Adapting technologies to model contexts: Two approaches through RFID & NFC

The adaptability of sensorial capabilities is crucial for the performing of daily activities in intelligent environments. There are a number of features that have to be considered, however, in order to avoid constraints of certain technologies. In this work we analyze model and interaction changes using Radiofrequency Identification (RFID) and Near Field Communication (NFC) technologies. When these kinds of technologies are adapted in an attempt to put proactive systems into practice, context-aware applications can suffer some changes; the interaction involved also undergoes changes.
