As shown in FIG. 2a, a method for controlling information display according to an embodiment of the present invention specifically includes the following operations:

S201. Determine a capture reference area set in advance on the tablet, and determine a gesture reference point in the capture reference area.

In this embodiment, the capture reference area may be specifically understood as a gesture that the user can perform, and the camera may trigger an area for capturing the gesture operation. It can be understood that the tablet is specifically used for the user's board operation on the teaching content under normal conditions. If the corresponding capture reference area is not set, the embodiment may not be able to judge when the capture of the user gesture operation is started.

In this embodiment, the set capture reference area can be monitored in real time by the camera. When the user detects that there is a certain operation in the capture reference area, it is equivalent to triggering the capture operation of the camera on the gesture operation. Therefore, this step specifically performs the gesture. The specific location of the capture reference area is determined prior to operation. Generally, the entire writing board can be set to capture the reference area, and the entering display control can be triggered by recognizing the gesture triggered by the user; this embodiment preferably sets a partial area of the writing board as the capturing reference area.

In this embodiment, the gesture reference point can be specifically understood as a reference point required for performing a specific analysis on the gesture operation of the user. Based on the gesture reference point, a specific operation trajectory formed by a specific operation direction of the gesture operation or the like can be determined. The embodiment preferably sets the center point of the capture reference area to Gesture reference points, and can be identified by highlighting marks for easy identification by the user and the camera.

S202. Monitor the capture reference area in real time, and capture a gesture operation performed by the user with the gesture reference point as a starting point.

After determining the capture reference area and the gesture reference point based on the above steps, this step monitors the capture reference area through the camera image in real time, and captures the user's gesture reference point as a starting point when determining that the user's hand appears in the capture reference area. Gesture operation, thereby forming a video or continuous image frame containing gesture operations.

S203. Analyze operation information of the gesture operation relative to the gesture reference point, and determine a gesture control instruction corresponding to the operation information based on a preset information instruction mapping table.

In this embodiment, the captured gesture operation may be identified and analyzed to determine the operation information that the gesture operation actually corresponds to. In this embodiment, the operation information preferably includes: an operation direction and a number of consecutive operations. Illustratively, it can be analyzed whether the gesture operation is specifically an upward operation or a downward operation with respect to the gesture reference point, or is it a leftward operation or a rightward operation. Generally, the gesture operation of the user is usually a sliding operation, whereby the number of consecutive operations of the gesture operation can be further determined, such as a single sliding up or two consecutive upward slidings.

In this embodiment, the mapping relationship between the operation information and the set gesture control instruction may be constructed in advance, thereby forming an information instruction mapping table. Therefore, based on the information instruction mapping table and the operation information determined in this step, the location instruction mapping table may be searched. The gesture control instruction that the determined operation information actually corresponds to. It can be understood that different gesture control instructions in the location instruction mapping table contain different control information.

In this embodiment, according to the actual display requirement of the user for the teaching information display, a gesture control instruction including different display control information is set. Preferably, the requirement for displaying the last teaching information is performed according to the user's needs, thereby setting a previous state display instruction including controlling the display of the previous state teaching information; The user needs to perform the next teaching information display requirement, thereby setting a next state display instruction including controlling to display the next state teaching information; and automatically displaying the content according to the user's required information, thereby setting the control teaching information The automatic display instruction displayed forward or sequentially; in addition, the need to convert the file of the displayed information according to the user's needs, thereby setting a replacement display instruction including controlling the conversion display of the different teaching information windows.

Based on the above settings, the present embodiment may preferably consider that the gesture control instruction includes: a previous status display instruction, a next status display instruction, an upward automatic display instruction, a downward automatic display instruction, a forward switching display instruction, and a backward direction. Switch display instructions. In the present embodiment, the following S204 to S09 respectively give specific operations when the operation control command performs different information display control.

It should be noted that the specific mapping relationship between the operation information of the gesture operation and the gesture control instruction may be: when the operation information is a single sliding upward relative to the gesture reference point, the corresponding gesture control instruction may be the previous state display. When the operation information is a single sliding downward relative to the reference point of the gesture, the corresponding gesture control instruction may display the instruction for the next state; when the operation information is the relative gesture reference point, the corresponding gesture control instruction is continuously slid twice The instruction may be automatically displayed upward; when the operation information is slid downward twice in the relative gesture reference point, the corresponding gesture control instruction may be an automatic display instruction downward; when the operation information is a single sliding of the relative gesture reference point to the left The corresponding gesture control instruction may be a forward switching display instruction; when the operation information is a single sliding to the right relative to the reference reference point, the corresponding gesture control instruction may switch the display instruction backward.

S204. If the gesture control command is the previous state display command, the control setting display terminal displays the previous teaching information corresponding to the previous state of the currently displayed teaching information.

