the usability of the mobile terminal is greatly improved.
According to the first embodiment of the zooming-in and zooming-out method, the corresponding object is zoomed in and zoomed out by pressing different pressure values of the touch screen, so that the zooming-in and zooming-out operations of a user are simpler and quicker, and the language of man-machine interaction is enriched.
