The fourth unit may include deleting the entire characters which are being input.

The controller 260 may control a deleted character unit according to the number of input time of touch gesture. For example, the controller 260 may control the character to be deleted by the fifth unit when the number of touch gesture input is less than a first number of time, and may control the character to be deleted by the sixth unit, which is larger than the fifth unit, when the number of touch gesture input is more than the first number of time. The sixth unit may include deleting the entire characters.

Hereinafter an operating method of the touch input device in accordance with one embodiment of the present disclosure will be described in detail.

FIGS. 9 to 12 are views illustrating an example of flicking operation of touch input device 200, and an example of an operation screen displayed on the display 240.

Referring to FIG. 9, a user may delete a character being input by inputting a flicking gesture in a first direction in the touch unit 210 by using a single finger. Herein, the first direction may represent a direction of the right side to the left side, but is not limited thereto. However, in general, a character may be input from the left side to the right side. Thus, when the first direction is a direction of the right side to the left side, the user may more intuitively input a command of deleting a character compared with when inputting a character.

A user may adjust a method of deleting a character by adjusting the number of simultaneous touch, input speed, input time, size, or the number of time of a flicking gesture input to the touch unit 210. Particularly, as illustrated in FIG. 9, when the user inputs a flicking gesture by using a single finger, a single character may be deleted. Referring to FIG. 10, when the user inputs a word, e.g., “HYUNDAI MOTEPZ” to a word display area of the display unit 240, the user may input a command of deleting “Z” by inputting a flicking gesture by using a single finger.

According to the embodiment, when inputting the flicking gesture by using a single finger repeatedly, a command of deleting “Z” and a command of deleting “P” may be input in order, and when inputting the flicking gesture by a single finger at a speed faster than the previous speed, a character may be deleted in a direction of from “Z” to “P” with certain acceleration.

According to the embodiment, when continuously inputting the flicking gesture at least twice, the entire characters being input may be deleted. For example, when the user continuously inputs the flicking gesture with more than three seconds, “MOTOPZ” may be deleted or “HYUNDAI MOTOPZ” may be deleted. When determining a unit of deleted character being input, whether word spacing unit is included or not may be pre-determined or may be temporarily determined by a user.

According to the embodiment, when inputting the flicking gesture with a diameter, which is less than the first diameter, a character among characters, which are being input may be deleted by a pre-determined unit, and when inputting the flicking gesture with a diameter, which is larger than the first diameter, the entire characters, which are being input, may be deleted. For example, when the user inputs the flicking gesture with a diameter, which is less than 3 cm, a command of deleting a unit of character, that is “Z” in “HYUNDAI MOTOPZ” may be input, and when a user inputs the flicking gesture with a diameter, which is larger than 3 cm, “MOTOPZ” may be deleted or “HYUNDAI MOTOPZ” may be deleted. When determining the unit of deleted character being input, whether word spacing unit is included or not may be pre-determined or may be temporarily determined by the user.

The user may adjust the number of deleted characters by using a plurality of fingers.

As illustrated in FIG. 11, when the user inputs a flicking gesture by using three fingers, three characters may be deleted. Referring to FIG. 12, when the user inputs a word, e.g., “HYUNDAI MOTOPZ” to the word display area of the display unit 240, the user may input a command of deleting “P,” “Z,” and “O” by inputting a flicking gesture by using three fingers. According to the embodiments, when the user inputs a flicking gesture by using a single finger repeatedly, a command of deleting “T” and “O” may be input. When a user inputs a flicking gesture by using a single finger, as illustrated in FIG. 9 after inputting a flicking gesture by using three fingers, as illustrated in FIG. 11, a command of deleting “T,” “O,” “P,” and “Z” in “HYUNDAI MOTOPZ” may be input.

As the same method, when the user inputs a flicking gesture by using two fingers, a command of deleting two characters may be input. When the user inputs the flicking gesture by using four fingers, a command of deleting four characters may be input. When the user inputs the flicking gesture by using five fingers, a command of deleting five characters may be input. According to the embodiment, when the flicking gesture is input to the touch unit 210 by three and more fingers, the entire characters may be deleted. For example, in a state in which “HYUNDAI MOTOPZ” is being input, when the flicking gesture is input to the touch unit 210 by three to five fingers, “MOTOPZ” may be deleted or “HYUNDAI MOTOPZ” may be deleted. When determining the unit of deleted character being input, whether a word spacing unit is included or not may be pre-determined or may be temporarily determined by the user.

