Further, the interactive electronic whiteboard at least has a sensing module for receiving a touch operation signal acting on a touch screen of the interactive electronic whiteboard; furthermore, the interactive electronic whiteboard is provided with a touch screen and a pressure sensor, pressure sensing data is detected through the pressure sensor, and touch width data and touch coordinate data are detected through the touch screen; furthermore, the pressure sensor and the touch screen are common pressure sensing devices and touch screen devices in the technical field of interactive electronic whiteboards. Further, in this step, the interactive electronic whiteboard may further detect whether a touch operation signal exists on the touch screen, and start to generate the touch trajectory when the touch operation signal exists; further, when the pressure data is smaller than the pressure set value, the touch track is not displayed, and when the touch width is larger than the width set value, the width of the touch track is displayed according to the width set value.
Obtaining a similarity value for each analog data according to comparison analysis operation based on the touch track; wherein, the comparison analysis operation uses Euclidean distance function or cosine distance function to calculate similarity; further, in this embodiment, the comparison analysis operation may be performed by using an image comparison algorithm commonly used in the art, for example, the comparison analysis operation may be performed by first forming a vector diagram from the touch trajectory (the touch trajectory is generally in a vector form, and therefore, a conversion manner is not limited), and then processing and analyzing the obtained vector diagram and the analog data according to a preset image comparison algorithm. Certainly, in each screening, comparison analysis needs to be performed on each analog data in the whole analog database, and then the screening is performed according to the similarity value to obtain the analog data with the similarity value within a certain range; further, the database of the mimics can be subjected to topological classification firstly, wherein the topological classification can be performed by first-level classification, second-level classification and … … to certain precise categories, for example, the databases can be classified into animal types, plant types and building types in first-level classification, the interior of the animal types also comprises second-level classification of fish types, crawling types, insect types and the like, and then the third-level classification is performed to find commonalities for subdivision; during comparison, first-class classification common comparison is performed, then second-class classification common comparison is performed, and finally accurate searching can be achieved only by comparing partial analog data. Furthermore, the comparison analysis operation is performed in real time, that is, the comparison analysis operation is performed as long as a touch track exists on the interactive electronic whiteboard.
Further, when the euclidean distance function processes the feature vector between the touch trajectory and the simulation data, the euclidean distance function may be expressed as the following formula:

Screening to obtain a plurality of approximate analog data; wherein, the analog data with the similarity value larger than a preset value is used as approximate analog data; specifically, the predetermined value is determined according to the used distance function, for example, when the similarity values are calculated by using the euclidean distance function, the first predetermined ratio of the maximum similarity value among all the used similarity values can be used as the predetermined value, and it can be ensured that a certain amount of approximate simulation data is obtained by screening. When the cosine distance function processes the feature vector between the touch track and the analog data, the predetermined value is preferably 0.7-0.9, and more preferably 0.8, so that the reliability of the screened analog data can be ensured.
