On the other hand, when a user wearing the wearable device 100 moves to a low place, the surrounding air pressure may increase and the altitude sensor 526 may obtain a lower altitude value accordingly. If the change in the measured altitude value is greater than or equal to a threshold, the processor of the wearable device 100 may determine that the first sensor data satisfies the condition, and the processor of the wearable device 100 may be affected by a shock (for example, a shock due to a fall accident). ) can be determined to have occurred and the sensor data storage mode can be activated.
