London: `Smell-O-Vision` is a plug-in device for computer games that emits a variety of odours, depending on the scenario.
If your character is crawling around the jungle, it whiffs out the unmistakable smell of pine.
Should you find yourself at sea, the smell of the water will be instantly delivered by the `personal scent delivery system`.
The ScentScape has around 20 pre-loaded smells and is programmed to respond to exactly what is happening on screen, the Daily Mail reports.
But its makers hope that the in-built editing application will allow gamers to make their own scents and share them with other users.
The $69.99 device from California-based Scent Sciences has a `volume control` feature to ensure you are not overwhelmed by the fumes.
Additional `smell cartridges` such as holiday and summer mean it will also be possible to add smells to home videos. Other cartridges could be created for aromatherapy and other applications.
"ScentScape is an innovative digital scent delivery system, which provides extra dimension of scent to gaming, entertainment and other consumer markets," Scent Sciences says on its website.
"Simply connect the Plug-N-Play unit to any compatible PC or gaming console for an instant experience of sight, sound and smell."
Technicians have for years tried to find a way to combine smell with vision, often with ridiculous consequences.
