Every key location has sensors that provide information to the users who can control it depending on the situation. This type of location identification, environment need identification and properties technology allow quality of context attributes that would match the user needs precisely (Huebscher and McCann 2004).
However, not all environments reflect such precision due to the variability of user location and situation. For example locations outside the home cannot utilize similar technologies of short-range sensors to allow context providers access to information directory. Instead, they have to rely on service directory and service configuration providers for adapting to the environment. Such middleware service providers tend to have limit access to context information. In addition, the potential of the devices using such information are limited also. For this reason research has been carried out to introduce trigger adaptation technologies in which context service providers are automatically connected with information hub based on an adaptation engine, which is triggered by events in the user's environment (Huebscher and McCann 2004).
3. Success/Failure Factors
Despite extensive research in the field of context-aware mobile media applications there is still a gap between context information technology and information available to human. The gap is a paradox, which diminishes the potential of context-aware applications. Information such as person location, proximity to others, preferences, sensitivity to physiology as well as environment all create a gap which limit the scope of context-aware applications development and delivery. A host of players including middleware providers, sensor information providers, mobile companies, application providers and users themselves are limited by the computing applications available commercially. According to Barkhuus (2004) "The context gap is the ever-present difference between human perceived use context and the possibilities for technology to represent and read a contextual state through sensor measures and directly manipulated electronic data." (Barkhuus 2004). Until that time, context-aware mobile media applications development would remain limited.
Some of the factors that hinder context-aware mobile applications include social-technical, prototype systems deficiency, device capabilities, context-aware information systems, and under development of human-computer interaction infrastructure. Nevertheless context-aware mobile media applications exploration has been ongoing since Weiser (1991) and researchers are of the view that computer-supported cooperated work would ensure the technologies will be developed to support future interaction capabilities.
