FIG. 1 is a diagram illustrating system 100 for dynamic webpage change animation, in accordance with an exemplary embodiment of the present invention. System 100 comprises client computer device 110, web server 120, and network 130 which connects client computer device 110 and web server 120. Client computer device 110 includes web browser 112, change animation program 114 for animating changes of items on a second or new version of a webpage relative to a first or previous version of the webpage, and user interface 116. Web server 120 includes web user interface 122 to process requests of client computer device 110 for requested webpages hosted on website 124.
Change animation program 114 on client computer device 110 operates in conjunction with web browser 112. While change animation program 114 in the exemplary embodiment is a separate component, change animation program 114 in other embodiments may be fully integrated with web browser 112. In response to that client computer device 110 receives the second or new version of the webpage, change animation program 114 detects one or more items (e.g. HTML forms, links, etc) on the second or new version of the webpage that are changed. The changes of the one or more items on the second or new version of the webpage is relative to the first or previous version of the webpage most recently visited by a user of client computer device 110. The changes of the one or more items include adding one or more new items on the new version of the webpage, excluding from the second or new version of the webpage one or more items which are on the first or previous version, or changing previous item locations on the first or previous version to new item locations on the second or new version of the webpage. Change animation program 114 animates the changes on the second or new version of the webpage relative to the first or new version of the webpage. To detect changed items and to animate the changes, change animation program 114 uses history data of the webpage cached on client computer device 110 or logged on web server 120. The speed of animating the changes is adjusted by settings of change animation program 114. The settings of change animation program 114 can be configurable by the user of client computer device 110. The speed of animating the changes can be also adjusted by the user during a runtime of change animation program 114. Based on one or more factors of user's knowledge, current context, and applications in use, change animation program 114 determines an animation order of changing the one or more items. When more than one of the factors is used for determining the animation order, change animation program 114 gives different weights to the different factors or prioritizes the factors. The weights or how to prioritize the factors are controlled by a user through configuring the settings of change animation program 114 or through runtime control. Operational steps of change animation program 114 are discussed in great detail in later paragraphs with reference to FIG. 2.
Web browser 112 on client computer device 110 is a program that enables users to view, watch, or listen to documents and other resources, such as audio and video files, retrieved from a network device. In the exemplary embodiment, web browser 112 requests for webpages, identified by their URLs (uniform resource locators), from web server 120 via network 130. Web browser 112 on client computer device 110 transmits requests to web user interface 122 on web server 120 for the webpages contained on website 124 hosted by web server 120. Web user interface 122 responds to the requests by retrieving the webpages from website 124 and transmitting them back to web browser 112. User interface 116 on client computer device 110 includes components used to receive input from a user and transmit the input to web browser 112 and/or change animation program 114.
In the exemplary embodiment, change animation program 114 is on the client side, i.e., client computer device 110. However, in other embodiments, change animation program 114 is on the server side, i.e., web server 120.
FIG. 2 is a flowchart illustrating operational steps of dynamic webpage change animation, in accordance with an exemplary embodiment of the present invention. The operational steps of dynamic webpage change animation are implemented by change animation program 114. At step 201, change animation program 114 detects one or more items that are changed on the second (or new) version of the webpage. The change of the one or more items on the second (or new) version of the webpage is relative to a first (or previous) version of the webpage. The changes of the one or more items include adding one or more new items on the second (or new) version of the webpage, removing from the second (or new) version of the webpage one or more items existing on the first (or previous) version, or changing from previous item locations on the first (or previous) version to new item locations on the second (or new) version of the webpage. Change animation program 114 detects the one or more items that are changed by comparing the first (or previous) and the second (or new) versions of the webpage. When comparing the first (or previous) and the second (or new) versions of the webpage, change animation program 114 retrieves a copy of the first (or previous) webpage cached on client computer device 110 or logged on web server 120.
At decision block 203, change animation program 114 determines whether the one or more items are found. In response to determining that the one or more items are not found (NO branch of decision block 203), change animation program 114 terminates its operation. In response to determining that the one or more items are found (YES branch of decision block 203), at step 205, change animation program 114 acquires data of user environment. The user environment includes at least one of context, keywords, and applications currently used by a user. At step 207, change animation program 114 determines an animation order of changing the one or more items, based on the data of the user environment. For example, if the data of the user environment indicates that the user uses one item on a webpage more frequently than other items on the same webpage, change animation program 114 gives the frequently used item more priority in the animation order; in other words, change animation program 114 determines to animate the change of the more frequently used item before the other items. An example of determining the animation order of changing the one or more items is discussed in a later paragraph with reference to FIG. 4A.
