Hereinafter, a method of controlling the dialing haptic device 5 of the present invention will be described with reference to FIGS. 11 to 15. 11 shows a flowchart of the control process of the dialing haptic device 5 of the present invention, and FIGS. 12 to 15 show a schematic flowchart of each of the detailed steps. The control of the dialing haptic device according to the present invention is shown. The method includes providing a dialing haptic device (S100), a dialing input step (S200), and a terminal number output step (S300). In the providing step S100, the above-described dialing haptic device 5 is provided, and the description of the dialing haptic device 5 is replaced by the above. After the dialing haptic device 5 is provided in the providing step S100, a dialing input step S200 of determining a predetermined dialing number from a signal input to the dialing haptic switch unit 10 by a user is performed.

FIG. 12 is a schematic flowchart of the dialing input step S200, and FIGS. 13 to 15 are detailed flowcharts of each detailed step of the dialing input step S200. The dialing input step S200 includes a signal input step S210, a signal determination step S220, and a signal determination step S230, which are newly established through the dialing haptic switch unit 10 in the signal input step S210. It is determined whether or not the dialing signal input by the user based on the signal input through the dialing haptic switch unit 10 in the signal determination step (S220), and outputs the terminal from the dialing signal in the signal determination step (S230) It is determined whether dialing signal output data for transmission to the unit 85 is formed.

In more detail, the signal input step S210 may include an input sensing step S2110, an input normal determination step S2120, and an input haptic performing step S2130. First, the haptic rotary switch detection unit is performed in the input sensing step S2110. 400 detects the rotation input through the haptic rotary switch knob. That is, when a rotational force is generated through the haptic rotary switch knob by the user, the haptic rotary sensor 400 generates a detection signal by the rotation of the haptic rotary switch knob and transmits it to the controller 60. Here, although omitted in the redundant description, the control unit 60 that receives a signal detected through the haptic rotary sensor 400 in real time is a preset operation mode (see FIGS. 8 and 9) of the detected signal and the storage unit. By transmitting a predetermined signal corresponding to the haptic rotary switch driver 310 to operate the haptic rotary switch driver 310 may provide a user with a predetermined sense of detent.

Thereafter, the control unit 60 performs an input normal determination step S2120 for determining whether the detection signal obtained in the input detection step S2110 is a normal input state, which is generated and transmitted through the haptic rotary switch detection unit 400. Determine whether the detection signal is error. For example, if the user rotates the haptic rotary switch knob at an excessively high speed or excessively sudden left and right rotation occurs so that a predetermined time necessary for the operation of the haptic rotary switch drive is not provided, the haptic rotary switch is detected. The control unit (or a separate calculation unit) processes the detection signal obtained through the unit, and when it is determined that the storage unit has a value greater than the preset rotational speed or the left / right change speed, that is, excessively fast or excessively left or right fluctuation occurs, the controller ( 60 returns the control flow to the input sensing step S2110 as a standby state for re-entry without proceeding to the step for operating the haptic rotary switch driver. On the other hand, when the controller 60 determines that the input signal is in a normal input state, the controller 60 switches the control flow to step S2130. When it is determined that the dialing haptic switch unit 10 is normally operated in the input haptic performing step (S2130), the controller 60 is preset to the sensing signal and the storage unit 70 that are input in the input sensing step (S2110). A control signal for driving the haptic rotary switch driver is output based on an operating state value according to the stored operation mode of the haptic rotary switch driver. That is, the haptic rotary switch driver provides a rotational force so that the user can feel the rotational reaction force through the haptic rotary switch knob. The rotational force for forming the rotational force may be formed as a hemisphere waveform as shown in FIGS. 8 and 9. . As described above, the user can recognize a sense of detent and a predetermined dial (phone number) corresponding position through the haptic rotary switch knob by the rotational force input through the haptic rotary switch driver.

