“…Additional context parameters (such as acceleration, orientation, proximity, gesturing, human presence, time, light intensity, sound level, wind direction, weather conditions, and moon phase) comprise alternative modes of implicit input in game projects, often producing immersive game experiences. Some of the abovementioned contextual parameters may be captured by dedicated wireless sensor network installations (Chatzigiannakis et al, 2011); the emergence of robust, programmable, low-cost 802.15.4-compliant sensor node platforms will likely influence the design decisions of pervasive game developers as those could reliably feed a multitude of environmental, social, and activity context data. Likewise, smartphones that commonly integrate GPS receivers, cameras, sensors, compasses and NFC readers are expected to play a significant role in …”
