2.1

Tilt detection

The tilt function helps to detect activity change and has been implemented in hardware using only the

accelerometer to achieve targets of both ultra-low power consumption and robustness during the short duration of

dynamic accelerations.

The tilt function is based on a trigger of an event each time the device's tilt changes and can be used with

different scenarios, for example:

Triggers when phone is in a front pants pocket and the user goes from sitting to standing or standing to

sitting;

Doesn’t trigger when phone is in a front pants pocket and the user is walking, running or going upstairs.

2.2

Significant Motion Detection

The Significant Motion Detection (SMD) function generates an interrupt when a ‘significant motion’, that could be

due to a change in user location, is detected. In the LSM6DSO32X device this function has been implemented in

hardware using only the accelerometer.

SMD functionality can be used in location-based applications in order to receive a notification indicating when the

user is changing location.

2.3

Finite State Machine

The LSM6DSO32X can be configured to generate interrupt signals activated by user-defined motion patterns. To

do this, up to 16 embedded finite state machines can be programmed independently for motion detection such as

glance gestures, absolute wrist tilt, shake and double-shake detection.