Thereafter, the control unit 60 performs a signal determination step (S220), and whether the dialing signal input by the user is determined based on a signal input through the dialing haptic switch unit 10 in the signal determination step (S220). And the dialing digit is extracted from it. The signal determination step S220 includes a signal change determination step S2201 and a dialing digit extraction step S2203. The signal change determination step S2201 includes an input signal change value (△ input signal) calculation step (S2210) and an input. A signal change detection step S2220 and an input signal change value comparison step S2230 are included. First, the control unit 60 performs the input signal change value calculation step S2210. The control unit 60 may have a configuration including a calculation function or a configuration in which a separate calculation unit is added. It is possible. That is, the controller 60 calculates the signal variation value based on the signal input in the signal input step S210 through the dialing haptic switch unit 10 in the input signal change value calculation step S2210. In operation S2210, the input signal change value is calculated by comparing the input signal with the current input signal. Thereafter, the controller 60 determines whether a change value exists in the input signal change detection step (S2220). When it is determined in step S2220 that there is no change in the input signal, that is, when it is determined that the input signal change value is zero, the control flow returns to step S2110 to return to detecting whether the input signal is present. On the other hand, when the controller 60 determines that the input signal change value exists, the controller 60 compares the input signal change value with the preset input change value stored in the storage unit 70 by comparing them with each other. The change degree of the input signal change value is compared and determined (S2230). In the input signal change value comparison step (S2230), when the controller 60 determines that the calculated input signal change value (△ input signal) is smaller than the preset input change value, the signal input through the dialing haptic switch unit is The control flow returns to step S2110 without being regarded as weak and determined not by the user's intended operation. On the other hand, if the control unit 60 determines that the calculated input signal change value is greater than or equal to the preset input change value, it is determined that the operation intended by the user is input through the dialing haptic switch unit and the control flow is extracted. Proceed to S2203. As described above, the signal change determination step (S2201) may determine whether the user intentionally generated the input signal through the dialing haptic switch unit 10 by determining whether the input signal is changed and whether it is within an appropriate range.

Thereafter, the controller 60 performs a dialing digit extraction step (S2203). In the dialing digit extraction step (S2203), the control unit 60 extracts a digit (number) of the dialing (phone number) selected by the user. The dialing digit extraction step S2203 includes a selection determination step S2240 and a digit storing step S2250. The selection determination step S2240 includes a selection time comparison step S2241 and an input signal redetection step S2242. And a recomputation step S2243 of input signal change value (? Input signal), and a recomparison step of input signal change S2244. In the selecting time comparing step S2241, the control unit 60 compares the selecting time t with the selecting reference time ts previously stored in the storage unit 70, where the selecting time t and The selecting reference time ts represents a time coefficient and a preset time constant for measuring a time interval during which the haptic rotary switch sensing unit of the dialing haptic switch unit 10 is maintained without changing the input signal. That is, when the selection time t is less than or equal to the selection reference time ts, the controller 60 switches to the standby state for determining whether the haptic rotary switch knob is subsequently operated by the user, while selecting If the time t is greater than the selection reference time ts, the control unit 60 expands to a control flow that determines that the digit corresponding to the selected position operated by the user is the digit selected by the user. That is, when the control unit 60 determines that the selection time t is less than or equal to the selection reference time ts in the selecting time comparison step S2241, the control unit 60 transfers the control flow to the step S2242 to input the signal. The rediscovery step (S2242) is performed. In the input signal redetection step S2242, the dialing haptic switch unit 10 detects whether a new input signal is introduced, and the detected signal is transmitted to the controller 60. Then, the control unit 60 performs an input signal change value recomputation step S2243, and calculates a signal variation value based on the signal obtained in the input signal redetection step S2242 through the dialing haptic switch unit 10. In operation S2243, an input signal change value is calculated by comparing the input signal input in step S2110 with the signal detected again in step S2242. Thereafter, the control unit 60 determines whether the change value exists in the input signal change recomparison step S2244 and the input signal change value obtained in steps S2242 and S2210 and the preset input change value preset stored in the storage unit 70. If the control unit 60 determines that the calculated input signal change value (△ input signal) is smaller than the preset input change value by comparing and determining the change degree of the input signal change value by comparing the two based on the step S2245 Increments the selecting time t and returns to step S2241 to repeat. On the other hand, when the controller 60 determines that the calculated input signal change value (Δ input signal) is equal to or greater than the preset input change value, the control unit 60 proceeds to step S2246 to reset the selecting time t and returns to step S2210. On the other hand, if it is determined in step S2241 that the selection time t is greater than the selection reference time ts, the controller 60 transfers the control flow to step S2247 to reset the selection time t. As described above, in the selection determination step S2240, the user may determine whether the digits as the individual numbers constituting the dial (phone number) selected by the user through the haptic rotary switch knob of the dialing haptic switch unit 10 are determined.

