Context aware

  1. 1. Context Aware ComputingContexts relevant to the delivery of alerts Context Scenarios Context Aware Alert Delivery Amal Jyothi College of Engineering February 6, 2013 1 / 13
  2. 2. Context Aware Computing Contexts relevant to the delivery of alerts Context ScenariosContents 1 Context Aware Computing 2 Contexts relevant to the delivery of alerts 3 Context Scenarios The seriousness of alerts The current location of the recipient The current activity of the recipient The time The constraint specifications 2 / 13
  3. 3. Context Aware Computing Contexts relevant to the delivery of alerts Context ScenariosContext Aware Computing Context-Aware Computing can be defined as “an applications ability to adapt to changing circumstances and respond according to the context of use”. Context is typically the location identity and state of people, groups and computational and physical objects. Context aware computing aims at enhancing user experience by scheduling tasks for the user based on the current context. 3 / 13
  4. 4. Context Aware Computing Contexts relevant to the delivery of alerts Context ScenariosContexts relevant to the delivery of alerts The smart alert delivery system maintains a four dimensional lattice space for each patient-recipient pair The four dimension of the grid are Alert level(0-4) Location of the recipient Activity of the recipient Time of the day 4 / 13
  5. 5. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsContext Scenarios The seriousness of alerts The current location of the recipient The current activity of the recipient The time The constraint specifications 5 / 13
  6. 6. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe seriousness of alerts The alerts generated can be categorized into five levels beginning, fair, moderate, critical, and very critical. The mapping of the alarm level to alert level is dynamic and is set up by the chief consultant. 6 / 13
  7. 7. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe current location of the recipient The location of the doctor is typically determined by the GPS system of the Smart Phone that he uses. In the ICU automation system, any keystroke by the doctor on any of the applications provided by the system will result in re-evaluation of location of the user, from internal heuristics. 7 / 13
  8. 8. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe current activity of the recipient The current activity of the doctor may be going for rounds, performing a surgery, sleeping etc. 8 / 13
  9. 9. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe time The time of the day is another parameter considered by the system for determining the mode of delivery of alert. 9 / 13
  10. 10. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe constraint specifications The constraint specifications provide a set of rules that indicates the delivery mode of an alert based on the recipient, his location, time and activity. 10 / 13
  11. 11. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe constraint specifications.. 11 / 13
  12. 12. The seriousness of alerts Context Aware Computing The current location of the recipient Contexts relevant to the delivery of alerts The current activity of the recipient Context Scenarios The time The constraint specificationsThe constraint specifications.. The above code segment determines which mode of alert to be issued to the recipient. 12 / 13
