In early October, Google announced a new project called ” The Physical Web,” which they explain like this:
The Physical Web is an approach to unleash the core superpower of the web: interaction on demand. People should be able to walk up to any smart device – a vending machine, a poster, a toy, a bus stop, a rental car – and not have to download an app first. Everything should be just a tap away.
At the moment this is an experimental project which is designed to promote establishing an open standard by which this mechanism could work. The two key elements of this initiative are:
URLs: The project proposes that all ‘smart devices’ should advertise a URL by which you can interact with that device. The device broadcasts its URL to anyone in the vicinity, who can detect it via their smartphone (with the eventual goal being this functionality is built into the smart phone operating systems rather than needing third-party apps).
Beacons: Not well known until Apple recently jumped on the bandwagon announcing iBeacons, beacon technology has been around for a couple of years now. Using a streamlined sibling of Bluetooth, called Bluetooth Low Energy (no pairing, range of ~70 metres / ~230 feet) it allows smartphones to detect the presence of nearby beacons and their approximate distance. Until now they’ve mostly been used to ‘hyper-local’ location based applications (check this blog post of mine for some thoughts on how this might impact SEO).
