Properties of the Acceleration Sensor and Gyroscope Sensor

persist.sensors.mock.delaytime

Data collection frequency, in microseconds

int

[20000,1000000]

200000

If the value of persist.sensors.mock.delaytime is not within the range of [20000, 1000000], the default value is used.

persist.sensors.mock.acce.data.x

• persist.sensors.mock.acce.data.x indicates the acceleration (gravity included, m/s²) along the x-axis.
• persist.sensors.mock.gyro.data.x indicates the rotation rate (radian/second) along the x-axis.

float

[-3.402823466e+38,3.402823466e+38]

Both the default values of the acceleration and gyroscope on the x-axis are 9.833359. You can query the default value using a related application. The default value is not displayed in persist.sensors.mock.acce.data.x or persist.sensors.mock.gyro.data.x. Android 11 quantizes the data collected at the underlying layer together with the resolution value into a new value. The acceleration resolution is 1/4032, and the gyroscope resolution is 1/1000.

If the value of persist.sensors.mock.acce.data.x or persist.sensors.mock.gyro.data.x contains invalid characters that are neither digits nor decimal points, the setting is invalid and the default value is used. Note that a valid float type parameter value contains 6 or 7 digits. If a value is outside the valid range, use the scientific notation, for example, 3.40282e+38. Otherwise, garbled characters are displayed. Due to the type conversion of floating-point data, some upper-layer applications may encounter precision fluctuations even if the value is within the value range.

persist.sensors.mock.acce.data.y

• persist.sensors.mock.acce.data.y indicates the acceleration (gravity included) along the y-axis.
• persist.sensors.mock.gyro.data.y indicates the rotation rate along the y-axis.

float

[-3.402823466e+38,3.402823466e+38]

Both the default values of the acceleration and gyroscope on the y-axis are 0.184357. You can query the default value using a related application. The default value is not displayed in persist.sensors.mock.acce.data.y or persist.sensors.mock.gyro.data.y. Android 11 quantizes the data collected at the underlying layer together with the resolution value into a new value. The acceleration resolution is 1/4032, and the gyroscope resolution is 1/1000.

If the value of persist.sensors.mock.acce.data.y or persist.sensors.mock.gyro.data.y contains invalid characters that are neither digits nor decimal points, the setting is invalid and the default value is used. Note that a valid float type parameter value contains 6 or 7 digits. If a value is outside the valid range, use the scientific notation, for example, 3.40282e+38. Otherwise, garbled characters are displayed. Due to the type conversion of floating-point data, some upper-layer applications may encounter precision fluctuations even if the value is within the value range.

persist.sensors.mock.acce.data.z

• persist.sensors.mock.acce.data.z indicates the acceleration (gravity included) along the z-axis.
• persist.sensors.mock.gyro.data.z indicates the rotation rate along the z-axis.

float

[-3.402823466e+38,3.402823466e+38]

Both the default values of the acceleration and gyroscope on the z-axis are 0.101028. You can query the default value using a related application. The default value is not displayed in persist.sensors.mock.acce.data.z or persist.sensors.mock.gyro.data.z. Android 11 quantizes the data collected at the underlying layer together with the resolution value into a new value. The acceleration resolution is 1/4032, and the gyroscope resolution is 1/1000.

If the value of persist.sensors.mock.acce.data.z or persist.sensors.mock.gyro.data.z contains invalid characters that are neither digits nor decimal points, the setting is invalid and the default value is used. Note that a valid float type parameter value contains 6 or 7 digits. If a value is outside the valid range, use the scientific notation, for example, 3.40282e+38. Otherwise, garbled characters are displayed. Due to the type conversion of floating-point data, some upper-layer applications may encounter precision fluctuations even if the value is within the value range.
