Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic apparatus such as a PDA, a mobile phone, and a television set, an automatic scrolling method, and a program.
[0002]
[Prior art]
If the entire size of the display of data such as a web page exceeds the size of the screen, the entire data cannot be displayed at once. Therefore, scrolling for moving the display position of data on the screen up, down, left, and right is performed by a user's operation of an input operation unit such as a keyboard and a mouse. Such browsing while scrolling the data in the screen by the operation of the user is called “active browsing” in the sense that the user actively performs the scroll operation. There is also a technique for automatically scrolling data within a screen without relying on a user's operation, and browsing data by such automatic scrolling is called "passive browsing".
[0003]
Known techniques relating to automatic scrolling include, for example, Patent Literature 1 and Patent Literature 2. Patent Literature 1 describes a method of interlocking horizontal scrolling and vertical scrolling, and Patent Literature 2 describes a method of performing automatic scrolling at a speed suitable for a user.

[0038]
FIG. 2 shows a configuration of an area provided in the main memory 2 when the electronic apparatus 100 browses data such as a web page.
[0039]
As shown in the figure, when browsing data, the main memory 2 is provided with a basic program area 21, a web browsing program area 22, a scroll processing program area 23, a page patrol program area 24, a cursor pointer processing program area 25, and the like. .
[0040]
The basic program area 21 is an area in which a basic program for operating the electronic device 100 is stored. The web browsing program area 22 is an area in which a web browsing program for acquiring and browsing a web page from the Internet is stored.
[0041]
The scroll processing program area 23 is an area in which a scroll processing program for processing automatic scrolling of data such as a web page browsed by a web browsing program is stored. Note that this scroll processing program may be integrated into the web browsing program as add-in software or the like.

This tour list can be created by the user.
[0043]
The cursor pointer processing program area 25 is an area in which a cursor pointer processing program for processing display of a cursor pointer for allowing a user to select an arbitrary part on data, such as a link setting part on a web page, is stored. The cursor pointer processing program moves the cursor pointer in a direction instructed by the user in accordance with a command given from the user through the operation input unit 13 or moves the cursor pointer in conjunction with automatic scrolling of data by the scroll processing program. For example, a process of automatically moving to data on the screen updated by automatic scrolling is performed.
[0044]
FIG. 3 is a flowchart showing the overall processing procedure for automatic scrolling by the scroll processing program.
[0045]
As shown in the figure, the scroll processing program stops the timer for generating an automatic scroll interruption if it is running (step 302), and causes the display of data such as a web page to be executed (step 303). ). Thereafter, it is checked whether or not the automatic scroll mode is currently set (step 304). If the automatic scroll mode is set, the timer is started (step 305). If any user control event of “end”, “scroll mode change”, “speed change”, “pause”, or “resume” occurs before the timer interrupt occurs (YES in step 306), the user The control is identified (step 307), and the following processing is performed.
[0046]
When the event of "end" occurs, the end processing of the scroll processing program is performed (step 308). When an event of "scroll mode change" occurs, a scroll mode change process is performed (steps 309-313). If the event of "speed change" occurs, the speed of the automatic scrolling is set (change of the set value of the timer) (step 314). When the "pause" event occurs, the timer is stopped, and a portion of the document being displayed on the screen where a link to another document is inserted (a portion having a link destination) is pointed (step). 315). If an event of "resume" occurs during the pause of the automatic scroll, the timer is started to make the automatic scroll restartable (step 316). Thereafter, the process enters a state of waiting for user control in step 306.
[0047]
In the scroll mode change processing in steps 309-313, first, if the timer is running (YES in step 309), the timer is stopped (step 310), and the scroll mode is set (step 311).
[0048]
Types of scroll modes in automatic scrolling include smooth scrolling that scrolls at a constant speed, page scrolling that scrolls in units of display pages as shown in FIG. 4, and scrolling in units of n lines as shown in FIG. Line scrolling.
