Description
Technical Field
The invention belongs to the technical field of human-computer interaction, and particularly relates to a method and a device for operating a zooming function of an intelligent terminal by using a sliding-pressing gesture.
Background
In 2007, apple iPhone smartphone was produced, and in addition to the impression of a single 3.5 inch screen on the front, the greater visual impact comes from the fact that after the picture viewer is opened, the picture is zoomed in and out following the action of the fingers.
On the smart phone, two fingers of a user are gradually separated on the touch screen, the picture is enlarged, the picture is gradually closed, and the picture is reduced.
The multi-point touch is an interactive operation mode of multiple points or multiple users on the same display interface, and a single-point operation mode of a keyboard and a mouse is abandoned. The user can operate the touch screen by single-point touch through a single finger, and can also operate the touch screen by multiple points through double fingers or multiple fingers.
In the operation process, the fact that the zooming function of the intelligent terminal is operated only by utilizing the sliding gesture has two major disadvantages: firstly, the user often needs to repeatedly draw zoom gestures on the touch screen, and secondly, the operation objects (such as pictures, maps, characters, lines and graphs) are difficult to zoom finely.
The reason for the above disadvantages is that when the zooming speed is slow, the user often needs to repeatedly slide the two fingers on the touch screen for multiple times to achieve the desired zooming effect, which results in multiple times of zooming operations, strong intensity of zooming operations, and poor experience of zooming operations.
Therefore, when the zooming speed is high, any small change of the sliding speed of the two fingers of the user on the touch screen of the intelligent terminal can cause a large change of the zooming speed of the operation object.
Disclosure of Invention
The invention aims to solve the two defects existing in the current zooming gesture operation, and provides a method and a device for operating the zooming function of an intelligent terminal by using a sliding-pressing gesture.
The basic principle of the invention is as follows: and operating an operation object of the intelligent terminal to zoom in or zoom out at a constant speed by utilizing the sliding and pressing gesture of the double fingers of the user on the intelligent surface.
The operation objects include but are not limited to pictures, maps, pages, characters, lines and graphs; the sliding gesture is defined as a combined gesture of a sliding gesture and a long-press gesture, wherein the sliding gesture is used for determining whether the intelligent terminal is operated to enlarge or reduce the operation object, and the long-press gesture is used for operating the intelligent terminal to keep the operation object enlarged at a constant speed or keep the operation object reduced at a constant speed; the operation object is enlarged or reduced until the enlargement or reduction is limited as long as the user is pressing for a long time.
The operation object is enlarged or reduced at a constant speed, so that the condition of sudden enlargement or sudden reduction is avoided, each zooming state of the operation object can be presented to a user smoothly, and the user can control the zooming state of the operation object in a predictive and accurate manner.
The long-press gesture is added on the basis of the sliding gesture, the defect that the operation object can be zoomed only when the two fingers of the user slide continuously is overcome, the operation object can be controlled to be zoomed infinitely when the two fingers of the user press on the intelligent surface for a long time, and a plurality of sliding gestures of the two fingers of the user can be replaced by one long-press gesture of the two fingers of the user.
The method comprises the steps of operating rules, sliding gestures, operating flows, presetting a corresponding relation and zooming speed; the device comprises an intelligent surface, an intelligent terminal, an application program and wireless communication.
The technical scheme of the invention is as follows:

If the user slides and presses the gesture inwards along the stroke direction on the intelligent surface, the intelligent terminal is operated to reduce the operation object at a constant speed; and when the operation object of the intelligent terminal is reduced to the user expected value, the user fingers leave the intelligent surface, and the intelligent terminal is operated to stop reducing the operation object.
2. Sliding and pressing gesture

Further, the outward sliding gesture a1 is defined as that the user's fingers slide back on the intelligent surface first (as the distance between the fingers is increased), and after the sliding is finished, the user's fingers do not leave the intelligent surface, and then the user presses for a long time.
The inward swipe gesture a2 is defined as the user's fingers first swipe towards each other (as the distance between the fingers is closer and closer) on the smart surface, and after the swipe is finished, the user's fingers do not move away from the smart surface, and then perform a long-press action.
The user double fingers include but are not limited to two fingers of the left hand, two fingers of the right hand, one finger of each of the left hand and the right hand, and one finger of each of the two users of the same user; the sliding directions of the two fingers are opposite.

According to the technical scheme, the zooming function of the intelligent terminal is operated by using the sliding gesture, the user can control the operation object to zoom in or out at a constant speed when the user fingers slide on the intelligent surface, and if the user fingers are matched with the zooming proportion prompt, once the expected zooming proportion is reached, the user fingers can immediately leave the intelligent surface, so that the user can easily control the zooming precision of the operation object.
According to the technical scheme, the zooming function of the intelligent terminal is operated by the aid of the sliding gesture, and the operation effect is independent of the sliding distance of the two fingers of the user on the intelligent surface and only related to the staying time of the two fingers of the user on the intelligent surface. Therefore, the user can operate the intelligent terminal to control the operation object to zoom infinitely or to zoom to the limit position only by drawing one sliding and pressing gesture on the intelligent surface.
According to the technical scheme, the zooming function of the intelligent terminal is operated by using the sliding gesture, the sliding of the two fingers of the user on the intelligent surface only plays a role in direction prompting, and the direction prompting role is only used for determining whether the intelligent terminal is zoomed in or zoomed out. Therefore, the two fingers of the user can slide on the intelligent surface for a short distance, so that the physical strength of the user is saved, and the shielding area of the fingers of the user on the touch screen is reduced.
According to the technical scheme, the zooming function of the intelligent terminal is operated by the sliding-pressing gesture, and the intelligent surface of the sliding-pressing gesture and the display screen displaying the zooming effect can be separated by the two fingers of the user, so that the two fingers of the user can be far away from the operation object to remotely control the zooming function of the intelligent terminal, the two fingers of the user can not shield the display screen any more, and the user can observe the zooming scene of the operation object in a wider view.
