Some video games really get your heart racing. Now, game makers are building interactive games that tap into a person's physiological reactions and incorporate them into the play.
Such games are not just meant to entertain, but to give players heightened awareness of their own physical health and to train them to improve mental, emotional or physical well-being.

In other words, keeping calm can really rack up the high scores.
With many of these games, players wear a headset, such as the Neurosky (above), which picks up signals from the brain. Such a device links with a game, which provides scenarios based on the wearer's brain activity.
For example, with the game Mindlight, developed by GainPlay Studio, a child wears a brainwave-sensing headset and then moves her character through a haunted world filled with scary images.
The game's character is also wearing a headset, except this one has a light meant to illuminate dark passageways. As the animated character walks through the various rooms of a haunted mansion, she solves puzzles and defeats creatures. By staying calm, the light shines brightly; but if the child becomes fearful or anxious, the light dims.
After time, the child learns to adjust their mood and calm their anxieties.
