Sensor-aware web interface

Traditionally, human machine interactions (HMI) occur in the form of simple, typically single flows of uniform events, such as mouse clicks on Graphical User Interface (GUI). Researchers in the HMI field aim to improve the HMI experience using a more natural approach. Interaction infrastructure is becoming more pervasive, and terminal devices are increasingly equipped with multiple sensors, such as video cameras or audio/video equipment, capable of collecting information from the environment. Video sensors are already placed in nearly every kind of device with which humans interact, such as PCs, mobile phones, and PDAs. In this paper, we propose that in Web 2.0-3.0, the interactive experience could be greatly improved from the client point of view with the use of a pervasive computing paradigm. We focus our attention on improvements that can be obtained with video sensors, and describe a more general architecture that is compliant with the current web infrastructure.
