Patent Shows How Wii Vitality Sensor Works
A found patent application explains how people will soon be able to play games by breathing.
Siliconera stumbled upon a patent application filed by Nintendo showing how their previously announced Vitality Sensor works and what kinds of games will use it.
The sensor clips onto the end of a person's finger and uses a light source in the top and a light sensor in the bottom to measure the concentration of hemoglobin in the person's finger. The more stressed a person is, the more hemoglobin will be detected. It can also measure a person's breathing rate.
The patent application explains how this system can be used in a game. Players tilt the remote up and down to move a little smiling blob with a hat who's moving through a corridor with a ceiling that rises and falls. As the blob moves down the corridor, its hat goes up and down with the player's breathing. The point of the game is to create a relaxed breathing pattern for the player.
Before and after, the Vitality Sensor will measure the player's "relax fluid" to show how much their stress level has fallen after playing the game. The blob game could be a part of Wii Relax, which was trademarked by Nintendo last year.
