Touchscreens are omnipresent, a multitude of devices and screen formats exist with thousands of apps, however, we only found a few options that enable object interaction.

We were interested in finding ways to get our flat screens to interact with physical 3d objects and surfaces.

We can imagine a lot of creative opportunities to bridge these two worlds – objects and materials you can touch with digital applications able to display rich interactive content.
