A 3D Target Selection Method Based on Progressive Expression of Object Attributes

Abstract

The invention discloses a three-dimensional target selection method based on the progressive expression of object attributes, which belongs to the field of human-computer interaction technology and includes the following steps: (1) extracting the shape, position and size attributes of all objects in the scene; (2) acquiring The user's gesture action extracts the shape, position and size attributes of the gesture trajectory; (3) executes the selection intention judgment based on the progressive expression, first performs the shape matching of the object outline and the gesture outline, and outputs the matching result when there is only one matching result. Match the object, otherwise perform position attribute matching; output the matching object when the matching result is unique, otherwise perform size attribute matching; finally get the matching object according to the size attribute matching. With the invention, the user can gradually and progressively express his choice intention to the system, which is more in line with human ability and habit, and achieves a more ideal balance between task difficulty and human ability.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a three-dimensional target selection method based on progressive expression of object attributes. Background technique [0002] Object selection technology is one of the core technologies in human-computer interaction. In human-computer interaction, before operating an object, it needs to be selected first. With the rapid development of virtual reality technology and augmented reality technology, the selection technology of three-dimensional objects in virtual environment has become a research hotspot in three-dimensional human-computer interaction due to its wide application value. [0003] As the first step of 3D interaction, 3D selection is the key research content in the field of 3D interaction. Today's mainstream 3D selection technology based on pointing metaphors and ray casting will greatly reduce the accuracy when selecting small objects, ...

Problems solved by technology

The natural shaking of human hands and the Heisenberg effect make it difficult for humans to complete precise pointing operations

[0004] Mainstream 3D selection techniques do not make rational use of human abilities and are therefore inherently flawed
