There are already plenty of exciting augmented reality solutions available for you to take advantage of. Thermal Touch is a fascinating idea though. It turns any surface into a touchscreen. It accomplishes that with an infrared and standard camera working in tandem to register the heat signature left by a person’s finger when touching a surface. Metaio’s AR software makes it possible for the user to interact with digital content in a tactile way.
Solutions like this can always be improved upon. Think about all the possibilities though. There is a lot to like about Thermal Touch.
