Using in-built RFID/NFC, cameras, and 3D accelerometers as mobile phone sensors

Abstract

One of the limiting factors in mobile applications development is the restrictions imposed on the user interface through reliance on the standard ITU-T keyboard which is only really optimal for dialling phone numbers. However, with the convergence of the mobile phone with other sensing technologies, such as Radio Frequency Identi.cation (RFID) and the associated Near Field Communications (NFC), Cameras, and 3D motion sensors, we have the opportunity to use new relational interfaces [12] based on touch, vision, and movement to create new and exciting experiences for mobile application users. In this chapter we present the technologies and the software Application Program Interfaces (APIs) associated with these sensors together with methodologies for their use. © 2007 Springer.
