Embodiment Construction

[0056] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0057] Implicit interaction based on contextual information has been widely used and researched in virtual scenes. It is difficult to control the motion of a three-dimensional human hand in a virtual scene based on a two-dimensional plane image obtained by a common camera. During the operation process, human hands mostly use collision detection to select objects. However, the time complexity of collision detection is very high, especially in the virtual environment with complex scenes. In order to solve this problem, the present invention makes the following innovations: (1) proposes a new method for scene situation awareness; (2) utilizes the least squares method to fit parallel wire bundles, judges the intention of the user to operate, and adopts the bounding box The size implementation controls the Z variable to vary within a suitable range.

Abstract

The invention provides a human-computer interaction method based on scene situation awareness, which belongs to the field of human-computer interaction. The human-computer interaction method based on scene situation awareness uses the least squares method to fit the parallel wire bundle, judges the distance between the object in the parallel wire bundle and the straight line, and judges the user's operation intention according to the distance between the object and the virtual hand, and adopts the bounding box The size realizes the control of the Z variable to change within an appropriate range, and finally realizes the mutual interaction. The invention proposes to control the change of the Z variable based on the size of the bounding box, and obtains good results; when the user moves purposefully, the correct rate of fitting the straight line beam to predict the object the user wants to operate reaches more than 87%.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a method for human-computer interaction based on scene situation awareness. Background technique [0002] With the continuous development of computer science and technology, intelligent human-computer interaction has gradually become the dominant trend in the development of computing models. Especially after the concept of "Ubicomp" (ubiquitous computing) proposed by Mark Weiser in the 1990s, this trend is more obvious. In the interaction process, in order to reduce the burden of human operation and memory, it is necessary to expand the traditional interaction method and incorporate implicit human computer interaction (IHCI) on the basis of explicit human computer interaction. [0003] At present, implicit human-computer interaction has become an important research frontier in the field of interaction. Kaiyan of Swinburne University of Technology in Austral...
