Problems solved by technology

[0002] The traditional touchpad or touch screen can only determine the position of the corresponding touch point for the object that touches the object, but cannot judge the size of the touched object, and the displayed touch track only has a specific thickness; when the user uses different shapes or different When thick and thin writing tools are used to write on the touchpad or touch screen, only touch writing traces of specific thickness can be obtained, but touch writing traces of different shapes and thicknesses can not be obtained according to the shape and thickness of the writing tool itself, resulting in poor user experience

Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0056] Refer to attached figure 1 , is a schematic flowchart of an embodiment of the method for displaying touch traces based on an infrared whiteboard provided by the present invention.

[0057] The touch track display method based on the infrared whiteboard includes:

[0058] Step 101: Continuously control the infrared emitting tube and the infrared receiving tube of the infrared whiteboard to scan the touched object from multiple angles according to the preset scanning frequency;

[0059] Step 102: Continuously receive multiple sets of multi-angle scanning data of the touching object at different times;

[0060] Step 103: According to each group of multi-angle scanning data, obtain the graphics of the contact parts b...

Abstract

The invention discloses a touch trace display method based on an infrared white plate. The method includes the steps of continuously controlling an infrared transmitting pipe and an infrared receiving pipe of the infrared white plate according to the preset scanning frequency to scan a touched object at multiple angles, continuously receiving multiple sets of multi-angle scanning data of the touched object at different moments, obtaining touched object figures at different moments according to the multiple sets of multi-angle scanning data, conducting smooth connection on the touched object figures at different moments according to the time sequence, and obtaining and displaying the touch trace of the touched object. The invention further discloses a touch trace display device based on the infrared white plate, and the infrared white plate applied to the touch trace display method or device based on the infrared white plate. By means of the touch trace display method and device and the infrared white plate, touch writing traces of different shapes and thicknesses can be generated according to shapes and thicknesses of writing tools, and the high-quality user experience that traces are instantly obtained when written is achieved.

Description

technical field [0001] The invention relates to the technical field of touch data processing, in particular to an infrared whiteboard-based touch track display method, device and infrared whiteboard. Background technique [0002] The traditional touchpad or touch screen can only determine the position of the corresponding touch point for the object that touches the object, but cannot judge the size of the touched object, and the displayed touch track only has a specific thickness; when the user uses different shapes or different When thick and thin writing tools are used to write on the touchpad or touch screen, only touch writing traces of specific thickness can be obtained, but touch writing traces of different shapes and thicknesses can not be obtained according to the shape and thickness of the writing tool itself, resulting in poor user experience . Contents of the invention [0003] In view of this, the object of the present invention is to propose a touch track dis...
