Multipurpose controllers and methods

A non-transitory computer readable medium comprising one or more programs configured to be executed by one or more processors to enable a user to interact with an electronic device hands-free, said one or more programs causing performance of a method comprising:

• receiving facial expression information (FE information) indicative of performance of a facial expression by the user, said FE information being based on readings from one or more FE sensors coupled to the user's head;
• receiving body information indicative of at least one of motion and position of at least one of head and an eye of the user, said body information being based on readings from one or more body sensors coupled to the user's head;
• detecting said facial expression to be active based on said FE information;
• start generating one or more selection signals when said facial expression is detected to be active;
• stop generating said one or more selection signals when said facial expression is no longer detected to be active;
• and
• generating one or more modification signals, based on said body information, to modify an object of interest affected by the electronic device;
• wherein said one or more selection signals are not the same as said one or more modification signals.
