Three-dimensional solid geometry drawing system based on pen type interaction and voice interaction

Abstract

The invention discloses a three-dimensional solid geometry drawing system based on pen type interaction and voice interaction. The three-dimensional solid geometry drawing system comprises a user interaction module, a recognition module, a command module and a geometry module. The user interaction module comprises an operation module and a display module; the operation module is used for acquiringoperation content of a user; the display module is used for displaying an identification result, a command conversion result and a three-dimensional solid geometry generation result of the user operation content in real time; the identification module is used for identifying the operation content of the user; the command module is used for converting the identification result of the operation content of the user into an executable command; the geometric module is used for constructing or modifying a three-dimensional geometric figure according to the executable command converted by the command module. The system can maintain the use habits of traditional classroom teaching to the maximum extent, improves the interaction efficiency, is high in operability and practicality, facilitates theimprovement of the spatial imagination capability of students, and stimulates the interest of the students in autonomous exploration and learning.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geometry rendering, in particular to a three-dimensional geometry rendering system based on pen interaction and voice interaction. Background technique [0002] The former Soviet educator Stoliar once pointed out that mathematics teaching is closely related to mathematics-related experimental activities, and it is necessary to combine experimental operations and observation verification to achieve the best teaching effect. Solid geometry, along with its difficult spatial imagination requirements, has become a knowledge point that many students find difficult to understand and learn. In traditional three-dimensional geometry education, teachers usually use a combination of blackboard drawing and physical models to display three-dimensional geometric figures. It is difficult for students to observe the whole picture of three-dimensional geometric figures or operate these models by hand. H...

However, the operation process of Cabri 3D relies heavily on the mouse and keyboard, and lacks the important function of marking the points of geometric figures with letters, which is not conducive to teachers' use in the teaching process.

At the same time, Cabri 3D cannot construct a three-dimensional figure according to the given constraints

[0004] In view of the insufficient functions of the three-dimensional geometry teaching software in the field of mathematics in middle schools, it is necessary to provide a three-dimensional geometry teaching software that can be operated conveniently and quickly, which can not only meet the needs of students to get started quickly, but also improve students At the same time, considering that in classroom teaching, teachers need to complete the teaching within the limited classroom time, so the software needs to have high interaction efficiency
