biofeedback – process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will. Some of the processes that can be controlled include brainwaves, muscle tone, skin conductance, heart rate and pain perception. Biofeedback may be used to improve health, performance, and the physiological changes that often occur in conjunction with changes to thoughts, emotions, and behavior.

• smart glasses – electrooculography sensors have been set into the frame of the glasses; above the nose and on the nose pads. They are able to track eye movement and blinking as they track the position of the retina. There is also six axis accelerometers in the ends of the glasses’ arms and these are able to monitor the body’s axis along with walking behaviour.

Uses of biofeedback

• Biofeedback has been found to be effective for the treatment of headaches and migraines.
