Abstract
In a touchscreen approach to display of an animated sequence, a display area takes up less than all of the area of a display screen. The user touches the display area and moves the touch in a first direction. This causes the display area to move in a corresponding fashion, and during such motion, the animated sequence is displayed in a first time sequence within the display area. Movement by the user of the touch in the opposite direction may also cause the display area to move in a corresponding direction, and during such motion, the animated sequence is displayed in the opposite time sequence.
Description
The recent great popularity of smart phones and tablets has prompted many investigators to try to devise better user interfaces for display of animations and video. Most such user interfaces are little more than the porting of current user interfaces from desktop computer systems and notebook computer systems. A typical such current user interface has the user starting and stopping the rendered animation or video by touching a play or pause icon on a touch screen. This is sometimes called “click to play”. Such a current user interface is not very flexible in terms of the types of user input and control that may be responded to. Another typical current interface is “auto play” in which the animation or video plays automatically after the page (data file) has finished loading. This interface is often employed for example with animated GIF images. Still another current user interface， sometimes called “scroll to trigger automatic playback) responds to the user picking a location on a time line (either by tapping or scrolling) and the video starts playing automatically from that point in time.
These approaches all offer disadvantages. With these current approaches the user cannot freely control the playback process (for example with a GIF animation) . Or additional controls must be provided to control playback， for example with a player progress bar， controls which take up display screen real estate and are not very intuitive for the user to use. The user attempting to touch and scroll on the player progress bar will (in many current implementations) result in an interruption of the displayed video or animation， and the displayed video or animation only resumes later in a discontinuous fashion.
Summary of the invention
In a touchscreen approach to display of an animated sequence， a display area takes up less than all of the area of a display screen. The user touches the display area and moves the touch in a first direction. This causes the display area to move in a corresponding fashion， and during such motion， the animated or video sequence is displayed in a first time sequence within the display area. Movement by the user
of the touch in the opposite direction may also cause the display area to move in a corresponding direction， and during such motion， the animated or video sequence is displayed in the opposite time sequence.
Description of the drawing
The invention is described with respect to a drawing in several figures.
Figure 1a shows a first display according to the invention.
Figure 1b shows a second display according to the invention.
Figure 1c shows a third display according to the invention.
Figure 1d shows a fourth display according to the invention.
Figure 2 shows exemplary hardware with which the invention may be carded out.
Figures 3a and 3b show offset calculations according to the invention.
Figures 4a， 4b， 4c， and 4d show a sequence of events in a fifth embodiment of the invention.
Turning now to Figures 1a， 1b， 1c， and 1d， we see a sequence of events. We see a consumer electronics device 16 which may for example be a smart phone or a tablet. The device has a touch-sensitive display screen 17.
In Figure 1a we see a display area 12a in a first position on the display screen 17. It will be appreciated that the display area 12a comprises less than all of the area of the display screen 17. In Figure 1a the display area 12a displays a first frame of a multiframe animated sequence 11a.
Figure 1a shows at 13a a user touching the screen 17 at a touch point 15. (The touch point 15 is denoted in Figure 1d.) The user moves the touch point 15 upward in the figures， and as shown in Figure 1b the touch point has moved upwards as shown at 13b.
Responsive to the movement of the touch point due to the touch of the user at the display area 17， the display area location 12b has moved upward correspondingly from the location of the display area 12a. The response further comprises displaying a second frame 11b of the multiframe animated sequence.
Figure 1c shows what happens when the touch point 15 has moved upwards even further than the movement shown in Figure 1b. The display area location 12c has moved upward correspondingly according to the moving of the touch point 15. The response further comprises displaying a third frame 11c of the multiframe animated sequence.
Figure 1d shows what happens when the touch point 15 has moved upwards even further than the movement shown in Figure 1c. The display area location 12d has moved upward correspondingly according to the moving of the touch point 15. The response further comprises displaying a fourth frame 11d of the multiframe animated sequence.
The multiframe animated sequence shown in Figures 1a， 1b， 1c and 1d is a sequence showing a bird in flight. It will be appreciated that the sequence may show other things such as actions of sports figures playing a sporting game.
The sequence of events shown in Figures 1a， 1b， 1c and 1d shows a user input as a touch point moves upwards and the result is that the display area location likewise moves upward and the animated sequence moves forward in time. It is convenient to configure the device 16 so that the opposite is also possible. By this is meant that a sequence could be from Figure 1d to Figure 1c and further to Figure 1b and finally to Figure 1a. With such a sequence the animated sequence moves backward in time. The user could thus move the touch point 15 upwards and downwards repeatedly and could watch as the animated sequence moves forward and backward repeatedly in time.
