1. IntroductionAs human beings, we have a multitude of senses that provide us with information about our immediate surroundings. Our sight, hearing and touch primarily define how we perceive our environment and understand the world [1]. Hundreds of thousands of years of evolution have taught us to use the information gathered by our senses to communicate ideas effectively with each other and respond appropriately. Therefore, when people interact, they can use inherent situational information to increase the flow of the conversation. This information is often called context [2]. On the contrary, human-machine communication lacks this transmission of ideas since the computer does not have the same perception as a human being. The infusion of implicit data into human-computer interaction is therefore essential for the implementation of more useful IT services [2, 3]. In the early 1990s, pervasive computing researchers at Xerox PARC brought about a change in thinking. They suggested that context could act as a means of system adaptation [4]. In 1994, Bill Schilit coined the term "contextual computing" [5] to characterize systems capable of detecting and responding to a variety of situational stimuli. At the time, context was primarily limited to location, but over the years many authors debate that “context is not limited to location” [6, p.893]. The importance of context has gradually increased over the last two decades due to the gradual permeation of computers into our lives. Therefore, context awareness has been an important topic for research on mobile and ubiquitous systems for many years [7]. The mobile device is undoubtedly a determining factor in the progress of knowledge of the mobile context. Its universality coupled with the increase in...... middle of paper ......artphone-based context provider for location-based services,” Pervasive Computing, IEEE, vol. 10, no. 2, pp. 58-67, April 2011.[17] V.
