– Example Applications– Patterns for Ubiquitous Computing– Application Development Process

• Scenario Analysis• Assignment

Outline

UbiComp problems solved by MundoCore

• communication in loosely coupled systems• integration platform: call from Java to C and back• sensing real world information

– Location… (also available: weight, pressure, QR-codes)– RFID / Transponder

• Simulation and Testing– Dummy services (console in/out)– WorldView

What is MundoCore?

• communication middleware– Pub/Sub – RMC– Java bindings

• set of generic services– WorldModelStore– Location Systems

• development tools– WorldView

• hardware devices (… not shown)– Talking Assistant

• documentation– MundoWiki

What is MundoCore NOT?

• useful to end-users!!

MundoCore is a platform for building applications!!!

It is useful for the developer of a UbiComp application

Application Development

• define services– what is the interface?– where will it run?– use low level services as hardware abstraction layer

• e.g. sensor sensing service

• implement services– in MundoCore– dummy implementations of low level services

• console in/out, test dummy

• test system– high level services – protocol low-level high level

• deploy– compile low-level services with real hardware

Designing Your Own UbiComp App

10

• think of an everyday scenario– shopping, cooking, transport

• identify a concrete problem• propose a solution based on UbiComp technology

– save time– save money– more fun– better experience– …

• why would someone pay for this?– how much?– who?


©

Analyze your ideas

• SWOT: Does the idea have business value?– strength, weaknesses, opportunities, threads– don‘t restrict yourself too much (hardware costs, deployment

problems)

• Scope: Can we implement a significant part of the idea?– TK3 time frame: 6 weeks– complexity: Not much experience with MundoCore / UbiComp

• Sane: Can the same thing be implemented „lowtech“? • „Coolness“: Will we be able to show the key points of

our solution in a video?– „business“ scenario <-> everyday scenario

Assignment 3: Your Own UbiComp App

• It must involve– data from at least one sensor (location, weight… ) or RFID

reader– user interaction away from the desktop (speech, gesture,

GUI on mobile device)

• hand in– 1-2p Description of your application– situation as-is– concrete problem that is solved by ubicomp– how does your application make the world a better place?– technical aspects: which sensors? how does the user

interact?• this should be detailed enough to make us believe you are able

to implement it

• 4 slides in max. 8minutes in next weeks session!

Assignment 3: Your Own UbiComp App

• Grading will be done on the quality of your documentation / presentation

• Documentation 75%:– is the scenario comprehensive and understandable?– does it use pictures for illustration?

• e.g. UI mock-ups, scenario photos…

– are all necessary parts (sensors, interaction) identified?

• Presentation 25%:– time-limit kept?– message came across?
