No matter how immersive games have become, none are able to produce smells to match the on-screen environment - until now. Developer Scent Sciences have demonstrated Scent Scape, a machine that plus in to PCs via a USB port and, with the relevant code written into a game’s software, produces smells appropriate to the environment and action. Price is yet to be announced, but apparently the unit will begin to ship later this year. In the meantime, expect games developers to start tweaking their code to take advantage of the new frontier of olfactory trickery. I don’t think I’ll be rushing out to buy one, but it’s a pretty cool concept.
