Embodiment Construction
[0041] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0042] The present invention provides an interactive system based on writing pens, including multiple writing pens, screens, cameras and processors, wherein:
[0043] Multiple writing pens, which are writing pens with special marks, are used for multiple users to operate the screen at the same time;
[0044] The camera is set above the screen to collect information on the screen;
[0045] The processor receives the information from the camera, and is used for detecting and tracking from which stylus the information is written.
[0046] Preferably, the plurality of writing pens are writing pens with digital labels.
[0047] Take two writing pens as an example below, an...

The present invention provides an interactive system and method based on writing pens. The interactive system includes multiple writing pens, screens, cameras and processors, wherein the multiple writing pens are writing pens with special marks for supplying Multiple users operate the screen at the same time; the camera is arranged above the screen to collect the information on the screen; the processor receives the information from the camera and is used to detect and track which writing pen the information is written from. The interaction method includes: calibrating the camera, and mapping the captured image to the corresponding position on the screen; using OCR character recognition technology to detect the above calibrated image; The connection lines form a continuous motion trajectory, and the purpose of human-computer interaction is realized according to the obtained motion trajectory. The interactive system and division method provided by the invention solve the problem that multiple writing pens operate on the screen simultaneously and are detected as one.
Description
technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to an interactive system and method based on a writing pen. Background technique [0002] In the existing process of human-computer interaction, due to the inaccurate position of the detection point caused by the unevenness of a single laser surface, the problem of interaction confusion when multiple motion trajectories are close together, multiple fingers or multiple writing pens are detected as one The problem caused the tracking results to be wrong. Contents of the invention [0003] The invention provides an interactive system and method based on a writing pen, which solves the problem that multiple motion trajectories are confused with each other when they are close to each other, and realizes the purpose of human-computer interaction according to the obtained motion trajectories. [0004] The present invention provides an interactive system ba...
