A method for automatically correcting the cursor and an intelligent device

Abstract

The invention belongs to the field of computer technology. The invention provides a method for automatically correcting a cursor and an intelligent device. The method includes the following steps: projecting a preset cursor on a book page, and monitoring the projection direction and length and width of the preset cursor on the book page in real time Ratio: when the projection direction of the preset cursor on the book page is not the positive direction and / or the aspect ratio is not within the preset aspect ratio range, it is determined that the book page is placed on a non-horizontal platform. When the book page is placed on a non-horizontal platform, adjust the projection direction and aspect ratio of the preset cursor so that the projection direction of the preset cursor on the book page is the positive direction and the aspect ratio is at the preset length Wide scale range. The invention realizes automatic correction of the cursor so that the cursor does not deform, assists the user to more intuitively judge whether the content to be aligned is in the recognition area, can effectively improve the user's use efficiency, and enhance the user experience.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for automatically correcting a cursor and an intelligent device. Background technique [0002] In the process of doing homework, primary and middle school students often use question-searching software or word-searching software to assist their learning in order to improve homework efficiency. The current common question search software or word search software uses the standard line displayed on the screen to assist the user to more accurately align the topic or word to be queried. Although this can meet the basic needs of the user, the standard line floating on the screen The auxiliary lines cannot form a good correspondence with the topics or words in the textbook, so the user experience is not good. [0003] In the current optimization scheme, cursors of various shapes can be projected on the textbook through the laser light near the camera of the device, such as a...

Problems solved by technology

The current common question search software or word search software uses the standard line displayed on the screen to assist the user to more accurately align the topic or word to be queried. Although this can meet the basic needs of the user, the standard line floating on the screen The auxiliary line cannot form a good correspondence with the topics or words in the textbook, so the user experience is not good

[0003] In the current optimization scheme, cursors of various shapes can be projected on the textbook through the laser light near the camera of the device, such as a cross cursor, a word cursor, etc., to help users more intuitively judge whether the content to be aligned is in the recognition area, but This solution of projecting the cursor through a fixed laser light has relatively high requirements for the user's operation. When the device and the textbook are in a non-parallel state, the cursor will be deformed to a certain extent because the angle between the projected light and the textbook plane is less than 90 degrees, such as The cross cursor will be elongated, which will directly affect the user experience
