A Virtual System for Balance ControlAssessment at Home

Postural stability is often compromised in many pathological states and decreases with age. In clinical practice, an objective tool for balance control at home is fundamental. Recently, virtual tools, based on the use of depth cameras, have been presented. In this paper, a virtual system for balance control assessment is presented and used to implement a virtual task for balance tracking in real time at home. The usability of the tool is assessed through some experimental data collected by 6 healthy elderly people, that used the system and evaluated it through a questionnaire. Results are reported and discussed.
