For example, see also following table one, the first relative coordinate reference point and the second relative coordinate reference point in the touch control terminal acquisition the five fingers between thumb and forefinger are respectively Δ x1 and Δ y1, the first relative coordinate reference point and the second relative coordinate reference point of thumb and middle interphalangeal are respectively Δ x2 and Δ y2, the first relative coordinate reference point and the second relative coordinate reference point between thumb and the third finger are respectively Δ x3 and Δ y3, the first relative coordinate reference point and the second relative coordinate reference point between thumb and little finger refer to are respectively Δ x4 and Δ y4, the first relative coordinate reference point and the second relative coordinate reference point of forefinger and middle interphalangeal are respectively Δ x5 and Δ y5, the first relative coordinate reference point and the second relative coordinate reference point between forefinger and the third finger are respectively Δ x6 and Δ y6, the first relative coordinate reference point and the second relative coordinate reference point between forefinger and little finger are respectively Δ x7 and Δ y7, the first relative coordinate reference point and the second relative coordinate reference point between middle finger and the third finger are respectively Δ x8 and Δ y8, the first relative coordinate reference point and the second relative coordinate reference point between middle finger and little finger are respectively Δ x9 and Δ y9, and the first relative coordinate reference point and the second relative coordinate reference point between the third finger and little finger are respectively Δ x10 and Δ y10.The five fingers relative position is kept at this locality with reference to information following table one form.
Table one: the five fingers relative position is with reference to information
| Thumb+forefinger | （Δx1，Δy1） | Forefinger+third finger | （Δx6，Δy6） |
| Thumb+middle finger | （Δx2，Δy2） | Forefinger+little finger | （Δx7，Δy7） |
| Thumb+third finger | （Δx3，Δy3） | Middle finger+third finger | （Δx8，Δy8） |
| Thumb+little finger | （Δx4，Δy4） | Middle finger+little finger | （Δx9，Δy9） |
| Forefinger+middle finger | （Δx5，Δy5） | The third finger+little finger | （Δx10，Δy10） |
Step S203: each finger center that touch control terminal obtains at least two fingers in the touch screen induction region respectively is at first coordinate figure of described touch screen X-direction with at second coordinate figure of Y direction.
When at least two fingers of user are touched touch screen with certain gestures, touch control terminal as the finger center, and obtains each finger center respectively in first coordinate figure of X-direction and second coordinate figure on the Y direction positional information as this finger with each finger geometric center in touching zone on touch screen.The five fingers certain gestures basically identical when wherein, described at least two present particular hand states of finger and user obtain the five fingers relative position with reference to information.
Step S204: touch control terminal is defined as described two one of them fingers of finger with reference to finger at least, calculate respectively other finger with reference between finger the difference of X-direction with as the first relative coordinate value and in the difference of Y direction with as the second relative coordinate value, thereby the relative position information between at least two fingers of acquisition.

Step S205: touch control terminal with the relative position information between described at least two fingers respectively and the five fingers relative position compare with reference to information with reference to the relative position between per two fingers in the information, obtain corresponding described relative position with reference to the combination of the finger of information with reference to information.
After touch control terminal obtains relative position information between at least two fingers in the touch screen induction region, with the relative position information between described at least two fingers respectively and the five fingers relative position compare with reference to information with reference to the relative position between per two fingers in the information.
For guaranteeing that touch control terminal can identify the finger combination that the user done, at least two fingers of user at every turn with the certain gestures touching touch screen of the five fingers relative position with reference to the information basically identical.Because each certain gestures may not be identical, relative position information between causing pointing and the five fingers relative position difference occurs with reference to information, so touch control terminal is preset with the relative position information that allows finger and with reference to the first threshold that has error between information and second threshold value.In the present embodiment, described first, second default threshold value is touch control terminal systemic presupposition value, but in other embodiments, described first, second default threshold value also can be the user by the value that corresponding inputting interface sets in advance, and does not limit at this.
Touch control terminal respectively with in described at least two fingers with reference to the first relative coordinate value between finger and other fingers and the second relative coordinate value and the five fingers relative position with reference to the first relative coordinate reference point between per two fingers and second relative coordinate reference point comparison in the information.If the five fingers relative position with reference to the difference of the first relative coordinate reference point between two fingers in the information and the described first relative coordinate value between pointing with reference to finger and other less than presetting first threshold, and the second relative coordinate value between the second relative coordinate reference point between described two fingers and described reference finger and described other fingers is less than the second default threshold value, determine that then the described finger of forming with reference to finger and described other fingers is combined as between described two fingers relative position with reference to the corresponding finger combination of information, obtain relative position between corresponding described two fingers and make up with reference to information with reference to the finger of information.
Step S206: touch control terminal with reference to information, is determined the finger combination that described at least two fingers are formed according to the described finger combination of obtaining.
Touch control terminal makes up with reference to information according to the finger that obtains, determine the finger type of described at least two fingers, for example, determine that the gesture-type of described at least two fingers is respectively thumb, forefinger and middle finger, and then determine the finger combination that described at least two fingers are formed.
Step S207: touch control terminal finds out the corresponding operational order of forming with described at least two fingers of finger combination, and carries out described operational order from default finger compound command set.
Touch control terminal from default finger compound command set, finds out and described two operational orders that the finger combination is corresponding, and carries out described operational order after determining finger combination that described at least two fingers form at least.
In conjunction with Fig. 3 and the explanation for example of last table one, when thumb, forefinger and the middle finger that touch control terminal detects the user touched touch screen simultaneously, point as reference with thumb, calculate the first relative coordinate value Δ x1, the second relative coordinate value Δ y1 between thumb and forefinger, and the first relative coordinate value Δ x2 of thumb and middle interphalangeal, the second relative coordinate value Δ y2, as the relative position information of at least two fingers.Touch control terminal is respectively with (Δ x1, Δ y1), (Δ x2, Δ y2) the five fingers relative position with last table one compares with reference to information, to obtain and (Δ x1, Δ y1) combination of the finger of coupling is " thumb+forefinger " with reference to information, the finger combination of mating with (Δ x2, Δ y2) is " thumb+middle finger " with reference to information.With reference to information, touch control terminal determines that the finger type of touching touch screen has thumb, forefinger and middle finger according to the finger combination that obtains, and then determines that the finger of touching touch screen is combined as " thumb+forefinger+middle finger ".In default finger compound command set, definition detects the first finger combination that " thumb+forefinger+middle finger " form and then carries out and be moved to the left operational order, detect second finger combination that " forefinger+middle finger+third finger " form and then carry out and determine operational order, detect the 3rd finger combination that " middle finger+third finger+little finger " form and then carry out the operational order that moves right.According to above-mentioned finger compound command set, touch control terminal finds out the be moved to the left operational order corresponding with " thumb+forefinger+middle finger ", and execution is moved to the left the touch screen interface content.
