1. Field of the Invention
The present invention relates to a method and medium for variably arranging content menu and a display device using the same, and more particularly, to a method and medium for variably arranging a content menu and a display device using the same, in which a touch sensor having a touch screen detects position information of a user's finger, who holds a front surface or both corners of the touch screen, and arranges menu icons near the user's finger to variably manipulate the content menu.
2. Description of the Related Art
Examples of prior art publications relating to a display device of a touch screen include US Patent Unexamined Publication No. 2004-0130576, Korean Patent Unexamined Publication No. 2004-0050541, and US Patent Unexamined Publication No. 2004-0100479.
The US Patent Unexamined Publication No. 2004-0130576 discloses a method for displaying a screen, in which an output image screen is combined with a manipulation image screen without overlap by a reduction or compression technique using a touch panel which does not shield a source image signal of a touch screen when a manipulation image screen including a manipulation button is displayed on the touch screen.
The US Patent Unexamined Publication No. 2004-0100479 discloses a display control method of an information terminal, in which a menu panel for displaying a menu item sets a predetermined moving track in a three-dimensional virtual space to obtain different kinds of transparency and a specific menu is three-dimensionally displayed in the panel if scrolling is manipulated.
The Korean Patent Unexamined Publication No. 2004-0050541 discloses a portable terminal whose display unit can be controlled in its size as shown in
The aforementioned prior are publications are similar to one another in that they vary the size of the display unit depending on their use states. However, the prior art publications simply display the output image and the manipulation image displayed in the touch screen without overlap, three-dimensionally display a specific menu in a panel or vary the size of the screen or the size of the image depending on movement of the slider. The prior art publications do not variably arrange a menu icon depending on the position of a user's finger touched on the display screen.
Miniaturization of a portable device serves as an important factor because the portable device needs simple portability. In this respect, it is important to effectively arrange a small display window and a menu manipulator. However, since the display unit of the conventional portable device has a physically fixed manipulation area, it is difficult to vary the size of the menu manipulator and its arrangement position suitable for user's circumstances.
Additional aspects, features and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.
Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art. The present invention provides a method and medium for variably arranging a content menu and a display device using the same, in which a touch sensor detects position information of a user's finger, who holds a front surface or both corners of a touch screen, and arranges a menu icon near the user's finger to variably manipulate a menu manipulation area in accordance with the position of the user's finger.

These and/or other aspects, features, and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. Exemplary embodiments are described below to explain the present invention by referring to the figures.
The display device using the method for variably arranging a content menu, as shown in
The position information detection unit 100 detects position information of a user's finger touched with a touch screen. This position information detection technique (method) is shown in
In
In an exemplary embodiment of the present invention, when the user's finger is touched with the touch screen, a sensor provided in the touch screen senses the user's finger and arranges menus near the touch screen as shown in
The finger touch area A means an area that the user's finger is touched with the touch screen. The menu arrangement area B means an area that menu icons can be arranged around the user's finger. The finger touch area A to be displayed in the screen should be prescribed by a general standard because users' finger areas are too various to set a definite area. For example, the finger touch area A can be set within the range that a circle having a diameter of 0.5 cm to 1.5 cm or a circle such as a minimum circle having the width of the forefinger and a maximum circle having the width of the big finger is set using a coordinate value recognized by the user's finger touch as a central point. The menu arrangement area B can be set as an area obtained by subtracting the area A from a circle obtained by adding a diameter length of a menu icon to be arranged on the area B to a diameter length of the area A. At this time, since the diameter length of the menu icon is not absolutely required, the menu arrangement area B is optimized depending on the size of a display window and the number of menus.
Meanwhile, the area setting unit 200 serves to set an attention area depending on the position information detected by the position information detection unit 100.
The attention area means that the user unconsciously pays attention to the finger's periphery if its finger is touched with the touch screen. The attention area may be a peripheral area around the user's finger or a fan shaped area having a certain angle around the user's finger. The attention area is divided into first to n-th attention areas depending on the attention level. The first attention area is the highest attended area, and the second attention area is the second attended area. The attention area is generally called the n-th attention area. The attention area does not have the same concept as that of the menu arrangement area B of
The area setting unit 200 sets an area within a certain distance from the user's finger touched with the touch screen as the first attention area, and also sets an area adjacent to the first attention area within a certain distance from the first attention area as the second attention area. In this way, the area setting unit 200 sets the first to n-th attention areas as shown in an upper side at the left of
Furthermore, the area setting unit 200 sets an area within a certain angle from both directions around the user's finger touched with the touch screen as the first attention area, and also sets an area adjacent to the first attention area within a certain angle from both directions around the first attention area as the second attention area. In this way, the area setting unit 200 sets the first to n-th attention areas as shown in an upper side at the right of
The nearest corner determining unit 210 determines the nearest corner of the touch screen to determine a reference line for menu arrangement. The nearest corner means one of corners at both sides of the touch screen, which is the nearest one to the coordinate value showing the position of the user's finger. If the determined reference line for menu arrangement is the right corner of the touch screen, the nearest corner determining unit 210 serves to set it as L1. If the determined reference line for menu arrangement is the left corner of the touch screen, the nearest corner determining unit 210 serves to set it as L2. L1 and L2 are set to determine a menu arrangement direction for the sake of convenience. The menu arrangement direction will be described later.
