1 to 9 show a system 10; A calculation unit 100; A sensing unit 200, a rotation weight 210; A screen output unit 300; Target value 310; Guideline 320; Task performing space 330; A vision sensor 340; And the manipulating object 400 are shown.

Hereinafter, a work performance measuring system according to embodiments of the present invention will be described with reference to the drawings.

1 is an internal configuration diagram of a work performance measuring system 10 according to an embodiment of the present invention.

Referring to FIG. 1, a work performance measuring system 10 according to an embodiment of the present invention includes a sensing unit 200; A calculation unit 100; And a screen output unit 300.

The sensing unit 200 performs a function of measuring motion data for a specific task performed by the user. The sensing unit 200 may directly sense or indirectly sense an operation for performing a task by the user. The direct sensing may include sensing a movement of a user holding the sensing unit 200 or sensing a pushing or turning operation of a user-operable configuration. Indirect measurement may include recognizing the motion of a distant user through a camera or the like. However, the direct sensing and the indirect sensing are not limited to this, and may include various methods of sensing movement of a user to acquire motion data.

The operation may correspond to a cooking operation performed on the screen by using the screen output unit 300 as a work performing space 330. [ That is, the work performance measuring system 10 is required for real life adaptation of the rehabilitation patients and can perform a cooking operation that can be utilized for job search, etc., and can measure the result of the performance and display a result screen accordingly. The operation may include a bubbling operation, a kneading operation, a kneading operation, a flipping operation, a follow operation, a sprinkling operation, a valve adjusting operation, a frying operation, etc. of the user.

The calculation unit 100 performs a function of performing overall control and information processing required on the system 10. That is, the calculation unit 100 may calculate a real-time performance result of the specific task based on the sensed motion data, and generate a real-time output image corresponding to the performance result. In addition, the calculation unit 100 can determine the accuracy of the task performed by the user, and can calculate the task performance of the user based on the accuracy of the task.

The screen output unit 300 is horizontally disposed on a floor surface, and performs a function of displaying the real-time output image. That is, the screen output unit 300 may be horizontally disposed on the floor surface, and may display an image corresponding to a result of a specific operation performed by the user on the screen output unit 300. In addition, the screen output unit 300 can display the job performing ability calculated by the calculation unit 100 on one side of the screen in numerical or graphic form.

The output image may be a result of performing the cooking operation. For example, as shown in FIG. 2, when the operation performed by the user is a pouring operation of the liquid flow, the degree of spread according to the amount of liquid flow calculated as poured according to the degree of tilt measured by the sensing unit 200 It can be created and displayed as an output image. More specifically, based on the motion data measured in real time from the sensing unit 200 (i.e., the degree of tilt), the calculation unit 100 calculates the degree to which the liquid flow corresponding to the tilt value is swollen and spreads on the floor surface Can be calculated and displayed in real time as an output image.

Also, the screen output unit 300 may be implemented as a touch screen. When the screen output unit 300 is a touch screen, the screen output unit 300 can recognize a touch operation by an operation. The touch operation can be performed by the sensing unit 200 as well as the user's body. For example, as shown in FIG. 6, when the slicing operation is performed, the touch screen (the screen output unit 300) recognizes the touch operation of the sensing unit 200 configured as a knife, It can be measured whether or not the operation is properly performed on the screen. For this, the sensing unit 200 may be provided with a conductive material in a portion contacting the screen output unit 300.

In addition, the screen output unit 300 may display the job guidelines 320 and 310 on the screen. The guidelines 320 and 310 correspond to goals that a user must perform to accomplish and reach. For example, as shown in FIG. 2, in the case of a work following a liquid flow, the screen output unit 300 may include a circular guide line 320 (310) corresponding to a circle in which a liquid spreads It can be displayed on the screen. In this way, the user can perform a liquid flow pouring operation that accurately aligns the work execution graphics on the displayed guidelines 320 (310). 6, the screen output unit 300 may display a linear guide line for performing a slicing operation using the sensing unit 200 configured by a user as a knife, And can be expressed by the guidelines 320 and 310. [

When the screen output unit 300 displays the guide lines 320 and 310 on the screen, the calculation unit 100 can calculate the accuracy of the touch operation with respect to the guide lines 320 and 310 have. For example, as shown in FIG. 6, the accuracy of the task can be measured by accumulating the degree of the user's action performed along the guideline output on the screen output unit 300 based on the guideline. A method of calculating the accuracy of the slicing operation may be a method in which the calculation unit 100 measures an area between a line where the user performs the slicing operation with the sensing unit 200 and a straight line corresponding to the guide lines 320 and 310, And a method of accumulating the error between the line at which the work is performed and a line at a specific interval of the guide line.

