MADE
We have developed a toolkit MADE: Mobile Application Development Environment designed ad-hoc to support the creative approach of
multimedia applications on mobile devices
MADE is composed of:a visual development tool through which developers (also not programming experts) can develop their own applications for mobile devicesA scripting language for the description of MADE appsA set of modules to support localization and proximityGPS, RFID
A set of player to run MADE apps on mobile devices until now Windows Mobile and PCs

MADE RFID
The MADE RFID module implements a proximity algorithm based on scanning of tags in the area
it support the iCARD Identec reader
Why RFID?Availability of long-range (up to 100 meters) long-range
communication with long-life (up tp 5 years) battery life– Bluetooth: no long-battery life
Why Windows Mobile?Simple to add hw modules with Compact
Flash interfaceWe plan also to port MADE on Android
and iOS

Main outcomes
Through MADE developers can combine the multimedia content, GUI controls and proximity awareness components
images, videos, buttons, maps, position, nearest objects etc.)
to easily build multimedia applicationsnot as flexible as the manual coding
easy to use
hides language-specific complex aspects
speed-up the most routinely parts of the work
rapid prototyping

Example of applications
Examples of applications developed with MADETour guides Genoa AquariumPalazzo del Principe Museum
Territorial gamingVeGame: a treasure-hunt game
which challenges players at the field discovery of the Venetian heritage
ScienceGame for “Festival della Scienza”
Visual impaired support: LodeStarEuroFlora 2006Villa Serra (a naturalistic park in Genoa) 2008Museo del Mare (a museum in Genoa) 2010

Visually impaired support
Using sensors (RFID), we provide visually impaired people with location-related added value information on objects and spaces
The guide supports usersby identifying important object-to-self and object-to-object spatial relations

«Villa Serra» (naturalistic park)
Spatial distribution on “Villa Serra” natural park. Red spot represent the RFID tags (66 tags)

«Museo del Mare» (Museum)
Spatial distribution on “Museo del Mare” museum (80 tags, picture shows only 2nd floor)

Design goals
not an assistive technology to allow visually impaired people independent navigation
a support to better appreciate in an independent way cultural and natural contents
an exhibition in a museum, a walk in a natural park
not a tool “only” for visually impaired people, but a tool for all
an event-driven operational mode
only alerts, information on demand
contents written for visually impaired people highlighting olfactory and tactile sensorial information
DEMO

DEMO (from «Museo del Mare»)
An initial two minute tutorial stage users could experiment the tool interface by pressing freely the controls
The event-driven UI provides information when users are in the proximity of tags.
a pop-up window and an audio alert
just-in-time: alerts are offered to the visitor in the exact moment of the requirement
If the user wishes listen to the description, he can press the touch screen
low intrusiveness: the user is asked about his willingness to accept the contents

Experimental results
Experiments with real users in a real context of use
LodeStar can contribute to improve visually impaired people’s ability
to learn a route through an unfamiliar area
recall important features in the environment, like tagged points-of-interest
As an example:A sketch of the natural park map draw by a subject
The user have correctly identifiedthe entrance (I), bar ( R), the lake center (X) and his initial path (V)

Conclusion
Support for Rapid prototype of mobile guide
proximity awareness
Different application typesTuorist guides
Territorial gaming
Visually impaired tools
A set of real-world applications deployed
User-test results gives good fedback from end-users
