1 is a view showing a wearable device 1 according to an embodiment of the present invention, Figure 2 is a block diagram showing the configuration of a wearable device 1 according to an embodiment of the present invention.

The wearable device 1 according to an embodiment of the present invention includes a main body 2 and a band 3. As shown in FIG. 1, the wearable device 1 may be worn on a user's wrist, and provides a user interface that receives a user's movement of an arm and a hand and performs a function corresponding to the operation.

As shown in FIG. 2, the wearable device 1 according to an exemplary embodiment of the present invention includes a sensor array 10, an inertial sensor 20, an operation determining unit 30, a controller 40, and an output unit 60. ).

The sensor array 10 includes a plurality of sensors 11 each sensing a physical change to the epidermis of the body region. As shown in FIG. 1, the sensor array 10 is disposed on a surface where the band 3 is in contact with the body, and each sensor detects a physical change to the epidermis and outputs a sensing signal. The density of the sensors constituting the sensor array 10 may be proportional to the muscle density below the epidermis of the corresponding body region.

The inertial sensor 20 may include an acceleration sensor and a gyro sensor. The inertial sensor 20 may detect an inertial change that is changed by a user rotating a wrist or lifting an arm, and output the inertial signal.

The operation determiner 30 determines an operation input by the user based on the sensing signals received from the plurality of sensors 11. The operation determiner 30 compares the strength of the sensing signals received from the sensors with a stored value and determines what operation the user takes to determine which operation the user inputs. In addition, the operation determiner 30 may determine an operation input by the user based on the inertial signal measured by the inertial sensor 20 and the sensing signals received from the plurality of sensors 11 of the sensor array 10. .

The operation determiner 30 determines whether the continuous operation input by the user is a continuous operation allowed in the current mode state based on the current mode state and the sensing signals collected from the plurality of sensors 11. Determine what kind of motion is continuous operation. A process of determining an operation input by the user will be described later.

The controller 40 switches between the standby mode M1, the quick mode M2, and the active mode M3 according to the user's operation input from the operation determiner 30 and the duration of each mode, and the quick In the mode M2 state, if the second operation is not input within the first time, the standby mode M1 is switched. That is, the wearable device 1 according to an embodiment of the present invention provides three modes to the user, a standby mode M1, a quick mode M2, and an active mode M3. As shown in FIG. 3, the standby mode M1, the quick mode M2, and the active mode M3 are switched with each other based on the user's input and the duration of each mode.

The standby mode M1 is a state waiting for an input or a notification, etc., which may come from the user or another electronic device connected to the wearable device 1. The standby mode M1 may save the battery by keeping the output unit 60 in an inactive state, and may receive only a predetermined input to release the standby mode M1. For example, the standby mode M1 is released only when the user inputs a first gesture (for example, a fist clenching gesture).

The active mode M3 maintains a state capable of providing all functions of the wearable device 1 to the user. In the active mode M3, the user's operation can be input using the sensor array 10 and the inertial sensor 20, the user's voice input can be received through the voice recognition unit 50, and the communication unit 70. It can perform a function associated with the external electronic device connected by using), and provides the screen, sound, vibration, etc. to the user by using the output unit 60.

Quick mode (M2) provides the user with an environment that can execute the quick function according to the quick operation. The duration of the quick mode (M2) is set considerably shorter than the duration of the active mode (M3), and automatically enters the standby mode if an operation for switching to the active mode (M3) is not entered within the duration of the quick mode (M2). Switch to M1. For example, the duration of the quick mode M2 may be set as short as 2 seconds or 3 seconds, and the switching mode from the standby mode M1 to the quick mode M2 and the active mode M3 within 3 seconds is changed. If no two actions (for example, a fist-up and thumb-up) are entered, the unit automatically enters the standby mode (M1).

In the quick mode M2, the wearable device 1 recognizes the user's operation and releases the standby mode M1 even if the user does not intend to input the operation of releasing the standby mode M1 to the wearable device 1. Just in case. If the standby mode M1 is released and immediately enters the active mode M3, despite the user's intention, various functions are detected by the user's motion or the screen of the active mode M3 is displayed. During the display 61, the battery is exhausted, and the use time of the wearable device 1 is rapidly reduced.

