Internship

  1. 1. REPORT OF INTERNSHIPImplementation of communications for safety navigation Heesung Lee
  2. 2. Outline Server GPS, direction, etc...GPS, direction, etc... navigation navigation “I lost my way...”
  3. 3. Required Client to server and server to client. Two-way communication less delay. Real-time communication
  4. 4. System outline Laser pointer arduino elderly side iPad GPS, direction, etc... Server navigation(right, left, ....)Operator side browser I tried to implement this part.
  5. 5. Client iPad This system needsServer 1. two-way communication 2. real-time synchronizedbrowser How do I implement them?
  6. 6. WebSocket standardized by normally protocol WebSocket protocol Server Server Client ClientProblem of normally protocol Good part of WebSocket protocolWhen client request to server, then server will It can send information from server andperform a response for the first time. either of the client. And less delay.The server cannot send to client only themselves.
  7. 7. The way of applying WebSocket. iPad Socket.io-objc (WebSocket liberally for Objective-C) Server socket.io (WebSocket liberally for node.js) browser
  8. 8. Future work. Laser pointer arduino iPad This is not so difficult. Because at this stage, iPad already has information of navigation. And this is not two-way communication.
  9. 9. Schedule about my Internship Understanding for Internship theme. Research the way of implementation. Construction of the development environment. Implementation Server and browser program. Implementation Server and iPad program. Visit Finnish friends’ cottage.(Tipasoja)
  10. 10. It was great experience to me. Kiitos!!
