Abstract
Temporally segmenting an instrumented gesture executed by a user with a terminal having an inertial navigation module, which measures a vector of inertial characteristics representative of movement of the terminal. Segmenting includes, at each current instant: calculating an instantaneous power value of the vector; estimating a gesture indicator based on variation between the instantaneous power value and a mean power value estimated over a preceding time window; determining a start of gesture at a first instant, when the estimated gesture indicator is greater than or equal to a first threshold during a time interval greater than or equal to a first interval; and determining an end of gesture at a second instant when, at the current instant, the estimated gesture indicator is less than or equal to a second threshold during a time interval greater than or equal to a second time interval.
