According to an embodiment, the processor 230 may obtain information on the amount of change in the atmospheric pressure data for a predetermined time by using the measured slope information and the peak-to-peak information of the atmospheric pressure data. The processor 230 may obtain acceleration signal vector magnitude (SVM) data from the measured acceleration data, and the acceleration SVM data may include information on the magnitude of the measured 3-axis acceleration data. According to an embodiment, the processor 230 may obtain information on the amount of impact applied to the electronic device 200 using the acceleration SVM data. For example, when the barometric pressure data increases with a steep slope for a predetermined time, it may mean that the height at which the electronic device 200 is located is rapidly lowered, and when the acceleration SVM data instantaneously increases, an impact (or force) may be applied.

According to an embodiment, in operation 450, the processor 230 may determine whether the amount of change in atmospheric pressure data for a predetermined time sensed in operation 430 is greater than a preset threshold, and based on the acceleration data detected in operation 440, the first reference It may be determined whether a first impact greater than or equal to the impact value is detected. According to an embodiment, when the processor 230 detects that the atmospheric pressure data has changed by more than a preset threshold value for a predetermined time and detects a first shock equal to or greater than the first reference shock value from the acceleration data for a predetermined time (450-Yes) , it may be determined that a fall event has occurred in operation 460 .

Referring back to FIG. 3 , the processor 230 according to an embodiment may determine the type of the fall event that has occurred in operation 340 . According to an embodiment, the processor 230 may determine the type of the fall event based on acceleration data and barometric pressure data for a predetermined time used in operation 330, that is, acceleration data and barometric data before and after the fall event occurs. . According to an embodiment, when determining the type of a fall event based on the acceleration data and the barometric pressure data, the processor 230 may use a pattern of predefined sensor data according to the fatality level according to the past accumulated fall history.

When a fall event occurs, the user's injury site and degree of injury may be different depending on whether the user fell forward or backward, or fell while holding hands, as well as the magnitude of the generated shock. Accordingly, the processor 230 according to an exemplary embodiment determines the magnitude of the amount of impact received by the user when a fall event occurs, whether the user fell or fell backward, and the hand It is possible to determine the type of fall event by considering whether or not the person fell while pointing. According to an embodiment, the type of the fall event is a first fall type in which the user is unconscious after the fall event occurs, a second fall type in which the user falls forward, and the user puts his/her hand on the ground (or puts his/her hand on the ground after the user falls backwards). It may include at least one of a third fall type (falling backward while in the air) and a fourth fall type in which the user falls backward while placing his or her hand on the ground. According to an embodiment, the third fall type and the fourth fall type are the same as the type in which the user falls backward, but whether the user touches the ground with his or her hand before (or at the same time) directly falling to the ground while the user falls backward. Alternatively, it may be different whether the body touched the ground with a hand after it fell directly to the ground. Hereinafter, a method of determining a fall event as any one of the first fall type to the fourth fall type will be described with reference to FIG. 5 . However, the type of the fall event is not limited to the first to fourth types described above, and may be divided into more various types or a simpler type according to definition.

5 is a flowchart 500 illustrating a method of determining a fall event type of the electronic device 200 according to an embodiment.

Referring to FIG. 5, operation 340 of FIG. 3 is an operation 502 of determining whether a user's motion is detected for a preset time, an operation 504 of detecting U-axis acceleration data for a predetermined time, and an operation of determining whether the U-axis acceleration data value is An operation of determining whether there is a section in which the atmospheric pressure data is greater than a preset threshold and rising after falling ( 505 ), an operation of analyzing the acceleration data after the first shock ( 507 ), and an impact (eg, a second reference shock value) greater than the second reference shock value and determining whether a second impact) has been detected ( 508 ).

