Problems solved by technology

[0003] However, there are still many problems in the hand perception interaction in the current virtual-real fusion system: (1) Only by establishing a mapping relationship between the identifiable hand movements and the teacher's teaching actions can the corresponding functions be performed, which increases the difficulty of user mental transformation; (2) Haptic perception involves human kinesthetic and tactile elements, requiring the use of a variety of proprietary vibration and force feedback devices, which increases the complexity of implementation
These defects limit the acquisition of teachers' immersion in the three-dimensional comprehensive teaching field

Abstract

The invention belongs to the field of teaching application of information technology, and provides a teacher hand sensing interaction method in a three-dimensional comprehensive teaching field, which comprises the following steps: (1) sensing a hand posture; (2) simulating touch sensing; and (3) generating sensing interaction. According to the method, generation of visual and tactile sensing interaction in a three-dimensional comprehensive teaching field is facilitated, and deep fusion of technologies and teaching activities is promoted.

Description

technical field [0001] The invention belongs to the teaching application field of information technology, and more specifically relates to a hand perception interaction method of a teacher in a three-dimensional comprehensive teaching field. Background technique [0002] With the help of 5G, artificial intelligence, virtual reality, digital sensing and other emerging technologies to build a three-dimensional comprehensive teaching field, create a new teaching scene that is highly integrated with physical space and cyberspace and centered on learners. With the help of the virtual-real fusion teaching situation created by the three-dimensional comprehensive teaching field, the vision and hearing of teachers and students can be brought from reality into the virtual world. Through interactive devices such as headsets, handles, and motion capture, teachers can independently browse the virtual scene of the three-dimensional comprehensive teaching field to satisfy their visual and ...
