Physiological control in games has been studied for some time as a means to replace or augment existing game controllers. Examples of this are sensors such as Heart Beat, Electromyography, Skin Conductance or Respiration sensors. Under the supervision of Professor Rui Rodrigues and PhD student Pedro Alves Nogueira — from the Faculty of Engineering of the University of Porto — my project aimed to propose and implement a prototype with game mechanics relying on multiple physiological inputs from the player.
Below are listed all the published materials regarding my work on biofeedback. These include:
