Touchfoil is a proprietary technology that is designed to turn any large area of glass—a retail display window was their inspiration—into a "huge interactive surface that behaves just like the latest tablet devices." The transparent film can be fitted (or retrofitted) to the inside or underside of any nonmetallic surface to transform it into a touchscreen.
Cambridge, UK-based materials specialists Visualplanet have been refining their flagship product for over a decade now: since the initial release in 2003, "thousands of touchfoils™ have been successfully installed worldwide in public spaces; such as premium brand retail shop windows, office reception areas, bus shelters, street kiosks, tourist information booths and even bathroom mirrors."
Last week saw the launch of their latest product...
We've seen supersized touchscreens before, but Visualplanet continues to innovate with a new version of Touchfoil that features rear-projection film for more versatile digital signage.The latest addition to the single and multi-touch visualplanet touchfoil™ family... can be fitted easily inside exterior windows, or behind interior flat or curved glass panels, to allow interactive media to be touched from the other side of the glass or in the street. It can be used to add interaction to any customer facing situation; shop windows, business reception, exhibitions and museums; indeed any location which would be enhanced by adding an interactive experience.
While Visualplanet is currently focused on commercial—specifically retail—applications of the product, I'd be curious to see what visual artists might do with the material.
