Now, a psychology researcher with the Twitch username “Perrikaryal” has taken the concept of head control a step further by playing and streaming various TV and computer games using only her head and eye movements in combination with so-called electroencephalography (EEG) on her scalp.
“Perri”, as she is also called, has tested this experiment in various games such as Halo, Elden Ring, Trackmania, and Valorant (shown in the picture). She has also experimented with and tested singing as well as thought control. She controls her movement in the game through head and eye movements while she fires weapons and the like in the games through electrodes placed on the head, writes Swedish online computer magazine Sweclockers.
– The ultimate goal is to make hands-free control complete (all buttons and joysticks) and easier than a regular hand controller, so that anyone can use it for a comparable gaming experience, she says.
Only a small percentage of the population is so physically disabled that they cannot use their hands at all and would benefit from playing games only with head movements.
If techniques for eye tracking and thought reading become sufficiently advanced, it could potentially give players an advantage over those who use more traditional pointing and input devices and could provide ergonomic relief for shoulders and wrists. At the same time, these techniques may have downsides in the form of other fatigue symptoms or side effects.
