Using technology similar to that found in a lie detector, Corey McCall, a Stanford University doctoral candidate, is creating a video game controller that registers signals about a players respiration, pulse, and perspiration. In Gregory Kovacs\u2019s lab, in association with Texas Instruments, a prototype was constructed.<\/p>\n
As a player gets more excited, all of signals the device registers change. Consider physical activity or watching an interesting movie, surprising these have similar autonomous nervous responses. As your interest or involvement increases your respiration rate decreases, pulse increases, and perspiration increases.

\nThis data is then used to synthesize whether the player is bored or perhaps over involved in the game. This can be then used to modify the gaming experience to either add more intensity and difficult if the player is bored or tone down the\u00a0gameplay a child player is too excited.<\/p>\n
\u201cIf a player wants maximum engagement and excitement, we can measure when they are getting bored and, for example, introduce more zombies into the level,\u201d McCall said. \u201cWe can also control the game for children. If parents are concerned that their children are getting too wrapped up in the game, we can tone it down or remind them that it\u2019s time for a healthy break\u201d (Kurzweil).<\/p>\n
By reading the physiological signals, McCall takes advantage of monitoring the autonomous nervous system, instead of wiring right into someone\u2019s brain, to read\u00a0 one\u2019s emotions. \u00a0Reading the autonomous nervous system response is much less invasive, as the actual prototype plays and feels extremely similar to a normal Xbox controller. A more invasive technique would require the player to wear an EEG cap, which could become distracting.<\/p>\n
