And y sensors are arranged in the vertical direction, and mainly feed back the change of the horizontal direction of the finger, wherein y is more than 2.
The finger change is tracked by the network formed by the arrays in the two directions.
2) One part of the sensors are placed according to an angle α, and the other part of the sensors are placed according to an angle β, wherein the angle is more than 0 and less than or equal to α - β and less than or equal to 90.
Therefore, each sensor can simultaneously feed back the change of the finger in the horizontal direction and the vertical direction, and the change of the finger is tracked through the network formed by the array.

Preferably, the preset weight is set according to a rule that the closer to the sensor of the missing track, the greater the corresponding preset weight.
Therefore, whether the two tracks are two tracks of the same track or not can be determined, and the track information of the missing track between the two tracks can also be determined. Therefore, the track information of the missing track is identified and supplemented by carrying out instant track analysis processing on the sensed information, so that the identification accuracy of continuous operation of the continuous track is improved.
In this embodiment, the specific fitting method includes:
a. n sensors of the first trajectory are selected. Denoted as Q1Q2 … … Qn, respectively, the greater the ordinal number of Q, the further away from the tip coordinate. The data points Q1Q2 … … Qn are respectively given corresponding preset weights Q1Q2 … … Qn (Q1> Q2 … … > Qn). Here, the weights may be taken in a variety of ways, including but not limited to a) q1 ═ n; q2 ═ n-1; … … qn is 1; B) q1 ═ 1; q2 ═ n-1)/n; … … q2 is 1/n, etc.
b. In the same method, selecting n sensors of the second track, and respectively recording the n sensors as H1H2 … … Hn; the same method is used to assign a weight coefficient h1h2 … … hn (h1> h2 … … > hn).
c. The data Q1Q2 … … Qn and H1H2 … … Hn are weighted by weighting coefficients Q1Q2 … … Qn and H1H2 … … Hn, respectively.
d. Performing curve fitting by using the weighted data; there are many curve fitting methods, and the most common methods are least square method, lagrange interpolation method, newton interpolation method, and the like. And calculating the position information of the sensor marked as the missing track through the fitted curve.
Here, the least square method (also called the least squares method) is a mathematical optimization technique. It finds the best functional match of the data by minimizing the sum of the squares of the errors. Unknown data can be easily obtained by the least square method, and the sum of squares of errors between these obtained data and actual data is minimized. The least squares method can also be used for curve fitting;
in numerical analysis, the lagrange interpolation method is a polynomial interpolation method named by the mathematician joseph lewis lagrange of eighteen centuries of france. Many practical problems are represented by functions, and many functions can be understood only by experiments and observation. If a certain physical quantity in practice is observed, and corresponding observed values are obtained at a plurality of different places, the Lagrangian interpolation method can find a polynomial, and the observed values are just obtained at each observed point. Such a polynomial is called lagrange (interpolation) polynomial. Mathematically, the Lagrangian interpolation method can give a polynomial function that passes exactly through several known points on a two-dimensional plane.
Newton interpolation uses the function f (x) at points in a certain interval to make a suitable specific function, and takes the known values at these points, and uses the values of this specific function as approximate values of the function f (x) at other points in the interval.
