Computer-assisted sketch drawing method and system based on eye movement and brush stroke data

Abstract

The invention discloses a computer-assisted sketch drawing method and system based on eye movement and brush stroke data. The method includes the following steps that feature extraction is conducted on eye movement data and brush stroke data of a designer, and eye movement feature parameters and brush stroke feature parameters are obtained; the eye movement data and the brush stroke data are collected and obtained in a sketch drawing process by using a computer; whether the current state of the designer is a creative thinking state is judged according to the eye movement feature parameters and the brush stroke feature parameters; when the designer is in the creative thinking state, the next staring point position of the designer is judged according to the eye movement data, and an image stimulus source is shown at the position and assists the designer to conduct sketch drawing. According the eye movement and brush stroke information of the designer, the creative thinking state of the designer is identified and stimulated. By predicting staring point position changes of the designer, the image stimulus source position is optimized, and designing quality of the designer is improved.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to a method and system for computer-aided sketching based on eye movement and stroke data. Background technique [0002] Computer-aided sketch design combines the advantages of computer-aided design (CAD) with paper sketches, and uses computers to provide better support for sketch design, thereby improving the efficiency of sketch design and even stimulating the creativity of designers. [0003] Studies have shown that during the design process, pictures, videos and other content will stimulate the designer. In the existing computer-aided system, it is mainly to set a fixed interval to provide stimulation. This method will interfere with the design thinking and affect the designer. Getting inspired has a negative impact. [0004] Designers can be divided into two states in the process of sketching, one is the state of creative expression, and the other is the state of creative ...

Problems solved by technology

[0007] The above research mainly focuses on analyzing the user's attention area by analyzing the eye movement position, and interacting with the user according to the hidden information of the user's attention area. The latter invention further proposes to increase the validity judgment of the gaze position to filter out the user's unnecessary Command eye movement information, none of these studies involved judging the user's state of mind by obtaining eye movement information and predicting the user's next gaze point through the eye movement trajectory map
