| Human factors related context is structured into three categories: information on the user (knowledge of habits, emotional state, biophysiological conditions), the user's social environment (co-location of others, social interaction, group dynamics), and the user's tasks (spontaneous activity, engaged tasks, general goals). Likewise, context related to physical environment is structured into three categories: location (absolute position, relative position, [[wikt:colocation|co-location]]), infrastructure (surrounding resources for computation, communication, task performance), and physical conditions (noise, light, pressure, air quality).<ref>[https://link.springer.com/article/10.1007%2Fs11042-010-0711-z?LI=true A Comprehensive Framework for Context-Aware Communication Systems.
