It can be seen that the motion information (section 705 to time 706) has significantly increased above the first threshold (eg, 0.1 (702)), and accordingly, it can be confirmed that the user is in an active state in which movement is active. Also in the drawing, referring to the second curve 703 that is heart rate related information calculated based on the sensor signal of the optical sensor 310, for a specified time, for example, several seconds to several minutes or more (eg, from time 705 to time 706 ). section) substantially increased significantly above the second threshold (eg, 1.2 (704)), indicating that both motion information and heart rate-related information have increased, so that it can be confirmed that the state is physically working. It can be seen from the figure that the change patterns of the first curve 701 and the second curve 703 also exhibit similarly increasing and falling patterns. Accordingly, based on the change pattern of the curves in addition to the analysis of each curve, it can be confirmed that the user is in a physical work state in which he is under physical stress while in motion.

According to an embodiment, in the drawing, the first curve 701 that is motion information calculated based on the sensor signal of the motion sensor 320 for the user A in the drawing is after a specific time (eg, a section from time 706 to later). It can be known that the first threshold value (eg, 0.1 (702)) has fallen or less, and accordingly, it can be confirmed that the user is in a resting state in which the movement is stopped. In addition, referring to the second curve 703 , which is heart rate-related information calculated based on the sensor signal of the optical sensor 310 , in the drawing, it substantially decreases after a specific time (eg, a section after time 706 ) to the second threshold value. (Example: 1.2 (704)) or lower, it can be seen that it is a recovery period after a physical work state.

Referring to FIG. 7B , for the user (B), the first curve 711, which is motion information calculated based on the sensor signal of the motion sensor 320, is designated for a specified time, for example, several seconds to several minutes or longer (eg, time).

In addition, referring to the second curve 712 , which is heart rate-related information calculated based on the sensor signal of the optical sensor 310 in the drawing, for a specified time, for example, several seconds to several minutes or more (eg, from time 715 to time 716 ). section) substantially increased significantly above the second threshold (eg, 1.2 (704)), indicating that both motion information and heart rate-related information have increased, so that it can be confirmed that the state is physically working. It can be seen from the figure that the change patterns of the first curve 711 and the second curve 713 also similarly show an increase and a decrease pattern. Accordingly, based on the change pattern of the curves in addition to the analysis of each curve, it can be confirmed that the user is in a physical work state in which he is under physical stress while in motion.

According to an embodiment, in the drawing, the first curve 711 that is motion information calculated based on the sensor signal of the motion sensor 320 for the user B in the drawing is after a specific time (eg, a section from time 716 to later). It can be known that the first threshold value (eg, 0.1 (702)) has fallen or less, and accordingly, it can be confirmed that the user is in a resting state in which the movement is stopped. In addition, referring to the second curve 712 , which is heart rate related information calculated based on the sensor signal of the optical sensor 310 , in the drawing, the second threshold value is substantially decreased after a specific time (eg, a section after time 706 ). (Example: 1.2 (704)) or lower, it can be seen that it is a recovery period after a physical work state.

Looking at the characteristics of the recovery period after physical work of the user (A) of FIG. 7A and the user (B) of FIG. 7B , the recovery time of the user (A) is relatively longer than that of the user (B). long can be seen. According to various embodiments, the processor 120 may calculate the user's physical stress resistance by using a relational expression having a high physical stress resistance when the recovery time is short by cumulatively evaluating the recovery time after the physical work state. have.

According to an embodiment, when there are 50 subjects to measure resistance to physical stress, and their average recovery time is measured to be 90 seconds, the average recovery time may be set to 90 seconds as a reference recovery time for physical work at that time. The physical stress resistance may be calculated, for example, as a value obtained by dividing the reference recovery time by the recovery time of the corresponding user. For example, if the recovery time of user (B) is 60 seconds, the physical stress resistance value may be 90/60=1.5, and if the recovery time of user (A) is 120 seconds, the physical stress resistance value is 90/ It can be calculated as 120=0.75. It can be seen that the physical stress resistance of the user (A) of FIG. 7A is lower than that of the user (B) of FIG. 7B .

Referring to FIG. 8A , for the user (A), a third curve representing the mental stress index, which is the mental work intensity calculated using the heart rate-related information calculated based on the sensor signal of the optical sensor 310 in the mental work state Referring to (801), it can be seen that for a certain period of time (eg, the interval from time 805 to time 808), it substantially increases significantly above the third threshold (eg, 20 (802)), indicating that mental work stress is being experienced. . In particular, in the time interval (eg, the interval from time 806 to time 807), the mental stress index is significantly higher above the fourth threshold (eg, 60 (804)), and in the before and after intervals, the stress index is, for example, the third threshold value The section (a) that increases from the fourth threshold to the third threshold (a) and the section (a) that decreases from the fourth threshold to the third threshold are the section (a) in which the stress index increases after the onset of the mental work state and the stress index after the mental work state, respectively It can be seen that is the section (b) in which is lowered.

