Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals denote the same members.

1 is a view showing a wearable device 1 according to an embodiment of the present invention, and FIG. 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 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 motion of the user's arm and hand and performs a function corresponding to the motion.

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

The sensor array 10 includes a plurality of sensors 11 that respectively detect physical changes to the epidermis of a corresponding body region. As shown in FIG. 1, the sensor array 10 is disposed on a surface of the band 3 in contact with the body, and each sensor senses a physical change on the skin and outputs a sensing signal. The density of the sensors constituting the sensor array 10 may be proportional to the density of muscles under the epidermis of the body region.

The inertial sensor 20 may include an acceleration sensor, a gyro sensor, or the like, and detects a change in inertia that changes due to a motion of rotating a wrist or lifting an arm by a user, and outputs an inertial signal.

The operation determination unit 30 determines an operation input by the user based on sensing signals received from the plurality of sensors 11. The operation determination unit 30 compares the intensity of sensing signals received from the sensors with a stored value, determines what operation the user takes, and determines which operation the user inputs. In addition, the operation determination unit 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 determination unit 30 determines whether the user inputs the continuous operation based on the current mode state and the sensing signals collected from the plurality of sensors 11 and inputs it by the user. Decide which motion is the continuous motion to be performed. The process of determining the operation input by the user will be described later.

The control unit 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 determination unit 30 and the duration of each mode, and In the mode M2 state, if the second operation is not input within the first time period, it is switched to the standby mode M1. 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 to each other based on the user's input and the duration of each mode.

The standby mode M1 is a state in which an input or a notification that may come in from a user or another electronic device connected to the wearable device 1 is awaited. In the standby mode M1, battery can be saved by maintaining the output unit 60 in an inactive state, and only a predetermined input can be input to cancel the standby mode M1. For example, the standby mode M1 is released only when the user inputs a first motion (eg, clenching a fist).

The active mode M3 maintains a state in which all functions of the wearable device 1 can be provided to a user. In the active mode (M3), the user's motion can be input using the sensor array 10 and the inertial sensor 20, and the user's voice input can be input through the voice recognition unit 50, and the communication unit 70 ) Can be used to perform functions related to external electronic devices that are connected, and provide a screen, sound, and vibration to the user using the output unit 60.

The quick mode (M2) provides an environment in which a user can execute a quick function according to a quick operation. The duration of the quick mode (M2) is set considerably shorter than the duration of the active mode (M3), and if an operation to switch to the active mode (M3) is not input within the duration of the quick mode (M2), the standby mode automatically It is converted to (M1). For example, the duration of the quick mode (M2) may be set as short as 2 or 3 seconds, and the switch from the standby mode (M1) to the quick mode (M2) and to the active mode (M3) within 3 seconds. 2 If no action (eg, clenching a fist and raising a thumb) is input, it automatically switches to the standby mode (M1).

In the quick mode (M2), the wearable device 1 recognizes the user's motion and releases the standby mode (M1) even if the user does not intend to enter the operation of releasing the standby mode M1 into the wearable device 1. Just in case. If the standby mode (M1) is released and immediately enters the active mode (M3), various functions are executed by detecting the user's motion, or the screen of the active mode (M3) is displayed. In the process of displaying 61, the battery is consumed, and the usage time of the wearable device 1 rapidly decreases.

Therefore, since the quick mode M2 exists between the standby mode M1 and the active mode M3, the user enters the quick mode M2 even if the user unintentionally cancels the standby mode M1 and enters the quick mode. If the operation to enter the active mode (M3) is not input within the duration of M2), it is automatically switched to the standby mode (M1), thus preventing the user from unintentionally entering the active mode (M3) and draining the battery. There is an advantage in that the use time of the wearable device 1 can be extended by reducing the value.

That is, even if an unintended standby mode (M1) release operation is input to the wearable device (1), the user does not immediately switch to the active mode (M3) and switches to the quick mode (M2) with a short duration. There is an advantage of prolonging the use time of the wearable device 1 by preventing the execution of functions that have not been performed and reducing the battery consumption of the wearable device 1.

3 is a diagram showing a mode interface provided by the wearable device 1 according to an embodiment of the present invention.

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) state. When the second operation is input, it switches to the active mode (M3), and if there is no input from the user in the active mode (M3), it switches to the standby mode (M1), and the third operation from the user in the standby mode (M1) When is input, it is switched to the active mode M3.

In the wearable device 1 according to an embodiment of the present invention, a third operation for immediately switching from the standby mode M1 to the active mode M3 without passing through the quick mode M2 may be set. 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 inputting 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), and the second path is In the standby mode (M1), the third operation is input to immediately switch to the active mode (M3).

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

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

Meanwhile, when receiving a quick operation from a user in the quick mode (M2) state, the control unit 40 may perform a function corresponding to the quick operation in the quick mode (M2) state. The quick mode M2 provides an environment in which a user can perform a required function without entering the active mode M3, in addition to the function for preparing the user to unintentionally release the standby mode M1. In the quick mode M2, the conversion from the standby mode M1 to the quick mode M2 is displayed to the user using one of a screen, sound, or vibration using the output unit 60. This is to inform the user of the entry into the quick mode (M2) that the quick function is available.

It is preferable to set the quick operation that can be input in the quick mode (M2) state to a continuous operation. Since the probability of accurately performing the continuous operation set as the quick operation in the process of the user wearing the wearable device 1 and living the life is low, it is possible to prevent the user from performing an unintended quick function.

