Therefore, Guide you to choose. This minimizes the error of the user touching objects other than the target object.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, the portable terminal 100 according to the embodiment of the present invention includes a storage unit 10, a display unit 20, a sensing unit 30, and a control unit 40. As shown in FIG. The mobile terminal 100 may be a terminal having the display unit 20 and may be a mobile communication terminal, a notebook, a PDA (personal digital assistant), a portable multimedia player (PMP), a digital multimedia broadcasting (DMB) Video Broadcasting).

The storage unit 10 stores a program necessary for controlling the operation of the portable terminal 100 and data generated during the execution of the program, and is composed of one or more volatile memory devices and nonvolatile memory devices. The storage unit 10 stores an execution program for highlighting and displaying an object on the screen where a touch mechanism such as a finger or a stylus pen (hereinafter referred to as a " touch mechanism " At this time, the object includes an image, a menu, a list, an icon, text, and the like displayed on the screen. The storage unit 10 stores a method of highlighting and displaying the object according to the object type, and the method may be set differently according to the object type. For example, if the object is a menu, the color and brightness are displayed differently. If the object is a list, only the brightness is displayed differently or underlined. If the object is an icon, it displays only a different color or displays a pointer. Of course, objects can be highlighted and displayed in various other ways.

The display unit 20 displays information stored in the storage unit 10 as at least one object, as well as various function menus executed in the portable terminal 100. The display unit 20 displays the highlighted object by the touch device under the control of the control unit 40. As the display unit 20, an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diodes), a touch screen, or the like can be used. At this time, the touch screen includes a display panel for displaying an image (object), and a touch panel installed on the display panel for sensing a touch. The touch screen serves both as a display device and as an input device. In this embodiment, an example using a touch screen as the display unit 20 is disclosed.

The sensing unit 30 monitors whether or not the touch device is close to the screen of the display unit 20. When the touch unit approaches the screen of the display unit 20, the sensing unit 30 outputs a sensing signal to the control unit 40. [ That is, the sensing unit 30 monitors whether or not the touch mechanism is close to the screen and moves the touch mechanism in a state close to the screen, and transmits a sensing signal to the controller 40. That is, the sensing unit 30 monitors whether or not the touch mechanism moves to the inside or outside of the critical distance with respect to the screen. The sensing unit 30 transmits a first sensing signal to the control unit 40 for highlighting and displaying the object. The sensing unit 30 transmits a second sensing signal for terminating the highlight display of the object to the control unit 40. [ The critical distance may be a vertical critical distance to the screen.

In addition, the sensing unit 30 monitors whether or not the touch mechanism moves from the inside of the vertical critical distance to the screen, but moves out of the horizontal critical distance about the highlighted object. When the touch mechanism is positioned within the horizontal critical distance, the sensing unit 30 does not transmit a separate sensing signal to the controller 40, and the controller 40 maintains the highlight display state of the object to which the touch mechanism is adjacent. When the touch mechanism moves to the outside of the horizontal critical distance, the controller 40 terminates the highlight display of the object highlighted before movement, and transmits the third detection signal for displaying the highlight of the object in proximity to the touch mechanism to the controller 40 send. At this time, the control unit 40 displays the object which has finished the highlight display as a state before highlighting.

The sensing unit 30 monitors the proximity of the touch mechanism and transmits to the controller 40 a sensing signal including position information necessary for calculating the position of the touch mechanism on the screen. For example, the sensing unit 30 may include at least one of a camera, an infrared sensor, a proximity sensor, a capacitance sensor, a radio frequency (RF) sensor, and an ultrasonic sensor. The sensing unit 30 may be provided adjacent to the display unit 20 or may be installed on the screen of the display unit 20 in the form of a film so as to monitor proximity of the touch mechanism.

In this embodiment, the display unit 20 and the sensing unit 30 are separately provided. However, the present invention is not limited thereto. That is, the display unit 20 may include the sensing unit 30. [ For example, when the touch screen is used as the display unit 20, the touch panel of the touch screen may perform the function of the sensing unit 20 together. As the touch panel, it is preferable to use a capacitive type or an infrared type touch panel capable of sensing proximity or touch of a touch mechanism.

