• Resumen

  • As the number of individuals without physical access to communication or environtnental interaction escalates, there are increasing efforts to uncover novel and unconventional access pathways. In this chapter we introduce three emerging access technologies for individuals with severe disabilities: near infrared spectroscopy, electroencephalographic measurement of visually-evoked potentials and infrared thermographic imaging of the face. The first two technologies harness activity directly from the brain while the third exploits spontaneous temperature changes in the face. For each technology, we discuss the physiological underpinnings, the requisite instrumentation, the scientific evidence to date and the future outlook.
