At present, interactions between intelligent mobile terminal applications become more and more diversified, and users start to desire various sliding interactions. In general, however, such a method for achieving a sliding operation by using the system controls can only address simple sliding requirements and cannot satisfy various sliding interactions due to the fixed sliding time and non-customized sliding actions, thereby reducing the degree of the user experience.

Block S101: obtaining an overall sliding distance and overall sliding time from a sliding start location to a sliding termination location.
Block S102: drawing, at the sliding start location, a sliding trace in a current image frame and recording a current time point when the drawing of the current image frame is completed.
Block S103: obtaining drawing time from a drawing start time point to the current time point when the drawing of the current image frame is completed, and determining whether the drawing time is greater than or equal to the overall sliding time; on the condition that the drawing time is less than the overall sliding time, Block S104 is to be performed, and on the condition that the drawing time is greater than or equal to the overall sliding time, Block S105 is to be performed.
Block S104: drawing, at the sliding termination location, a sliding trace in the last image frame, on the condition that the drawing time is less than the overall sliding time, obtaining a current sliding distance according to the drawing time, the overall sliding time and the overall sliding distance, resetting the sliding start location as the sum of the sliding start location and the current sliding distance, and returning to Block S102.
Block S105: drawing, at the sliding termination location, a sliding trace in the last image frame.
Preferably, the process of obtaining the current sliding distance according to the drawing time, the overall sliding time and the overall sliding distance includes generating an inertia proportion according to the drawing time and the overall sliding time, and multiplying the inertia proportion by the overall sliding distance to obtain the current sliding distance.
Preferably, the process of generating an inertia proportion according to the drawing time and the overall sliding time includes dividing the drawing time by the overall sliding time to obtain a drawing proportion and deriving the inertia proportion from the drawing proportion according to the formula: the inertia proportion=(the drawing proportion−1)2*(2*the drawing proportion−1)+1.
Preferably, the process of obtaining an overall sliding distance and overall sliding time from a sliding start location to a sliding termination location includes obtaining an overall sliding distance and the overall sliding time of a user which slides from a sliding start location to a sliding termination location.
Preferably, the process of obtaining an overall sliding distance and the overall sliding time from a sliding start location to a sliding termination location includes obtaining an overall sliding distance and overall sliding time preset by the system from a sliding start location to a sliding termination location.
In this embodiment, firstly, obtain the overall sliding distance and the overall sliding time, draw a sliding trace in the current image frame at the sliding start location and record the current time point when the drawing of the current image frame is completed; on the condition that the drawing time is less than the overall sliding time, obtain a current sliding distance, reset the sliding start location as the sum of the sliding start location and the current sliding distance, repeatedly perform the drawing of subsequent image frames until the drawing time is greater than or equal to the overall sliding time, and draw a sliding trace in the last image frame at the sliding termination location. Compared with the method for achieving a sliding operation by using the system controls, the drawing time and sliding action in this embodiment can be customized and then be obtained by the mobile terminal, thus various sliding interactions can be implemented, thereby improving the degree of the user experience.
Referring to
The method for drawing a sliding trace includes the followings:
Block S201: a mobile terminal obtains an overall sliding distance and overall sliding time from a sliding start location to a sliding termination location.
In this block, when the user starts to slide on a touch screen of the mobile terminal, the mobile terminal may obtain an overall sliding distance and overall sliding time when the user slides from a sliding start location to a sliding termination location. Alternatively, when the system of the mobile terminal needs to play an animation, the mobile terminal may obtain the overall sliding distance and the overall sliding time preset by the system from a sliding start location to a sliding termination location.
In this embodiment, the sliding action of the user performed on the touch screen of the mobile terminal may be customized, and it is not limited to this embodiment. The mobile terminal may use the sliding distance and the sliding time as parameters to initialize a sliding distance calculator, and then obtain the overall sliding distance and the overall sliding time from a sliding start location to a sliding termination location via the sliding distance calculator. The sliding distance calculator may be implemented by logical programs.
Block S202: the mobile terminal draws at the sliding start location a sliding trace in a current image frame and records the current time point when the drawing of the current image frame is completed.
In this block, when the user starts to slide or when the system plays an animation, the mobile terminal draws images frame by frame. Specifically, when the user starts to slide or when the system plays an animation, the sliding distance calculator of the mobile terminal is activated, and meanwhile, the sliding distance calculator sends a start drawing massage to a drawing thread of the user interface of the mobile terminal, and the drawing thread of the user interface starts to draw images frame by frame upon receiving the start drawing massage.
For example, the mobile terminal starts to draw a sliding trace in a first image frame at the sliding start location, and the drawing start time point is denoted as starttime (such as 14:12:39:289 on Feb. 20, 2012), and when the drawing for the first image frame is completed, record the current time point which is denoted as currenttime when the first image frame is completed (such as 14:12:39:389 on Feb. 20, 2012).
It is noted that, the drawing start time point of the first image frame may be the same as the sliding start time point, or the difference between the drawing start time point of the first image frame and the sliding start time point is made as small as possible, as such, the sliding trace can be drawn as soon as the sliding operation starts, thereby reducing a delay of drawing the sliding trace. For example, when the user starts to slide on the touch screen of the mobile terminal, the mobile terminal may perform an operation of drawing the sliding trace in the current image frame at the sliding start location, and thus the drawing start time point of the first image frame may be consistent with the sliding start time point.
Block S203: the mobile terminal obtains drawing time from the drawing start time point to the current time point when the drawing of the current image frame is completed, and determines whether the drawing time is greater than or equal to the overall sliding time; on the condition that the drawing time is less than the overall sliding time, Block S204 is to be performed, and on the condition that the drawing time is greater than or equal to the overall sliding time, Block S205 is to be performed.
