2 is a flowchart illustrating a process for providing a screen magnification function in an electronic device according to an exemplary embodiment of the present disclosure.

Referring to FIG. 2, in operation 201, the electronic device operates a sensing unit capable of detecting a proximity touch. Here, the proximity touch is located at a distance (proximate touch area) at which the touch input means (for example, a finger, an electronic pen, a stylus pen, etc.) can be judged to have contacted on the touch screen, and thus the actual touch screen input is generated. State before. In addition, the input contacted by the touch input means on the touch screen may be referred to as direct input.

In this case, according to an exemplary embodiment of the present disclosure, the electronic device may include a proximity sensor that detects a proximity touch on a portion of the touch screen.

In addition, according to another preferred embodiment of the present invention, the electronic device may include a space touch panel capable of detecting a touch input means in a space to sense a proximity touch.

Of course, the electronic device according to the present invention may detect the proximity touch by using the above-mentioned method in combination.

In operation 203, the electronic device operating the sensing unit capable of detecting the proximity touch checks whether the proximity touch is detected.

If the proximity touch is not detected in step 203, the electronic device repeats the process of step 201.

In operation 203, if the proximity touch is detected, the electronic device proceeds to step 205 to identify the point where the proximity touch is detected, and proceeds to step 207 to enlarge and output the identified point.

In this case, the electronic device may enlarge the screen of the predetermined area around the point detected by the sensing unit. In addition, the electronic device may enlarge only some objects (eg, icons, text, etc.) corresponding to the points detected by the sensing unit.

In operation 209, the electronic device determines whether the proximity touch with respect to the touch input means is released. Here, the release of the proximity touch may be a situation in which the touch input means leaves the proximity touch area. In this case, the situation in which the touch input means performs the direct touch may also be regarded as being out of the proximity touch area, but the direct touch in the present invention is excluded from the proximity touch release.

If it is detected in step 209 that the proximity touch release to the touch input means is detected, the electronic device proceeds to step 211 to process to restore the enlarged screen to the original screen.

In operation 209, when the proximity touch release of the touch input means is not detected, the electronic device proceeds to step 213 and determines whether the touch input is directly detected by the touch input means. Herein, the direct touch refers to a situation in which the touch screen is touched by a touch input means in a situation in which the output screen is enlarged by using a proximity touch.

If the direct touch is detected in step 213, the electronic device proceeds to step 215 to perform an operation on the direct touch. In this case, if an application icon exists at a point where a direct touch occurs, the electronic device may execute the corresponding application. In addition, if the object does not exist at the point where the direct touch occurs, the electronic device may output a menu (eg, a folder creation menu, etc.) for restoring the output enlarged screen or controlling an additional function for the output screen.

In addition, if the touch is not directly detected in step 213, the electronic device proceeds to step 217 to check the sensing information, and in step 219, the electronic device adjusts the magnification (magnification size) of the enlarged screen according to the sensing information. In this case, when the direct touch is not sensed, the touch input means moves in the proximity touch area, and the electronic device divides the proximity touch area into a plurality of steps and sets an enlargement magnification for each step. You can save the table.

That is, the electronic device may enlarge or reduce the output screen according to the change of the position of the touch input means in the proximity touch area.

In step 209, the electronic device that has adjusted the magnification of the magnification screen may check whether the proximity touch is released. After the restoration of the magnification screen or the operation on the direct touch is performed, the algorithm according to the present invention is terminated. do.

As described above, the electronic device for detecting the proximity touch may provide an advantage of expanding and outputting an object on the touch screen covered by the touch input means before being directly touched.

In addition, although the proximity touch of the touch input means is sensed by using the proximity touch area generated by the operation of the sensing unit in FIG. 2, the present invention can be applied to a touch screen type electronic device having no sensing unit.

For example, the capacitive touch screen that charges electrons in the glass layer of the upper end may detect the touch input according to the change of electrons generated by the contact of the touch input means having conductivity. In this case, the electronic device having the capacitive touch screen determines whether a touch input is generated by using a change in electrons above the threshold value, and the amount of electronic change that changes as the touch input means contacts the touch screen is greater than or equal to the threshold value. Becomes

However, even when the touch input means is in close proximity without being touched on the touch screen, a change in the former may be sensed, and the present invention may be applied using this fact.

