This work analyses the use of NFC technology to simplify the interactions of users with context-aware services offered by intelligent environments. Touch Computing is a novel explicit user interaction mechanism in which users accompanied by their NFC-enabled mobile devices request services from the environment by touching tags or other NFC-enabled devices. This paper describes the deployment of three NFC-aware services within SmartLab, our AmIdedicated lab, and the user experience derived from them. Moreover, it analyses the possibilities offered by the current state of the art on NFC and suggests some future lines of work, which may revert into its more widespread deployment in the near future.
