Touch screen mobile terminal image quick comparison interaction method

Abstract

The invention discloses a touch screen mobile terminal image quick comparison interaction method. The method comprises the steps that a first layer is viewed; a second layer is added above the first layer for overlapping, then registration is performed according to projection coordinates, the first layer and the second layer are completely overlapped, and an overlapping layer is formed; when a user presses a screen for time exceeding preset hidden pressing time, a mobile terminal system modifies the transparency of the second layer till the second layer has a hidden effect, and the first layeris viewed through the second layer; and when the mobile terminal system judges that a finger makes contact with the mobile terminal screen, the overlapping layer can be dragged to move. Through the touch screen mobile terminal image quick comparison interaction method, more clearer content can be displayed on the screen, the operable range is enlarged, more convenience is brought to comparison for visual interpretation, screen operation cost caused by pressing and dragging is reduced, and discomfort caused by friction between the finger and the screen is relieved.

Description

technical field [0001] The invention relates to the technical field of image interaction at a mobile terminal, in particular to a method for quickly comparing and interacting images at a mobile terminal on a touch screen. Background technique [0002] In the field of remote sensing, visual interpretation is a kind of remote sensing image interpretation, also known as visual interpretation or visual interpretation, which is the inverse process of remote sensing imaging. It refers to the process in which professionals obtain specific target object information on remote sensing images through direct observation or with the help of auxiliary interpretation instruments. [0003] Most of the current visual interpretation of remote sensing images is carried out through remote sensing industry application software, and they are all suitable for personal computers. The visual interpretation of satellite images can be displayed on the large screen of the PC and dragged and dropped by ...

Problems solved by technology

On a mobile terminal screen below 6 inches, it is necessary to perform zoom-in gestures, click gestures, slide gestures, and press-and-drag gestures. The operable range of the screen has been reduced by more than half, and the range for users to perform gesture operations will become smaller and smaller. If users need to perform visual interpretation operations, they need to use multiple different gestures in a small area of ​​the screen to complete the operation. The user experience is not good. good

And the visual interpretation focuses on quickly obtaining the difference of the image through simple operations, and should not focus on too many gesture operations, and there is a high operation cost of pressing and dragging, and the user's fingers are on the screen. Press and drag back and forth, the friction between the finger and the screen will cause a lot of discomfort, and even hurt the user's fingers

Pressing and dragging left and right in a small area of ​​the screen is not flexible enough. The screen itself is small, and there is not much content that can be displayed. Users should try their best to drag the map on the small screen to move the undisplayed image content to the screen. within the visual range, but after the existing method of rolling the screen, the screen is operable and the displayable range is even smaller

And the roller shutter shaft in the middle will also cause visual discomfort and affect the viewing of image content, especially on small screens
