The Ubiquitous Web Applications Working Group seeks to simplify the creation of distributed Web applications involving a wide diversity of devices, including desktop computers, office equipment, home media appliances, mobile devices (phones), physical sensors and effectors (including RFID and barcodes). This will be achieved by building upon existing work on device independent authoring and delivery contexts by the former DIWG, together with new work on remote eventing, device coordination and intent-based events.
