The infrared rays emitted by the image sensors m and 12G are illuminated on the surface of the screen 15 。. Taking FIG. 1 as an example, θο and Θ 9 are the angles at which the image sensor and the 11 〇 are detected by the user, and Θ, 0Ι%Θ, 9 are detected by the image sensor 120. The angle at which the person touched the position. The processing unit 130 receives the angles (Θ and θ') returned by the image sensors 11〇 and 12〇 to calculate the touch position of the user touch position on the screen, and the shape touches the silk history. The location (4) is stored in the temporary memory Μ0. The temporary memory 140 is used to temporarily store the historical touch position calculated by the processing unit 13A. In the first item, Ρ〇~ρ8 is a plurality of historical touch positions that have been stored in the optical touch camp. For example, the historical touch positions ρ 〇 Ρ 8 are stored in the temporary memory 140. In this embodiment, it is assumed that the touching object (e.g., hand, pen, etc.) is moving at a constant speed or approximately constant speed. Therefore, in the first embodiment, the lower-touch position can be estimated based on the money touch position Ρ{). In more detail, in the first embodiment, the estimated interval A can be generated according to the historical touch position Ρ〇~ρ8, and the side down-touch position is in the shape of the estimated area. To decide whether to connect the next touch position to the historical touch position. For example, the image sensor 11 〇 201209647 and 12 撷 can capture 12 frames of images in one second. In this embodiment, the 'per image screen' image sensors 110 and 120 transmit back a human sensing angle to the processing unit.

'If yes, the connection 1 does not repeat the above steps until the =4 images are not detected in the plane - the touch position is in the fourth pre-A, then even The line will therefore be interrupted. On the other hand, if it is, in-plane, the processing unit 13 is used. If it is determined that the detected down-touch position is in the estimated time A, the target step σσ - the last touch position of the next touch position history hit by the beibei processing 70 130 Ρ8 is connected, and the next ^ position is stored as the historical touch position Ρ9 and stored in the temporary memory _. The detected position is below the touch interval 不是 Γ Γ & & & & & Touch the stone position and the last touch position in the historical touch position 8" spring and use the detected lower-touch position as a new one. In the picture, for example, 'every four images, image sense. The detector m senses the face to obtain the Θ and Θ, and passes it to the processing unit 130 to calculate the touch position. See how the children's month generates an estimated interval based on the historical touch position. In the present example, if the number of stored historical touch positions is sufficient, 'here, the stored historical touch position includes at least two. In the case of a historical touchstone position, in an embodiment, as shown in the figure, the figure contains nine 201209647 * wuHjurn historical touch positions, the center point c of the estimated interval A is expressed as c=p8(x'y)+vm , ρ8 (χ, γ) represents the historical touch position p8 coordinates. t represents the sensing interval of image sensing of 11 〇, 12 ( (that is, the time difference between the image sensor detecting the touch position PS to Pg, in the above example, 't=1 image frame (0 · 0083 seconds) >.v represents the speed between the average speed of the sum & or Pd P8. That is to say, in this case, the center point of the estimated interval A is the estimated center point. ◦, and its radius is R. Although the prediction interval is a circle, the invention is not limited to this. V9 represents the center point c(Cg) of the estimation interval a to the touch ϋί P8 The vector between the vector, the direction of the vector V9 (also called the prediction interval A. The direction factor of the reading point c (di_Qn) is the vector Vg obtained by the vector, the quantity V, where the vector V8 represents the historical touch. 3 sets /8 and the vector formed between the origin coordinates of the screen 150, and forms a vn between the touch position P7 and the origin coordinates of the screen (10). In the vector two, the heart point vector V has the same direction. ), and the center point C ζ ρ of the position two inward is estimated, although the above direction factor is ρ7 : between: distance. : Note point is obtained, the nearest 2' (four) is higher than the accuracy of 8. s can also be taken by any 2 processing unit 130 may take the same time, the distance can represent the distance between 9 speed 7 = (due to equal or Approximate, it is determined whether or not the distance between the t^']P7 is k or not, and whether the next touch position 201209647 P9 is located in the estimated interval A. ▲ In this embodiment, if the number of historical touch positions is If there is not enough, it is assumed that the stored historical touch position includes only one historical touch position P. Then, the center point c of the P1 estimation interval is the only historical touch position PD. The range is the center point c disk zhong r determines 'if ―p】 falls within the estimated range, then the position information of Pg and Ρι connected and ς Ρ! is stored in the temporary memory 14 。. Second embodiment: non The present invention is referred to the second embodiment of the present invention. Referring to FIG. 2, a schematic diagram of a method of connecting a touch trajectory of a light-drying touch screen according to a second embodiment of the present invention is provided. In more detail, in the second embodiment, The touch object is moved at a non-equal speed, so the prediction interval is generated. Different from the first one, of course, in the four image frames, if the processing unit 13 determines/has a debt-measured down-touch position in the interval wipe, the connection will be interrupted. In the embodiment, if the processing unit single gamma determination _ to the lower-touch position is located in the estimation interval A in the four image frames, the processing unit 13Q will touch the touch position with the history. The last touch position P8 in the position is connected, and the lower-touch position is stored as the historical touch position 储存 in the temporary memory 140. If the detected next touch position is not located in the estimated interval In the case of A, the last touch position & disconnection of the lower i-touch position and the historical touch position is a new starting point by the detected lower-touch position #. A. Will now. According to the historical meaning, the prediction interval is generated in the first example. If the number of historical touch positions is enough 201209647, it is assumed that the stored historical touch position includes at least three historical contacts. Position, in the present embodiment, 'If the second map contains nine historical touch positions, the center point 预估 of the estimated interval A can represent C9=P8(X,Y)+V8*t+0.5*a*t2, Where 'Vs represents the speed at which the touch object touches the position Ps, and t represents, for example, 1 image frame (〇〇〇83 seconds), a represents the acceleration of the touch object, and Ve*t is also called the speed factor. .5*a*t2 is also known as the acceleration factor. After assuming that the touch object moves at an equal acceleration, then v8=[(P8(X,Y)-P7(X,Y)]/t , and • a=0VV7)/t,p8(x,Y)-P7 (x, Y)H(P7(x,Y)-P6(X,Y)]Vt2, V7 represents the speed at which the touch object passes the touch position P?

