are satisfied, where the relative positions of the uppermost portion and the lowermost portion of the content or the scroll bar are 0 and 1, respectively.
Next, display control in accordance with the first embodiment of the present disclosure will be described with reference to Fig. 4 to Fig. 8.
First, as shown in the flowchart of Fig. 4, the operation
Next, the process of the content display
However, in this embodiment, in particular, the value of the parameter a is determined in accordance with the difference between the current display position and the target display position in order to increase the operability of the scroll bar. Hereinafter, the value of the parameter a determined in accordance with the difference between the current display position and the target display position will be described with reference to Fig. 7. Note that Fig. 8 is a graph representation of the scroll speed vc(t) of yc (the display position of the content) calculated using the parameter a shown in Fig. 7.
First, a case in which the difference between the current display position and the target display position is below a threshold d1 (a second threshold) will be described. In this case, the amount of movement of the
Next, a case in which the difference between the current display position and the target display position is greater than a threshold d2 (a first threshold), which is greater than the threshold d1, will be described. In this case, the amount of movement of the
Next, a case in which the difference between the current display position and the target display position is a value between the threshold d1 and the threshold d2 will be described. In this case, the value of the parameter a is set to a value that changes vc at an accelerated pace so that the value of the parameter a of (1) and the value of the parameter a of (2) are continuously connected. That is, the value of the parameter a is set to a value determined from a function that changes the value of the parameter a from the value of the parameter a of (2) to the value of the parameter a of (1). For example, the value of the parameter a is determined as represented by the following
is satisfied.
The first embodiment has described a change in the speed of yc (a change in the scroll speed of the display position of the content) in accordance with the positional relationship between yc and ys (the current display position and the target display position). However, as shown in Fig. 8, the smaller the difference between yc and ys (the current display position and the target display position), the lower the speed vc. Thus, even if the knob is moved quickly, the speed is low around the converged value of yc. Thus, vc is made to have inertia. That is, the speed vc(t) of yc at a given point in time t depends on the previous speed vc(t - dt) (speed at the time earlier by the minimum resolvable time dt). Provided that the degree of influence of the speed in the past is x, the current speed can be represented by the following
According to each of the aforementioned embodiments, it is possible to control the properties of following the display position of content in response to an operation of specifying the target display position.
