ENVIRONMENTAL CONTEXTS SOFTWARE

Ĭontext-triggered actions: The software or applications can automatically invoke certain actions based on if-then condition-action rules.

Ĭontextual information and commands: By using context information such as location or user preferences, the software can present the user with commands that are filtered or personalized with context (e.g., send file command will send it to the nearby connected device by default), or it can change present user with certain execution options based on current location such as offer to silent the mobile device while in library.

The context information can thus be used to support personalized system configurations.

For example, device drivers can be loaded based on user profile. Īutomatic contextual reconfiguration: The process of adding or removing software components, or changing the interaction between these components is referred to as automatic contextual reconfiguration.It can also offer to connect to or share information with other users within the preset proximity and it can also provide information about nearby attractions and locations that the user might be interested to visit/explore, such as restaurants, gas stations, sports stadium, and so on. Such user interface can use user’s current location as default and can offer the user to connect or user nearby input–output devices such as printers, audio speakers, display screens, and so on. Proximate selection: Proximate selections refer to the user interface that highlights the objects or information which are in proximity of the user at a particular instance of query. Following are some examples of applications that uses context information. It can be used to personalize user interface, add or remove drivers, applications, and software modules, present context-based information to user queries, and perform context-driven actions.

ENVIRONMENTAL CONTEXTS UPDATE

For example, when the user is in a different time zone or location and “auto-update” is turned off in the user settings for these features, then the smartphone will not automatically update time and location but instead will prompt the user with all required information and let the user decide on subsequent action.Ĭontext information can be used in software applications to enhance user experience and facilitate effective hardware and software resource usage. Active context is also considered proactive context.Ī passive context awareness refers to processing where an updated context (based on sensor data) is presented to the user and user then has to decide if, how, and when the application should change. An example would be how time and location change in smartphones based on where the user is (provided the “auto-update” is selected for these features in user settings). Passive Versus Active ContextĪn active context awareness refers to processing that changes its content on its own based on the measured sensor data. Time context-time of a day, week, month, and season of the year. User context-user’s profile, biometric information, location, people nearby, current social situation. Physical context-lighting, noise levels, traffic conditions, and temperature.