Referring to FIG. 5 , the processor 230 may detect that a fall event has occurred in operation 501 (eg, operation 330 of FIG. 3 ), and a preset time (eg, about 10 seconds) after the fall event occurs in operation 502 . ), it can be determined whether the user's movement is detected. According to an embodiment, the processor 230 may determine whether the user is conscious by detecting whether the user moves based on at least a part of the acceleration data and the barometric pressure data after the fall event occurs. When the user's movement is not detected for more than a preset time (502 - No), in operation 503, the processor 230 may determine the type of the occurred fall event as the first fall type in which the user is unconscious after the fall event occurs. . When the user's movement is detected for a preset time (502 - Yes), in operation 504, the processor 230 determines the opposite direction of gravity from the acceleration data for a predetermined time used in operation 330, that is, the acceleration data before and after the fall event occurs. of acceleration data can be detected. According to an embodiment, the processor 230 may detect the U-axis acceleration data by changing the acceleration data obtained for a predetermined time before and after the fall event into an ENU (east, north, up) coordinate system. According to an embodiment, the U-axis acceleration data may be acceleration data in a direction perpendicular to the ground.

Referring to FIG. 5 , in operation 505 , the processor 230 may determine whether there is a section in which the atmospheric pressure data briefly falls and then abruptly rises during the predetermined time while the U-axis acceleration data has a value greater than a preset threshold. According to an embodiment, when the user falls backward, the electronic device 200 (or the user's hand) may be reflexively and momentarily heard, and accordingly, the atmospheric pressure data value temporarily decreases while the U-axis acceleration data value momentarily decreases. It may have a value greater than the set threshold. Accordingly, when the detected U-axis acceleration data has a value greater than a preset threshold and the section in which the atmospheric pressure data descends and then rises does not exist for the predetermined time period (505 - No), in operation 506, the processor 230 causes a fall The type of event may be determined as a second fall type in which the user falls forward.

According to an embodiment, when the detected U-axis acceleration data has a value greater than a preset threshold and a section in which the atmospheric pressure data descends and then rises exists for the predetermined time period (505 - Yes), the processor 230 performs operation 507 may analyze the acceleration data after the first impact, and in operation 508 it may be determined whether a second impact greater than or equal to a second reference impact value is sensed after the first impact. According to an embodiment, the processor 230 may calculate the amount of impact applied to the electronic device 200 using the acceleration SVM data in operation 508 and determine whether a second impact greater than or equal to a second reference impact value is detected. have. For example, the second impact sensed after the first impact may be an impact received while the user falls backward and the body first falls to the ground and then the hand touches the ground. According to an embodiment, the amount of impact (eg, the amount of the second impact) received while the user's hand touched the ground is the amount of impact (eg, the first impact) received while the user's body (or buttocks, waist) fell to the ground. impact amount of the impact), and the second reference impact value that is the reference value may be smaller than the first reference impact value. According to an embodiment, the second reference impact value may be experimentally calculated like the first reference impact value.

According to an embodiment, when a second shock greater than or equal to the second reference shock value is detected after the first shock (508-Yes), in operation 510, the processor 230 determines the type of the fall event that occurred after the user falls backwards. Straw to the ground can be determined as the third fall type. According to an embodiment, if the second impact greater than the second reference impact value is not detected after the first impact (508-No), in operation 509, the processor 230 determines the type of the fall event that occurred when the user puts his or her hand on the ground. It can be determined as the 4th fall type, in which the person falls backwards while being touched. According to an embodiment, in the third fall type in which the user falls backward without putting his or her hand on the ground (or putting his hand in the air), the first fall type is higher than in the fourth fall type in which the user falls backward while placing his or her hand on the ground. The amount of impact caused by the impact may be large and the degree of injury may be severe.

According to an embodiment, the processor 230 may determine the type of the fall event that has occurred as any one of the first fall type to the fourth fall type, and may fall by continuously sensing the barometric pressure data and the acceleration data even after the fall event occurs. A subsequent continuous operation may be determined. For example, when the user falls forward and rolls, the processor 230 may determine the rolling motion as the secondary motion after the second fall type, and analyze the fall type and the secondary motion together to determine the user's injury site. can

Referring back to FIG. 3 , the processor 230 according to an embodiment may determine an injured part of the user in operation 350 based on the type of the fall event determined in operation 340 . According to an embodiment, information on an injury site and degree of injury expected according to a fall event type may be stored in advance in the electronic device 200 , and in operation 350 , the processor 230 determines the occurrence of the fall from among the previously stored information. It is possible to determine the injured part of the user by using the information corresponding to the type of event. For example, information obtained by analyzing various data related to an injury site and degree of injury occurring according to a fall type may be previously stored in the memory 240 of the electronic device 200 . As another example, information obtained by analyzing various data on an injury site and degree of injury occurring according to a fall type may be stored in advance in an external server. In this case, the electronic device 200 may determine the injured part of the user by using information stored in the external server.

