1. A system for assessing functional performance of an individual based on an analysis of a process of sitting down and standing up performed by the individual, the system comprising:
a sensor device, wherein the sensor device is a distributed pressure sensor, wherein the sensor device comprises an array of sensors of Nr×Nc that produces a Nr×Nc measurement matrix for each sampling time;
a monitoring system, connectable to the sensor device, configured to:
receive signals coming from the sensor device, wherein received signals are in the form of a tri-dimensional tensor TS of order Nr×Nc×NS, where Nr is a number of rows of array of sensors, Nc is the number of columns of array of sensors, and NS is a number of sampling times;
pre-process the signals received from the sensor device, wherein pre-processing, by the monitoring system, the signals received from the sensor device comprises:
producing, by the monitoring system, an equi-order tensor TMAX of dimensions Nr×Nc×NMAX;
vectoring the produced equi-order tensor TMAX into a vector V of length NMAX, in which to each position i in is assigned a sum of the elements of the Nr×Nc measurement matrix in a position i of the tensor TMAX;

extract main features of the pre-processed signals as extracted predictor variables; and
assess the functional performance of an individual based on the extracted predictor variables.
