The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of utility model is not limited thereto.
As illustrated in fig. 1 and 2, read chair based on the automatic page turning that sight line is followed the trail of, comprise seat 1 and be located at the control device on the seat 1 that control device 2 is located at the bottom of seat 1.Seat 1 is provided with backrest 10, and curved boom 3 is located on the backrest 10.One end of curved boom 3 is located on the seat 1, and its other end is connected with montant 4.Montant 4 is provided with bookshelf 5.
As shown in Figure 3, bookshelf 5 tops are provided with camera 6, and the both sides of bookshelf 6 are respectively equipped with the left bar 7 and right bar 8 of pivotable, but the middle part of bookshelf 6 is provided with the ruler 9 of pivotable and translation.The signal input part of control device is connected with camera 6, and its signal output part is connected with left and right sides bar 7,8 respectively.
When reading, left and right sides bar 7,8 all is pressed on the page.In the time of need turning over book left, right bar 8 is communicated with electrostatic circuit, and upwards the turning handle page sucks up simultaneously, and ruler 9 begins to forward in the gap of digging page then, and right bar 8 breaks off electrostatic circuit; When ruler 9 forwarded book middle to, right bar 8 rotated, up to being pressed on the page; When ruler turned over book middle, left bar 7 began upwards to rotate; When page was translated into the left side, left bar 7 down rotated, up to being pressed on the page.Turn over the flow process of book and above-mentioned reversed in order to the right.
As shown in Figure 4, the control device of chair is read in a kind of automatic page turning of following the trail of based on sight line, comprises image capture module 21, eye movement detection module 22, signal processing module 23, A/D modular converter 24 and pulse control module 25; Above-mentioned module connects successively.
As shown in Figure 7, said eye movement detection module 22 comprises image difference value, geometric transformation, compensates and repair sun, extracts eyeball moving track, and extract trajectory and calculate the mid point of sight line, and the capture card 221 that compares with initial position.Said signal processing module 23 comprises signal amplification circuit and the filter circuit that receives amplifying signal.。Like this design effectively filtering interference signals eliminate noise signal simultaneously.
As shown in Figure 8, A/D modular converter 24 comprises single chip machine controlling circuit 241, jtag port 242, reference voltage circuit 243, input voltage circuit 244 and power circuit 245.Power circuit 245 is connected with input voltage circuit 244, single chip machine controlling circuit 241 respectively; Jtag port 242, reference voltage circuit 243 are connected to single chip machine controlling circuit 241 with input voltage circuit 244.
As shown in Figure 9, pulse control module 25 comprises power switch pipe VT1-VT4, diode VD1-VD4 and motor.Power switch pipe VT1, VT3 emitter stage are electrically connected with motor, and the colelctor electrode of power switch pipe VT1, VT3 is connected with the cathodic electricity of diode VD1, VD3 respectively; The anode of diode VD1, VD3 is electrically connected with motor.The colelctor electrode of power switch pipe VT2, VT4 is electrically connected with motor, and the emitter stage of power switch pipe VT2, VT4 is electrically connected with the anode of diode VD2, VD4 respectively, and the negative electrode of diode VD2, VD4 is electrically connected with motor.Clockwise or the counterclockwise both direction of pulse control module 25 control motors rotates.VT1 and VT2, VT3 and VT4 do not allow conducting simultaneously.When motor clockwise rotates, make Ug3 permanent for cloudy, the Ug4 perseverance is a sun, then VT3 ends and the VT4 normal open.When motor rotates counterclockwise, make the Ug3 perseverance permanent in cloudy, then VT3 normal open and VT4 ends for sun Ug4.
As illustrated in Figures 5 and 6, human vision system can be regarded as by ingenious and accurate optics of series of abnormal and electrical devices to be formed.For example, in oculomotor process, can produce measurable change in location.When people's eyeball moved, the mid point M of two eyeball pupil track line H can produce offset, compared the control signal that can moved to left or move to right through the M point position that sets when initial.Utilize this principle, just can utilize the motion of eyeball and computer system to carry out interactive operation, thereby realize that the reader's turns over the book function.And in the reading process of reality; People's eyeball possibly have trickle mobile variation; And being the reader, this variation do not want to turn over the wish of book; Therefore in the design, be provided with an error range N, the mid point offset distance that has only eyeball pupil track line just turns over book greater than N/2 the time.
As follows, be somebody's turn to do the control method of the automatic page turning reading chair of following the trail of based on sight line, comprise the steps:
1) gathers user's sight line movement locus image;
2) user's sight line movement locus image is discerned, obtained the eye movement data signal;
