Abstract
Disclosed are a system, a method, and a program for initializing an attachment location of a measurement sensor. The method of initializing an attachment location of at least one measurement sensor includes requesting selection of the measurement sensor that is attached to a specific body unit (S100); recognizing identification information of the measurement sensor, which agrees with a selection manipulation of the measurement sensor (S200); matching the identification information with the body unit (S300); and determining sensing data received from the measurement sensor, which corresponds to the identification information, as motion data of the body unit. According to the inventive concept, because attachment locations of a plurality of measurement sensors are initialized, a terminal may accurately calculate a posture or motion of the user.
Core Innovation
A terminal performs a method of determining an initial attachment location of at least one measurement sensor configured to be attached to a particular location of a body of a user. The terminal requests a user selection input for the at least one measurement sensor, retrieves identification information of the at least one measurement sensor selected according to the selection input, and matches the retrieved identification information with the particular location of the body to determine the initial attachment location.
After the at least one measurement sensor is attached to the body of the user, the terminal acquires sensing data received from the at least one measurement sensor, where the sensing data corresponds to the identification information, as motion data of the particular location of the body of the user. The disclosure also includes retrieval via a sensor hub based on the selection input over wireless communication, interactive selection of location options for a body and measurement-sensor options configured to attach to the selected location, and matching by dividing a specified body location into a plurality of detailed locations or by receiving touch-screen designation input to designate a detailed point of the body.
In addition, the method includes verification and corrective handling by requesting reference motions or postures and determining normality using expected sensing ranges, and identifying erroneous attachments when the whole body motion or posture does not match normal motion or normal body posture. When erroneous locations are identified, a pair of erroneous locations of the body and corresponding erroneous sensor attachment locations are determined, and the method requests the user to exchange those sensor locations to correct attachment.
Claims Coverage
The independent claim coverage consists of a terminal-executed method for determining an initial attachment location and acquiring motion data, and a non-transitory computer-readable medium storing a program that executes the same method. Across the disclosed claim set, the main inventive features include user selection for sensor attachment location determination, identification retrieval and matching of sensor identification to a body location, and acquisition of sensing data mapped to that body location as motion data, with refinements for hub-based wireless retrieval, interactive body-location and sensor selection, detailed location subdivision or touch-screen detailed point designation, and verification with erroneous attachment detection and corrective exchange requests.
User selection for initial sensor attachment location determination
Requesting, by the terminal, to a user, a selection input for the at least one measurement sensor that is configured to be attached to a particular location of a body of the user.
Sensor identification retrieval and matching to body location
Retrieving, by the terminal, identification information of the at least one measurement sensor, which is selected according to the selection input; matching, by the terminal, the retrieved identification information with the particular location of the body where the at least one measurement sensor is configured to be attached so that the initial attachment location of the at least one measurement sensor is determined.
Acquiring motion data from sensing data mapped to the initial attachment location
Acquiring, by the terminal, after the at least one measurement sensor is attached to the body of the user, based on the determined initial attachment location, sensing data received from the at least one measurement sensor, which corresponds to the identification information, as motion data of the particular location of the body of the user.
Program for terminal-executed initial attachment location determination and motion data acquisition
A non-transitory computer-readable recording medium in which a program for determining an initial attachment location of a measurement sensor, which is coupled to a terminal that is a hardware, the program includes instructions to execute a method comprising requesting a user selection input, retrieving identification information selected according to the selection input, matching the retrieved identification information with the particular location of the body to determine the initial attachment location, and acquiring sensing data received from the attached measurement sensor as motion data of the particular location based on the determined initial attachment location.
Hub-based wireless retrieval of selected sensor identification information
Retrieving identification information of the at least one measurement sensor via a sensor hub based on the selection input, where the sensor hub identifies the selected measurement sensor among multiple measurement sensors, retrieves that sensor’s identification information, and transmits it to the terminal over wireless communication.
Interactive selection of body location and measurement sensor option
Outputting location options for a body, receiving a user's selected location, outputting measurement-sensor options configured to attach to the selected location, and receiving a user's selection of at least one measurement sensor.
Dividing a body location into detailed locations for matching
Dividing a specified body location into multiple detailed locations using a terminal based on the number of measurement sensors to be attached to that location.
Touch-screen designation and display of a detailed body point
Requesting a user to enter, via a terminal touch screen, a detailed location designation of a body point, receiving that designation input, and displaying the detailed point on the touch screen.
Whole-body normality check and erroneous attachment identification
Determining when whole body motion or posture does not match normal motion or normal body posture, identifying erroneous sensor attachment locations, calculating a pair of erroneous locations, and requesting the user to exchange those sensor locations.
Overall, the claim set centers on determining an initial attachment location by matching sensor identification information selected by the user to a particular body location, and then acquiring sensing data corresponding to that identification as motion data for the body location. The disclosed refinements extend this core workflow with hub-based wireless identification retrieval, interactive two-stage location/sensor selection, detailed location subdivision or touch-screen detailed point designation, and verification that detects erroneous attachments and requests sensor location exchange.
Stated Advantages
Accurate whole body posture/motion calculation by acquiring sensing data as motion data of the particular location based on the determined initial attachment location.
Double-checking attachment correctness by determining whether whole body motion or posture matches normal motion or normal body posture and identifying erroneous attachment locations.
Improved measurement accuracy by determining detailed attachment points using reference postures or touch-screen designation.