In addition, the screen output unit 300 may further include a pressure sensor. The pressure sensor can recognize the intensity with which the user presses the screen when the work performed by the user applies force (or pressure) to the screen. The screen output unit 300 may need to measure whether or not a pressure higher than a specific intensity is applied to the floor surface according to the operation of the operation to be performed. For example, as shown in FIG. 6, when the knife-shaped sensing unit 200 performs a slicing operation on the screen output unit 300, as in the case of applying a pressure of a specific intensity or more to cut a specific material, It is possible to determine whether the pressure applied to the screen output unit 300 is equal to or greater than a specific intensity. If the touch screen can recognize the intensity of the touch operation, it is possible to measure the pressure intensity applied to the screen output unit 300 by the touch screen without a separate pressure sensor.

In addition, the screen output unit 300 may include a plurality of job performing spaces 330 for providing jobs. The screen output unit 300 may display an image corresponding to a different job in the plurality of job execution spaces 330 and may request the user to perform a plurality of jobs in an arbitrary order. The calculation unit 100 generates the output image providing a plurality of jobs in an arbitrary order and transmits the generated output image to the screen output unit 300 for outputting the image, receives the motion data from the sensing unit 200, It is possible to determine whether or not the user performs an operation corresponding to the requested job. As will be described later, the screen output unit 300 recognizes the operation point of the sensing device and measures whether or not the operation is performed at a point corresponding to the operation performing space 330 where the operation is requested. It can be reflected in the image generation.

The sensing unit 200 and the screen output unit 300 may be included in one apparatus and may be included in the separate sensing apparatus and screen output apparatus, respectively. When the sensing unit 200 and the screen output unit 300 are included in one device, the sensing unit 200 may measure (or sense) the user's operation at a distance as in the vision sensor 340, It is possible to recognize the operation of the provided buttons or switches. When the sensing unit 200 and the screen output unit 300 are included in a separate device, the sensing device may measure the motion data corresponding to the operation of the user and transmit the measured motion data to the screen output device. At this time, the calculation unit 100 may be included in the sensing device or the screen output device, and may be configured as a separate device in some cases. For example, when the calculation unit 100 is included in the screen output device together with the screen output unit 300, the sensing unit 200 in the sensing device measures the movement data of the user, (E.g., a cable connected to the device) or wireless (e.g., an indoor network such as a local area network or Wi-Fi). Thereafter, the screen output device may analyze the motion data, calculate the execution result, and generate a corresponding real-time output image to display on the screen.

The sensing unit 200 can measure the degree of tilt, linear acceleration, linear velocity, rotation acceleration, rotation speed, number of rotations, degree of twist, and the like as motion data. For example, when the sensing unit 200 is implemented as a separate sensing device, the degree of tilt, the linear acceleration, the linear velocity, the rotation acceleration, the rotational speed, the number of rotations, All or a part of the motion data of the motion vector can be obtained. When a user performs an operation after a specific job is selected, the sensing unit 200 may measure only the motion data necessary for calculating the execution result of the selected job.

The sensing unit 200 may include a first inertial sensor (IMU sensor) to acquire motion data. The IMU sensor may be a MEMS (Micro Mechanical System) based 9-axis IMU sensor. The 9-axis IMU sensor includes a 3-axis acceleration sensor, a 3-axis gyroscope sensor, and a 3-axis terrestrial magnetism sensor. The 3-axis acceleration sensor measures the mobile inertia (acceleration) of the x-, y-, and z-axes. The 3-axis gyroscope sensor measures the rotational inertia (angular velocity) of the x, y, and z axes. The 3-axis geomagnetic sensor measures the azimuths of the x-axis, y-axis, and z-axis (direction of the geomagnetism). According to another embodiment, the sensing unit 200 may include at least one of an acceleration sensor and a geomagnetic sensor instead of the IMU sensor.

In addition, the work performance measuring system 10 according to an embodiment of the present invention may further include an operation object 400. [ The manipulated object 400 may correspond to an object including the second inertial sensor which is operated by the sensing unit 200 on the screen output unit 300. [ For example, as shown in FIG. 5, when the flip operation is performed, an object (for example, a hull-shaped object such as a flasher) disposed on the screen output unit 300 corresponds to the operation object 400 can do. The user can perform a flip operation of the operation object 400 using a sensing device including the sensing unit 200 (for example, a reversing device in Fig. 5) And transmits the measured state to the calculation unit 100.

In addition, when the operation is a roasting operation, the operation object 400 having a specific shape can be measured and transmitted to the calculation unit 100. The calculation unit 100 can measure the performance of the user based on the changed arrangement state of the manipulated object 400 according to the manipulation using the sensing device of the user.