Please refer to the 帛2 diagram again. V9 represents the vector of & to the touch position 8^. The direction of this vector V9 is the vector V8 minus the vector v7: the inward Vc ( That is to say, the center point c is located on the delay of the vector ν〇), and its size (called the position factor) is expressed as: . Ρ7(Χ'丫)]+〇·5*{[(ρ8(χ> ;γ)-ρ7(χ,Υ)Η(Ρ7(Χ,Υ)-Ρ6(χ,γ)]} can be implemented in two. If there are at least two historical touch positions, calculate the comparison factor, not limited to 2 points in the past, but according to the last 2 points, at least 3 historical touch points need to be calculated at 3 points. The calculation is more accurate. Square/limited to 3 points' but according to the recent position factor, the decision is made. Estimate the direction of the interval ,, touch the object two; touch the distance between the positions P8. When the big turn is not equal to move all the time, the touch object may be in the E, but in the second 201209647 In the embodiment, the direction factor and the position factor are imported to correctly estimate the possibility of the next touch position. The position of the drop point. In detail, the import direction factor can more accurately predict the possible moving direction of the touch object. The lead-in position factor can more accurately estimate the center of the estimated range with the possible acceleration behavior of the touch object. The distance between point c and the previous historical touch position. That is, if the acceleration of the touching object is larger, the position factor will be larger, so that the center point c of the estimated interval is away from the historical touch position. The farther the last touch position is, the farther it will be explained. In the second embodiment, if the number of stored historical touch positions is not enough, how to generate the estimated interval A. The following will explain: (1) The stored historical touch position includes two historical touch positions and (2) the stored historical touch position includes only one historical touch position. (1) The historical touch position includes two historical touch positions if stored. The historical touch position includes only two historical touch positions Ρ〇~P1, and the direction factor of the center point of the estimated interval A is (P1(X,Y)-P〇(X'Y))' Position factor ((卩状丫)-卩状丫)). (2) The historical touch position only includes—a historical touch position. If the historical touch position includes—the historical touch position ρ〇, the estimated range is The center point (3 is as follows: ° C = P〇(X,Y) Therefore, in this case, the direct cerebral palsy position can directly directly store the historical touch P〇 stored as the center of the estimated interval A Point c. In addition, the situation of 'touching object moving at constant speed can be regarded as touching object non-equal 201209647

Le) T /, 疋 ^ Γ outside ' in the second embodiment of the present invention, The estimated interval is adjusted according to the position factor. In detail, if the position factor is higher than the upper limit threshold, the estimated interval A is increased (for example, if the radius R is increased, the acceleration of the touch object is very high, in order to be more accurate and predictable - under - Touching the possible drop point of the stone sub-position, so the estimated interval a is increased. If the opposite position factor is lower than the lower limit service value, then the estimated area is reduced, such as 'the radius R becomes smaller.' The addition of the object is very low (and may even be decelerating). In this case, the estimated interval A is reduced to save the ability to move and/or save power. Fig. 4 shows the center point 预估 of the historical touch position p and the estimated interval A estimated according to the second embodiment of the present invention. As can be seen from FIG. 4, the coefficient of the center point c of the estimated interval a estimated according to the second embodiment of the present invention can be regarded as being within the tolerance range, so the touch of the second embodiment of the present invention The execution connection method has high accuracy. In addition, although the above embodiment is described by taking an optical touch screen that cannot continuously generate touch position information in a short time, the present invention is applied to a non-optical touch camp screen, for example, Short time ^ A capacitive/resistive touch screen that produces continuous touch position information is also within the spirit of the present invention. In the above, the present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the present invention.