According to one embodiment, in the drawing, the longer the section (a) in which the stress index according to the mental work state increases and the section (b) in which the stress index decreases after the mental work state is longer, the lower the ability to resist mental stress, and the shorter these sections are. The higher the score, the better the ability to resist mental stress.

According to an embodiment, the mental stress resistance may be calculated based on the sum of the section (a) in which the stress index increases and the section (b) in which the stress index decreases after the mental work state.

Referring to FIG. 8B , for the user (B), a third curve representing a mental stress index, which is a mental work intensity calculated using heart rate-related information calculated based on a sensor signal of the optical sensor 310 in a mental work state Referring to (811), it can be seen that for a certain period of time (eg, from time 815 to time 818), it substantially increases significantly above the third threshold (eg, 20 (802)), and it can be seen that the person is under mental work stress. . In particular, the time interval (eg, the interval from time 816 to time 817) has a significantly higher mental stress index above the fourth threshold (eg, 60 (804)), and in the anterior and posterior intervals, the stress index is, for example, the third threshold The interval (a) increasing from the fourth threshold to the third threshold and the interval (b) decreasing from the fourth threshold to the third threshold are the interval (a) in which the stress index increases after the onset of the mental work state and the stress index after the mental work state, respectively. It can be seen that is the section (b) in which is lowered.

According to an embodiment, a time (a+b) that is the sum of the period (a) in which the stress index increases and the period (b) in which the stress index decreases after the mental work state is referred to as a recovery time, and mental stress resistance is calculated based on this can do.

According to one embodiment, for example, when there are 50 subjects to measure mental stress resistance, and their average recovery time is measured to be 200 seconds, the reference recovery time for mental tasks at that time can be set to 200 seconds, which is the average recovery time. have. The mental stress resistance may be calculated, for example, as a value obtained by dividing the reference recovery time by the recovery time of the corresponding user. For example, if the recovery time of user (B) is 150 seconds, the physical stress resistance value may be 200/160=1.25, and if the recovery time of user (A) is 250 seconds, the mental stress resistance value is 200/ It can be calculated as 250=0.8. It can be seen that the mental stress resistance of the user (A) of FIG. 8A is lower than that of the user (B) of FIG. 8B .

It can be judged that there is a high possibility of adaptation, and it can be judged that there is a need for management of injuries or overwork until they adapt to work.

According to an embodiment, when the user's average work intensity is high and the stress resistance is low, for example, it can be analyzed as a situation in which a task with high work intensity itself is assigned, and since the user's stress resistance is low, the user's stress resistance is low. It may be judged that the possibility of adaptation is low, replacement or relocation to another job may be recommended, and if this is not possible, it may be determined that continuous careful management is necessary.

According to an embodiment, the first screen 900 may include a first graph 901 indicating the intensity of the physical work of the user A and a second graph 902 indicating the intensity of the mental work. For example, the first graph 901 and the second graph 902 show the average physical work intensity 903 and the average mental work intensity 904, which are the average work intensity during working hours, respectively, and the highest physical work intensity which is the highest work intensity ( 905) and a baseline physical task intensity 907 and a baseline mental task intensity 908 that are the highest mental task intensity 906 and/or baseline task intensity. For example, during a given business hour, user (A)'s average physical workload intensity (903) is 30% and average mental workload intensity (904) is 20%, so that average physical workload intensity (903) is equal to average mental workload intensity (904) It is somewhat higher than that of , but it is lower than the standard physical work intensity (907) and the standard mental work intensity (908), indicating that the work intensity is not high on average. For example, during the corresponding business hours, user (A)'s peak physical task intensity (905) and peak mental task intensity (906) are higher than the baseline physical task intensity (907) and baseline mental task intensity (908), resulting in temporary work intensity It can be seen that there is an increase in , and it can be seen that the distribution of tasks during the time period is not appropriate and the situation is concentrated at a specific time.

For example, the first graph 911 and the second graph 912 are the average physical work intensity 913 and the average mental work intensity 914, which are the average work intensity during working hours, respectively, and the highest physical work intensity which is the highest work intensity ( 915) and the highest mental task intensity (916) and/or baseline physical task intensity (917) and baseline mental task intensity (918), which are baseline task intensity. For example, during a given business hour, user (A)'s average physical workload intensity (913) is 10% and average mental workload intensity (914) is 40%, so that average physical workload intensity (913) is equal to average mental workload intensity (914). Although it is lower than the standard physical work intensity (917) and the standard mental work intensity (918), both are low, indicating that the work intensity is not high on average. For example, during the corresponding business hours, the highest physical work intensity (915) of user (A) is lower than the reference physical work intensity (917), indicating that the physical work intensity is low, but the highest mental work intensity (916) is the reference mental work intensity (916). It is higher than the task intensity (918), so it can be seen that the task intensity is temporarily increased, and it can be seen that the task distribution is unevenly driven during work hours.

