Abstract Background People with severe motor impairments often require an alternative access pathway such as a binary switch to communicate and to interact with their environment. A wide range of access pathways have been developed from simple mechanical switches to sophisticated physiological ones. In this manuscript we report the inaugural investigation of infrared thermography as a non-invasive and non-contact access pathway by which individuals with disabilities can interact and perhaps eventually communicate. Methods Our method exploits the local temperature changes associated with mouth opening closing to enable a highly sensitive and specific binary switch. Ten participants two with severe disabilities .