For example, if it is determined in operation 340 that the type of the fall event is the first fall type in which the user is unconscious, in operation 350 the processor 230 may determine that the user's head has been severely injured. As another example, if it is determined in operation 340 that the type of the fall event is the second fall type in which the user fell forward, in operation 350 the processor 230 determines that the user has suffered a strong head injury to the wrist and/or knee. can As another example, if it is determined in operation 340 that the type of the fall event is the third fall type in which the user puts his or her hand on the ground after falling backward, in operation 350 the processor 230 may cause a strong injury to the user's waist and/or hip joint. can be judged to have been As another example, if the type of the fall event is determined in operation 340 as the fourth fall type in which the user falls backward while putting his or her hand on the ground, in operation 350, the processor 230 may reduce the user's back and/or hip joint weakness. It can be judged that he suffered an injury and suffered a strong injury to his wrist. However, the injury site according to the above-described fall type is an example, and in addition, it may be determined in various ways according to the accumulation of injury information.

According to an embodiment, the first fall type may be a case in which the user is unconscious after a fall event occurs, and the second to fourth fall types may be a case in which the user is conscious after a fall event occurs . According to an embodiment, in the case of the first fall type in which the user is not conscious, the need to analyze further barometric pressure data, acceleration SVM data, and/or U-axis direction acceleration data may be low. In this case, on behalf of the unconscious user, the processor 230 may transmit information about the externally generated fall event. For example, the processor 230 may send a rescue request to the emergency services.

Hereinafter, changes in atmospheric pressure data, acceleration SVM data, and U-axis direction acceleration data in the second to fourth fall types will be described in detail with reference to the accompanying drawings.

Referring to the graph (b) of FIG. 7 , after ^{a high peak 720 of about 400 mm/s 2} occurs in the acceleration SVM data, a low peak 730 of about 200 mm/s ^{2 occurs} that can be checked The high peak 720 part of the acceleration SVM data may mean the first impact received from the user's buttocks, and the low peak 730 part of the acceleration SVM data is generated when the hand touches the ground after the first impact occurs. It may mean a second impact. Referring to the graph (c) of FIG. 7 , when a fall event of the third fall type occurs, most of the acceleration data in the U-axis direction has a negative (-) value, but as the user's body is lifted, the amount temporarily exceeds a certain threshold.

Referring to the graph (b) of FIG. 8 , it can be confirmed that a high peak 820 occurs in the acceleration SVM data, and since the user's hand and body simultaneously touch the ground, a peak does not occur after the high peak occurs. can confirm that it is not. Referring to the graph (c) of FIG. 8 , when a fall event of the fourth fall type occurs, most of the acceleration data in the U-axis direction has a negative (-) value, but as the user's body is lifted, the amount temporarily exceeds a certain threshold. It can be seen that the (+) value (830) is shown.

According to an embodiment, the processor 230 may acquire acceleration data and barometric pressure data in operation 901 , determine the user's walking situation in operation 902 , and detect a change in atmospheric pressure data for a predetermined time in operation 903 . In operation 904 , a change in acceleration data may be detected for a predetermined time. The processor 230 according to an embodiment may determine whether an amount of change of the atmospheric pressure data is greater than a preset threshold value and an impact (eg, a first impact) greater than a first reference impact value is detected in operation 905 , the condition of operation 905 is satisfied (905-Yes), it may be determined that a fall event has occurred in operation 906 . The processor 230 according to an embodiment may determine the type of the fall event that has occurred in operation 907 , and may determine an injured part of the user in operation 908 .

