USB olfactory stick with software integration
One way to extend the reach of the computer hardware is to stimulate some of the remaining senses that are yet to be exploited. For example the olfactory sense doesn't really get much attention at the moment and I think it is a great opportunity particularly in simulation and gaming. The system I am thinking about is an adapted USB device that is pre-loaded with a number of different scents. The USB device heats and diffuses these scents when notified by a software application or game. A few examples when this technology would increase the richness of the user experience are: Burning rubber scent during car racing games, environmental scents during gameplay, scents during online shopping, branded scents during advertising, new product scents when advertising, any time something online wants to be associated with a pleasant scent.