FIG. 13 is a view illustrating an example of swiping operation of touch input device 200, and FIG. 14 is a view illustrating an operation screen displayed on a display according to the swiping gesture of FIG. 13.

Referring to FIGS. 13 and 14, a user may delete a character, which is being input, by inputting a swiping gesture to the touch unit 210 as erasing in a blackboard. The user may delete a character being input by inputting a gesture performed by swiping the touch unit 210 horizontally.

A user may adjust a method of deleting character by adjusting the number of simultaneous touch, input speed, input time, size, or the number of time of a swiping gesture input to the touch unit 210.

For example, in a state of inputting “HYUNDAI MOTOPZ”, when the user inputs the swiping gesture by a single finger, as illustrated in FIG. 13, a command of deleting “Z” may be input, as illustrated in FIG. 14. According to the embodiment, when the swiping gesture is input by two fingers, the command of deleting “Z” and the command of deleting “P” may be simultaneously input.

When the swiping gesture is repeatedly input by the single finger, the command of deleting “Z” and the command of deleting “P” may be input in order. When the swiping gesture is input by the single finger at a faster speed than the previous speed, a character may be deleted in a direction of from “Z” to “P” with a certain acceleration.

When the swiping gesture is input continuously at least twice, the entire characters being input may be deleted. For example, when the user continuously inputs the swiping gesture with more than three seconds, “MOTOPZ” may be deleted or “HYUNDAI MOTOPZ” may be deleted. When determining the unit of deleted character being input, whether the word spacing unit is included or not may be pre-determined or may be temporarily determined by the user.

According to the embodiment, when the swiping gesture is input with a diameter, which is less than the previous diameter, a character among inputted characters may be deleted by a pre-determined unit. When the swiping gesture is input with a diameter, which is larger than the previous diameter, the entire inputted characters may be deleted. For example, when the user inputs the swiping gesture with a diameter, which is less than 3 cm, the command of deleting a unit of character, that is “Z” in “HYUNDAI MOTOPZ” may be input. When the user inputs the swiping gesture with a diameter, which is larger than 3 cm, “MOTOPZ” may be deleted or “HYUNDAI MOTOPZ” may be deleted. When determining the unit of deleted character being input, whether the word spacing unit is included or not may be pre-determined or may be temporarily determined by the user.

Hereinafter, a control method of the input device according to one embodiment will be described.

A control method of the input device 200 in accordance with one embodiment may include receiving an input of a command of touch via the touch unit 210, determining a unit of deleted character, which is being input, based on the number of simultaneous touch of touch gesture input to the touch unit 210. The touch gesture may include at least one gesture for deleting character, which is selected from the group including the above mentioned flicking, rolling, spinning, swiping, or tapping, but is not limited thereto.

The step of determining the unit of deleted character based on the number of simultaneous touch of touch gesture input to the touch unit 210 may include determining two characters to be deleted when a touch gesture including a single touch is input and determining two and more characters to be deleted or the entire characters to be deleted when a touch gesture including a plurality of pre-determined simultaneous touches are input.

According to the embodiment, the control method may include deleting a character at a first speed when a touch gesture input speed is less than a second speed. Further, the method includes deleting the character at a third speed, which is faster than the first speed, when the touch gesture input speed is faster than the second speed. According to the embodiment, when the touch gesture input speed is faster than the second speed, the character may be deleted with a certain acceleration.

The control method of the input device 200 may include deleting the character by a first unit when the touch gesture is input with a first time. The method further includes deleting a character by a second unit, which is larger than the first unit, when the touch gesture input time is longer than the first time. Here, the deleting by the second unit may include deleting the entire characters.

The control method may include deleting the character by a third unit, when a touch gesture a diameter is less than a first diameter. The method further includes deleting a character by a fourth unit, which is larger than the third unit, when the touch gesture diameter is large than the first diameter. The deleting by the fourth unit may include deleting the entire characters.

The control method may include deleting the character by a fifth unit when the number of touch gesture input is less than a first number of time. The method further includes deleting a character by a sixth unit, which is larger than the fifth unit, when the number of touch gesture input is more than the first number of time. The deleting by the sixth unit may include deleting the entire characters.
