Target object trigger method and system and wearable equipment based on virtual reality

Abstract

The invention relates to a target object trigger method and system and wearable equipment based on virtual reality. The method includes the following steps: tracing the user's point of regard in the human-computer interaction of virtual reality, and judging whether the user's head has the preset action when the point of regard rests on the interactive target objects. If so, the interactive operation set beforehand to the target object will be triggered; otherwise, the interactive operation will not be triggered. Action of the head is preset to trigger the target object, which makes human-computer interaction become more natural and independent, happen faster in real time without delay, and have strong operability.

Description

technical field [0001] The present invention relates to the field of virtual reality, in particular to a method, system and wearable device for triggering a target object based on virtual reality. Background technique [0002] The research goal of virtual reality (Virtual Reality) technology is to eliminate the boundaries between the human environment and the computer system, that is, in the virtual space provided by the computer system, people can use various sensory organs such as eyes, gestures, movements and language. interact directly with it. Human-computer interaction in virtual reality emphasizes the principle of "human-centered". For example, people are interested in applying gaze tracking to human-computer interaction. In the three-dimensional space of virtual reality, what you look at is what you want and what you want to interact with. [0003] All human-computer interaction needs to perform a "confirmation" action on the target object. For example, when using ...

Problems solved by technology

The first method needs the help of external devices, and does not really realize the human-centered approach; the second method is specifically that after the user locates the target object through line of sight scanning, the confirmation is triggered by judging that the time the line of sight stays on the target object reaches a certain length , the processing flow is: sight enters the target object - start timing - sight stays on the target object for a specified time (for example, 3 seconds), triggers "confirmation" of the target object and performs corresponding operations, if the line of sight moves out of the target object before reaching the specified time , then cancel the processing; using this method has certain disadvantages in some specific scenarios. For example, after the user scans the object through the line of sight, if the object is a button and the user wants to click the button immediately, the user still needs to wait until the specified time. For example, the actual click can only be performed after 3 seconds, the user cannot click immediately, and the real-time performance of human-computer interaction is poor; if the object is a picture, when the user just wants to view the picture but does not want to click the picture, he must move out of sight before the specified time, otherwise it will automatically Perform image-related operations, and the man-machine interaction is poor in manipulability; in addition, if the entire visible area of ​​the user is the target object, because the user's line of sight cannot leave the target object, it is not appropriate to judge whether to trigger a confirmation event by timing at this time , so the existing human-computer visual interaction method that judges and executes the confirmation action by timing is like a mouse without buttons, which cannot provide users with a natural and smooth sense of control, and has poor real-time performance and controllability
