Embodiment

Front oneself addresses, and had now some mobile phones to adopt touch slider bar, but the Showing Effectiveness On Screen of this slider bar is not very desirable.In order to improve the display effect of this touch slider bar, at first the slide on touch-screen calculates the parameter of slider bar inertia motion according to the user in the present invention, thereby certain object of which movement with the Motion mapping of slider bar in the real world, and then the mathematic curve of abstract this physical motion rule of searching energy, allow the slider bar that shows on screen close to tie up to according to this mathematic curve represented time one screen position and dynamically change own position on display screen, thereby make the user obtain the visual effect of moving near real world objects.

Based on above-mentioned thinking, at first arrange touch slider bar in a side of touch-screen (be preferably screen below), then set coordinate system on touch-screen, showing object content that screen display is associated with this slider bar such as picture (icon), word, hyperlink etc.For the situation that touch-screen and display screen are integrated, above-mentioned coordinate system and object content are can the up and down overlapping.

Need to prove, the present invention also can expanded application in picture browsing, namely support to slide to the left or to the right with hand picture of browsing a sheet by a sheet arranged in sequence etc.In this case, what slided can be not only slider bar, can be also other object contents such as picture (icon), word, hyperlink.For the convenience on explaining, unification is called slide mass hereinafter.

Slide mass control method for screen display provided by the present invention mainly comprises the work of two aspects, and wherein first aspect is judge and catch the sliding action of user on touch-screen.Only have the user sliding action on touch-screen to follow the tracks of fast and accurately, just can make the slide mass that shows screen display accurately reflect user's operation intention, make the user obtain good operating experience.Second aspect is to calculate the parameter of slide mass inertia motion, seek the mathematic curve of the abstract inertia motion rule of energy, thereby make slide mass simulate the sensation of the object of which movement in real world on display screen, bring the visual effect of moving near real world objects to the user.

Shown in Figure 1, how paper is judged and is caught the sliding action of user on touch-screen.In order to catch the sliding action of user on touch-screen, need to utilize the coordinate system record following parameter relevant to user's sliding action of setting on touch-screen, comprising: the position of user's drop point, for the position of recording user when press in the slide mass zone; The position of user's starting point, the position when leaving after slide mass zone slip one segment distance for recording user; Reaction time, the i.e. time interval between user's drop point and starting point.The reaction time that the user slides must just be looked this user's sliding action in the predetermined time interval be a normal event that can effectively excite the slide mass inertia motion.After the reaction time of having detected user's slide, speed, the direction that just can calculate user's sliding action according to the position of starting point, drop point and reaction time.These parameters will be as the Important Parameters of slide mass inertia motion.

The sliding action of user on screen can be horizontal direction, can be also vertical direction, and both processing modes are identical.We are illustrated as an example of the slip of horizontal direction example.Determine the inertia motion of slide mass, calculative parameter comprises displacement, time, direction etc.The horizontal ordinate of drop point of supposing user's finger contact screen is that x1, time are t1, lifts after sliding a period of time, and the horizontal ordinate of starting point is that x2, time are t2.The speed v of sliding so can be calculated by following formula (1):

v＝(x2-x1)/(t2-t1) (1)

Can be determined displacement and the time of slide mass inertia motion by sliding speed v.Can be determined by x1, x2 as for the direction of sliding motion, when x2＞x1 to the right, when x2＜x1 left.Table 1 is the mapping table of user's sliding action and inertia motion parameter, has wherein provided the reference corresponding relation of sliding speed and seismically-induced sliding movement, time.Design parameter value in table is an example, can adjust according to the needs of application scenarios in actual applications.

Table 1

The once effective slide of user on screen is free restriction, and this time is the reaction time.Only have the reaction time in the effective time scope (according to the feature of human eye, comparatively desirable operating experience is arranged) effective time about 2 seconds, just can excite inertia motion, drag effect and process (drag effect refer to slide mass follow the instant slip of finger) otherwise be used as.

Below, further introduce the implementation procedure that makes slide mass object inertia motion in simulate real world on display screen.Inertia motion in the present invention refers to the motion of object in the motion mimics natural world of slide mass, comprises acceleration, deceleration, the process of slowing down and stopping with the initial speed of motion, acceleration and due to air or various resistance.