The quick function provided in the quick mode (M2) state can be classified as 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), a 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 a quick function for controlling an external device is performed in the quick mode M2, a 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 the user can perform a specified 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), it is possible to omit the operation of the portion of the display 61 that consumes the most battery, and thus there is an advantage 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 a 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 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, and FIG. 4 is a switching operation of the mode interface provided by the wearable device 1 according to an embodiment of the present invention. Is a flow chart showing.

In the interface method of the wearable device 1 according to an embodiment of the present invention, a sensor array 10 including a plurality of sensors 11 detects a physical change to the epidermis of a corresponding body region, and an operation determination unit ( 30) The operation input step (S200) of determining an operation input by the user based on the sensing signals received from the plurality of sensors 11, in the standby mode (M1) state, it is determined whether the first operation is input from the user (S101), and when the first operation is input, the standby mode (M1) release step of switching to the quick mode (M2) (S102), in the quick mode (M2) state, the second operation is input by the user within the first duration If the second operation is not input within the first duration (S103), it switches to the standby mode (M1) (S104), and if the second operation is received within the first duration, the active mode In the quick mode (M2) release step of switching to (M3) (S105) and the active mode (M3), when no input from the user is received within the second duration (S106), the standby mode (M1) is switched to It includes a step of canceling the active mode (M3).

In the motion input step (S200), the motion determination unit 30 determines the user's motion based on signals input from the plurality of sensors 11 and the inertial sensor 20 of the sensor array 10 and inputs the user. Decide what action to do. A process of determining an operation in the operation determination unit 30 will be described later.

In the standby mode (M1) releasing step, the control unit 40 determines whether the user's operation provided by the operation determination unit 30 matches the first predetermined operation (S101). If it is determined that the user has input the first operation, the operation is switched to the quick mode M2 (S102), and when the user inputs an operation other than the first operation, the standby mode M1 is maintained.

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

In addition, in the standby mode (M1) release step, 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 inputted, it is switched to the active mode (M3) (105). can do. In this way, when the user inputs the first operation in the standby mode (M1), it is converted to the quick mode (M2) and the standby mode (M1) is released, and when the user inputs the third operation, it is switched to the active mode (M3). The standby mode (M1) is released.

Meanwhile, when a quick operation is received from the user in the quick mode M2 state, a quick function execution step of performing a function corresponding to the quick operation in the quick mode M2 state may be further performed. In the quick function execution step, a step of 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 a second operation is input within the first time (S103 ).

Through this process, the interface method of the wearable device 1 according to an embodiment of the present invention provides switching of a standby mode (M1), a quick mode (M2), and an active mode (M3) according to a user's motion input. In addition, even if the standby mode M1 is released due to an unintended input by the user, it 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.

FIG. 5 is a flowchart showing a process in which the wearable device 1 determines a user's operation according to an embodiment of the present invention, and FIG. 6 is a flow chart that can be recognized by the wearable device 1 according to an embodiment of the present invention. It is a diagram showing an exemplary gesture.

The interface method of the wearable device 1 according to an embodiment of the present invention provides an environment in which a user can input a single motion and a continuous motion, and differently set a continuous motion and a single motion that can be input according to the mode. I can. As shown in FIG. 6, the user may input a single action for independently inputting each action (eg, (a), (b), (c), (d) of FIG. 6). In addition, as shown in Table 1 below, continuous operation may be input.

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

The operation determination unit 30 checks what the current mode is (S202). The step of confirming the current mode may be located before the step of detecting the current operation, and when the mode is changed, a method of automatically updating the current mode to the operation determination unit 30 may be used.

When the current mode is confirmed, the operation determination unit 30 determines whether the operation detected in the current operation detection step S201 is an initial operation of the continuous operation designated in the current mode (S203). As illustrated in Table 1, 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 an operation that is not the same, it can be determined whether the operation input by the user is a continuous operation.

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

For example, referring to the quick mode (M2) in 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 selects the current mode. After checking (S202), it is determined whether the basic operation (action a) of the continuous operation provided in the quick mode (M2) and the detected operation c match (S203), and since they do not match, the operation c is determined as a single operation input by the user. .

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

In the step of detecting the next operation (S205), the operation performed by the user through the current operation detection step (S201) is detected, it is determined whether it matches the intermediate operation of the continuous operation of the current mode, and if it matches, the next operation through the same process. Incomplete operation can be detected. When all of the predetermined initial, intermediate, and completed operations 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 control unit 40.

In the case that an intermediate or complete operation is not detected in the step of detecting the next operation (S205), the operation determination unit 30 determines that an unintended input by the user is detected, and receives the user's input from the beginning. It returns to the state and does not provide an operation to the control unit 40.

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. By checking (S202), it is determined whether the basic operation (operation a) of the continuous operation provided in the quick mode (M2) and the detected operation a are identical (S203), and since they match, a step (S205) of detecting the next operation is performed. , When the intermediate operation (action c) and completion operation (action b) are sequentially detected, it is determined that the user inputs a quick action, which is a continuous action, to perform the quick function, and the determined continuous action is provided to the control unit 40. .

Through this process, the operation determination unit 30 may determine whether the operation input by the user is a single operation or a continuous operation. As illustrated in Table 1, since the continuous operation can be set differently for each mode, there is an advantage that the continuous operation can be configured with 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, different functions can be set according to the mode. If the same operation is set to perform different functions depending on the mode, there is an advantage that limited operations can be used as various functions.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, and the present invention is not limited thereto, and within the technical scope of the present invention, those of ordinary skill in the art It would be clear that the transformation or improvement is possible.

All simple modifications to changes of the present invention belong to the scope of the present invention, and the specific scope of protection of the present invention will be made clear by the appended claims.
