HTML5 and KineticJS Based Web-

Client for PA System

Contents •Challenges •Target • Frameworks

– KineticJS – 3D research

• Design • Responsiveness Test • Demo • Lessons learned • Future work

Challenges

• Scalability Definition – Screen Size

– Platform • Device size

• Operating System

• Browser

– User Experience • Same user feeling with the application

• Similar template for various devices

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

Frameworks

• KineticJS

• HTML5 Canvas

• CSS

• JQuery

• WebRTC

KineticJS

•HTML5 Canvas based 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

3D Research

•WebGL (Web-based Graphics Library)

–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

3D Research

•Three.js

– HTML5 3D Library

•Models

–3D models software

–Google 3D Warehouse •3d models library that contains real airport models

Design

1. User interface

2. Navigation to different floors/zones/main building

3. Notifications to the user

4. User scenarios

Design

1. User interface

– Three separate tabs for main actions

• Calls, Monitoring, BGM

– Bigger screen size for every action

– Different interaction/representation for each action

Design

Design

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

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

Responsiveness Test

• Less than 250ms is acceptable

Device PC Tablet

Time ~ 212 ms ~ 70ms

Demo

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

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
