The Physical Web: walk up and use anything


READ ME

The Physical Web

The Physical Web is not shipping yet nor is it a Google product. This is an early-stage experimental project and we're developing it out in the open as we do all things related to the web. This should only be of interest to developers looking to test out this feature and provide us feedback.

The Physical Web is an effort to extend the core superpower of the web - the URL - to everyday physical objects. Our core premise is that you should be able to walk up to any “smart” physical object (e.g. a vending machine, a poster, a toy, a bus stop, a rental car) and interact with it without first downloading an app. The user experience of smart objects should be much like links in a web browser: i.e., just tap and use.

At its base, the Physical Web is a discovery service: a smart object broadcasts relevant URLs that any nearby device can receive. This simple capability can unlock exciting new ways to interact with the Web.

Introduction to the Physical Web

Build Status

Why URLs?

The URL is the fundamental building block of the web, giving remarkable flexibility of expression. It can be:

  • a web page with just a tiny paragraph of info
  • a fully interactive web page
  • a deep link into a native application

Why We're Doing This

The number of smart objects is going to explode, both in our homes and in public spaces. Much like the web, there is going to be a long tail of interactivity for smart objects. But the overhead of installing an app for each one just doesn’t scale. We need a system that lets you walk up and use a device with just a tap. The Physical Web isn’t about replacing native apps; it’s about allowing interaction for the times when native apps just aren’t practical.

Open Design

The Physical Web must be an open standard that everyone can use. This can’t be a product that is locked down by a single company. Like many web specifications, this is an open source design that is being released early so everyone can experiment and comment on it. There is much to discuss and add to this specification.
