Abstract 

The TST FB4FD dataset contains data acquired through a pair of smart shoes. The smart shoes are specifically designed for fall detection purposes and are equipped respectively with 3 Force Sensing Resistors (FSRs) and an inertial unit.  More specifically, the dataset consists of 32 different falls and 8 activities of daily living (ADLs) performed by 17 healthy subjects aged between 21 and 55 years, for a total of 544 falls and 136 ADLs sequences .

Instructions: 

TST FB4FD is fully available at the following link: http://www.tlc.dii.univpm.it/blog/footwear-based-dataset-for-fall-detect...

 

The dataset consists in 17 folders,  named with the user ID to which they refer.

Each folder is structured as follow:

  • Acquisitions:

    • ADLs:

      • APBE: Pick up an object on the floor with bending.

        • APBEST: The subject is standing, bends, picks up an object on the floor, and then stands up again.

        • APBEWK: The subject walks, bends, picks up an object on the floor, and then stands up again.

      • APSQ: Pick up an object on the floor with squatting.

        • APSQST: The subject is standing, squats, picks up an object on the floor, and then stands up again.

        • APSQWK: The subject walks, squats, picks up an object on the floor, and then stands up again.

      • ASCH: Sit and get up from the chair.

        • ASCHST: The subject is standing, sits on a chair, and then stands up again.

        • ASCHWK: The subject walks, sits on a chair, and then stands up again.

      • ASSO: Sit and get up from the couch.

        • ASSOST: The subject is standing, sits on a couch, and then stands up again.

        • ASSOWK: The subject walks, sits on a couch, and then stands up again.