The inventor thinks that through research the motion of slide mass is subject to pointing the impact of acting force, in previous stage, and the process that has the change in the short period to accelerate; In the latter half, be subjected to the impact of resistance, the change moderating process in the long period is arranged.This phenomenon can analogy the right and left connecting the motion of the spring oscillator of different damping coefficient.Both all experience in motion process one section in the short period variable accelerated motion and the change retarded motion process within one period long period.This change is accelerated to become in the retarded motion process, and the Changing Pattern of acceleration has identical rule with the variation of the tangent slope of the curve of circle, can be therefore time t in order to horizontal ordinate, and ordinate is that the curve of the circle of displacement s represents this characteristics of motion.

Based on above-mentioned understanding, the present invention adopts Fig. 2 and two section 1/4 circular curve shown in Figure 3 to be illustrated respectively in and accelerates and decelerating phase displacement and the relation of time, and wherein the tangent slope of circular curve represents acceleration.In Fig. 2, tangent slope changes to maximum gradually by zero, has reflected that acceleration is by zero progressive formation to maximum; In Fig. 3, tangent slope changes to zero gradually by maximum, has reflected that acceleration is by the progressive formation that is up to zero.

In concrete processing procedure, at first according to determining direction, time, the distance of slide mass motion to catching of user's sliding action.Then the inertia motion with slide mass will be divided into two stages, become boost phase and become the decelerating phase.Becoming boost phase, the motion of slide mass will be followed time shifting relation curve shown in Figure 2, and speed is increased to maximal value gradually by zero; Becoming the decelerating phase, motion will be followed time shifting relation curve shown in Figure 3, and speed is kept to zero gradually by maximal value.At the volley, slide mass can slide according to the kinetics equation of following definitions with the finger traffic direction, if but arriving the ultimate bound (opening last of picture in one line as N) of all object contents, can finally stop.Due to the cause of inertia, slide mass at the volley may a screen away from keyboard left side or right hand edge and with the inertia segment distance that slides, and the dynamic effect that then imitates spring damping is drawn back in screen and finally stops.

The T.T. of supposing the slide mass inertia motion is T, and total displacement is S, distributes to time of becoming boost phase to be the N of T.T. T/one, and the displacement of generation is the M/of total displacement S, and all the other are distributed to and become the decelerating phase.Relation between N, M need to satisfy this condition of speed that the speed that becomes the boost phase terminal point equals to become the deceleration starting point, can select the best value of one group of movement vision effect pair in actual computation.

Becoming boost phase, the relation of seismically-induced sliding movement s and time t can be provided by following formula (2):

$s=(1-\sqrt{1-{(t\×N/T)}^2})\×S/M,$T ∈ [0, T/N] (2) wherein

Becoming the decelerating phase, the relation of seismically-induced sliding movement s and time t can be provided by following formula (3):

$s=\sqrt{1-{(\mathrm{tN}/(N-1)T-1)}^2}\×(M-1)S/M,$t∈[0，(N-1)T/N] (3)

In the process of practical operation, shown in Figure 1, start timer after calculating the displacement of inertia motion, time and direction parameter.After arriving timer predetermined time interval, calculate current location, the direction of slide mass according to mathematic curve equation (routine formula 1～3 described above), then upgrade screen coordinate, again draw.After the inertia motion of slide mass arrives the schedule time, finish inertia motion.If do not arrive the schedule time, continue waiting timer predetermined time interval arrival.

Distance and direction that the present invention slides on touch-screen by detecting the user, the relevant function of presetting in sustainable execution mobile phone.For example can place the quick startup icon of application program on slide mass, can slide to the left or to the right and browse these icons in order to click fast operation, bring convenience to the user.This slide mass can the perception user finger sliding move and do corresponding inertia motion, the user is sliding left, slide mass is just sliding left; The user is sliding to the right, and slide mass is just sliding to the right; And particularly crucial be its speed of can the perception user sliding with acceleration, user's hand is sliding soon, slide mass is just sliding soon, sliding distance is just far away; Slide mass has experienced one and has accelerated to by change the process of slowing down that becomes in the inertia sliding process, namely slide fast then as progressively stopping the resistance that runs into air or ground in actual scene along with the user points at the beginning, rather than user's hand stops once unclamping at once.Can bring good operating experience to the user like this.

The above has introduced the control method for screen display towards the touch-screen slide mass provided by the present invention.For one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention, it being done all will consist of infringement of patent right of the present invention, will bear corresponding legal liabilities.