If it is determined that the condition is not satisfied in operation 905 (905 - NO), the processor 230 according to an embodiment determines whether the amount of change in the atmospheric pressure data is greater than a preset threshold value and the third reference shock value or more in operation 909. It may be determined whether an impact (eg, a third impact) having an intensity lower than a reference impact value is detected. When the condition of operation 909 is satisfied (909-Yes), the processor 230 may store information on the sensed shock in operation 910 in the memory 240 , and the shock accumulated in the memory 240 in operation 911 It may be determined whether the number of is greater than a preset threshold. When the condition of operation 911 is satisfied (911-Yes), the processor 230 may determine whether the sum of the shock amounts accumulated in the memory 240 in operation 912 is greater than a threshold value based on a preset user tendency. . When the condition of operation 912 is satisfied, the processor 230 may determine an injured part of the user according to the accumulated impact in operation 913 .

Operations 901 to 908 of FIG. 9 describe a method of determining a user's injured part due to the currently occurring fall event itself, and operations 909 to 913 indicate that the impact caused by the currently occurring fall event is not strong enough to cause an injury, but weak impacts are applied. It may be a description of a method for determining an injury site that may be accumulated.

Operation 901 of FIG. 9 may correspond to

operations

310 and 320 of FIG. 3 , operations 902 to 906 of FIG. 9 may correspond to operation 330 of FIG. 3 , and operation 907 of FIG. 9 may correspond to operations of FIG. 3 . may correspond to 340 , and operation 908 of FIG. 9 may correspond to operation 350 of FIG. 3 .

According to an embodiment, when the amount of change of the atmospheric pressure data is greater than a preset threshold and a third shock is detected from the acceleration data, which is smaller than the first reference shock value but greater than the third reference shock value, the user falls and receives a weak shock. can mean In this case, in operation 910 , the processor 230 may store the history information on the sensed impact in the memory 240 to cumulatively manage it. According to an embodiment, when the processor 230 stores the history information for the third impact in the memory 240 , it may divide and store the falling type or store the impact site information according to the type together. For example, the processor 230 may divide and store the fall type due to the third impact using the method of operations 504 to 510 of FIG. History information about the sensed impact may be stored in the memory 240 by dividing it into a type in which the user puts their hand on the ground after falling, and a type in which the user falls backward while putting their hand on the ground.

According to an embodiment, the processor 230 determines whether the number of shocks accumulated in the memory 240 in operation 911 is greater than a preset threshold, and in operation 912 the shocks accumulated in the memory 240 It may be determined whether the sum of the amounts is greater than a preset threshold value based on the user tendency. According to an embodiment, when both the conditions of

operations

911 and 912 are satisfied, the processor 230 performs an operation 913 according to the accumulated shock based on the information on the impact for each type of fall accumulated and stored in the memory 240 . It is possible to determine the injured part of the user. According to an embodiment, operation 911 may be omitted.

According to an embodiment, the threshold value based on the user tendency may be preset based on the user's profile information and the user's daily life pattern. For example, the user's profile information may include at least one of the user's age information, gender information, height information, weight information, and blood type information, and the daily life pattern may include information about the user's usual activity. . According to an embodiment, even if the same shock is received, the degree of injury may be different depending on the user's propensity, and in consideration of this, a threshold value based on different user propensity may be set for each user. For example, active users may be less prone to fall-impact injuries than inactive users, women may be more vulnerable to fall-impact injuries than men, and fall due to lower bone density and less muscle mass as they age. Injuries from impact can be severe. The information used to obtain the threshold value based on the above-described user tendency is an example, and the present invention is not limited thereto, and various information about the user may be used.

According to an embodiment, each of m', s', and a' values obtained by normalizing the active movement duration m, gender s, and age a values within a group are obtained, and these values We can calculate the value of the activity coefficient c by applying a weight to . The above-described formula for calculating the value of the activity coefficient c is an example, and in addition, various information about the user may be further reflected to obtain the activity coefficient c.
