Method is described in further detail.
A kind of children's reading analysis system based on eye movement characteristics of the invention, referring to FIG. 1, including host computer 1, aobvious
Show device 2, eye tracker 3, high-definition camera 4 and plate vice screen 5, host computer 1 configures children's reading analysis system, and executes following
Step: B, being presented an animation on a display 2, child attention be attracted on display screen, and utilizes moving on display screen
Draw the blinkpunkt for correcting the children；C, after blinkpunkt correction, the audio material recorded is played by peripheral equipment, simultaneously will
Meet children's knowledge experience draws this by the display 2 with an independent picture, completely and in sequence presents
To the children；D, the oculomotor data of children are acquired using the eye tracker 3 on display 2, and data is uploaded and are saved extremely
On host computer 1；E, host computer 1 calculates time scale, the text that every page children watch attentively according to the eye movement data
Area's fixation time ratio and picture region fixation time ratio；F, according to children on picture on each point the length of residence time and
Eye movement thermal map is drawn out, and the children's reading situation is obtained according to the analysis of eye movement thermal map；Display 2 is connect with host computer 1,
Eye tracker 3 is installed on a display 2, and 2 top of display is equipped with high-definition camera 4, and high-definition camera 4 passes through with plate vice screen 5
Network connection, plate vice screen 5 receive and show the data that host computer 1 is handled.Sound equipment 6 is connected on the host computer 1.Institute
It states and is connected with printer 7 on host computer 1.
A kind of children's reading analysis method based on eye movement characteristics of the invention, please refers to Fig. 1-3, including
A, start host computer 1；Children's reading analysis system is opened, into system；Children can be allowed to be sitting in parent's knee
On, it is greater than 65 centimetres apart from display screen, makes display screen center and children's eyes in the same horizontal line.
B, an animation is presented on a display 2, child attention is attracted on display screen, and using on display screen
Animation corrects the blinkpunkt of the children；
C, after blinkpunkt correction, the audio material recorded is played by peripheral equipment, while the children will be met and known
Knowledge experience draws this by the display 2 with an independent picture, completely and is in sequence presented to the children；
In this way, after blinkpunkt corrects, by the audio material recorded before device plays, audio data as shown in figure 3,
For drawing this " this sequentially can cannot wrong ", this draws the knowledge experience that this content meets child, and pandect is total to including cover including
Page 13, every page is produced individually into a picture, completely and is in order presented to children.
D, the oculomotor data of children are acquired using the eye tracker 3 on display 2, and data is uploaded and are saved to computer
On host 1；
E, host computer (1) calculates time scale, the literal field that every page children watch attentively according to the eye movement data
Fixation time ratio and picture region fixation time ratio；
Wherein, the time is presented in the whole page fixation time ratio=whole page fixation time/page；
The time is presented in the literal field fixation time ratio=literal field fixation time/page；
The time is presented in the picture region fixation time ratio=picture region fixation time/page；
F, according to children on picture on each point the length of residence time and draw out eye movement thermal map, and according to eye movement heat
Map analysis obtains the children's reading situation.
In this way, host computer 1 calculates children's fixation time ratio according to eye movement data, and according to fixation time ratio
Example generates eye movement thermal map, and obtains the children's reading situation according to the analysis of eye movement thermal map, and give parent and children are corresponding
It is recommended that；And host computer 1 is sent data in plate vice screen 5, and parent can observe the eye movement of children by plate vice screen
Track, to recognize the reading conditions of child.
A kind of children's reading analysis method based on eye movement characteristics of the invention, please refers to Fig. 1-3, the skill described in front
On the basis of the art scheme it may also is that picture area that will have direct relation with the story content for the print hand writing description drawn in this
Domain is defined as key area, and the setting section page has key area, and partial page does not have key area；
Key area fixation time ratio is calculated according to key area eye movement data, and generates eye movement thermal map；
Wherein, this period of key message involved in key area fixation time ratio=key area fixation time/audio.
In this way, the story content described with the print hand writing in picture book is had the picture region directly contacted to determine by we
Justice is key area.Respectively there is a key area the 2nd in this book, in the pictures of page 7,8,9,10,11,12, other pages do not have key area.It is right
In this 7 picture for having key area, we report its eye movement thermal map.Eye movement thermal map be according to children on picture each point
The length of upper residence time and the thermal map drawn, eye movement thermal map should just for this period for being related to key message in audio
The thermal map of page.In addition, we also calculate key area fixation time ratio.
Key area fixation time refers to accumulation of the children to key area in this period for being related to key message in audio
Fixation time.
When key area fixation time ratio refers to key area fixation time divided by this section that is related to key message in audio
Between.
Comprehensive analysis eye movement thermal map notices that duration line chart, index as a result, the case where obtaining children's reading, and are given
Virgin and parent suggests accordingly.
It is above-mentioned that only several specific embodiments in the present invention are illustrated, but can not be as protection model of the invention
Enclose, it is all according to the present invention in design spirit made by equivalent change or modification or equal proportion zoom in or out, should all
Think to fall into protection scope of the present invention.
