Adding Temperature to Human-Computer Interaction

Researchers are working on a controller that gets hot or cold depending on what is happening in the game. Kinda neat seeing a couple old peltiers being used for something like this.

The temperature difference isn't large - less than 10 degrees heating or cooling after five seconds, but the researchers involved discovered that, as with haptics, just a little sensory nudge can be enough to convince involved participants in a virtual environment that they are experiencing something like the real thing.
