Embodiment
Below in conjunction with drawings and Examples the present invention will be further explained explanation.
Fig. 1 is the structured flowchart of mobile terminal first embodiment of the present invention, as shown in Figure 1, in the present embodiment, mobile terminal of the present invention comprises touch-screen 110 and processor 120, touch-screen 110 comprises touch sensor 111 and the display unit 112 for displaying contents, and processor 120 comprises the first processing unit 121.
In the present embodiment, mobile terminal of the present invention has multi-touch function.Traditional touch-screen once can only judge a touch point, if there is plural point to be touched simultaneously, just correct response can not be made, react chaotic in other words, multi-touch function can realize being the work of two aspects by whole Task-decomposing, one is gather multi-point signal simultaneously, and the meaning of two Shi Duimei road signals judges, namely so-called gesture identification.
In the present embodiment, first user uses the first finger touch touch-screen 110, and now the first processing unit 121 receives the touch signal of the first finger by touch sensor 111 and records this signal position A corresponding on touch-screen 110.Then, user uses second finger touch touch-screen 110, first processing unit 121 receive the touch signal of second finger by touch sensor 111 and record this signal position B corresponding on touch-screen 110.
First processing unit 121 judges that first and second fingers of user do not input other actuating signal again, the second finger of user now contacts with touch-screen 110 by means of only the mode touched, the first processing unit 121 calculate the touch signal of the first finger first received position A corresponding on touch-screen 110 to after the displacement of touch signal position B of correspondence on touch-screen 110 of second finger that receives.
First processing unit 121 is according to the size of described displacement | and AB| determines the first rolling rate V
1, the size of the first rolling rate and described displacement is directly proportional: V
1=K*|AB|; Wherein K is scale-up factor, is set in advance in the first processing unit 121 according to practical application.Determine the first rolling rate V
1after, the first processing unit 121 controls display unit 112 with the first rolling rate V
1roll display content on the direction of described displacement.As long as first finger of user and second finger continue touching touch-screen 110, and the position of touching does not change, the first processing unit 121 will control display unit 112 with the first rolling rate V
1roll display content always on the direction of described displacement, until the first processing unit 121 receives by touch sensor 111 signal that signal that first finger terminates to touch and/or second finger terminate to touch, then or displaying contents be rolled to edge.
That is, when during user first and second points leaves touch-screen 110, roll and will stop.
Fig. 2 is the fundamental diagram of mobile terminal first embodiment of the present invention, as shown in Figure 2, when mobile terminal is started working in display unit 112 displaying contents; First processing unit 121 judges whether successively have two finger touch to screen, otherwise continues normal displaying contents, is, judges the mode whether second finger of rear contact passes through to touch and screen contact; If by touch manner to contact, first processing unit 121 according to first finger and second finger displacement on the touchscreen (be the scale-up factor being preset in the first processing unit 121) according to a certain percentage calculate rolling speed (speed is vector, those skilled in the art can be corresponding with description before), the first processing unit 121 controls display unit 121 with described speed scroll displaying contents; First processing unit 121 judge in the first and second fingers at least one whether terminate to touch, control that display unit 121 stops roll display content, flow process terminates, otherwise perform judge after the second finger of contact whether by the step of the mode that touches and screen contact.
Mobile terminal of the present invention also supports that existing single finger sliding changes direction and the speed of roll display content.Namely according to user's finger direction of slip and speed of speed determination roll display content on touch-screen 110, reduce speed now after finger frames out, reduce to 0 and just stop rolling.
Fig. 3 is the structured flowchart of mobile terminal second embodiment of the present invention, and as shown in Figure 3, in the present embodiment, processor 120 also comprises the second processing unit 122.
In the present embodiment, second processing unit 122 receives the first finger from touching slip signals and/or second finger from touching slip signals by touch sensor 111, calculates the distance between position that the first finger touches or slide on described touch-screen 110 and the position that second finger touches or slides on described touch-screen 110.The first finger that described first finger refers to user from the signal touching slip has slided into another touch point A ' from original touch point A, and second finger has slided into another touch point B ' from the second finger touching slip signals and refer to user from original touch point B.Above-mentionedly touch in the process of slip, hand-held maintenance is to the contact of touch-screen 110.Because the distance calculated is scalar, because the position of the first and second fingers all can change.Such as, second processing unit 122 receives the first finger from touch point A to having slided into new touch point A by touch sensor 111 " signal at place; judge to need to change the speed of rolling; it records new touch point A ", calculate new touch point A " and the former touch point B of second finger between distance.This process can be understood as, second processing unit 122 is waiting for the information received from touch sensor 111 information occurred from touching slip always, therefore, the second processing unit 122 also can determine the touch point B that the second finger touch information that now do not change is corresponding.
Second processing unit 122 determines the second rolling rate V according to the distance S calculated
2, adjust display unit 112 on the direction of displacement with described second rolling rate V
2roll display content.Second processing unit 122 only changes the speed of rolling and does not change the direction of rolling.Second rolling rate V
2be directly proportional with the size of distance S: V
2=K*S; Wherein K is scale-up factor, is set in advance in the second processing unit 121 according to practical application.Visible, in the present embodiment, distance S and the second rolling rate V
2scale-up factor and the size of described displacement | AB| and the first rolling rate V
1scale-up factor identical.In other embodiments of the invention, above-mentioned two scale-up factors can be different.
In the present embodiment, all the other situations are identical with the first embodiment of mobile terminal of the present invention, do not repeat them here.
In the third embodiment of the present invention, processor 120 also comprises scale-up factor adjustment unit, for adjusting the scale-up factor preset in the first processing unit 121 and the second processing unit 122.In the present embodiment, all the other situations are identical with the second embodiment of mobile terminal of the present invention, do not repeat them here.
