    Task Assignment
    ?? ??

  • Week 2 (June 3 to June 9):

    👍 Decide language use to build this web application Abdallah suggested: PHP, JavaScript, HTML Everyone
    How should we make a map? Options: use a vector image (like google maps) or find use an existing map API Everyone
    • To do next week:
    Task Assignment
    Check if Abdallah received Beacons Everyone, Jennifer
    Be familiar w Javascript + React Everyone
    Read on EvoThings Everyone
    System Design Level 2 Kathryn

    Meeting notes: Start from scratch, Project should use a small area of some building to test

    Meeting notes 2: Not enough resources on web-application with bluetooth - starting with mobile application (made w js) then transition to web app. Use JS so easy to transition to web app later on. Everyone will be back in July so we all can work with the Beacons, physically. Use Evothings Studio, an IoT IDE, compatible with Estimote beacons

  • Week 3 & 4 (June 10 to June 22):

    Completed Task Details Assignment
    👍 Read the report To get ideas on what challenges we might face Everyone
    Learn JS (if not familiar) Build a simple app (with Evothings/PhoneGap) that takes data from estimote beacons. Extra goal: Build app that sends dummy data to test server, decide libraries later Everyone
    👍 Try out Evothings As above Everyone
    Build simple server Using Java or PHP Everyone
    👍 System Design Level 2 can be done anytime Kathryn

    As Above All

  • Week 5 (June 23 to July 3 (Wednesday) ):

    Completed Task Details Assignment
    Build test map The test map will be an array of dummy Nodes as JSON objects (eg. Shortest-path). These dummy nodes (JSON Objects) should contain: id, xy coordinates, type of room (Room/Hallway), events, adjacent nodes, and other data if any. Jennifer, Raghav
    Create Calculation Code Code used to create the graph / map Raghav
    👍 Work on UI Design Prototype Create a skeleton system UI, prototype screen-shots of system Kathryn, Yohen, Tommy
    • To do next week:
    Task Assignment
    Find out how to make array data display on a map Evothings Jennifer, Raghav
    Create Calculation Code Raghav
    Use data to construct graph Raghav, Jennifer
    Create skeleton of system design to working app Kathryn, Yohen, Tommy
    Take photo of school floor plan Kathryn

  • Week 6 (July 4 to July 10):

    Completed Task Details Assignment
    👍 School floor plan photo Photo of emergency exits? Fipke Floor 1 Kathryn
    👍 Test beacons that just arrived Test the beacons Kathryn
    Start building front-end Based on the prototype, build the interface (without map) on Evothings Kathryn
    Create calculation code Code used to create the graph/map Raghav, Jennifer
    👍 Figure out how to display map First, we need to know what to use to implement the map. (Once we get the beacons data, find a way to get them displayed.) Kathryn, Yohen
    Display JSON objects Put JSON objects on a table Tommy
    • To do next week:
    Task Assignment
    Find out how to make array data display on a map Evothings Jennifer, Raghav
    Create Calculation Code Raghav
    Overlay Minor regions on map Yohen
    Use data to construct graph Raghav, Jennifer
    Table of Minor # Tommy

  • Week 7 (July 11 to July 18):

    Completed Task Details Assignment
    👍 School floor plan photo Photo of emergency exits? Fipke Floor 1 Kathryn
    👍 Test beacons that just arrived Test the beacons Kathryn
    Start building front-end Based on the prototype, build the interface (without map) on Evothings Kathryn
    Create calculation code Code used to create the graph/map Raghav, Jennifer
    Plot user location Use the 4 Beacons to find the user's approximate location - using coordinates Raghav, Jennifer
    Plot user location Visualization of user location on canvas map Kathryn, Yohen
    JSON file read to HTML Put JSON objects from a JSON file on a table on a HTML file Tommy
    • To do next week:
    Task Assignment

  • Week 8 (July 19 to July 25):

    Completed Task Details Assignment
    Research Wifi Indoor Positioning Research more about using Wifi Access Points to get indoor position. Related keywords: RSsI, fingerprinting, trilateration Kathryn
    👍 Research Bluetooth 5.1 Research more about using Bluetooth 5.1 to get indoor position. Make sure it's Bluetooth 5.1 and not Bluetooth! Tommy, Raghav
    👍 Research More about google Indoor Mapping Google maps also allows Indoor location (for mapping), but can we make it accurate? Tommy
    Research on sensor fusion Find more info on using all available technologies to get indoor location Kathryn, Jennifer, Yohen
    Research on choke-point concepts Related to NFC, RFID Yohen
    Task Assignment

  • Week 9 (July 26 to August 31):

    Completed Task Details Assignment
    👍 Outside w Beacons See if RSSIs + interference have any changes when done outside. Results: No changes recorded. Interference is same as when tested indoors Kathryn, Raghav, Tommy
    Wifi Access Points Measurement w/out BLE Measure distances between Wifi APs Raghav, Jennifer
    Map Wifi Hotspots + MAC Addresses This can be done with the map which is done Yohen, Kathryn
    Research Libraries There has to be existing libraries or code online, we just need to glue it together Jennifer, Tommy
    Test Wifi APs with Beacons Can the Wifi APs RSSIs be more accurate with Beacons RSSIs? Tommy, Yohen

    • Map is done for FIPKE Floor 1 - use that as the thing

    • show results at next meeting

    • To do next week:

    Task Assignment

Long Term Goals:

  • Make a map of school
  • Set up indoor bluetooth beacons
  • Microwave locations Washroom / Assets etc.
  • Reverse Search (using events to find location) *
  • Check if room is booked / Schedule (Study rooms) and booking of room *
  • Classroom changes can alert client
  • Room information (# of chairs, etc.)
  • Immediate Temperature changes can alert all clients
  • Potential Business Idea???
  • Accessability for those w disabilities

Challenges:

  • Might occur from previous attempt:
    • iBeacon distance accuracy
  • Walls, Ceilings/Floors may hinder scanning of beacons

System Design Lvl 2:

System Design

Finding the Path to Navigate

When scanned, the Proximity Beacon will send the following data to the device (that is being asked for):

  1. UUID - fixed by manu.
  2. Major (In our case, the floor of a building)
  3. Minor (In our case, the area of a floor in that building)
  4. Proximity - how close the beacon is to the device
  5. RSSI - signal strength.

To find the user's estimated position,

  1. Scan for the nearest Beacons.
  2. Using the estimated proximity / RSSI, we can detect which Minor region the user is positioned.

To calculate steps, 0. Target will have a Minor integer assigned to it.

  1. Use shortest path from Minor integer of target, until Minor integer of start location / user.