[0049]
Thereafter, it is confirmed whether or not the automatic scroll mode is currently set (step 312). If the automatic scroll mode is set, a timer is started (step 313). Thereafter, the process enters a state of waiting for user control in step 306. In the above processing flow, when a timer interrupt occurs (step 317), automatic scroll processing is executed (step 318).
[0050]
FIG. 6 is a flowchart showing the procedure of the automatic scroll process (step 318).
[0051]
After confirming that scrolling has not been completed to the end of the page during automatic scrolling (NO in step 601), the scroll processing program confirms the currently set scroll mode (step 602), and performs smooth scrolling. Control (step 603), page roll-up for page scrolling (step 604), or N-line roll-up for line scrolling (step 605). When the scroll is completed to the end of the page (YES in step 601), the automatic scroll processing ends. This automatic scrolling process is executed one cycle every time a timer interrupt occurs, and is repeated until the user instructs to temporarily stop automatic scrolling.
[0052]
In the automatic scroll processing as described above, the cursor pointer processing program moves the cursor pointer on a page in the screen updated by the automatic scroll in conjunction with the automatic scroll. That is, processing is performed to automatically move the cursor pointer from a position on the data displayed before the start of the automatic scrolling to a position on the data displayed after the automatic scrolling. More specifically, for example, as shown in FIG. 7, after the automatic scrolling, in the link setting portion 71 in which the information of the reading source of the link destination data on the data displayed on the screen 70 is inserted, A predetermined condition on the screen is satisfied, such as a method of moving the cursor pointer 72 to the link setting portion 71 closest to the center of 70, or moving the cursor pointer to the link setting portion closest to the upper left of the screen (not shown). Move the cursor pointer to the position.
[0053]
As a method for determining the link setting portion to which the cursor pointer moves after the automatic scrolling, for example, calculating the positions on the screen of all the link setting portions existing in the data displayed on the screen Then, a method of determining the link setting portion to which the cursor pointer is moved can be considered. In addition, a continuous selection command is issued along the locus of the circle around the base point such as the center or the upper left of the screen, and this is repeated while increasing the size of the circle until a response from the web browsing program is performed. Is used as the destination of the cursor pointer using the link setting portion that has returned the first response. If there is no link setting portion in the data displayed on the screen after scrolling, the cursor pointer may be moved to a predetermined position such as the center or upper left of the screen.
[0054]
The link setting portion where the cursor pointer is located after the automatic scrolling is displayed, for example, with its periphery surrounded by a line different from the background color, for example, a contrasting color line. This allows the user to visually recognize the position of the cursor pointer after moving at a glance. Alternatively, the background color and the character color of the link setting portion may be changed and displayed, or may be displayed blinking.
[0055]
Since the cursor pointer is automatically moved on the data displayed on the screen after the automatic scrolling in this way, it is not necessary to move the cursor pointer by a user operation after the automatic scrolling. The operability of the user when shifting to active browsing by operation is greatly improved.
[0056]
Next, an automatic scroll process when browsing a web page having a frame will be described.
[0057]
8 is an example of a web page having a frame, FIG. 9 is an example of a source of an HTML file forming the frame, and FIG. 10 is a flowchart showing a procedure of a scroll process applied to a web page having a frame.
[0058]
The web page 80 shown in FIG. 8 is defined by the first frame 81 of “top” defined by the line part 91 of the source 90 of the frame file shown in FIG. A second frame 82 of “left” and a third frame 83 of a frame name “main” also defined by a row 93.
[0059]
When a new web page is displayed by the web browsing program (YES in step 1001), the scroll processing program analyzes the source of the HTML file that sets the web page (step 1002), and the web page has a frame. It is determined whether the page is a web page (step 1003). That is, as shown in FIG. 9, when the source includes an HTML file including the <frameset> tag, it is determined that the web page is a web page having a frame.
