Abstract

The embodiment of the invention discloses a method and device for adjusting the writing color of an infrared touch control machine and a computer readable storage medium. The method comprises the steps that whether a surface optical network of an infrared touch frame has a shielding area or not is judged; when a touch pen touches the surface of the touch screen, the infrared touch machine can rapidly collect a shielding area formed by the touch pen, and therefore the size value of a touch point is calculated; and a target color matched with the touch point is determined according to a pre-established corresponding relation between the size of the touch point and the color, and the writing color of the infrared touch control machine is adjusted to the target color. The size value of the touch point reflects the thickness of the touch pen. In practical application, a user can generate different writing colors by adopting the touch pens with different thicknesses to write, so that the scene application requirement of the user for quickly switching different colors is met, the thought of the user is effectively ensured not to be interrupted, and better product touch use experience canbe brought to the user.

Description

technical field [0001] The invention relates to the field of infrared sensing technology, in particular to a method, a device and a computer-readable storage medium for adjusting the writing color of an infrared touch machine. Background technique [0002] At present, when conducting interactive operations such as education or meetings on the infrared touch all-in-one machine, that is, the infrared touch machine, the infrared touch screen cooperates with the electronic whiteboard writing software to perform related touch writing. In order to meet different needs, users often use different colors to display written content, for example, use black display for conventional content, and use red display for highlighted content, etc. [0003] In order to distinguish the colors of the written content conveniently, the current technical means is to make corresponding selection menu items on the whiteboard writing software, and the user selects different line colors by clicking the m...