The menu control unit 300 serves to arrange menu icons in the attention area set by the area setting unit 200. The menu control unit 300 includes four elements, which will be described below.
The determining unit 310 determines whether the circumference of the menu arrangement area where the menu icons are arranged is included in a part below the upper corner of the touch screen. Also, the determining unit 310 sets S1 if the circumference of the menu arrangement area is not included in the part below the upper corner of the touch screen. The determining unit 310 sets S2 if the circumference of the menu arrangement area is included in the part below the upper corner of the touch screen.
Meanwhile, the start/end point determining unit 320 determines a start point and an end point of the menu icon arrangement depending on the determined result of the determining unit 310.
In the case of S1, the start/end point determining unit 320 sets an intersection point between the upper corner of the touch screen and the circumference as the start point and an apex in a diagonal direction of the start point as the end point if an intersection point between the circumference and both corners of the touch screen does not occur.The start/end point determining unit 320 sets an intersection point between the upper corner of the touch screen and the circumference as the start point and an intersection point occurring in the nearest corner as the end point if an intersection point between the circumference and the nearest corner of both corners of the touch screen occurs.
Further, in the case of S2, the start/end point determining unit 320 sets an intersection point between the circumference and the nearest corner as a start point and an end point if the intersection point occurs and sets the intersection point occurring in the nearest corner as a start point and an intersection point occurring in the lower corner as an end point if the intersection points occur in both the nearest corner and the lower corner. The start/end point determining unit 320 sets an apex between the nearest corner of both corners of the touch screen and the upper corner as a start point and an apex between the nearest corner and the lower corner as an end point if no intersection point between the circumference and the corners of the touch screen occurs.
The menu arrangement determining unit 330 serves to determine arrangement of the menu icons from the start point to the end point, which are determined by the start/end point determining unit 330. The arrangement direction determined by the menu arrangement determining unit 330 is divided into two types, a counterclockwise direction in the case of L1 and a clockwise direction in the case of L2.
The menu arrangement unit 340 serves to arrange the menu icons in accordance with the arrangement direction determined by the menu arrangement determining unit 330. The menu arrangement unit 340 arranges the menu icons considering the first to n-th attention areas along with first to n-th access areas divided depending on the user's access easiness level.
Furthermore, the menu arrangement unit 340 may arrange menus in various lines. In this case, a higher menu icon is first arranged in a first access area. However, the higher menu icon is arranged again in a second access area at a lower menu icon. Therefore, the lower menu icon generated by selecting one menu of the higher menu icon is arranged in the first access area. The access area means a level showing how fast the user's finger or a digitizer pen accesses the menu icons.
Referring to
The angle detection unit 220 sets L1 if the user's finger detected by the scan result has a left orientation angle around a vertical axis of the touch screen while sets L2 if the user's finger has a right orientation angle. This is shown in
The method for variably arranging a content menu in accordance with the pressure and infrared matrix techniques will be described with reference to
First, the position information detection unit 100 should detect the position information of the user's finger touched with the touch screen. In the case of the pressure technique, the pressure point of the user's finger touched with the touch screen is calculated as the coordinate value S302, and the position information is detected in accordance with the calculated coordinate value S304. In the case of the infrared matrix technique, the area of the user's finger touched with the touch screen and a central point of this area are calculated as a coordinate value using infrared rays emitted from the peripheries of the touched part S302, and the position information is detected in accordance with the calculated coordinate value S304.
In the case of the photo scan technique, the image sensing unit 110 scans the user's finger touched with the touch screen on the rear surface of the touch screen to sense an image S502. And, the position information detection unit 100 detects the shape of the user's finger and position information using the image sensed by the image sensing unit 110 S504.
The next steps will be performed equally in the pressure technique, the infrared matrix technique, and the photo scan technique. Therefore, the next steps will be described together with reference to
The area setting unit 200 sets the attention area in accordance with the position information detected by the position information detection unit 100 S306.
As mentioned above, the attention area means an area showing the user's attention level to the touch screen around the user's finger. The attention area may be divided into various areas in accordance with the attention level. In an exemplary embodiment of the present invention, the attention area is divided into various areas in accordance with two examples of the attention level.