[0060]
If it is determined that the web page has a frame, the HTML source of the file (frame file) defining the frame is analyzed (step 1004). Scroll frame) is selected (step 1005). The automatic scroll frame selection process will be described later in detail. After the selection of the automatic scroll frame, the currently set scroll mode is determined (step 1006), and the scroll processing of the selected automatic scroll frame is executed for one cycle according to the scroll mode (steps 1007, 1008, 1009).
[0061]
In the next cycle of the scrolling process by the timer interruption, since the web page has already been displayed, the process shifts from step 1001 to step 1010. It is determined whether the web page has a frame (step 1010). If the web page has a frame, the frame selected in step 1005 is set as an automatic scroll frame (step 1011). Thereafter, the scroll mode is determined (step 1006), and the scroll processing of the selected automatic scroll frame is executed for one cycle according to the scroll mode (steps 1007, 1008, 1009). The above-described cycle of the scroll processing is repeated until the scroll reaches the end of the web page (YES in step 1012).
[0062]
FIG. 11 is a flowchart showing the procedure of the automatic scroll frame selection process in step 1005.
[0063]
The scroll processing program checks whether or not the target attribute of the <a> tag exists in the HTML source of the frame file (step 1101). If the target attribute does not exist, the main name such as “main” or “body” is included in the frame name. A frame to which a specific name indicating content is given or a frame having the largest display size is set as an automatic scroll frame (step 1102).
[0064]
If the target attribute of the <a> tag exists in the HTML source of the frame file (YES in step 1101), it is determined whether or not a frame name is set as the value of the target attribute (step 1103). If not, a frame with a specific name such as “main” or “body” added to the frame name or a frame with the largest display size is automatically added to the frame name as described above. A scroll frame is set (step 1102). If a frame name is set as the value of the target attribute, the frame specified by the target attribute is set as an automatic scroll frame (step 1104).
[0065]
For example, in the web page 80 having three frames shown in FIG. 8, since the frame name of the third frame 83 is “main” (see FIG. 9), the third frame 83 is automatically scrolled. The frame is set as a frame, and the cursor pointer is moved with the automatic scroll of the third frame 83.
[0066]
FIG. 12 is a flowchart illustrating a procedure of an automatic scroll process capable of automatically switching pages within an automatic scroll frame.
[0067]
The processing from step 1201 to step 1212 in the procedure of the automatic scroll processing is the same as the processing from step 1001 to step 1012 in the procedure of the automatic scroll processing shown in FIG. 10, but in the automatic scroll processing in FIG. After determining in 1212 that the scroll processing has reached the end of the web page, it is confirmed that the web page that has been automatically scrolled is a web page in a frame (YES in step 1213), and the frame processing (step 1214). ).
[0068]
Next, details of the frame processing will be described.
[0069]
For example, in FIG. 13, when a plurality of characters 132 as a link setting portion are displayed in the left frame 131 and the cursor pointer 133 is positioned at one of the characters 132 and selected, the selected character 132 is displayed. This is an example of a web page 130 having a structure in which a linked web page set to a character 132 is displayed in a frame 134 on the right side.
[0070]
FIG. 14 is an example of a frame file source in the HTML file constituting the web page 130 of FIG. The description portion 141 of the source 140 of the frame file in FIG. 14 defines the contents related to the left frame 131 in FIG. 13, and the description portion 142 similarly defines the contents related to the right frame 134 in FIG.
[0071]
FIG. 15 is an example of the source 150 of the file “left.htm” specified by the <frame> tag in the description part 141 in FIG. That is, this file “left.htm” is a file displayed in the left frame 131 of FIG. In the source 150 of the file “left.htm” shown in FIG. 15, for example, “aaa.htm” is defined as a link destination file for the character “a” which is a link setting portion displayed in the frame 131. The target attribute specifies that the contents of the file “aaa.htm” be displayed in the frame having the name “main”, that is, in the right frame 134.
[0072]
When browsing such a web page 130, the frame processing is executed, for example, as follows.