Therefore, the quick mode M2 exists between the standby mode M1 and the active mode M3, so that even if the user does not intend to release the standby mode M1, the quick mode M2 enters the quick mode M2 and the quick mode ( If the user does not input an operation for entering the active mode M3 within the duration of M2), the device automatically switches to the standby mode M1, thereby preventing the user from entering the active mode M3 unintentionally and draining the battery. There is an advantage that can be extended to reduce the use time of the wearable device (1).

That is, even when the user does not intend to release the standby mode M1, the wearable device 1 is not immediately switched to the active mode M3, but is switched to the quick mode M2 having a short duration. It is advantageous to prevent the non-functional performance and to extend the use time of the wearable device 1 by reducing the battery consumption of the wearable device 1.

3 is a diagram illustrating a mode interface provided by the wearable device 1 according to an exemplary embodiment.

As shown in FIG. 3, when the first operation is input from the user in the standby mode M1, the controller 40 switches to the quick mode M2 and within a first time from the user in the quick mode M2. When a second operation is input, the user switches to the active mode M3, and when there is no input from the user in the active mode M3, the user switches to the standby mode M1, and the third operation is performed by the user in the standby mode M1. If is inputted, the mode is switched to the active mode M3.

According to an embodiment of the present invention, the wearable device 1 may set a third operation for immediately switching to the active mode M3 from the standby mode M1 without going through the quick mode M2. Accordingly, the wearable device 1 according to an embodiment of the present invention provides two paths for releasing the standby mode M1 to the user. That is, the first path is to switch to the quick mode (M2) by entering the first operation in the standby mode (M1) and to switch to the active mode (M3) by entering the second operation in the quick mode (M2), the second path is In the standby mode M1, the third operation is inputted, thereby immediately switching to the active mode M3.

In this case, the first operation and the second operation may be set as a single operation using the user's hand, and the third operation may be set as the continuous operation using the user's hand. It is preferable to set the continuous operation set as the third operation to an operation having low association between each operation. Since the user is unlikely to correctly perform the continuous operation set as the third operation in the process of wearing the wearable device 1 and living, it is possible to prevent the user from entering the active mode M3 unintentionally. If the user wants to enter the active mode (M3) is because the continuous operation can be performed correctly.

As such, when entering the active mode M3 using the first operation, the second operation, and the third operation, a command using a voice may be input in the active mode M3. When the user speaks a command, the voice recognition unit 50 recognizes the user's voice and determines whether the command is a predetermined command, and transmits the command to the control unit 40. The conventional method of entering the active mode (M3) using the voice has a problem in that it is inconvenient, and the recognition rate of the voice recognition itself is low because it has to say a specific word. In contrast, the wearable device 1 according to an embodiment of the present invention enters the active mode M3 using a user's hand or arm operation and provides an environment in which a command can be issued by voice.

Meanwhile, when the controller 40 receives a quick operation from the user in the quick mode M2, the controller 40 may perform a function corresponding to the quick operation in the quick mode M2. The quick mode M2 provides an environment in which the user can perform a necessary function without entering the active mode M3, in addition to the above-mentioned function of preparing for the user's unintentional release of the standby mode M1. Quick mode (M2) is displayed to the user using any one of the screen, sound or vibration using the output unit 60 to switch to the quick mode (M2) from the standby mode (M1). This informs the user of the entry into the quick mode (M2) to inform the user that the quick function is available.

It is preferable that the quick operation which can be input in the quick mode M2 is set to continuous operation. Since the user has a low probability of accurately performing the continuous operation set to the quick operation in the process of wearing the wearable device 1 and living, it is possible to prevent the user from performing the quick function unintentionally.

Quick functions provided in the quick mode M2 may be classified into controlling the wearable device 1 itself and controlling an external device connected using the wearable device 1. If the quick function controls the wearable device 1 itself but does not need to provide a screen (such as controlling the volume of the speaker 62), the device directly related to performing the function in the quick mode M2 (speaker ( 62), and may not provide a screen through the display 61. In addition, even when performing a quick function of controlling an external device in the quick mode M2, the screen may not be provided on the display 61 of the wearable device 1.

