Accessible Environmental Control Units
Typically, the user of an ECU controls their system using a mobile device or switch, all matched to their physical ability. If a person is not able to physically use a device, speech recognition (think Alexa) and other input methods are also available. These devices are also quite helpful to caregivers, as temperature, lighting, and other aspects of living can all be controlled by the patient or individual. This allows life to continue even if no help is available.
