Abstract
A touch response method, device, interactive white board and storage medium are provided. The method acquires, based on infrared touch detection, touch operation data generated correspondingly by a current contact point on a writing interface. The touch operation includes a first touch operation and a second touch operation, and the first touch operation and the second touch operation are distinguished by the touch area. When there is only one touch operation, it confirms to enter a writing mode or an erasing mode according to a type of the touch operation.
Claims18
A touch response method, comprising:
- receiving one or more touch operations and acquiring touch operation data generated based on a current touch operation,
- wherein the current touch operation comprises a first touch operation and a second touch operation,
- wherein the touch operation data comprises a touch area, the touch area of the first touch operation is not greater than a preset area threshold, and the touch area of the second touch operation is greater than the preset area threshold, and
- wherein the method further comprises one or more of the following:
- when the first touch operation is received first, entering a writing mode;
- when the first touch operation is received first and the second touch operation starts to be received during a touch process of the first touch operation, maintaining the writing mode;
- when the second touch operation is received first, entering an erasing mode;
- after the second touch operation is received first and the erasing mode is entered, starting to receive the first touch operation during a touch process of the second touch operation, and when a moving distance of the second touch operation from an initial time of receiving the second touch operation to an initial time of receiving the first touch operation is not greater than a first distance threshold, performing mode switching to enter the writing mode from the erasing mode;
- and
- after the second touch operation is received first and the erase mode is entered, starting to receive the first touch operation during the touch process of the second touch operation, and when the moving distance of the second touch operation from the initial time of receiving the second touch operation to the initial time of receiving the first touch operation is greater than the first distance threshold, maintaining the erasing mode.
An interactive white board, comprising:
- a memory storing computer-readable instructions;
- and
- a processor coupled to the memory and configured to execute the computer-readable instructions, wherein the computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:
- receiving one or more touch operations and acquiring touch operation data generated based on a current touch operation,
- wherein the current touch operation comprises a first touch operation and a second touch operation,
- wherein the touch operation data comprises a touch area, the touch area of the first touch operation is not greater than a preset area threshold, and the touch area of the second touch operation is greater than the preset area threshold and
- wherein the operations further comprise one or more of the following:
- when the first touch operation is received first, entering a writing mode;
- when the first touch operation is received first and the second touch operation starts to be received during a touch process of the first touch operation, maintaining the writing mode;
- when the second touch operation is received first, entering an erasing mode;
- after the second touch operation is received first and the erasing mode is entered, starting to receive the first touch operation during a touch process of the second touch operation, and when a moving distance of the second touch operation from an initial time of receiving the second touch operation to an initial time of receiving the first touch operation is not greater than a first distance threshold, performing mode switching to enter the writing mode from the erasing mode;
- and
- after the second touch operation is received first and the erase mode is entered, starting to receive the first touch operation during the touch process of the second touch operation, and when the moving distance of the second touch operation from the initial time of receiving the second touch operation to the initial time of receiving the first touch operation is greater than the first distance threshold, maintaining the erasing mode.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- receiving one or more touch operations and acquiring touch operation data generated based on a current touch operation,
- wherein the current touch operation comprises a first touch operation and a second touch operation,
- wherein the touch operation data comprises a touch area, the touch area of the first touch operation is not greater than a preset area threshold, and the touch area of the second touch operation is greater than the preset area threshold, and
- wherein the operations further comprise one or more of the following:
- when the first touch operation is received first, entering a writing mode;
- when the first touch operation is received first and the second touch operation starts to be received during a touch process of the first touch operation, maintaining the writing mode;
- when the second touch operation is received first, entering an erasing mode;
- after the second touch operation is received first and the erasing mode is entered, starting to receive the first touch operation during a touch process of the second touch operation, and when a moving distance of the second touch operation from an initial time of receiving the second touch operation to an initial time of receiving the first touch operation is not greater than a first distance threshold, performing mode switching to enter the writing mode from the erasing mode;
- and
- after the second touch operation is received first and the erase mode is entered, starting to receive the first touch operation during the touch process of the second touch operation, and when the moving distance of the second touch operation from the initial time of receiving the second touch operation to the initial time of receiving the first touch operation is greater than the first distance threshold, maintaining the erasing mode.
