AI Technical Summary

Technical Problem

Existing terminal technologies lack effective methods to accurately detect the falling posture before a device touches the ground, which affects the assessment of impact on normal use and fail to optimize design improvements due to insufficient posture data during falls.

Method used

A posture detection method using a first sensor for acceleration data and a second sensor for angular velocity data, where the second sensor is turned on only during a fall event, allowing for efficient data collection within a preset time frame to determine the falling posture accurately.

Benefits of technology

Reduces power consumption by turning off the second sensor when not in use and enhances posture detection accuracy by using data from both sensors to fuse posture data, providing precise falling posture information before ground contact.

Abstract

The present application discloses a posture detection method, terminal and storage medium, which relates to the field of terminal technology and is used to detect the falling posture of the terminal before it falls and touches the ground. The method includes: when the second sensor of the terminal is in an off state, in response to a falling event of the terminal, turning on the second sensor; obtaining the acceleration data collected by the first sensor and the angular velocity data collected by the second sensor within the first preset time after the second sensor is turned on; based on the acceleration data and angular velocity data within the first preset time, determining the posture data of the terminal at each moment within the first preset time; from the posture data at each moment within the first preset time, obtaining the posture data corresponding to the target moment as the falling posture of the terminal.
