One of the emerging concepts that I’m fascinated and excited by is the Physical Web. If you haven’t heard of this, a brief and very coarse summary is that it’s the idea of transmitting URLs from beacon devices, commonly using low-energy Bluetooth (BLE). Current beacon schemes are largely based on Apple’s iBeacon protocol, which transmits a unique ID that requires an app receiver to decode and turn into an action. The Physical Web’s difference is that URL transmission requires no app, decentralising the process.
Making any device able to transmit a URL is rich with possibilities: from super low-friction discoverability of information about nearby places (imagine a page of search results showing only the things immediately around you), to immediate interaction with nearby physical objects. While I’ve still yet to actually build anything using the Physical Web idea, I’ve started to explore what I think it can be useful for.