In this block, when the mobile terminal completes the drawing for the first image frame, the mobile terminal invokes an interface function of the sliding distance calculator to obtain the current sliding distance. The sliding distance calculator obtains the drawing time (i.e., the drawing time from the starttime to the currenttime, or referred to as the sliding time from the starttime to the currenttime) according to the difference between the drawing start time point starttime and the current time point currenttime when the first image frame is completed. Then, the mobile terminal determines whether the drawing time is greater than or equal to the overall sliding time, and performs the corresponding process according to the determination result.
Block S204: the mobile terminal obtains a current sliding distance according to the drawing time, the overall sliding time and the overall sliding distance, resets the sliding start location as the sum of the sliding start location and the current sliding distance, and returns to Block S202.
On the condition that the drawing time is less than the overall sliding time, the sliding distance calculator of the mobile terminal obtains the current sliding distance according to the drawing time, the overall sliding time and the overall sliding distance.
Specifically, the sliding distance calculator of the mobile terminal may derive the current sliding distance according to formulas (1) and (2):
the drawing proportion=the drawing time/the overall sliding time (1)
the current sliding distance=the overall sliding time*the drawing proportion (2)
Since both of the process for drawing images and the process for calculating the current sliding distance are time consuming, preferably, in order to make the sliding operation exhibit a better fluency and real experience, an inertia formula is additionally used in the process for calculating the current sliding distance in this embodiment.
Specifically, the mobile terminal generates an inertia proportion according to the drawing time and the overall sliding time; and the mobile terminal multiplies the inertia proportion by the overall sliding distance to obtain the current sliding distance.
The sliding distance calculator of the mobile terminal generates the inertia proportion according to the drawing time and the overall sliding time by using formulas (1) and (3), and the sliding distance calculator generates the current sliding distance according to the overall sliding time and the inertia proportion by using formula (4). The formulas are specifically as follows:
the drawing proportion=the drawing time/the overall sliding time (1)
the inertia proportion=(the drawing proportion−1)2*(2*the drawing proportion-1)+1 (3)
the current sliding distance=the overall sliding time*the inertia proportion (4)
After obtaining the current sliding distance, the mobile terminal resets the sliding start location as the sum of the sliding start location and the current sliding distance, and returns to Block S202 to repeatedly perform subsequent processes to make drawings for other image frames that follow the first image frame. For example, provided that the sliding start location is denoted as startX and the current sliding distance is 40 pixels, the new sliding start location may be reset as (startX+40 pixels), and the mobile terminal returns to Block S202 to draw a sliding trace for the second image frame. When the mobile terminal draws the sliding trace for the second image frame, the sliding trace for the first image frame is erased first and then the sliding trace for the second image frame is drawn. The drawing processes for other image frames are similar to that of the second image frame, that is, before the sliding trace for the current image frame is drawn, the sliding trace for the previous image frame is erased. Repeat this process to sequentially draw the sliding traces for the subsequent image frames until the drawing time is greater than or equal to the overall sliding time.
In this embodiment, the relationship between the sliding distance and the drawing time is as shown in
Block S205: the mobile terminal draws a sliding trace in the last image frame at the sliding termination location.
When the drawing time is greater than or equal to the overall sliding time, the mobile terminal draws the sliding trace in the last image frame at the sliding termination location, and completes the entire drawing process.
In this embodiment, firstly, obtain the overall sliding distance and the overall sliding time, draw a sliding trace in the current image frame at the sliding start location and record the current time point when the drawing of the current image frame is completed; on the condition that the drawing time is less than the overall sliding time, obtain a current sliding distance, reset the sliding start location as the sum of the sliding start location and the current sliding distance, repeatedly perform the drawing of subsequent image frames until the drawing time is greater than or equal to the overall sliding time, and draw a sliding trace in the last image frame at the sliding termination location. Compared with the method for achieving a sliding operation by using the system controls, the drawing time and sliding action in this embodiment can be customized and then be obtained by the mobile terminal, thus implementation of various sliding interactions can be achieved, thereby improving the degree of the user experience.
In addition, since the inertia formula is additionally used in the process for calculating the current sliding distance, the sliding operation performed by the mobile terminal exhibits a better fluency and real experience, thereby improving the degree of the user experience.

D) obtaining a current sliding distance according to the drawing time, the overall sliding time and the overall sliding distance, resetting the sliding start location as the sum of the sliding start location and the current sliding distance, and returning to step B; and
E) drawing, at the sliding termination location, a sliding trace in the last image frame.
The graphic user interface in this embodiment firstly obtains the overall sliding distance and the overall sliding time, draws a sliding trace in the current image frame at the sliding start location and records the current time point when the drawing of the current image frame is completed; on the condition that the drawing time is less than the overall sliding time, it obtains a current sliding distance, resets the sliding start location as the sum of the sliding start location and the current sliding distance, repeatedly performs the drawing of subsequent image frames until the drawing time is greater than or equal to the overall sliding time, and draws a sliding trace in the last image frame at the sliding termination location. Compared with methods for achieving a slid by using system controls, the drawing time and sliding action in this embodiment can be customized and then be obtained by the mobile terminal, thus implementation of various sliding interactions can be achieved, thereby improving the user experience.
In addition, since the inertia formula is additionally used in the process for calculating the current sliding distance, the sliding operation performed by the mobile terminal exhibits a better fluency and real experience, thereby improving the degree of the user experience.
