Context in Mobile Computing
In recent decades, there have been rapid advances in mobile computing, such as context awareness, integrated sensor technologies and a wide range of wired and wireless practices. Most of the modern mobile computing systems can use context to provide appropriate information and services to the user, where relevance depends on the user's task (Zheng et al., 2016). The purpose of having mobile computing systems that are context-aware is to offer the various services at a reasonable development cost and with simple reconfiguration. That being said, it is important to discuss context awareness in mobile computing. This paper will discuss context as it applies to mobile computing and the various ways in which context has been used. Besides, the paper will describe sensor fusion as it applies to context and suggests new ways of using context.
Context as it applies to Mobile Computing
The concept of context has been explored by a number of researchers. Musumba and Nyongesa (2013) argue that context encompasses location, characteristics of neighboring users or objects and the consequent changes. Talipov et al. (2015) refer to context as location, environment attributes, time and the identities of neighboring users. According to Riboni (2015), context involves the user's feelings, concentration, location, date and time, and the objects in the user's environment. Based on these definitions, it is notable that the most important aspects of context are user location, the user's environment, and the objects near the user. Additionally, it can be said that context is subject to the constantly shifting execution environment. Even though the notion of context comprises the understandings of a scenario, much of the effort within the mobile computing community takes a bottom-up methodology to context.
In mobile computing, context involves the understanding of the physical environment and how the implicit input influences the behavior of an application. It encompasses three forms of the environment – computing environment, user environment and the physical environment (Vinh & Suzuki, 2013). Through the concept of context, these environments are able to interact constantly. The information in the computing and physical environments of mobile devices generates a context for interaction between users and devices. Since the current mobile devices process a wide range of data, context help in controlling the ways users interact with the ubiquitous environment based on their repetitive tasks (Zheng et al., 2016). For instance, a context-aware mobile system can detect that a user never uses his or her phone while at work, and hence all the calls or messages are directed to the user's voicemail when they are working.
