Here, state analysis may mean accuracy of the painting area, drawing accuracy, etc. for the content displayed in the work area 7.

That is, the control module 156 generates a first control signal when the painting area deviates from the touch operation by the brush parallel 240 and then provides it to the digital input device 200, thereby generating a first control signal within the digital input device 200. Vibration may be generated by controlling the haptic motor 270 to a first haptic vibration type. In addition, when the drawing accuracy is outside the preset threshold range, the control module 156 generates a second control signal and provides it to the digital input device 200 to set the haptic motor 270 to the second haptic vibration type. Vibration can be generated through control. Through this method, the control module 156 transmits various types of control signals based on the painting or drawing state according to the touch by the brush parallel 240 of the digital input device 200 to control the digital input device 200 individually. It can be vibrated with different haptic vibration types.
