  1. HTML5 and KineticJS Based Web-Client for PA System • TEAM 3 - K. Plataniotis , M. Mnitsakanyan , M. Mehrafrouz , S. Yildirim

  2. Contents • Challenges • Target • Frameworks • KineticJS • 3D research • Design • Responsiveness Test • Demo • Lessons learned • Future work

  3. Challenges • Scalability Definition • Screen Size • Platform • Device size • Operating System • Browser • User Experience • Same user feeling with the application • Similar template for various devices

  4. Target • PC 24” (Windows 7) • Chrome , Firefox, Safari • Tablet ASUS 10” (Android) • Chrome, Firefox • Tablet IPAD 10” (iOS) • Safari, Chrome • Mobile 3”-4.5” (Android) • Mini Opera • Mobile iPhone 3.5” (iOS) • Safari

  5. Frameworks • KineticJS • HTML5 Canvas • CSS • JQuery • WebRTC

  6. KineticJS • HTML5 Canvasbased JavaScript library • Canvas interactivity for desktop and mobile applications • Object Oriented API • Multiple layers to improve rendering performance • Ready to use and custom shapes • Transition and animation support • Drag and drop

  7. 3D Research • WebGL (Web-basedGraphicsLibrary) • Lack of browser support • Slow performance • Scalability requirement is not fulfilled • No added value on the current project • Trades off between performance and user experience

  8. 3D Research • Three.js • HTML5 3D Library • Models • 3D models software • Google 3D Warehouse • 3d models library that contains real airport models

  9. Design • User interface • Navigation to different floors/zones/main building • Notifications to the user • User scenarios

  10. Design • User interface • Three separate tabs for main actions • Calls, Monitoring, BGM • Bigger screen size for every action • Different interaction/representation for each action

  11. Design

  12. Design

  13. Design 2. Navigation to different floors/zones/main building • User interaction on maps • Mouse or touch • Events • Click on buttons to zoom / navigate / select zone • Drag map • Zoom with multi-touch and mouse-wheel

  14. Design 3. Notifications • Color • Opacity • Animation • Text messages on html elements and Kinetic Stage (canvas) 4. User scenarios • Predefined calls • Live calls • Zone monitoring • BGM channel control

  15. Responsiveness Test • Less than 250ms isacceptable

  16. Demo

  17. Lessons learned • Hard to find generic solution for different combinations • KineticJS • Advantages • Visualization of huge numbers of shapes/objects • Interaction with any of the shapes • Easy to learn and implement • Disadvantages • HTML5 canvas is pixel based • Alternative technology (SVG based RaphaelJS library) • Browser based 3D rendering is promising(e.g: WebGL, MapsGL) • not widely supported

  18. Future work • Additional notifications for the user interaction (animation, sound, vibration) • Appearance can be improved (e.g.: buttons, radio buttons) • Using KineticJS library for full application • Customized setting for each user after login • Use of WebRTC maybe is not the best option for this project • Keyboard Interaction