The control unit 40 is a microprocessor that performs overall control operations of the portable terminal 100. The control unit 40 controls the highlighting process of the object to which the touch mechanism is adjacent. That is, upon receiving the first sensing signal through the sensing unit 30, the controller 40 calculates the position of the touch device on the screen based on the first sensing signal. The control unit 40 selects an object mapped to the calculated position among at least one object, and displays the highlighted object. The highlight of the selected object means that the object is underlined or at least one of the size, shape, color, and brightness of the object is transformed and displayed. Alternatively, the control unit 40 may display a pointer to the selected object, or may further display a pointer in addition to the transformation of the object. Pointers can be displayed on or near the object. In particular, when a pointer is displayed in the vicinity of the object, it can be displayed in the upper screen area with respect to the end of the touch mechanism so that the user can check the pointer.

At this time, the controller 40 may calculate the position of the touch device on the screen by using a camera vision method, an infrared method, a capacitance method, an ultrasonic method, or a combination thereof depending on the type of the sensing part 30, But is not limited thereto. For example, the camera vision method is a method of calculating the position of the touch device on the screen by analyzing and predicting the movement path of the touch device in the image captured by the camera. That is, the control unit 40 receives the image captured through the camera and extracts the touch mechanism from the received image. The control unit 40 analyzes and predicts the movement path of the end of the extracted touch mechanism to calculate the position of the touch mechanism on the screen.

The infrared method (or ultrasonic method) is a method of calculating the position on the screen of the touch mechanism which cuts off the path of infrared rays (ultrasonic waves) in a state of irradiating infrared rays (ultrasonic waves) horizontally in the X and Y directions on the screen. That is, when the progress of the infrared ray is blocked at a specific point on the screen by the touch mechanism in the state where the infrared ray (ultrasonic wave) is illuminated horizontally on the screen, the sensing unit 30 senses the sensing signal To the control unit (40). The control unit 40 calculates the position on the screen corresponding to the point where the infrared rays included in the received sensing signal are blocked.

The electrostatic capacity method is a method of calculating the position of the touch device on the screen by sensing a change in capacitance caused by a position on the screen adjacent to the touch device. That is, when the touch mechanism approaches the screen, the sensing unit 30 of the capacitance type sensing unit 30 outputs a sensing signal including positional information about a point where the touch mechanism is close to the change of the capacitance, (40). The control unit 40 calculates the position on the screen corresponding to the point where the change in the capacitance occurs.

The control unit 40 monitors whether or not the touch mechanism is within a critical distance on the screen through the sensing unit 30. For example, the control unit 40 monitors whether or not the touch mechanism moves within the vertical critical distance on the screen through the sensing unit 30. [ Upon receiving the first sensing signal for the touch mechanism moved within the vertical critical distance from the sensing unit 30, the position of the touch mechanism on the screen is calculated based on the first sensing signal. At this time, the controller 40 may calculate the position of the touch device on the screen based on the position information of the touch device included in the first sensing signal.

On the other hand, after the touch mechanism highlights the adjacent object, the control unit 40 can perform highlight processing for the object according to the movement of the touch mechanism as follows. At this time, the movement of the touch mechanism around the highlighted specific object can be represented by a combination of the vertical movement component and the horizontal movement component. The controller 40 performs highlight processing according to the vertical movement or the relationship between the horizontal movement distance and the critical distance do.

First, when the touch mechanism is moved away from the screen but outside the critical distance, the control unit 40 ends the highlight display for the object. That is, the control unit 40 monitors whether the touch mechanism moves out of the vertical critical distance on the screen through the sensing unit 30. [ Upon receiving the second sensing signal for the touch mechanism that has moved out of the vertical critical distance from the monitoring unit 30, the controller 40 ends the highlight display for the first object. The control unit 40 displays the first object on the screen before the highlight processing.

