Detailed Description
The invention will be further described with reference to the following detailed drawings, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the invention easy to understand.
The invention is implemented on the basis of AR glasses or smart phones/tablets, which must be provided with associated image capturing means for capturing the display content and for capturing the eye movements of the user.
As shown in fig. 1, an AR labeling method based on display content includes the following steps:
s1, analyzing display contents to be marked, extracting the marked contents in the display contents, performing AI arrangement, automatically dividing according to the integrity of the marked contents, such as a word, a sentence, a single graph and other units with complete meanings, editing the units into a plurality of trigger sets, performing background preloading marking on the contents of the trigger sets by a parallel network, caching the marked contents in a computer memory, converting the whole display contents into two-dimensional plane data, converting the plurality of trigger sets into coordinate sets according to original corresponding positions on the display contents, and embedding the coordinate sets in the positions corresponding to the two-dimensional planes;
s2, capturing a gazing focus of a user by an eyeball tracking module of the equipment, converting a gazing focus position signal into a coordinate signal on a two-dimensional plane so as to judge whether the gazing focus coincides with a trigger set, and when the time of the gazing focus on the trigger set exceeds a set time, highlighting display contents mapped by the trigger set, wherein the display contents are used for indicating that the display contents can be marked, after the highlighting lasts for the set time, the highlighting effect is hidden, and when the time of the gazing focus on the trigger set is lower than the set time, the display contents do not react, so that misoperation caused by jumping of a sight is prevented;
s3, capturing finger gesture information by an image capturing module of the device, capturing and tracking the peripheral outline of the finger through an image recognition technology, determining a plurality of measuring points on the peripheral outline based on a template matching algorithm and based on an artificial neural network, determining coordinates on a two-dimensional plane by the plurality of measuring points at the moment, recognizing the measuring points at the top end of the finger fingertip as invisible virtual cursors, enabling labels on the corresponding trigger set to enter a pre-loading state when the virtual cursors stay on the trigger set, loading and displaying the label content after the trigger set stays for a set time, and hiding the label content after the virtual cursors leave the trigger set for a set time;
s4, when the gazing focus and the virtual cursor captured by the eyeball tracking module are concentrated on one trigger set, namely, under the condition of no consideration of depth, the two-dimensional coordinates of the gazing focus and the two-dimensional coordinates of the virtual cursor are both positioned in the coordinate set of the trigger set, and at the moment, marking contents are immediately displayed in the area near the display contents mapped by the trigger set;
and S5, repeating the step S2 or S3 when one of the gazing focus and the virtual cursor leaves the trigger set, and restoring the display content to be the same when the gazing focus and the virtual cursor leave the trigger set.
The annotated content includes graphics, animations, video, text and icons.
And S2, setting time of focusing the gazing focus on the trigger set is 3-5S, setting time of highlighting display duration is 1-3S, and after the highlighting effect is hidden, the trigger set receives highlight wakeup of the gazing focus again after 10-15S.
By adopting the scheme, when the reading or watching speed of the user is comprehensively considered and the focusing focus is concentrated at about 4s, the influence of short sight line deviation is avoided, the corresponding labeling time is not delayed too much, and meanwhile, the setting of the dormancy time after the highlight effect is hidden is to prevent the user from repeatedly carrying out highlight to disperse the attention of the user when the user focuses on watching a section of display content.
In S2, the highlighted content is quickly converted into the marked content to be displayed through the remote operation equipment, and the specific principle is that the remote operation equipment performs active marking operation through triggering or gestures at the moment under the highlight state of the displayed content, so that the content marking can be conveniently and quickly completed.
In S3, the setting time of the virtual cursor staying on the trigger set is 5-8S, the setting time of the virtual cursor leaving the trigger set is 1-3S, the setting time of the triggering time of the virtual cursor is slightly longer than the triggering time of the fixation focus, the finger gesture is prevented from being accidentally shot by the image shooting module and immediately triggering the mark to influence the sight line, and meanwhile, the effect of marking the target display content can be achieved after a period of time.
In S3, the captured finger gesture information does not comprise the gesture information of the thumb, because in a normal use scene, a user does not need to use the thumb when reading and understanding with the assistance of fingers, and generally only uses the index finger and the middle finger, and the ring finger and the little finger are contracted, the method can shield the gesture information capture of the thumb, and prevent the gesture information of the thumb from mistakenly touching irrelevant display content labels.
