Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing.

[0030] A smart spatial augmented reality method that dynamically adjusts the user's cognitive load to improve the user's efficiency in performing a large number of complex tasks. This paper takes the quality control of a large number of solder joints on large mechanical parts such as automobile parts as an example to illustrate the specific implementation of the present invention.

[0031] In the field of machinery manufacturing, especially automobile manufacturing, spot welding is often used to connect different automobile sheet parts. There are thousands of welding spots in a car, and the welding spots of the parts need to be inspected to ensure the quality. In actual inspection work, usually not all solder joints are inspected, but a subset of solder joints on different parts are inspected in a certain order. Inspection methods usually include: visual inspection, ultrasoni...

Abstract

This invention provides an intelligent spatial augmented reality method capable of dynamically adjusting cognitive load of a user. The method comprises the steps of: firstly, establishing a spatial augmented reality stage; then, establishing a real-time user cognitive load measurement stage; and finally, establishing an intelligent spatial augmented reality stage. The method provided by the invention integrates a user cognitive load measuring method in a spatial augmented reality system, and measures the cognitive load level of the user in the spatial augmented reality system in real time. The spatial augmented reality system self-adaptively adjusts augmented information according to the real-time cognitive load level, so that the cognitive load of the user and the augmented information of the spatial augmented reality system are at a dynamically-balanced level. According to the current cognitive load level of the user, the method self-adaptively adjusts relevant elements of a task so as to better fit the practical working ability of the user; and thus, the work efficiency of the user is improved.

Description

technical field [0001] The invention relates to space augmented reality technology, in particular to an intelligent space augmented reality method for dynamically adjusting user cognitive load. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a technology that matches computer-generated virtual objects with the user's field of view in the physical world to integrate virtual objects into the physical world. The world is enhanced. Spatial Augmented Reality (SAR) is an augmented reality technology that uses digital projection technology to superimpose computer-generated virtual objects onto physical space. Spatial augmented reality systems based on projection systems use forward projection to directly project digital information onto the physical surface of an object, rather than displaying it on an image plane within the viewer's field of view. These spatially enhanced information relative to the user can help the user improve their understanding of...