Next, when the touch device moves in the horizontal direction in the state of being close to the screen and moves out of the horizontal critical distance around the highlighted object, the control unit 40 displays highlight for the highlighted object And displays another object (hereinafter, referred to as a 'second object') highlighted and positioned at a point where the current touch mechanism is located. That is, the control unit 40 monitors whether the touch device moves out of the horizontal critical distance at the position of the first object through the sensing unit 30. Upon receiving the third sensing signal for the touch mechanism that has moved out of the horizontal critical distance from the monitoring unit 30, the control unit 40 ends the highlight display for the first object. The control unit 40 calculates the position of the touch device on the screen based on the third sensing signal. Then, the controller 40 selects a second object mapped to the calculated position among at least one object, and displays the highlighted second object. When the touch device is moved in the horizontal direction on the screen in the state of being close to the screen, the controller 40 can sequentially perform highlighting and highlighting of the object on the movement path of the touch device along the moving direction. The movement in the horizontal direction means that the touch mechanism moves within the vertical critical distance, and the movement is referred to as horizontal movement because the horizontal component is dominant as compared with the vertical component. Even if the touch mechanism moves in the horizontal direction, the control unit 40 performs the highlight processing according to the vertical threshold distance without performing the highlight processing according to the movement of the touch mechanism in the horizontal direction.

On the other hand, if the touch device is out of the screen while a specific object is highlighted, the control unit 40 may terminate the highlight display for the object.

Here, the vertical critical distance may be set to a predetermined distance in the vertical direction with respect to the screen. The horizontal threshold distance may be set to a predetermined distance in the horizontal direction around the object, and is preferably set within a range that does not overlap neighboring objects. While the vertical and horizontal threshold distances are set to default and may be reset by the user.

On the other hand, since the object with the touch mechanism is highlighted and displayed, the user can easily confirm whether or not the object is the target object through the highlighted object. If the highlighted object is not the target object, the user can change the highlight location by moving the touch target to the target object. When the user touches the object with the touch mechanism in a state where the target object is highlighted, the display unit 20 transmits the touch information of the object to the control unit 40. The control unit 40 performs a function mapped to the object based on the received touch information.

As described above, the portable terminal 100 according to the embodiment of the present invention guides the user to select a target object precisely because the object is highlighted and displayed when the touch mechanism approaches a specific object on the screen. Accordingly, the mobile terminal 100 according to the present embodiment can minimize an error in touching an object other than a target object by a user.

A method of displaying an object of a portable terminal according to an embodiment of the present invention will now be described with reference to FIGS. 1 and 2. FIG. 2 is a flowchart illustrating an object display method of a mobile terminal according to an exemplary embodiment of the present invention. Here, an example in which a touch screen is used as the display unit 20 is disclosed.

First, in step S51, the mobile terminal 100 displays at least one object on the screen of the display unit 20. At this time, when the user's selection signal is input through the display unit 20, the portable terminal 100 can display at least one object on the screen. Or when the user presses a specific key provided in the portable terminal 100, the portable terminal 100 can display at least one object on the screen.

Next, in step S53, the portable terminal 100 monitors whether or not the touch mechanism approaches the screen through the sensing unit 30. That is, the portable terminal 100 monitors whether or not the tactile tool moves through the sensing unit 30 to a critical distance, for example, within a vertical critical distance. At this time, the sensing unit 30 may periodically monitor or continuously monitor whether the touch mechanism is in proximity.

If the monitoring result of step S53 is that the touch device is not close to the screen within the vertical critical distance, the portable terminal 100 maintains the display state of step S51.

If the monitoring result of step S53 is that the touch device is close to the screen within the vertical critical distance, the portable terminal 100 calculates the position on the screen of the touch device in step S55. That is, when the sensing unit 30 senses a touch mechanism that is close to the screen within a vertical critical distance, it transmits a first sensing signal to the controller 40. [ The portable terminal 100 calculates the position of the touch device on the screen based on the first sensing signal. At this time, the mobile terminal 100 may calculate the position of the touch device on the screen based on the position information of the touch device included in the first sensing signal. For example, the position of the finger or touch mechanism on the screen of the portable terminal 100 can be calculated using at least one of a capacitive method, an infrared method, an ultrasonic method, and a camera vision method.

Next, in step S57, the mobile terminal 100 selects an object mapped to the calculated position among at least one object. Subsequently, in step S59, the portable terminal 100 highlights and displays the selected object. That is, the portable terminal 100 may highlight an object selected by displaying an underline on the selected object or modifying at least one of the size, shape, color, and brightness of the selected object. Alternatively, the portable terminal 100 may display a pointer to the selected object, or may further display a pointer in addition to the highlight display.