The quick function of the quick mode M2 provides a convenient environment in which a user can perform a predetermined function without looking at the display 61 of the wearable device 1, and does not display a screen while performing the quick function. In (1), the operation of the portion of the display 61 which consumes the most battery can be omitted, so that the use time of the wearable device 1 is extended. That is, by the user inputting the quick operation in the quick mode M2, there is an advantage that the function corresponding to the quick operation can be performed without entering the active mode M3 which consumes a lot of battery.

Hereinafter, an interface method of the wearable device 1 according to an exemplary embodiment of the present invention will be described.

3 is a view showing a mode interface provided by the wearable device 1 according to an embodiment of the present invention, Figure 4 is a switching operation of the mode interface provided by the wearable device 1 according to an embodiment of the present invention It is a flow chart showing.

In the interface method of the wearable device 1 according to an embodiment of the present invention, the sensor array 10 including a plurality of sensors 11 detects a physical change to the epidermis of a corresponding body region, and determines an operation determining unit ( 30 determines whether the user inputs an operation based on the sensing signals received from the plurality of sensors 11 in operation S200 and in the standby mode M1, and determines whether the first operation is input from the user. In operation S101, when the first operation is input, the second operation is input within the first duration from the user in the standby mode M1 releasing step of switching to the quick mode M2 and in the quick mode M2 state. In operation S103, if the second operation is not input within the first duration, the operation is switched to standby mode M1 (S104), and if the second operation is received within the first duration, an active mode. Quick mode (M2) release step and active mode (M3) are switched to (M3) (S105). In the state, if the input is not received from the user within the second duration (S106) includes the step of activating the active mode (M3) to switch to the standby mode (M1).

In the operation input step (S200), the operation determination unit 30 determines the user's operation based on a signal input from the plurality of sensors 11 and the inertial sensor 20 of the sensor array 10 and input by the user Determine the action to perform. The process of determining the operation in the operation determiner 30 will be described later.

In the step of releasing the standby mode M1, the controller 40 determines whether the operation of the user provided by the operation determiner 30 matches the predetermined first operation (S101). When it is determined that the user inputs the first operation, the user switches to the quick mode M2 (S102), and maintains the standby mode M1 when the user inputs an operation other than the first operation.

At this time, the quick mode (M2) display step of notifying the user of switching to the quick mode (M2) by using one of the screen, sound or vibration while switching to the quick mode (M2) from the standby mode (M1) (S102). May be further performed. In response to the user notifying the switch to the quick mode M2, the user can recognize that a quick action can be input.

In addition, in the step of releasing the standby mode M1, it is determined whether a third operation is input from the user in the standby mode M1 state (S101), and when the third operation is input, switching to the active mode M3 (105). can do. As such, when the user inputs the first operation in the standby mode M1, the standby mode M1 is released while switching to the quick mode M2, and when the user enters the third operation, the standby mode M1 is switched to the active mode M3. The standby mode M1 is released.

On the other hand, when a quick operation is received from the user in the quick mode (M2) state, a quick function performing step of performing a function corresponding to the quick operation in the quick mode (M2) state may be further performed. In the quick function performing step, performing a quick function corresponding to the quick operation input by the user, and after performing the quick function, counting the first time from the beginning and determining whether the second operation is input within the first time (S103). Will be performed.

Through this process, the interface method of the wearable device 1 according to an embodiment of the present invention provides switching of the standby mode M1, the quick mode M2, and the active mode M3 according to a user's operation input. In addition, even when the standby mode M1 is released by an unintended input by the user, the user does not immediately enter the active mode M3, thereby preventing malfunction of the wearable device 1 and reducing battery consumption.

Hereinafter, the operation input step S200 will be described with reference to FIGS. 5 and 6.

5 is a flowchart illustrating a process of determining a user's operation by the wearable device 1 according to an embodiment of the present invention, and FIG. 6 is a view of the wearable device 1 according to an embodiment of the present invention. A diagram illustrating an exemplary gesture.

