Referring to fig. 1, in one aspect, the present invention provides a method for adjusting a window of an electronic whiteboard, including:
s101, receiving gesture actions, touch actions or key actions of an operator;
and S102, adjusting the display window position and the touch position of the android system and/or the non-android system of the electronic whiteboard according to the gesture action, the touch action or the key action.
The gesture action specifically refers to not touching the electronic whiteboard, an operator swings a gesture in front of the electronic whiteboard, if the gesture action is upward or downward, the camera device of the electronic whiteboard captures the gesture action and then recognizes the gesture action, the gesture action is compared with preset gesture action, and if the gesture action is the same as the preset gesture action, a preset instruction is executed, such as a display window position and a touch position of an android system and/or a non-android system of the electronic whiteboard is moved downwards, or the display window position and the touch position of the android system and/or the non-android system of the electronic whiteboard is pulled up. The specific gesture and command can be defined according to the requirement, and the present invention is not limited thereto.
The touch control action specifically refers to touch control of a screen of the electronic whiteboard, an operator performs touch control on the screen of the electronic whiteboard to generate a touch control track, if the touch control track is upward touch control or downward touch control, the electronic whiteboard captures the touch control action and then identifies the touch control action, compares the touch control action with a preset touch control action, and if the touch control action is the same as the preset touch control action, executes a preset instruction, such as moving a display window position and a touch control position of an android system and/or a non-android system of the electronic whiteboard, or pulling up the display window position and the touch control position of the android system and/or the non-android system of the electronic whiteboard. The specific command corresponding to the touch control action can be defined according to the requirement, and the invention is not limited.
The key action specifically refers to adjusting the electronic whiteboard through a remote controller or a system menu, for example, an up key or a down key is pressed, the electronic whiteboard identifies the key action, compares the identified key action with a preset key action, and executes a preset instruction if the identified key action is the same as the preset key action, such as moving the display window position and the touch position of an android system and/or a non-android system of the electronic whiteboard down, or pulling up the display window position and the touch position of the android system and/or the non-android system of the electronic whiteboard up. The specific command corresponding to the touch control action can be defined according to the requirement, and the invention is not limited.
Specifically, the non-android system comprises embedded OPS equipment and/or external computer equipment.
Referring to fig. 2, the electronic whiteboard touch frame of the present embodiment includes two touch interfaces, one is a USB interface, and the other is a UART interface or a USB interface. The electronic whiteboard is provided with a plurality of operating systems, an android system is used as a main framework, and the OPS equipment and the external computer equipment are embedded in the electronic whiteboard. One of the touch frames is specially used for an android system, and the other touch frame is used for the OPS device and the external computer device in a time-sharing mode (a USB output selection chip is switched according to a current channel).
The USB/serial port of the android system is communicated with the touch frame, and the initial position of the touch frame is adjusted according to an agreed protocol. In one embodiment, if full-screen touch is performed, the top right vertex is used as a starting point; if 2/3 is displayed, the touch will start from the position of the right 1/3, i.e. the top 1/3 is no touch and the bottom 2/3 is touch; if the display is a half-screen display, the touch starts from the position of the right side 1/2, i.e., the top 1/2 is not touched and the bottom is touched.
In the display system, the OPS equipment and the external computer system are accessed to the main board system through HDMI signal lines and are a signal source channel of the system; the android display system can also be considered as another source channel; since the processing on these two display systems is independent of each other for the system. Namely, the related operation window of the android APK and the operation window of the computer system belong to different display layers on the system; therefore, the control is performed separately for the position change.
In one embodiment, the gesture/touch is a 4-finger vertical pull-down/pull-up; when the touch screen is pulled down for the first time, the display is switched from full screen to downward shifting 1/3, and meanwhile, the control of the touch screen is also shifted downward 1/3; when the touch screen is pulled down for the second time, the position is switched from the 1/3 position to the 1/2 position, namely half-screen display is carried out, and touch control is also moved down to the 1/2 position; conversely, if the gesture/touch acts as a pull-up, the side gradually reverts to full screen display.
It should be noted that the above is only an embodiment, and the number of fingers is specifically adjusted each time by using several fingers, and the setting can be performed as needed.
Further, the menu of the electronic whiteboard system is opened for the operator to set, and the operator can set whether to support the control of the adjustment window.
In an actual application scene, most of the electronic whiteboards are used in an OPS/external computer channel, so that the window display position of the channel only needs to be controlled, and the android position does not need to be modified. Therefore, a switch is arranged in the system menu, and only signal source channels such as an OPS/external computer channel and the like are supported to be adjusted, or android adjustment is also supported. The operator can set the settings according to his own preference.
Specifically, the display displacement of the signal source channels such as the OPS/external computer channel and the like is adjusted by adjusting the display initial position of the system signal display window.
The display displacement of the android channel is processed by calling a multi-window display method of the android system; i.e. the APK is filled with a black background on top, while the window currently in use is squeezed to the lower second window for display.
Specifically, referring to fig. 3, when the electronic whiteboard system recognizes a gesture action, a touch action, or a key action, if only the non-android display window is supported to be moved, only the display window position of the signal source channel is adjusted, and meanwhile, the touch starting point of the path is adjusted; if the android mobile display window is supported, after the position of the display window of the signal source channel is adjusted, the android system multi-window function is called, the APK with a black background is displayed on the upper part, and the current APK is placed in the lower window for display; meanwhile, the touch position connected to the android path is also adjusted.
Referring to fig. 4, in a second aspect, a window adjusting apparatus for an electronic whiteboard includes:
an operator action receiving module 401, configured to receive a gesture action, a touch action, or a key action of an operator;
and a window adjusting module 402, configured to adjust a display window position and a touch position of the android system and/or the non-android system of the electronic whiteboard according to the gesture action, the touch action, or the key action.