[0073]
The right frame 134 is determined as the auto-scroll frame. When the automatic scrolling reaches the end of one web page in the right frame 134, the display content of the frame 134 is updated with the link destination web page set in the next link setting portion 132 in the left frame 131. And resume automatic scrolling. That is, the web pages of the respective link destinations set in the respective link setting portions 132 in the left frame 131 are sequentially displayed one by one in the right frame 134, and the automatic scrolling is repeated.
[0074]
Further, the frame processing supports not only switching of the web page within the automatic scroll frame, but also switching of the automatic scroll frame itself.
[0075]
FIG. 16 shows a specific example of switching of data within an automatic scroll frame and switching of the automatic scroll frame itself.
[0076]
FIG. 17 is a source 170 of a frame file (frameA.htm) for generating the web page 161 of FIG. As can be seen from the description of the reference numerals 171, 172, and 173 of the source 170, the web page 161 having a frame includes a “top” frame 165, a “left” frame 166, and a “main” frame 167. Have.
[0077]
FIG. 18 is an example of the source 180 of the content file (top.htm) displayed in the frame 165 of “top”. Here, a link is set for each of the displayed characters "A" and "B". That is, as shown in the description of reference numeral 181 of the source 180, a link to a frame file (frameA.htm) that defines the frame of the web page 164 in FIG. As indicated by reference numeral 182, a link to the frame file (frameB.htm) defining the frame of the web page 164 in FIG. 16 is set for the character “B”. Since “_top” (frame release) is given to these links as the value of the target attribute, the content of the web page 161 is displayed in the frame release state when the character “A” in the frame 165 is selected. When the character "B" is selected, the contents of the web page 164 are displayed in a frame released state.
[0078]
FIG. 19 is a source example of a content file (left.htm) displayed in the frame 166 of “left”. Here, as shown in the description of reference numeral 191, each of the displayed characters "a", "b", "c", "d", and "e" is linked to other data. Is set. That is, a link to a content file (aaa.htm) to be displayed in the frame 166 of the web page 161 is set in the character “a”, and similarly, the characters “b”, “c”, “d”, “ e "also has links to the respective content files (bbb.htm, ccc.htm, ddd.htm, eeee.htm) to be displayed in the frame 166 of the web page 161.
[0079]
FIG. 20 is an example of the source 200 of the content file (main.htm) displayed in the frame 167 of “main”. Here, for example, characters “1”, “2”, “3”,...
[0080]
FIG. 21 is an example of the source 210 of the content file (aaa.htm) as the link destination of “a” in the “left” frame 166. Here, the contents to be displayed, for example, characters “a1”, “a2”, “a3”,... Are described.
[0081]
FIG. 22 is an example of a source 220 of a frame file (frameB.htm) which is a link destination of “B” in the frame 165 of “top”. This defines the frame of the web page 164 of FIG. As can be seen from the description of reference numeral 221 of the source 220 in FIG. 16 and FIG. 22, the web page 164 includes a “top” frame 165 for displaying a content file (top.htm) and a content file (B_main.htm). ) Are provided vertically and separately.
[0082]
When browsing the web pages 161-164 in FIG. 16 as described above, the objects to be automatically scrolled are "main.htm", "aaa.htm", "bbb.htm", "" in the frame 167 by frame processing. ccc.htm ”,“ ddd.htm ”, and“ ee.htm ”in this order. Further, with the frame reconstructed, the automatic scroll target is switched to the frame 168 in the newly constructed web page 164. Then, the web page of "main.htm" is automatically scrolled.
[0083]
In addition, frame processing also supports IFRAME specified in the HTML 4.0 specification. The use of the <IFRAME> tag not only divides the screen or window horizontally and vertically like the <FRAMESET> tag, but also creates an inline frame that is displayed independently in the screen or window. It is possible. FIG. 23 shows an example of a web page 230 using IFRAME. In this example, another frame 232 capable of scroll display is arranged in a frame 231 capable of scroll display. That is, it can be said that one frame 231 includes the other frame 232.
[0084]
As described above, in browsing the web page 230 using IFRAME, the target of automatic scrolling is switched from the included frame 232 to the frame 231 including the same by frame processing.
