Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The embodiment provides a real-time recording storage method based on a touch screen, which is applied to terminal equipment such as an electronic white screen, a mobile phone terminal, a tablet terminal or a computer terminal, and executes a touch event and a transmission interaction action by using the touch screen on the terminal equipment. In this embodiment, an electronic whiteboard is taken as an example for description.
As shown in fig. 2, the record saving method of this embodiment specifically includes the following steps:
step S1: acquiring image attribute data sent by a touch screen in real time, and storing the image attribute data in a physical medium connected with the touch screen; and generating a corresponding mapping table according to the position relation of the image attribute data stored in the physical medium.
The image attribute data is track data generated when a touch event is performed on the touch screen; when a user touches the touch screen, corresponding image attribute data can be generated according to the track data of each operation of the user. Specifically, when a user writes a 'two' word on the touch screen, the first stroke of track data starts from the moment when a finger or other touch object contacts the touch screen, slides along the touch screen, finally, the track ends when the finger or other touch object leaves the touch screen, and when the track ends, the image attribute data corresponding to the track data can be correspondingly generated; and when the user writes a second pen of the 'two' character on the touch screen, generating corresponding image attribute data according to the track data during writing of the pen, so that each continuous touch event corresponds to the respective image attribute data. The image attribute data contains the characteristic points of the graph, and the picture image can be converted into a digital type to be stored.
In this embodiment, a physical medium is previously disposed outside the electronic whiteboard, and the physical medium may be a physical storage, as shown in fig. 1, the physical medium and the electronic whiteboard may be directly connected through a data line, or may be in bidirectional signal communication through a wireless network; and when the electronic whiteboard generates one image attribute data, the image attribute data is transmitted to the physical medium for storage, so that the generated data can be prevented from occupying a local memory of the electronic whiteboard. In addition, the image attribute data generated by the touch screen can be stored in a local memory of the touch screen in advance, the image attribute data stored in the local memory is transmitted to the physical medium in a centralized manner in a set period, and the uploaded data in the local memory is deleted; the set period can be determined according to the local memory capacity of the electronic whiteboard, and can be uploaded once at regular intervals or once when the local memory of the electronic whiteboard reaches a preset value.
And after the image attribute data are stored in the physical medium, generating corresponding and unique identification information for the position of each image attribute data stored in the physical medium, wherein the unique identification information of the image attribute data is used as an index in the mapping table. The unique identification information of the image attribute data is an identification number encoded by data generation time and an image characteristic numerical value, each image attribute data corresponds to the unique identification information, and the unique identification information is used as an index in the mapping table, so that the specific position of the image attribute data in the physical medium can be found according to the index when the mapping table is consulted.
The position of the image attribute data stored in the physical medium can be stored at will, and the position of the image attribute data in the physical medium can be quickly found according to a mapping table; in addition, the image attribute data can also be stored in the physical medium in a message queue manner, that is, the image attribute data is stored in the physical medium in a message queue manner according to the sequence of the data generation time of the image attribute data, so that when the image is displayed again in the following process, the corresponding image attribute data is output in a first-in first-out arrangement manner, and the time for consulting the mapping table is reduced.
Step S2: and receiving an operation image instruction sent by a terminal, searching image attribute data related to the operation image instruction from the physical medium according to the mapping table, and displaying the image attribute data.
The terminal comprises an electronic whiteboard, a mobile phone terminal, a tablet terminal or a computer terminal which are connected with the physical medium signal; and the user can call any image attribute data from the physical medium through another electronic whiteboard to display. The operation image instruction is generated according to actual operations such as images, image display sequences, display methods and the like which are displayed and selected by a user, the corresponding index in the mapping table is found according to the unique identification information of the image attribute data corresponding to the image selected by the user, the position of the image attribute data in the physical medium is found through the index, the corresponding image attribute data can be called according to the corresponding address information of the position and displayed on another electronic whiteboard, and the user can continue painting on the electronic whiteboard; the operations such as painting on the electronic whiteboard by the user are stored in the physical medium in the way, and the image is called out according to the way for displaying when the user needs to display again.
In this embodiment, a method for managing a pattern on an electronic whiteboard by using a physical medium is adopted, so that operations such as remote transmission interaction, real-time whiteboard, cancellation, redoing and the like between electronic whiteboards can be realized, consumption of a local memory on the electronic whiteboard is extremely low, and the electronic whiteboard has advantages in writing and performance.