The embodiment shown in Figures 1a， 1b， 1c and 1d shows a first embodiment in which “upward” movement of the user touch point bringing about “forward” movement in time for the displayed animated sequence and “downward” with “backward”. It will be appreciated that this is quite arbitrary in the sense that there could be a second embodiment in which “downward” movement of the user touch point brings about “forward” movement in time for the displayed animated sequence and “upward” with “backward”.
It will be further appreciated that there could be a third embodiment in which “rightward” movement of the user touch point brings about “forward” movement in time for the displayed animated sequence and “leftward” with “backward”. There could likewise be a fourth embodiment in which “leftward” movement of the user touch point brings about “forward” movement in time for the displayed animated sequence and “rightward” with “backward”.
Figure 2 shows typical hardware 41 with which the claimed invention may be carried out. A processor 34 is connected by means of a display driver 33 to a display 31. Touch-sensitive circuitry 32 provides touch-screen inputs to the processor 34. Processor 34 contains a general-purpose processor or microprocessor 35， a digital signal processor 36， and a graphics processor or accelerator 37. Processor 34 is linked by a communications link with random access memory (RAM) 40. A radio frequency (RF) front end 38 connects the antenna 42 with the processor 34. An RF power circuit 39 permits the processor 34 to transmit RF energy at the antenna 42. Other hardware components including battery， charging circuit， and input-output devices are omitted for clarity in the view of Figure 2.
The method may be carried out by means of a suitable program loaded into RAM 40， making reference to an animated sequence which may be loaded into RAM 40 from local storage (e.g. read only memory (ROM)) or an online server (omitted for clarity in Figure 2). The stored program uses graphics processor or accelerator 37 to drive display driver 33 which puts the desired images onto the display 31. User touch inputs at the screen 31 are detected by circuitry 32 and provided to the processor 34 for use by the stored program. The hardware together with the stored program provides means which carry out the various steps.
The discussion above refers to an animated sequence， which is intended to encompass as well a video sequence. The form of storage may， for example， be PNG image sequences， JPG picture sequences， animated GIF images， and MP4 video files.
The touch by the user is described as being a touch at the display area， for example by means of touch location 15. It will be appreciated， however， that the touch that brings about the results described here may instead be a touch at a scroll bar 14. It will further be appreciated that the touch may be at a pointing device wheel such as a mouse wheel. In any of these approaches， one aspect of the user experience is that the display area for the animated sequence is less than all of the display screen and the display area moves in one direction or another corresponding to the display of the animated sequence forward or backward in time.
Preferably the display of frames of the multiframe animated sequence is continuous in response to continuous motion by the user in the touch movement. Preferably this continuous display in response to continuous motion by the user in the touch movement works both forward in time display and backwards in time display， and the progress and speed of the continuous display is monotonically related to the progress and speed of the user touch movement. Ideally the progress and speed of the continuous display is directly proportional to the progress and speed of the user touch movement. When the user touch input movement stops， the animated display pauses.
Figures 3a and 3b show offset calculations according to the invention. In these figures we can see the display screen 66 and within it a movable display area 67 which， as previously mentioned， comprises less than all of the area of the display screen 66.
A first frame of the animated sequence is displayed in Figure 3a. In this figure the display area 67 may be so low on the screen 66 that a bottom portion of the display area 67 is not visible to the user. Saying this in a different way， the start position 62 for the display area is less than or equal to the scroll position 61. The start position and scroll position may be conveniently measured as integer values of pixel positions on the screen.
In Figure 3b， the user has conducted a touch movement that has moved upwards. This defines an
offset 65 which is determined by subtracting the scroll position 64 from the start position 63. The offset is used， as will now be described， to pick which frame of the animated sequence will be displayed.
The number of frames of animation is used to work out a step size 66. The offset， divided by the step size， is used as a frame number to determine which frame is being displayed.
Figures 4a， 4b， 4c， and 4d show a sequence of events in a fifth embodiment of the invention. In this embodiment， a page has multiple animations. The user can scroll up and down (or left and right in a related embodiment) and this controls the playback. A first animation 61a， 61b， 61c， and 61d may be seen as a result of the user scrolling. In addition， a second animation 62a， 62b， 62c， and 62d may also be seen as a result of the same user scrolling.
The alert reader will have no difficulty devising myriad obvious improvements and variations of the invention， all of which are intended to be encompassed within the claims which follow.