In one example, an area within a certain distance plus the diameter length of the menu to be arranged in the touch screen based on the pressure point of the user's finger touched with the touch screen is set as a first attention area, and an area adjacent to the first attention area within a concentric circle plus the diameter length from the first attention area is set as a second attention area. In this way, the first to n-th attention areas can be set.
In the other example, a fan shaped area within a certain angle of both directions around the user's finger touched with the touch screen is set as a first attention area, and a new area adjacent to the first attention area within a certain angle of both directions from the first attention area is set as a second attention area. In this way, the first to n-th attention areas can be set.
In the case of the pressure and infrared matrix techniques, the nearest corner determining unit 210 determines the nearest corner to the position of the coordinate value among both corners of the touch screen. Also, the nearest corner determining unit 210 determines the nearest corner as a reference line for menu arrangement, and sets L1 if the determined reference line for menu arrangement is a right corner of the touch screen while sets L2 if the determined reference line for menu arrangement is a left corner of the touch screen S308.
In the case of the photo scan technique, the angle detection unit 220 sets L1 if the user's finger detected by the scan result has a left orientation angle around the vertical axis of the touch screen while sets L2 if the user's finger has a right orientation angle S508.
The menu control unit 300 arranges menu icons in accordance with the attention area set by the area setting unit 200. This will be described below.
The determining unit 310 determines whether the circumference of the menu arrangement area where the menu icons are arranged is included in a part below the upper corner of the touch screen. Thus, the determining unit 310 sets S1 if the circumference of the menu arrangement area is not included in the part below the upper corner of the touch screen while the determining unit 310 sets S2 if the circumference of the menu arrangement area is included in the part below the upper corners of the touch screen S310 and S510. S1 and S2 are set for the sake of convenience.
The start/end point determining unit 320 determines the start point and the end point of the menu icon arrangement depending on the determined result of the determining unit 310 S312 and S512. This is shown in
In the case of S1, the circumference of the menu arrangement area B is not included in the part below the upper corner of the touch screen as shown in
In the case of S2, the circumference of the menu arrangement area B is included in the part below the upper corner of the touch screen as shown in
Next, the menu arrangement determining unit 330 determines arrangement of the menu icons from the start point to the end point. In this case, the menu arrangement determining unit 330 is required to determine whether the menu icons come under L1 or L2 S314 and S514. In the case of L1, the menu icons are arranged counterclockwise S316 and S516. In the case of L2, the menu icons are arranged clockwise S318 and S518. This is shown in
The menu arrangement unit 340 arranges the menu icons in accordance with the determined arrangement. In this case, the menu icons should be arranged considering the attention area and the access area S320 and S520.
Particularly, referring to
Referring to
The aforementioned menu arrangement is shown in
It is apparent that the present invention may be embodied in a computer programmable recording medium that can record the aforementioned exemplary embodiments of methods for variably arranging a content menu using a computer.
Meanwhile, exemplary embodiments of methods of the present invention may be realized in the case where the user's finger is touched with the front surface of the touch screen. Also, exemplary embodiments of methods of the present invention may be realized in the case where the user's finger is touched with the corner part of the touch screen as shown in
If the position information detection unit 100 detects position information of the user's finger touched with the corner of the touch screen S1502, the area setting unit 200 sets the attention area in accordance with the position information detected by the position information detection unit 100 S1504.
In this case, the attention area is set differently from the aforementioned menu arrangement on the front surface of the touch screen. In other words, the first attention area is set to arrange the menu icons in a line along the corner of the touch screen touched with the user's finger, and an area adjacent to the first attention area within an area plus the diameter length of the menu to be arranged in the touch screen based on the first attention area is set as the second attention area. In this way, the first to n-th attention areas are set.
The menu control unit 300 arranges the menu icons in accordance with the attention are set by the area setting unit 200 S1506. At this time, the menu icons are arranged in a line along the attention area, and a menu concealment icon is additionally arranged if the n-th attention area does not have any sufficient space where the menu icons are to be arranged in a line. This is shown in
It is apparent that exemplary embodiments of the present invention may be embodied in a computer programmable recording medium that can record exemplary embodiments of methods for arranging a content menu by detecting position information of the user's finger touched with the corner of the touch screen.
As described above, in exemplary embodiments of methods for variably arranging a content menu and the display device using the same according to the present invention, since the menu icons are arranged in the area near the user's finger by sensing the position of the user's finger touched with the touch screen, the manipulation position of the menu is not limited and the menu can efficiently be manipulated. Also, since there is no area covered by the user's finger, it is possible to variably manipulate the menu.
Moreover, the menus are arranged in the priority order of the menu manipulation considering the user's attention level and the access level, and efficient retrieval of information can be made.
In addition to the above-described exemplary embodiments, exemplary embodiments of the present invention can also be implemented by executing computer readable code/instructions in/on a medium, e.g., a computer readable medium. The medium can correspond to any medium/media permitting the storing and/or transmission of the computer readable code.
