Virtual object handling to assist people with limited mobility

Interaction with appliances present in an environment can be difficult for people who have mobility problems (such as the elderly or moving out of a wheelchair). This paper presents an approach based on the use of an Inertial Measurement Unit which identifies human movements from two points of view: on the one hand, the user can specify the object with which it wants to interact by simply pointing it with his arm, from the other he can pass a command to the object indicated by an appropriate gesture of the arm. The paper describes the operating modes of the approach, the Hw/Sw architecture used and the underlying mathematical analysis.
