Sense Intro

  1. 1. Sensors are everywhere Steven Mulder [email_address]
  2. 2. Mission statement <ul><li>Modern smartphones </li><ul><li>Many sensors
  3. 3. Many networking options
  4. 4. Easily available </li></ul></ul><ul><li>Other sensors/actuators </li><ul><li>Even more sensing options
  5. 5. Customized for specific purposes </li></ul></ul><ul><li>Networked intelligence </li><ul><li>Smart combining of sensor data
  6. 6. Smart sharing of useful information
  7. 7. Don't depend on having 1 perfect sensor </li></ul></ul>Sense aims to improve human communication and coordination by achieving situational awareness through:
  8. 8. Smartphone and sensor node Microphone Camera Accelerometer Light sensor Touch sensor Battery level Bluetooth Wi-Fi GPRS UMTS GSM GPS Speaker Vibration Display USB Calendar data Communication records Human sources Orientation Proximity Internet sources Accelerometer Temperature Light Infrared (movement) Bluetooth * MyriaNed Serial port Orientation CO 2 Indoor location Sensors Actuators Connectivity Virtual Sensors
  9. 9. Three Steps in Situational Awareness <ul><li>Status observation and prediction </li></ul><ul><ul><li>Reachability of the user
  10. 10. Location of the user
  11. 11. Activities (in general) of the user
  12. 12. Properties of the environment </li></ul></ul><ul><li>Networked intelligence </li></ul><ul><ul><li>Share sensor data with other devices
  13. 13. Combine multi-modal sensor signals for richer data </li></ul></ul><ul><li>Smart interaction </li></ul><ul><ul><li>Don't just observe what is happening!
  14. 14. Share information with other people when this is useful
  15. 15. Support and coordinate human communication and transactions </li></ul></ul>
  16. 16. Sense software suite <ul><li>Local network </li><ul><li>Mesh network with gossip protocol
  17. 17. Linked to external world via smartphones
  18. 18. Does sensing and actuation
  19. 19. Preprocesses sensed data
  20. 20. Interacts with other platforms (e.g. ASK or Regas) </li></ul></ul><ul><li>Remote host, “CommonSense” </li><ul><li>Cloud intelligence
  21. 21. Remembers, combines, analyzes sensor data
  22. 22. Also interacts with other platforms (e.g. ASK) </li></ul></ul>Sense delivers a development platform consisting of two parts: Local applications CommonSense Other platforms
  23. 23. Advantages <ul><li>Do more things with more intelligence </li><ul><li>no more manual logging: automatically register what is happening
  24. 24. immediately notice abnormal behavior
  25. 25. minimize coordination problems between links
  26. 26. real-time information means better planning possibilities </li></ul><li>Ease of use of wireless sensor networks </li><ul><li>virtually no infrastructure costs
  27. 27. up and running within hours
  28. 28. reliable against breakdowns of individual devices </li></ul><li>Open architecture </li><ul><li>no proprietary black boxes
  29. 29. works with pre-existing infrastructure
  30. 30. flexibility for scaling/updating </li></ul></ul>
  31. 31. Current situation <ul>Working on pilot projects: <ul><li>Building management system
  32. 32. Location-based time registration (Regas)
  33. 33. Sharing reachability status via webservice (ASK)
  34. 34. Indoor localization </li></ul>Looking for more! </ul>
  35. 35. Example 1: Reachability <ul><li>Key issue in emergency response
  36. 36. Observe and predict if / when a user can be reached.
  37. 37. Automatically pick the right communication channels. </li></ul>Already in a call, arrange callback? Too noisy to talk, send SMS? Not near phone, call a friend?
  38. 38. Example 2: Location <ul><li>Observe and predict where the user is.
  39. 39. Multiple sensors: </li><ul><li>GPS
  40. 40. Calendar
  41. 41. MyriaNed sensor nodes
  42. 42. GSM cell towers
  43. 43. Known Wi-Fi access points
  44. 44. Other users </li></ul></ul>Bringing the kids to school, back in 20 minutes. In traffic, will be 30 minutes late for the meeting. Having a walk in the park, everything is fine.
  45. 45. Example 3: Activities <ul><li>Recognize activities of the user and learn which ones are relevant.
  46. 46. Check with user or other devices for feedback. </li></ul>Having a 10 minute rest stop Attending G20 summit with Barack and Angela Measuring a patient's blood pressure
  47. 47. Example 4: Networked intelligence <ul><li>Use the network of sensors that exists around us
  48. 48. Share sensor data with neighboring devices
  49. 49. Combine multi-modal sensor signals </li></ul>Does anyone know where we are? No problem! I have GPS. I think I heard something fall. I just hit some- thing hard! I could call the neighbours... Something just moved. I heard breaking glass! The light was switched on. Something is moving.
  50. 50. Example 5: Smart interaction <ul><li>Act upon the knowledge about the user and his environment
  51. 51. Help the user in smart ways </li></ul>Hello, I am here for a meeting with Mr. Lee That's my guy! I'll send you his business card. You just bought toma- toes, pasta, chips... OK, I will scratch those off the grocery list and notify Mrs. Carrot. Careful! You are moving away from the nearest CPR-person.
