The Interactive Museum Team Presents: Interactive Museum Design Description and Project Status

Introduction General requirements –Mote network –Main Application –PDA Application –Web Application –Database Project Status What we will talk about?

Introduction General requirements Divided in 5 parts Main application - basic functionality Mote network - communication between motes PDA Application - gives visitor multimedia content Web Application - view exhibition from home Database - store information

Main aplication Has five main functions –Staff management –Visitor registration –Floor plan and mote administration –Exhibit content administration –Mote management Technologies –.NET framework 2.0 –C#

Staff management This part allow us to register new users –Two different types of users Administrator –Able to see all main application options (possibilities) Staff –Can only register new visitors and see visitors positions in a museum Also allow us to change user details –Name, password.... Or delete existing user

Floor plan and mote administration Allow us to present mote deployment in museum space (using preloaded map of the museum) Drag and drop functionality will make adding removing and relocating the motes easy Displayes signal coverage We will see visitors current positions in a museum and will be able to see attendance for each exhibit

Exhibit content administration Part for adding deleting and modifying exhibit related content –Allow administrator to chose video and/or static content that will be sent to visitors PDA –Creates links in database that will be used in data streaming module

Visitor registration When visitors come in the museum this is where we will register them –Using some personal data ( ) but never storing it, and links it with PDA IP address and mote ID –taking care of visitors privacy –Allows merging of data for previously visited exhibitions Administrator can delete information on visitors

Vision of the main application

Mote management Allows administrator to power up and shut down motes in the museum –Power up in the morning when museum opens –Shut down at the end of work time –Power up/shut down on will

Mote Control

Mote network requirements Detect visitors at every exhibit Identify visitor Identify exhibit Inform the rest of system about this Allow system to control network (start up / shut down)

Mote network - overview Three mote classes: Static motes –At every exhibit stand –Larger radio range Dynamic motes –With museum visitor –Smaller radio range Base mote –Connected to the server computer –Bridge between hardware and software part of the system

Mote network

Mote Communication Every static mote has unique ID Every dynamic mote has unique ID Dynamic mote Static mote Base mote Main application Main application

Communication - General Dynamic mote broadcasts it’s ID Static mote captures ID (if enough close) –Reports it back to the main application Main application can shut down / start up the mote network

Mote Technology Details Hardware mica2 motes –as static, dynamic and base motes Software TinyOS –system and component library platform nesC –writing mote programs

PDA Application

Development Windows Mobile 5.0 (OS).NET Framework 2.0 Visual Studio 2005 Windows Mobile 5 Emulator Communication Protocol TCP/IP over g

PDA Application Requirements Visitor can choose to recieve multimedia (text, images and maybe video) Add/remove bookmarks View history

Web Application Technologies 2.0.NET Framework (ASP.NET) IIS 6.0 Language C# Support for IE Explorer and Firefox

Web Application Requirements Visitor can: Login with ID View information from a particular exhibit List all visited, non visited and all exhibits List visits View bookmarks Send postcards to friends

Database Centralized data storage for all systems of the Interactive Museum MySQL 5 Exposed interface will be Web Services Security in mind Smart Caching

Database Main database content Information on Exhibitions Visitor statistics Mote information Information on PDAs Logs Employee information