The second inertial sensor may correspond to an IMU sensor. The IMU sensor may be a MEMS (Micro Mechanical System) based 9-axis IMU sensor. The 9-axis IMU sensor includes a 3-axis acceleration sensor, a 3-axis gyroscope sensor, and a 3-axis terrestrial magnetism sensor. The 3-axis acceleration sensor measures the mobile inertia (acceleration) of the x-, y-, and z-axes. The 3-axis gyroscope sensor measures the rotational inertia (angular velocity) of the x, y, and z axes. The 3-axis geomagnetic sensor measures the azimuths of the x-axis, y-axis, and z-axis (direction of the geomagnetism).

Hereinafter, a specific operation capability measurement process performed according to various cooking operations according to an embodiment of the present invention, and a configuration added thereto for the operation will be described.

Figure 2 is an exemplary view of performing a pour operation of a liquid stream in accordance with one embodiment of the present invention.

Referring to FIG. 2, according to an embodiment of the present invention, when the operation performed by the user is a pouring operation of the liquid flow, the sensing unit 200 can measure the degree of real-time tilting of the sensing device. The calculation unit 100 may calculate the amount of the liquid poured on the basis of the measured degree of tilt and generate the degree of spread according to the amount of the liquid as an output image. For example, when the user tilts the sensing device such as pouring the liquid in the cup by lifting the sensing device, the amount of liquid poured according to each slope is set as in the actual situation, and if the sensing device is not tilted above a certain slope, Can be prevented from being poured any further. When the user further tilts the sensing device, the calculation unit 100 can generate an output image reflecting the sensed tilt in real time. Thereafter, the screen output unit 300 may display an output image of a degree spreading the liquid generated in real time. As described later, various kinds of motion data other than the degree of inclination of the position on the screen output unit 300 on which the operation is performed can be reflected together with the measurement of the work capacity according to the pouring operation of the liquid flow.

In addition, the calculation unit 100 may further include a figure corresponding to the guide lines 320 and 310 to which the liquid area poured into the output image reaches or is to be aligned. The user attempts to align the liquid area generated through the performance of the work with the guidelines 320 and 310 and the calculation unit 100 calculates the difference between the execution time of the user and the resultant figure and the guide line 320 The user's ability to perform tasks can be evaluated. For example, when the circular liquid region extends from the center of the circular target shape corresponding to the guide lines 320 and 310 according to the operation of the user, the circular shape corresponding to the guide lines 320 and 310 The radius of the circle corresponding to the liquid area can be compared.

Accordingly, the sensing device can measure the rotational acceleration and the number of rotations performed by the patient according to the set degree of difficulty by adjusting the height of the weight 210.

The calculation unit 100 may generate the real-time bubble generation image by applying the degree of bubble generation corresponding to the measured rotation acceleration and the number of rotation. The screen output unit 300 may receive and output the generated image so that the user can confirm the result according to the degree of performance of the user.

FIG. 4B is an exemplary view showing a state after performing a kneading expansion operation according to an embodiment of the present invention. FIG.

In the kneading expansion operation, the first inertial sensor of the sensing unit 200 can recognize the degree of rolling including the rotational acceleration, the rotational speed, the number of rotations, and the like. The calculation unit 100 may expand the dough figure displayed on the screen on the basis of the degree of rolling from the sensing unit 200. [ That is, before the sensing device including the sensing unit 200 passes the area corresponding to the dough, the dough pattern is small (see FIG. 4A), and the dough spreading operation (that is, the sensing device on the screen output unit 300) The rotational motion of the kneading mold is applied to the kneading pattern (see FIG. 4B).

The work performance measuring system 10 may further include a pressure sensor on the screen output unit 300 to measure the kneading expansion operation. The pressure sensor can measure the pressure applied to the screen output unit 300 during the dough spreading operation. That is, the pressure applied to the screen output unit 300 in the course of the pressure sensor moving the sensing unit 200 may be calculated by calculating the pressure applied to the screen output unit 300, such that the degree of spreading of the dough varies depending on the strength of the force applied to the dough in an actual situation. So that it can be reflected in the output image generation of the unit 100.

The calculation unit 100 can generate a guide line 320 (310) of the slicing operation in the output image, and can measure the accuracy by grasping the path of the slicing operation performed by the user.

In addition, the calculation unit 100 may adjust the difficulty level by adjusting the placement intervals of the plurality of guide lines 320 and 310 (that is, the guide lines) by reflecting the work accomplishment time or the accuracy. For example, when the precision of the slicing operation performed by the user along the guideline is higher than a predetermined standard, subsequent guiding lines may be closely arranged to make it difficult to perform the work. In addition, the calculation unit 100 may adjust a time limit for performing a task, and may change a form of a guideline for performing a slicing operation to a form of a higher degree of difficulty.

That is, as the position of the hand moves, the position of the center on the screen output unit 300 where the liquid flow spreads can also be moved. Accordingly, it is possible to determine whether or not the user can maintain a predetermined position for performing the task.

In one embodiment, the screen output unit 300 may include a vision sensor 340, such as a camera, as in FIG.
