Temperature for human-computer interaction

The temperature difference isn't largeless than 10 degrees heating or cooling after five seconds.

Technology Review

Touch interfaces and haptic feedback are already a part of how we interact with computers, in the form of iPads, rumbling video game controllers and even three-dimensional joysticks. As the range of interactions with digital environments expands, it's logical to ask what's next: Smell-o-vision has been on the horizon for something like 50 years, but there's a dark horse stalking this race: thermoelectrics.

Based on the Peltier effect, these solid-state devices are easy to incorporate into objects of reasonable size, i.e. video game controllers.

In this configuration, announced at the 2010 SIGGRAPH conference, a pair of thermoelectric surfaces on either side of a controller rapidly heat up or cool down in order to simulate appropriate conditions in a virtual environment.