According to an embodiment, the third screen 920 may include a first graph 921 indicating the intensity of physical work of the user A and a second graph 922 indicating the intensity of mental work. For example, the first graph 921 and the second graph 922 show the average physical work intensity (923) and the average mental work intensity (924), which are the average work intensity during the working hours, respectively, and the highest physical work intensity ( 925) and baseline physical task intensity (927) and baseline mental task intensity (928), which are peak mental task intensity (926) and/or baseline task intensity. For example, during a given business hour, user (A)'s average physical workload intensity (923) is 20% and average mental workload intensity (924) is 30%, so that average physical workload intensity (923) is equal to average mental workload intensity (924). Although it is somewhat lower than that of , it is lower than the standard physical work intensity (927) and standard mental work intensity (928), indicating that the work intensity is not high on average. For example, during that business hour, user (A)'s peak physical task intensity (925) and peak mental task intensity (926) were lower than baseline physical task intensity (927) and baseline mental task intensity (928), respectively, during that time. It can be seen that the distribution is appropriate.

It can monitor task intensity and provide guidance information such as task allocation, alarms and/or relocation.

According to an embodiment, the third screen 1040 provided by the second electronic device 402 indicates the intensity of the user's mental work for each time period using, for example, a bar graph 1032, so that the user's mind during work hours is displayed. It can monitor task intensity and provide guidance information such as task allocation, alarms and/or relocation.

A second screen 1110 providing information related to the user's work status may be displayed at a first screen 1100 and a second time point 1110 (eg, after 6 hours and 20 minutes after the start of work).

According to an embodiment, the first screen 1100 may include a first graph 1101 indicating the intensity of the user's physical work and a second graph 1102 indicating the intensity of the mental work of the user at the first time point. For example, the first graph 1101 may represent, for example, 25% of the physical work intensity 1103 of the corresponding time point (eg, the first time point), and it may be confirmed that it is lower than the reference physical work intensity 1107. .

According to an embodiment, the second screen 1110 may include a first graph 1111 indicating the intensity of the user's physical work and a second graph 1112 indicating the intensity of the mental task at the second time point. For example, the second graph 1112 may represent, for example, 40% of the mental work intensity 1114 at the time point (eg, the second time point), and it can be confirmed that it is lower than the reference mental work intensity 1118 . .

12 illustrates a first screen 1200 , a second screen 1210 , and a third screen 1220 providing work status related information during the user's work hours.

According to an embodiment, the first screen 1200 includes a first graph 1201 indicating the intensity of physical work of the user, a second graph 1202 indicating the intensity of mental work, and an elapsed time 1209 from the start of the work to the present. can do. For example, the first graph 1201 may indicate that the average physical work intensity 1203 from the start of work to the present is 33%, and it can be seen that this value is lower than the reference physical work intensity 1207 . However, since it is confirmed that the total working hours (1209) from the start of work to the present is 8 hours and 10 minutes, exceeding the recommended time of 8 hours, a notification 1231 indicating that the recommended work time has been exceeded may be provided, and accordingly, the user may induce them to stop working.

According to an embodiment, the second screen 1210 displays a first graph 1211 representing the user's physical work intensity, a second graph 1212 representing the mental work intensity, and an elapsed time 1219 from the start of the work to the present. According to this, it can be seen that 48 minutes have elapsed from the start of the work to the present. For example, in the first graph 1211, it can be seen that the average physical work intensity 1213 of the 48-minute elapsed time from the start of the work to the present is 80%, and this value is higher than the reference physical work intensity 1217 value can be seen. Therefore, although the total work time 1219 from the start of the work to the present is 58 minutes, it is confirmed that the physical work intensity 1213 exceeds the reference intensity, and thus a notification 1232 indicating that the physical work intensity is high may be provided. Accordingly, it may induce the user to stop working or take a break.

According to an embodiment, the third screen 1220 displays a first graph 1221 indicating the intensity of the user's physical work, a second graph 1222 indicating the intensity of mental work, and an elapsed time 1229 from the start of the work to the present. may include For example, the second graph 1222 may represent an elapsed time 1229 since the start of the work, according to which 5 hours and 28 minutes have elapsed since the start of the work, and the average mental work intensity 1224 is 90%. It can be seen that this value is higher than the reference mental task intensity (1228). Thus, the total work hours 1229 from the start of the shift to the present are 5 hours and 28 minutes, but the mental work intensity 1224 is found to be above the baseline intensity, providing a reminder 1233 indicating that the mental work intensity is high, , it may induce the user to stop working or take a break.