In the present embodiment, in determining whether or not a digit is selected by the user, the structure requires a state to be maintained for a predetermined time. It may take a structure for determining whether to select through the signal input by. That is, the controller 60 detects a signal input through the haptic enter switch unit 360 selected by the user, and immediately determines that the signal input through the rotation of the current haptic rotary switch knob is a digit selected by the user. The decision selection step of determining whether the user selects the digit according to the design specification, such as switching the control flow to the step, may be variously modified.

After step S2247 of the selection determination step S2240 is performed, the controller 60 transfers the control flow to step S2250 to perform the digit storage step S2250. That is, if it is determined in step S2241 that the digit is selected by the user, the control unit 60 may form the digit as a number constituting a predetermined dial (phone number) by storing the selected digit in the storage unit 70. . In some cases, as shown in FIG. 10, the control unit 60 controls the display unit 81 to output an image to the display unit 81 so as to display the currently selected digit (number) and the last selected digit through the display unit 81. You can also create and pass it. In addition, the output unit 80 further includes a voice output unit (not shown) so that the control unit 60 applies a corresponding voice signal preset to the storage unit 70 to the voice output unit for the selected digit so as to be selected by the user. Voice information about the digits may be delivered to the user.

As such, after the signal determination step S220 is finished, the controller 60 transmits the control flow to the signal determination step S230. The signal confirmation step S230 includes a home position return step S2310 and a dialing completion determination step S2320. The signal for the digit (number) selected by the user in the home position return step S2310, that is, the dialing signal and the storage unit The haptic rotary switch knob is returned to its original position based on the operating state value of the haptic rotary switch driver 310 previously stored in 70. That is, in the home position return step (S2310), the controller 60 applies a control signal to the haptic rotary switch driver 310 to return to the home position from the position corresponding to the digit selected by the user and stored in the storage unit 70. The control signal is applied and driven, so that the user may be provided with an analog sense such as manipulating the dial of the dial telephone. After that, after the haptic rotary switch knob is returned to its original position through the haptic rotary switch driver 310, the controller 60 determines whether the dialing is completed (S2320). In the dialing completion determination step (S2320), the control unit 60 uses the number of digits stored in the storage unit 70 and the stored value of the digits, and the number and storage unit of the number of digits (digits) required to make an actual call. The number of numbers stored in 70 is compared to determine whether a predetermined dial (phone number) is completed. If it is determined that the predetermined dial (phone number) is not completed, the controller 60 transfers the control flow to step S2110 to perform the signal input step again. On the other hand, if it is determined in step S2320 that the predetermined dial (telephone number) is completed, the control unit 60 transmits the control flow to step S300 to perform the terminal number output step S300, and the control unit 60 determines the predetermined number. The control signal for making a call is transmitted to the terminal output unit 85 and the terminal output unit 85 is controlled to transmit and receive through a mobile communication terminal 86 connected to a separate terminal antenna or the terminal output unit 85. It may be.