In step S61, the portable terminal 100 monitors whether or not there is movement of the touch mechanism after highlighting the object through the sensing unit 30. [ That is, the portable terminal 100 monitors whether or not the touch mechanism moves out of the critical distance with respect to the screen through the sensing unit 30. For example, the portable terminal 100 monitors whether or not the touch device is out of a vertical or horizontal critical distance around the highlighted object through the sensing unit 30.

If the movement of the touch mechanism is not detected in step S61, the portable terminal 100 maintains the display state of step S59.

If it is determined in step S61 that the movement of the touch mechanism is detected, the mobile terminal 100 determines whether or not the movement is out of the vertical critical distance in step S63.

If it is determined in step S63 that the mobile terminal 100 is not moving out of the vertical threshold distance, the mobile terminal 100 determines again whether or not the movement is out of the horizontal threshold distance in step S65. That is, the portable terminal 100 determines whether or not the movement generated when the touch mechanism is close to the screen is out of the horizontal critical distance.

As a result of the determination in step S65, if the mobile terminal 100 does not move out of the horizontal threshold distance, the mobile terminal 100 maintains the displayed state in step S59. If the movement of the touch mechanism does not deviate from the vertical or horizontal critical distance, the portable terminal 100 maintains the display state of step S59.

If it is determined in step S65 that movement outside the horizontal threshold distance is detected, the mobile terminal 100 ends the highlighting of the highlighted object in step S67. Subsequently, the portable terminal 100 can perform the process from step S55 again to highlight another object close to the position where the touch mechanism has moved. That is, when the user moves the touch device in the horizontal direction on the screen in the state of being close to the screen, the portable terminal 100 can sequentially perform the highlighting and the highlighting of the object on the movement path of the touch device along the moving direction .

The user can visually confirm whether the object highlighted on the screen is a target object. If the highlighted object is a target object, the user can touch the touch object to perform a function mapped to the object. That is, when the target object is highlighted, when the user touches the corresponding object with the touch mechanism, the display unit 20 transmits the touch information of the object to the control unit 40. The control unit 40 performs a function mapped to the object based on the received touch information.

If it is determined in step S63 that movement outside the vertical threshold distance is detected, the mobile terminal 100 ends the highlighting of the highlighted object in step S71.

On the other hand, if it is determined in step S61 that the movement of the touch device is detected and the touch device moves out of the screen area, the portable terminal 100 may terminate the highlight of the highlighted object.

A method of displaying an object of a portable terminal according to an embodiment of the present invention will now be described with reference to an exemplary diagram of FIG. 3 shows an example in which a plurality of menus 23 arranged in a lattice arrangement on the screen are displayed as objects. At this time, although the touch mechanism 80 is shown as "+" for convenience of illustration in Fig. 3, "+" is not actually displayed on the screen.

3 (a), in a state where a plurality of menus 23 are displayed on the screen 21 of the display unit 20, as shown in Fig. 3 (b), a plurality of menus 23 The portable terminal 100 highlights and displays the "E menu " as shown in Fig. 3 (c) by bringing the touch mechanism 80 close to the menu, e.g., the" E menu ". 3C, the portable terminal 100 displays an example in which the color of the "E menu" is displayed in a different color from that of the other menus. However, the present invention is not limited thereto. For example, the portable terminal 100 may underline a menu or display at least one of the size, shape, color, and brightness of the menu (object) by modifying the menu.

Next, as shown in Fig. 3 (d), when the user moves the touch mechanism 80 in the horizontal direction in the state of being close to the screen and places it in the "H menu", the portable terminal 100 displays "E Menu "is highlighted and the" H menu "is highlighted. At this time, in order to display the moving state of the touch mechanism 80, the portable terminal 100 displays a pointer at a position corresponding to the position on the screen of the touch mechanism 80 in Figs. 3B and 3D can do.

3 (c) or 3 (d), when the user moves the touch mechanism 80 out of the vertical critical distance, the portable terminal 100 displays the highlighted menu The display of the highlight of FIG. That is, the portable terminal 100 displays the menu 23 in a state before highlighting.
