Figure 2 is a perspective view of the user input device of Figure 1;

Hereinafter, the present invention will be described in detail with reference to the embodiments and the drawings.

1 is a configuration diagram of a user input device for applying a fine current according to the present invention.

The user input device includes a power unit 1 for applying necessary power to other components, a wheel button 3 capable of rotating around a reference axis for a scroll function, and a left button 5a and a right button 5b A fine current generator 7 for generating a fine current and applying the generated fine current to the first and second electrodes E1 and E2; A display unit 9, a communication unit 11 for communicating with an external electronic device (for example, a computer main body or the like) in a wired or wireless manner, an operation sensing unit 13 for sensing movement (movement) The first and second electrodes E1 and E2 are controlled by controlling the micro current generator 7 while receiving power from the power supply unit 1 and performing a user input function such as a mouse or the like (scroll function, selection input, And a control unit 20 for applying a fine current through the control unit 20. However, the power source unit 1, the wheel button 3, the selection button 5, the communication unit 11, and the motion sensing unit 13 are not limited to those of ordinary skill in the art. Description thereof is omitted.

The fine current generating unit 7 receives power from the power source unit 1 and generates a biphasic pulse type fine current according to the fine current applying command of the controller 20 to generate the first and second leads L1, (L2) to the first and second electrodes (E1, E2). The abnormal pulse current is composed of a forward pulse having a predetermined width in one cycle, a reverse pulse having a predetermined width continuous to the forward pulse, and a blocking period (current size is zero) continuous to the reverse pulse, The magnitude (absolute value) of the forward pulse is equal to the magnitude (absolute value) of the backward pulse, and is preferably in the range of 40 to 300 占., For example. The micro-current generating unit 7 stops generating and applying the micro-current according to the micro-current cutoff command from the control unit 20. [ The microcurrent generating unit 7 acquires a command for the intensity of the microcurrent from the controller 20 and supplies the microcurrent of the obtained intensity to the first and second electrodes E1, (E2).

The first and second electrodes E1 and E2 are electrically insulated from each other, are made of a conductive material, and are exposed to the outside.

The display unit 9 transmits and cuts off micro currents and intensity (intensity) of micro currents through color, blinking, and blink speed.

The control unit 20 acquires the input from the wheel button 3 and the selection button 5 and selects the position where the pointer is positioned in the same manner as the function of the mouse by detecting the motion by the motion sensing unit 13, The minute current generating unit 7 can be controlled to simultaneously apply and interrupt the minute current while performing the movement of the pointer. In the present embodiment, description will be made mainly on a configuration in which the control section 20 applies a fine current.

First, function control for applying and interrupting the current-mirror function is described. The controller 20 controls the operation of the microcurrent generator 7 while the power is being supplied from the power supply 1 while the microcurrent generator 7 is shut down (or while maintaining the microcurrent blocking function with respect to the microcurrent generator 7) (For example, receiving a detection signal indicating that the user input device is not moving from the motion detection unit 13) or receiving a detection signal indicating that the user input device is moving from the motion detection unit 13 , The control unit 5 continuously obtains the selection input (push input) from one of the selection buttons 5 (for example, the left button 5a) (For example, right button 5b) is pressed for more than a reference time (for example, 3 seconds) and continuously obtains the selection input for more than the reference time, the fine current generating section 7 is controlled to control the first and second Electrodes E1, E 2 to generate and apply a fine current to the fine current generator 7, thereby performing a fine current application function.

On the other hand, when the control unit 20 is operating while the micro-current generating unit 7 is operating (while performing the micro-current applying function with respect to the micro-current generating unit 7) and power is supplied from the power source unit 1, When there is no movement of the apparatus, the selection input (push input) from one of the selection buttons 5 (for example, the left button 5a) When the button (for example, the right button 5b) is depressed for a predetermined time (for example, 3 seconds) to continuously obtain the selection input for more than the reference time, Generates a current cutoff command and applies it to the fine current generating unit 7 to convert the fine current applying function into the fine current cutoff function.

As described above, in order to perform the switching between the fine current application function and the shutoff function, the control unit 20 controls the current operation state (application / cutoff operation) of the microcurrent generation unit 7 and the operation state detection unit 13 (Input sequence and input duration) of the left / right buttons 5a and 5b of the selection button 5 and the movement state (movement / non-movement) of the user input device itself do. The control unit 20 allows the user to recognize the micro current application function and the blocking function through the display unit 9. [

Next, the process of adjusting the intensity (intensity) of the microcurrent is explained. The control unit 20 controls the micro current generating unit 7 to perform the micro current application function so that if there is no movement of the user input device, one button of the selection button 5 (for example, the right button 5b ) Is continuously depressed for more than the reference time (for example, 5 seconds), and when the selection input is continuously obtained over the reference time, it is converted into the input waiting state for controlling the intensity of the microcurrent. In the input waiting state, the control unit 20 sets the magnitude of the micro current based on the direction in which the wheel button 3 rotates (or the direction in which the pointer moves) by the user . The control unit 20 cancels the input waiting state for adjusting the intensity of the minute current when the additional rotation input from the wheel button 3 is not present for the reference time or the input standby state continues for the reference time or more. The control unit 20 controls the microcurrent generation unit 7 based on the intensity of the microcurrent set at the time of canceling the input standby state so that the set microcurrent flows through the first and second electrodes E1 And E2, respectively. Further, the control unit 20 displays the set intensity of the minute current through the display unit 9.

As described above, in order for the controller 20 to control the intensity of the microcurrent, the current operation state (application operation) of the microcurrent generator 7 and the movement of the user input device itself by the motion detection unit 13 (Input / output) state of the right button 5b of the selection button 5 and the input state of the right button 5b of the selection button 5, The intensity of the minute current is directly controlled within a predetermined range according to the input of the wheel button 3 of the wheel button 3.

Figure 2 is a perspective view of the user input device of Figure 1; The user input device includes an upper case 30a formed with a wheel button 3 and a selection button 5 and a lower case 30b which is in contact with a top surface of a desk or a mouse pad and is coupled to the upper case 30a A microcurrent generating unit 7, a communication unit 11, a motion sensing unit 13, and a controller 20 (not shown) in an internal space created by coupling the upper case 30a and the lower case 30b. . However, the motion sensing unit 13 may be mounted on the bottom surface of the lower case 30b so as to be exposed to the outside.

The upper case 30a is provided with a display portion 9 for displaying the state of application / cutoff of a minute current, and the like. The display portion 9 is exposed to the outside of the upper case 30a, 1 and second electrodes E1 and E2. The first and second electrodes E1 and E2 are spaced apart from each other by a predetermined distance and the hand or wrist of the user electrically connects the first and second electrodes E1 and E2, . Since the control unit 20 can simultaneously perform the fine current application and the shutoff function while performing the function of the normal user input device, a minute current flows to the user's hand or wrist while the user is using the user input device, A healing operation can be performed.
