Description

  The present invention relates to a portable information device having a selection menu display function, a selection menu display method, a selection menu display program, and a program recording medium.

In a portable communication terminal that performs an input operation by touching a touch panel formed by laminating a display device and a transparent position input device with a finger,
・ Lightweight by thinning and minimizing the outer frame area of the screen ・ Improvements such as improving visibility by increasing the screen size are progressing.

  Along with such improvements, the number of operation buttons has been reduced and operability with one hand has been improved from the viewpoint of improving portability.

For example, in an internet browser:
・ Visit and return of browsing sites (forward, back)
・ Display a list of pre-registered sites and select sites (bookmarks)
・ Browsing history reference (history)
・ Re-acquisition (reload) of site data
・ Option selection (setting) related to display and operation
For each operation, a function selection menu is displayed, and each function is executed by allowing the user to make a selection.

  However, in the screen display of the Internet browser, since the arrangement of buttons and links varies depending on the browsing site, it is not best to assign the function selection menu display to a fixed position.

  As a solution to such a problem, the display of the function selection menu is not assigned to a specific button (for example, a physical button) but is assigned to a specific touch operation starting from a specific area on the touch panel.

  In the portable communication terminal illustrated in FIG. 4, the function selection menu is displayed for a swipe operation in the center direction of the touch panel 2 starting from the left end of the touch panel 2, for example, with a low possibility of buttons and links being arranged. Assigned. In FIG. 4, FIG. 4 (a) is a front view, and FIG. 4 (b) is a cross-sectional view taken along the line AA 'in FIG. 4 (a). 1 is an outer frame, 2a is the position input device, 2b is the display device, and 3 is a function selection menu. As shown in FIG. 5, when a swipe operation with a finger is started from the end of the touch panel 2, the function selection menu 3 is displayed as shown in FIG.

  According to this operation, operations other than the swipe operation from the end of the touch panel 2 can be used in the browser application. Therefore, the function selection menu display function can be added without obstructing the site browsing operation.

  However, as described above, in a portable communication terminal that pursues weight reduction and visibility improvement, when a quick swipe operation is performed, swipe from the end of the touch panel 2 against the user's intention for the following reason. It is not detected as an operation, and the possibility of being detected as a swipe operation starting from a position slightly closer to the center from the end of the touch panel 2 is increased. Therefore, there is a problem that the function selection menu cannot be displayed as intended by the user.

  Reason 1: As shown in FIG. 6, when the finger 4 is caught on the edge of the outer frame 1 a that has become narrower due to weight reduction and the finger 4 jumps for a moment, the finger 4 is slightly inside the edge of the touch panel 2. It will be a swipe operation after landing. In this case, since the swipe operation is not started from the end of the touch panel 2, the function selection menu is not displayed.

  Reason 2: As shown in FIG. 7, when the upper surface of the outer frame 1 b is slightly shifted upward from the upper surface of the touch panel 2, if a quick swipe operation is performed, the finger 4 moves from the upper surface of the outer frame 1 b. When moving to the upper surface of the touch panel 2, it will land at a position away from the end of the touch panel 2. Also in this case, since the condition for starting the swipe operation from the end of the touch panel 2 is not satisfied, the function selection menu is not displayed.

  In order to cope with the problem that the above-mentioned function selection menu cannot be displayed because the swipe operation from the end of the touch panel 2 is not detected against the user's intention, the “touch panel 2 end” is set as the start point of the swipe operation. It can be considered that the above condition is relaxed to a condition that “from the end of the touch panel 2 within a certain range” is the start point of the swipe operation.

  For example, in an electronic book page turning apparatus disclosed in Japanese Patent Application Laid-Open No. 2012-79315 (Patent Document 1), a preset right UI (User Interface) operation area of a screen on which an electronic book is displayed When touched down on the left side and dragged and touched up in the right direction, the previous page is displayed on the screen. On the other hand, when touched down on the right side from the left UI operation area and dragged and touched up in the left direction, the next page is displayed on the screen.

  Thus, in the electronic book page turning apparatus disclosed in Patent Document 1, the page turning operation is assigned to a touch operation to a specific position in the screen and a specific action. Therefore, when the page turning operation disclosed in Patent Document 1 is applied to the function selection menu display operation in the portable communication terminal, the range of the touch panel 2 that can be used in the browser application is reduced. Drag scrolling is possible only at the center of 2. Therefore, there is a problem that the operability of the browser application is reduced.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 is a functional block diagram showing a functional configuration in a function selection menu display control system for controlling function selection menu display such as an Internet browser in the portable information device of the present embodiment.

  The portable information device is, for example, a smartphone (product name), and has an appearance as shown in FIG. 4 although not shown. And it has the touch panel arrange | positioned on the surface of a housing, the microphone for a call is arrange | positioned under this touch panel, and the speaker for a call is arrange | positioned above the said touch panel.

  In FIG. 1, the touch panel 11 has a display function and an input function. For example, a capacitive position transparent input device and a display device such as an LCD (Liquid Crystal Display) panel are provided. Are laminated. And the control part 12 receives the position signal showing the input position from the said position input device, recognizes an input character, or recognizes the designated function selection menu. Then, a display signal is output to the display device to display an input character string, or an execution result of a designated function selection menu is displayed.