At step 209, change animation program 114 displays the first (or previous) version of the webpage. The first (or previous) version of the webpage is cached on client computer device 110 or logged on web server 120. At step 211, change animation program 114 displays a template for generating the second (or new) version of the webpage. For example, change animation program 114 displays the first (or previous) version of the webpage and the template side by side. The template keeps all other items of the first (or previous) version but without the one or more items that are changed.
At step 213, according to the animation order determined at step 207, change animation program 114 animates a change of a respective one of the one or more items. For example, on the first (or previous) version of the webpage and the template which are displayed side by side, change animation program 114 shows how the change occurs from the first (or previous) version to the second (or new) version of the webpage. An example of animation of changing the one or more items is discussed in later paragraphs with reference to FIGS. 4A-4G.
At decision block 215, change animation program 114 determines whether animation of each of the one or more items in the animation order is finished. In response to determining that animation of each of the one or more items in the animation order is not finished (NO branch of decision block 215), change animation program 114 reiterates step 213. In response to determining that animation of each of the one or more items in the animation order is finished (YES branch of decision block 215), change animation program 114 terminates the operation.
FIG. 3 is an example of an animation order of changing items on webpage 300, in accordance with an exemplary embodiment of the present invention. In this example, on the first (or previous) version of the webpage (numeral 300), five items are to be changed on the second (or new) version of the webpage. Item 301 (“Search support and downloads” section) is used frequently by the user; thus, change animation program 114 determines that item 301 is the first one to be animated. Item 302 (“Choose a product” section) is recently used by the user; thus, change animation program 114 determines that item 302 is the second one to be animated. Items 303 and 304 are used less than item 302, and item 303 is used more than item 304; therefore, change animation program 114 determines that item 303 is the third one to be animated and item 304 is the fourth one to be animated. Item 305 is a new item to be added on the second (or new) version of the webpage and may not relate to user's keywords, applications, or context currently used, so that change animation program 114 determines that item 305 is the last one to be animated.
FIGS. 4A-4G illustrate an example of dynamic webpage change animation of different items in the animation order shown in FIG. 3, in accordance with an exemplary embodiment of the present invention. In this example, change animation program 114 first displays the first (or previous) version (numeral 300) of the webpage and template 410 for generating the second (or new) version of the webpage, as shown in FIG. 4A. Change animation program 114 displays the first (or previous) version (numeral 300) of the webpage after retrieving a copy of the first (or previous) version cached on client computer device 110 or logged on web server 120. The template (numeral 410) does not show items 301, 302, 303, 304, and 305 which are to be changed, but shows all other items which are not to be changed.
FIG. 4B shows that the new location of item 301 on template 410 is different from the location of item 301 on the first (or previous) version (numeral 300). Change animation program 114 animates item 301 moving from the location on the first (or previous) version (numeral 300) to the new location on template 410. The relocation of item 301 follows a path indicated by dashed-line 421. FIG. 4C shows that the new location of item 302 on template 410 is different from the location on the first (or previous) version (numeral 300). Change animation program 114 animates item 302 moving from the location on the first (or previous) version (numeral 300) to the new location on template 410. The relocation of item 302 follows a path indicated by dashed-line 431. FIG. 4D shows that the new location of item 303 on template 410 is different from the location on the first (or previous) version (numeral 300). Change animation program 114 animates item 303 moving from the location on the first (or previous) version (numeral 300) to the new location on template 410. The relocation of item 303 follows a path indicated by dashed-line 441. FIG. 4E shows that the new location of item 304 on template 410 is different from the location on the first (or previous) version (numeral 300). Change animation program 114 animates item 304 moving from the location on the first (or previous) version (numeral 300) to the new location on template 410. The relocation of item 304 follows a path indicated by dashed-line 451. FIG. 4F shows addition of item 305 which is a new item on the second (or new) version of the webpage. Change animation program 114 shows content 461 of new item 305 on the top of template 410 and animates content 461 of new item 305 moving into template 410. Content 461 of new item 305 moves into template 410 following a path indicated by dashed-line 462. For removal of an item, change animation program 114 may animate the removal by showing disappearance of the item on the first (or previous) version (numeral 300) or by showing the item's moving to a symbolized area such as a garbage can. FIG. 4G shows both the first (or previous) version (numeral 300) and the second (or new) version (numeral 450) of the webpage. After the animation, change animation program 114 shows all the changed items on the second (or new) version (numeral 450) of the webpage.