That is, an electronic device having a capacitive touch screen defines an enlarged magnification by dividing the electronic change until the touch input means is touched step by step, and when the touch input means approaches the touch screen, Some objects can be enlarged and printed.

3 is a diagram for describing a touch input detected by an electronic device according to an exemplary embodiment of the present disclosure.

Referring to FIG. 3, the touch input may include a proximity touch, a direct touch, and a proximity touch release as described above, and the above touch input may be divided based on the touch screen and the proximity touch area.

The proximity touch area is an area capable of detecting touch input means (for example, a finger, an electronic pen, a stylus pen, etc.) in a non-contact state on the touch screen. For example, a sensing area formed by the operation of a proximity sensor, a sound wave sensor The sensor may be a sensing area formed by an operation such as a space sensor.

The proximity touch is an input of the number of touch inputs performed in the proximity touch area, and is distinguished from a touch input touching an actual touch screen. For this reason, the proximity touch release refers to an input in which the touch input means is moved out of the proximity touch area.

In addition, the direct touch refers to an input of directly touching the touch screen by a touch input means.

Reference numeral (a) is a diagram for explaining the proximity touch region, and the region 302 in the threshold 301 may be the proximity touch region based on the touch screen 300. In this case, the threshold 301 may be determined by the performance of the sensing unit included in the electronic device. That is, when the electronic device uses the proximity sensor, the electronic device may be a sensing area of the proximity sensor. In addition, when the electronic device includes a touch screen composed of a space sensor and a sound wave sensor, the electronic device may be a space generated according to the operation of the touch screen.

In addition, the proximity touch area may be formed by a touch screen that detects an electronic change amount according to the approach of the touch input means.

In addition, the proximity touch region may also be formed by the touch input means. That is, the touch input means for generating information (eg, sound wave, resonant frequency, etc.) for detecting the touch input, for example, the proximity touch area may be an area for detecting the information of the touch input means on the touch screen. have.

Reference numeral (b) is a diagram illustrating a proximity touch. When the electronic device senses a touch input means 310 in a proximity touch area (the area within the threshold 301), it is determined that a proximity touch has occurred. can do. In this case, the proximity touch means that the touch input means is located within the touch screen 300 and the threshold 301. When the touch input means contacts the touch screen, the proximity touch is directly touched.

Reference numeral (c) is a diagram for explaining a proximity touch release. When the electronic device senses the touch input means outside the proximity touch area (the area within the threshold 301) (320), the proximity touch is released. Can be judged.

Reference numeral (d) is a diagram for explaining a direct touch, and the electronic device may determine that a direct touch has occurred when the touch input means contacts the touch screen 330.

4 is a diagram illustrating a process of enlarging a screen using a proximity touch in an electronic device according to an exemplary embodiment of the present disclosure.

Referring to FIG. 4, as described above, the electronic device may detect a proximity touch on the touch input means. This is to sense the touch input means in the proximity touch area, which is an area between the touch screen and the threshold value, and the threshold value is a reference value used to determine whether or not the proximity touch.

That is, when the user's finger is positioned 410 in the proximity touch area between the touch screen 400 and the threshold 401 as shown by reference numeral (a), the electronic device may not be connected to the touch screen of the user. Likewise, a touch input of a corresponding position can be detected.

Reference numerals (b) to (c) illustrate a process of enlarging the output screen in the electronic device according to the present invention.

That is, reference numeral b denotes that the user of the electronic device performs the proximity touch, and the user's finger is not in contact with the touch screen like the reference numeral a.

At this time, some of the icons are covered by the user's finger and thus not recognized. Accordingly, the electronic device according to the present invention may enlarge and output the object 403 at the position where the proximity touch occurs as shown by reference numeral (c). The object enlarged and output by the reference sign (c) is an object covered by the proximity touch in the reference sign (b).

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
