Controllers designed to allow diabled patients to remotely control a variety of equipment usually in the individual\'s immediate environment, which are activated using voice commands. These controllers are typically electronic units that may be customized to the particular user\'s pronunciation; the control unit interacts (e.g., using radiofrequency or infrared energy) with receiving devices interfaced with appliances such as light switches, appliances (e.g., television sets, VCRs, CD players), and bed and door controls; the controller typically includes a built-in telephone set. Voice-activated disabled-patient-assistance controllers are intended to help people with different degrees of disability perform daily activities with a high degree of independence.
