Embodiment Construction

[0048] A method and system for computer-aided sketching based on eye movement and stroke data of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Such as figure 1 As shown, a method of computer-aided sketching based on eye movement and stroke data, including the following steps:

[0050] (1) Feature extraction is performed on the designer's eye movement data and brushstroke data respectively to obtain eye movement feature parameters and brushstroke feature parameters; the eye movement data and brushstroke data are collected during the sketch drawing process using a computer.

[0051] The collection of eye movement data is realized through the eye tracker, and the infrared camera in the eye tracker is used to collect the eye movement data of the designer; the collection of stroke data is carried out through the digital board of the drawing tool, and the collection of eye movement data and stroke data is carried out si...

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 ...
