Therefore, rubbing recognition is being studied to increase the resolution of the gesture. However, the input of the rubbing shows a white noise characteristic and varies greatly depending on the input environment such as temperature and humidity, the input method of the user (for example, rubbing speed, rubbing strength).

Therefore, it is difficult to extract general features in the frequency and time domain only by surface treatment of the pad receiving the input.

According to an aspect of the present invention, a signal disconnection structure is applied to a pad for inputting a user's gesture, so that a signal disconnection pattern is displayed in a rubbing signal, thereby recognizing a user's rubbing direction.

These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements.

1 is a block diagram illustrating a user input device in accordance with an embodiment of the present invention.

Referring to FIG. 1, the user input device 10 may include a pad 100, a sensing unit 200, and an analysis unit 300.

The pad 100 may include a first pad portion and a second pad portion. However, this is for convenience of explanation, and the pad 100 may further include an additional pad portion to divide the direction of the user's rubbing input or to express the rubbing input characteristic.

As will be described in more detail with reference to FIGS. 2 and 3, the sensing unit 200 is attached to the first pad unit to detect user input. The second pad portion is spaced apart from the first pad portion so that the user input passing through the second pad portion is not sensed by the sensing portion 200.

The pad 100 has a shape in which the first pad portion and the second pad portion are alternately arranged in one direction. When the user rubs the pad 100 in one direction, an input signal is sensed when rubbing over the first pad, but no input signal is sensed when rubbing over the second pad. Accordingly, the user's rubbing input can be detected as a signal disconnection pattern.

The sensing unit 200 may be attached to the inside or the outside of the first sensing unit through an adhesive, a housing, or a special structure. The sensing unit 200 may include a sound wave measuring sensor such as a microphone or a vibration measuring sensor.

The analysis unit 300 may analyze the signal disconnection pattern by converting the analog signal detected by the sensing unit 200 into a digital signal. According to the embodiment, the analyzing unit 300 stores a table for matching the direction of a specific signal disconnection pattern according to the configuration of the pad 100, and thereby can understand the meaning of the detected signal disconnection pattern.

According to the embodiment. The user input device 10 may further include a control unit 400. The control unit 400 can control other electronic devices based on the user input analyzed by the analysis unit 300.

According to an embodiment, the user input device 10 according to an embodiment of the present invention can be mounted inside a vehicle, and thus the control unit 400 can control other devices in the vehicle.

Referring to FIG. 1, the sensing unit 200 is attached to the first pad unit, and the user input through the second pad unit is not sensed. However, the sensing unit 200 may be attached to the second pad unit And the user input passing through the first pad unit is not sensed.

2 is a top view and a cross-sectional view of a pad included in a user input device according to an embodiment of the present invention.

Referring to FIG. 2, the pad 100 may include a first pad portion 110 and a second pad portion 120. As described above, the first pad portion 110 and the second pad portion 120 may be alternately arranged in the first direction.

The sensing unit 200 may be attached to the first pad unit 110 to sense a user input on the first pad unit 110. However, since the second pad unit 120 is spaced apart from the first pad unit 110, the signal input to the sensing unit 200 is cut off when the user's input passes the second pad unit 120.

According to the embodiment, the first pad portion 110 is configured to surround the second pad portion 120, so that when the user rubs the pad 100 in the longitudinal direction, However, a signal disconnection pattern can be generated in such a manner that the inputs therebetween are disconnected.

Accordingly, the second pad portion 120 may be arranged in the form of an island in the first pad portion 110.

2, the first pad portion 110 may correspond to the upper pad, and the second pad portion 120 may be formed in an island shape in the first pad portion 110 by coupling the mount pad to the base. .

The pad 100 included in the user input device 10 according to an embodiment of the present invention may form various signal disconnection patterns while differently arranging the second pad portion 120 in one direction. By having the signal disconnection pattern, the direction in which the user rubs can be clearly determined by recognizing the signal disconnection pattern irrespective of the surrounding environment or the input characteristics of the user.

3 is a cross-sectional view of a pad according to another embodiment of the present invention.

Referring to FIG. 3, a first pad portion 110a and a second pad portion 120a to which the sensing portion 200 is attached are shown.

The second pad portion 120a is disposed in the first pad portion 110a in an island shape. By differently arranging the second pad portion 120a, the sensing portion 200 can recognize the direction in which the user rubs the pad. In other words, the second pad portion 120a may be disposed at a different interval with respect to one side to which the sensing portion 200 is attached.

For example, when the user rubs the pad in a direction approaching the sensing unit 200, the user input sensed by the sensing unit 200 has a pattern in which the period in which the signal is disconnected gradually decreases.

When the user rubs the pad in a direction away from the sensing unit 200, the user input sensed by the sensing unit 200 has a pattern in which the period in which the signal is disconnected becomes longer.

Such a signal disconnection pattern is easy to grasp when a signal is input or disconnected depending on the surrounding environment. Even if the user rubs the pad quickly or rubs slowly, only the relative length of the disconnection period of the input signal can be grasped, The accuracy of recognizing the user input can be improved.

As described above, the user input device 10 according to an embodiment of the present invention includes a pad unit to which the sensing unit 200 is attached and at least one other pad unit that can not transmit a signal to the sensing unit 200, And a pad 100 for alternately arranging the pad with the sensing unit 200 and another pad unit capable of giving a signal interruption to the sensing unit 200.

Because the pad 100 includes the user input device 10, the user can analyze the user's rubbing input through the signal disconnection pattern and accurately recognize the user input without being affected by the surrounding environment or the characteristics of each user .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Will be clear to those who have knowledge of.