[0085]
As described above, when switching the automatic scrolling target between frames, the priority is determined based on the analysis result of the source of the frame file, and the automatic scrolling frame is switched according to the priority.
[0086]
FIG. 24 is a flowchart showing a procedure of frame processing in which the above functions are implemented.
[0087]
First, it is determined whether or not the current automatic scroll frame is composed of IFRAME (step 2401). If the frame is composed of IFRAME, it is determined whether or not there is a frame including the current automatic scroll frame (step 2402). If there is no frame containing the current auto-scroll frame, the current auto-scroll frame is a frame (eg, frame 231 in FIG. 23) containing another frame in the web page using IFRAME. It is determined that there is, and the process proceeds to step 2404. Also, if there is a frame including the current auto-scroll frame, the current auto-scroll frame is included in another frame in the web page using IFRAME (eg, frame 232 in FIG. 23). Is determined, the included frame is set as an automatic scroll frame, and the scroll position is set at the head (step 2403).
[0088]
If it is determined in step 2401 that the current automatic scroll frame is not composed of IFRAME (NO in step 2401), or if it is determined in step 2402 that it is composed of IFRAME. If it is determined that there is no frame including the current auto-scroll frame (NO in step 2402), the source of the web page displayed in the current auto-scroll frame is <a It is checked whether the target attribute of the tag exists (step 2404). If the target attribute of the <a> tag does not exist, the presence or absence of an unprocessed frame is checked (step 2405). If there is an unprocessed frame, the unprocessed frame is set as a new automatic scroll frame, and the scroll position is set. It is set at the head of the unprocessed frame (step 2406).
[0089]
If it is determined in step 2404 that the target attribute of the <a> tag is described in the source of the web page displayed in the current auto-scrolling frame, the display content of the frame specified by the target attribute is next. It is determined whether switching is set as valid for the web page of the link destination (step 2407). For this setting, for example, one of the values is determined by default, and the value can be appropriately changed according to the user's preference. If it is set as valid to switch the display content of the frame specified by the target attribute in the linked web page (YES in step 2407), the process proceeds to step 2408, and if it is not set as valid. Shifts to step 2405 to process unprocessed frames.
[0090]
In step 2408, it is determined whether or not the frame name is set in the target attribute in the source of the web page displayed in the current auto-scrolling frame. In step 2409, an unselected link is selected among the links having the target attribute. To determine if something exists. As a result of these steps 2408 and 2409, when it is determined that an unselected link exists, the unselected link is selected (step 2410), and the frame specified by the target attribute is automatically scrolled. Is set to (step 2411). Thereafter, the web page is displayed in the frame set as the automatic scroll frame, and the scroll position is set (step 2412).
[0091]
If it is determined in step 2408 that the frame name is not set in the target attribute, or if it is determined in step 2409 that there is no unselected link, the process proceeds to step 2413. In step 2413, it is determined whether or not “_top” is set as the value of the target attribute. If not, the process proceeds to step 2405 to process an unprocessed frame. If “_top” is set, it is determined whether or not there is an unselected link among the links having “_top” as the value of the target attribute (step 2414). If not, the process proceeds to step 2405 to process an unprocessed frame. If there is an unselected link, the unselected link is selected, and the web page is displayed from the top with the frame released (step 2415).
[0092]
In addition, the automatic scrolling process described above combines a web patrol program that collects web pages from various websites on the Internet in accordance with a pre-created patrol list, so that web pages between different reading sources can be straddled. Automatic scrolling can be switched.
[0093]
In this case, a web page periodically acquired by the page patrol program may be displayed in an automatic scroll frame and automatically scrolled by the main operation of the page patrol program. Then, a page acquisition request may be made to the page patrol program.
[0094]
For example, as shown in FIG. 25, a scroll completion event is issued to the page patrol program when it is determined in step 2405 in FIG. Then, there is a method of requesting the page patrol program to acquire the next web page entered in the patrol list (step 2416).
[0095]
