이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 휴대용 단말기의 구성도이고, 도 2는 본 발명의 실시예에 따른 휴대용 단말기의 햅틱 제어방법에 대한 흐름도이며, 도 3은 본 발명의 다른 실시예에 따른 휴대용 단말기의 햅틱제어방법에 대한 흐름도이다.1 is a block diagram of a portable terminal according to an embodiment of the present invention, Figure 2 is a flow chart for a haptic control method of a portable terminal according to an embodiment of the present invention, Figure 3 is a portable according to another embodiment of the present invention It is a flowchart of the haptic control method of a terminal.

도 1에 도시된 바와 같이, 본 발명의 실시예에 따른 휴대용 단말기는 사용자로부터 명령이나 정보를 입력받는 터치스크린(20)과, 진동을 발생시키는 진동모 터(30)와, 터치스크린(20)의 입력신호에 따라 진동모터(30)를 제어하는 제어부(10)로 구성된다.As shown in FIG. 1, a portable terminal according to an embodiment of the present invention includes a touch screen 20 for receiving a command or information from a user, a vibration motor 30 for generating a vibration, and a touch screen 20. The control unit 10 for controlling the vibration motor 30 in accordance with the input signal of the.

터치스크린(20)은 인터페이스로서 어플리케이션을 구현하거나 각종 데이터의 입력을 받는 역할을 한다.The touch screen 20 implements an application as an interface or serves to receive various data.

진동모터(30)는 진동주파수에 대응하여 진동을 발생시키는 것으로 터치스크린(20)의 각 모서리에 위치한다. 이때, 진동모터(30)는 터치스크린의 중심에서 각 서로 대응하는 위치에 복수개가 설치되는 것이 바람직하다. The vibration motor 30 generates vibration in response to the vibration frequency and is located at each corner of the touch screen 20. At this time, it is preferable that a plurality of vibration motors 30 are installed at positions corresponding to each other in the center of the touch screen.

제어부(10)는 터치스크린(20)에 입력된 좌표값을 수신받아 각 진동모터(30)로부터의 거리를 연산하고, 각 연산된 거리에 반비례하도록 진동주파수를 설정하여 이에 대응하게 진동모터(30)를 구동시킨다. The control unit 10 receives the coordinate values input to the touch screen 20, calculates the distance from each vibration motor 30, sets the vibration frequency in inverse proportion to each calculated distance, and correspondingly corresponds to the vibration motor 30. ).

또한, 제어부(10)는 터치후 특정방향으로 연속적으로 이동할 때, 이동속도를 연산하고, 연산된 이동속도 값에 비례하여 진동과 휴지기가 구현되도록 교대주파수를 설정한다.In addition, the controller 10 calculates the moving speed when continuously moving in a specific direction after the touch, and sets the alternating frequency so as to implement vibration and rest in proportion to the calculated moving speed value.

예를 들면, 터치후 이동속도가 빠르면 제어부(10)는 이동속도값에 대응하도록 교대주파수를 빠르게 설정한다. 그러면 액취에이터(30)는 교대주파수에 대응하게 진동과 휴지기를 빠르게 발생시키게 된다. 즉, 사용자는 터치후 이동속도에 따라 다른 진동주기를 느낄 수 있다.For example, if the moving speed is high after the touch, the controller 10 quickly sets an alternate frequency to correspond to the moving speed value. The actuator 30 then quickly generates vibrations and pauses corresponding to the alternating frequency. That is, the user may feel different vibration cycles according to the moving speed after the touch.

도 2에 도시된 바와 같이, 본 발명의 실시예에 따른 휴대용 단말기의 햅틱제어방법은 우선, 사용자로부터 터치입력 받는 것으로 시작된다(S100).As shown in FIG. 2, the haptic control method of a portable terminal according to an embodiment of the present invention first begins with receiving a touch input from a user (S100).

터치 입력후 제어부(10)는 터치된 위치의 좌표를 수신받는다(S110). 그리고, 제어부(10)는 각 진동모터로부터 좌표의 위치까지 각각 거리를 연산한다(S120).After the touch input, the controller 10 receives the coordinates of the touched position (S110). Then, the control unit 10 calculates the distance from each vibration motor to the position of the coordinates (S120).

이후 제어부(10)는 연산된 거리에 반비례하도록 진동주파수를 설정한다(S130). 그러면 제어부(10)는 진동주파수에 대응하는 진동세기가 발생하도록 진동모터를 구동시킨다(S140).Thereafter, the controller 10 sets the vibration frequency to be inversely proportional to the calculated distance (S130). Then, the control unit 10 drives the vibration motor to generate a vibration intensity corresponding to the vibration frequency (S140).

도 3에 도시된 바와 같이, 본 발명의 다른 실시예에 따른 휴대용 단말기의 햅틱제어방법은 사용자로부터 터치입력을 받고, 터치된 위치의 좌표를 수신받아 각각의 진동모터로부터 좌표의 위치까지 각각 거리를 연산한다(S200,S210,S220).As shown in FIG. 3, the haptic control method of a portable terminal according to another embodiment of the present invention receives a touch input from a user, receives coordinates of a touched position, and receives a distance from each vibration motor to a coordinate position, respectively. Compute (S200, S210, S220).

이때, 제어부(10)는 연산된 거리를 미리 구간에 따라 단계별 설정된 값과 비교하여 해당하는 값에 반비례하도록 진동주파수를 설정한다(S230,S240). At this time, the control unit 10 sets the vibration frequency to be inversely proportional to the corresponding value by comparing the calculated distance with the step-by-step set value in advance according to the section (S230, S240).

여기서, 설정된 값은 임의 설정될 수 있는 값으로, 예를 들면 진동모터로부터 좌표까지 연산된 거리가 1에서 3까지 사이의 거리안에 포함되면 거리를 2라는 값으로 임의 설정할 수 있다. 따라서, 제어부는 2라는 거리의 반비례하도록 진동주파수를 설정하면 된다.Here, the set value is a value that can be arbitrarily set. For example, if the distance calculated from the vibration motor to the coordinates is included in the distance between 1 and 3, the distance can be arbitrarily set to 2. Therefore, the control unit may set the vibration frequency to be inversely proportional to the distance of two.

그리고, 제어부(10)는 단계별 설정된 진동주파수에 대응하는 진동세기가 발생하도록 진동모터(30)를 구동시킨다(S250). Then, the controller 10 drives the vibration motor 30 to generate a vibration intensity corresponding to the set vibration frequency step by step (S250).

이와 같이, 본 발명은 터치스크린의 위치에 따라 다른 진동의 세기로 전달하여 사용자에게 보다 생동감을 줄 수 있다.In this way, the present invention can be delivered to the user by vibrating different intensity of vibration according to the position of the touch screen.