The interface method of the wearable device 1 according to an exemplary embodiment of the present invention provides an environment in which a user may input a single operation and a continuous operation, and sets the continuous operation and the single operation different from each other according to the mode. Can be. As shown in FIG. 6, a user may input a single action of independently inputting each action (eg, (a), (b), (c) and (d) of FIG. 6). In addition, as shown in Table 1 below, it is also possible to input the continuous operation.

First, in the current motion detection step (S201), when a user performs a specific motion, the sensor array 10 including the plurality of sensors 11 detects a physical change to the epidermis of the corresponding body region, and detects the sensing signals. The inertial sensor 20 provides an inertial signal to the operation determining unit 30. The operation determiner 30 compares the sensing signals received from the plurality of sensors 11 and the inertial signals received from the inertial sensor 20 with a signal value of each operation stored in advance to perform an operation input by the user. Detect.

The operation determination unit 30 checks what the current mode is (S202). The step of checking the current mode may be located before the current motion detection step, and may use a method of automatically updating the current mode to the operation determination unit 30 when the mode is switched.

When the current mode is confirmed, the operation determination unit 30 determines whether the operation detected in the current operation detection step S201 is the initial operation of the continuous operation designated in the current mode (S203). As illustrated in Table 1 above, the standby mode M1, the quick mode M2 and the active mode M3 provide single operations and continuous operations that can be input in each mode. In each mode, since the initial operation of the single operation and the continuous operation is set to the same operation, it may be determined whether the operation input by the user is the continuous operation.

If the operation detected in the current operation detection step S201 is not the initial operation of the continuous operation designated in the current mode, the operation determination unit 30 is an operation input by the user as the operation detected in the current operation detection step S201. The determination step (S204) is performed. In this case, the operation that the operation decision unit 30 provides to the control unit 40 is a single operation.

For example, referring to the quick mode M2 of Table 1, when the user performs the operation c, the operation determination unit 30 detects the operation c based on the sensing signal (S201), and the current mode is selected. In operation S202, it is determined whether the basic operation (operation a) of the continuous operation provided in the quick mode M2 and the detected operation c match (S203). Therefore, the operation c is determined as a single operation input by the user. .

On the other hand, if the motion detected in the current motion detection step is the initial motion of the continuous motion specified in the current mode, the operation determiner 30 detects the next motion (S205) and determines the continuous motion input by the user ( S206). In this case, the operation that the operation decision unit 30 provides to the control unit 40 is a continuous operation.

Detecting the next operation (S205) detects the operation performed by the user through the current operation detection step (S201), and determines whether the operation is consistent with the intermediate operation of the continuous operation of the current mode, and if it matches, the next operation through the same process Can be detected. When all of the predetermined initial operation, intermediate operation, and completion operation of the continuous operation are detected, the operation determination unit 30 determines that the user inputs the continuous operation (S206), and provides the continuous operation to the controller 40.

When the intermediate operation or the completion operation is not detected in the step S205 of detecting the next operation, the operation determination unit 30 determines that the user has detected an unintended input, and initially receives the user's input from the beginning. Returning to the state, the control unit 40 does not provide an operation.

For example, referring to the quick mode M2 of Table 1, when the user performs the operation a, the operation determination unit 30 detects the operation a based on the sensing signal (S201), and selects the current mode. In step S202, it is determined whether or not the basic operation (operation a) of the continuous operation provided in the quick mode M2 matches the detected operation a (S203). Therefore, the next operation is detected (S205). When the intermediate operation (operation c) and the completion operation (operation b) are sequentially detected, the user determines that the user inputs the quick operation that is a continuous operation to perform the quick function, and provides the determined continuous operation to the controller 40. .

Through this process, the operation determiner 30 may determine whether the operation input by the user is a single operation or a continuous operation. As illustrated in Table 1, the continuous operation may be set differently for each mode, and thus, the continuous operation may be configured as an operation that is easy for a user to input in each mode. In addition, even if the same single operation or continuous operation is input, it can be set to perform different functions depending on the mode. If the same operation is set to perform different functions depending on the mode, there is an advantage that a limited operation can be utilized as various functions.

Although the present invention has been described in detail through specific examples, it is intended to describe the present invention in detail, and the present invention is not limited thereto, and should be understood by those skilled in the art within the technical spirit of the present invention.