Illustratively, in the teaching process, it is assumed that the operation information corresponding to the gesture operation based on the gesture reference point in the tablet capture reference area is an upward single slide, and the actual determination is based on S203. The corresponding gesture control command is the previous state display instruction.

At this time, it may be determined to set the currently displayed teaching information on the display terminal, and determine the last teaching information corresponding to the previous state of the currently displayed teaching information, and then control the setting display terminal to convert the displayed content into Last teaching information.

S205. If the gesture control instruction is the next status display instruction, the control setting display terminal displays the next teaching information corresponding to the next state of the currently displayed teaching information.

Exemplarily, the operation of this step is similar to the operation of S204 described above, that is, after determining that the gesture control instruction is the corresponding next state display instruction, first determining the currently displayed teaching information on the setting display terminal, and determining the The next display state of the teaching information specifically corresponds to the next teaching information, thereby controlling the setting display terminal to convert the content to be displayed into the next teaching information.

S206. If the gesture control command is an upward automatic display instruction, the control setting display terminal automatically displays the teaching information before the currently displayed teaching information in reverse order at the set rate.

Specifically, in the teaching process, when the user (teacher) wants to present the teaching information to the presenter, if the gesture operation of the next state display instruction is frequently performed, the user experience is also reduced, and the user can directly pass the gesture. The information in the trigger gesture control instruction automatically displays an instruction, wherein the information automatic display instruction can be further refined into an upward automatic display instruction and a downward automatic display instruction according to different gesture operations.

In this step, when the operation information of the user gesture operation is determined to be scrolled up two times in succession, the teaching information before the currently displayed teaching information is automatically displayed according to the upward automatic display instruction control setting display terminal. The embodiment can control the teaching information to jump forward and display based on the preset jump rate. This step displays the teaching information before the currently displayed teaching information, which can facilitate the listener to deepen the consolidation of the taught teaching information.

It should be noted that, in this embodiment, the display terminal can be stopped by automatically triggering the upward automatic display instruction to stop the automatic display of the teaching information. Specifically, when it is determined that the user performs the gesture operation corresponding to the upward automatic display instruction during the automatic jump display of the teaching information, it may be considered that the stop operation of the automatic display function is triggered, thereby ending the automatic advancement of the teaching information. display.

S207. If the gesture control instruction is a downward automatic display instruction, the control setting display terminal automatically displays the teaching information after the currently displayed teaching information in a sequence at a set rate.

Exemplarily, the operation of this step is similar to the operation of the above S206, that is, after determining that the gesture control instruction is the corresponding downward automatic display instruction, the display terminal can also be set according to the downward automatic display instruction to control the currently displayed teaching. The teaching information after the information is automatically displayed, thereby controlling the setting display terminal to automatically control the backward jump and display of the teaching information at the set rate.

Similarly, when it is determined that the user performs the gesture operation corresponding to the downward automatic display instruction during the automatic jump display of the teaching information, it can be considered that the stop operation of the automatic display function is triggered, thereby ending the backward automatic of the teaching information. display.

S208. If the gesture control command is a forward switching display instruction, the control setting display terminal displays the teaching information in the previous teaching information window adjacent to the currently displayed teaching information window.

It should be noted that in general, multiple teaching files can be opened at the same time on the display terminal, and displayed in a side-by-side window. In the teaching process, it is necessary to switch between multiple teaching files, and the existing methods also need to be performed. Directly operate the setting display terminal to switch between teaching file windows.

In this embodiment, the switching between the teaching file windows can also be realized by the gesture operation of the user on the writing board. Specifically, for the switching of the teaching file window, the embodiment sets the forward switching display instruction and the backward switching display instruction, that is, when the user needs to switch from the current teaching information window to the adjacent one. When teaching the information window, a gesture operation including the leftward word slide operation information may be performed on the tablet, whereby the operation of this step may be implemented after determining the gesture operation instruction of the gesture operation based on S204.

S209. If the gesture control command is to switch the display instruction backward, the control setting display terminal displays the teaching information in the next teaching information window adjacent to the currently displayed teaching information window.

Exemplarily, the operation of this step is similar to the operation of S208 described above. When the user needs to switch from the current teaching information window to the adjacent teaching information window, a gesture including the rightward sliding operation information may be performed on the writing board. Operation, thereby determining that the corresponding gesture control instruction is a sequential switching instruction based on S204, and then switching the current teaching information window to the next teaching information window based on the operation of the step, and in the latter teaching information window Teaching information is displayed.

A control method for information display provided by the second embodiment of the present invention specifies a process of determining a gesture control command, and embodies a control process of display control corresponding to different gesture control commands. By using the method, the teacher can control the display content of the setting display terminal through the writing board without leaving the writing board of the teaching board; the direct operation of the setting display terminal by the teacher or the remote operation by the wireless remote control pen is avoided. The real-time effective control for setting the display content of the display terminal is realized; thereby effectively improving the teaching efficiency of the teaching person, thereby improving the user experience of the intelligent teaching device.