  The contact position detection unit 13 detects the contact position of the finger on the position input device based on the position signal from the position input device of the touch panel 11 sent from the control unit 12. The contact speed detection unit 14 detects the contact speed (operation speed) of the finger with respect to the position input device based on the position signal from the position input device sent from the control unit 12.

  The menu display determination unit 15 determines the user based on the contact start position of the finger detected by the contact position detection unit 13 and the contact speed at the contact start position of the finger detected by the contact speed detection unit 14. It is determined whether or not the operation on the touch panel 11 is an operation for performing the function selection menu display. The menu display unit 16 executes a function selection menu display process for the display device of the touch panel 11 based on the determination result of the menu display determination unit 15.

  And the said control part 12 controls the said touch panel 11, the contact position detection part 13, the contact speed detection part 14, the menu display determination part 15, and the menu display part 16, and performs a function selection menu display control processing operation.

  That is, in the present embodiment, the menu display control unit is configured by the contact position detection unit 13, the contact speed detection unit 14, the menu display determination unit 15, and the menu display unit 16.

  Further, the control unit 12 receives signals from the microphone, operation keys, storage unit, communication unit, etc. (not shown), performs various processes, and sends signals to the speaker, storage unit, communication unit, etc. (not shown). Output.

  In the following, the touch panel 11 is simply referred to as the touch panel 11 without distinguishing between the position input device and the display device.

  Here, the “method for determining whether or not the operation is for displaying the function selection menu” by the menu display determination unit 15 will be described.

In the present embodiment, the menu display determination unit 15 selects a function “swipe operation not from the end of the touch panel 11” that satisfies the determination condition 2 in addition to the conventional determination condition 1 as described below. It is added to the menu display conditions.
-Judgment condition 1: When a swipe operation is performed from the end of the touch panel 11 toward the center of the touch panel 11.
-Judgment condition 2: The swipe operation is started from a position within the set range from the end of the touch panel 11 to the preset distance toward the center of the touch panel 11, and the operation speed at the swipe start point is set in advance. Within the specified speed range.

  When the swipe operation is started from a point slightly closer to the center from the edge of the touch panel 11 as in the determination condition 2 due to the reason 1 shown in FIG. 6 and the reason 2 shown in FIG. The initial speed of the operation detected by the contact speed detection unit 14 is faster than when touching and starting the swipe operation from that point. Therefore, it is added to the determination condition 2 that the swipe start speed is faster than the specific set speed. Also, in the case of an abnormally fast swipe start speed, it is considered as noise and is ignored.

  Hereinafter, a mechanism that increases the initial speed of the operation when the swipe operation is started from a point slightly closer to the center than the end of the touch panel 11 will be described in detail.

That is, an operation of moving a finger by touching the touch panel 11. It can be broken down as follows.
Finger touches touch panel 11 → Finger movement speed gradually increases from 0 Moves finger while touching touch panel 11 → Finger movement speed is almost constant Stops finger touching touch panel 11 → Finger movement speed decreases little by little To 0

  That is, the moving speed of the finger increases from the stop state, and then the moving speed decreases and finally stops.

  Thus, when the vertical axis is time and the horizontal axis is the operation speed (movement speed), the change in the finger operation speed during the swipe operation becomes a curve close to a normal distribution as shown in FIG. 2, for example. Note that the time and operation speed in FIG. 2 are expressed in relative positions.

  In FIG. 2, when a swipe operation is started from a position after the finger touches the touch panel 11, the curve of the finger operation speed starts from the position of the finger touch at time “0”. On the other hand, when the touch panel 11 is touched in the middle of the operation, the curve of the operation speed of the finger is started from, for example, the position of time “3” when the finger has already started moving.

  That is, in the reason 1 shown in FIG. 6 and the reason 2 shown in FIG. 7, the user touches the end of the touch panel 11 and performs the swipe operation, but the touch panel 11 is moved from the middle of the operation. Since the touch is performed, the touch position of the finger is detected in the state of “★” instead of “☆” in the curve shown in FIG.

In this case, the moving speed of the finger is faster in the position of “★” than in the position of “☆” in the curve shown in FIG. there,
-Detecting the start of a finger touch within a set range from the end of the touch panel 11 to a preset position toward the center of the touch panel 11;
Further, the operation speed of the finger at the touch start position is within a set speed range that is larger than the first set speed set in advance and smaller than the second set speed set larger than the first set speed in advance. The above event can be detected on the condition that it exists.

  Here, the above-mentioned “position set in advance toward the center of the touch panel 11” refers to the operation in the reason 1 shown in FIG. 6 and the reason 2 shown in FIG. When the touch panel 11 is touched halfway, the position is set so as to exceed the position of the maximum distance from the end of the touch panel 11 by a predetermined length. In addition, the above-mentioned “preset first set speed” refers to the touch panel 11 during the operation in the reason 1 shown in FIG. 6 and the reason 2 shown in FIG. This is the maximum speed of the finger at the start of touch when touching. Furthermore, the above-mentioned “preset second set speed” is the speed of the finger that is considered to be abnormally fast and noise.

  By the way, the specific hardware configuration of the portable information device having the above functional configuration includes a program memory for storing various programs including programs for executing various processes, a data memory for storing various information, and a communication network such as the Internet. Control the connected communication I / F, input device, output device, display device, program memory, data memory, communication I / F, input device, output device, display device, etc., and execute function selection menu display, etc. It consists of a CPU (Central Processing Unit).
