Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Design and Implementation of Mobile Electronic Memos: a tool to capture and share information in mobile environments Nicola Blefari Melazzi University of Rome, Tor Vergata, Italy Project site:

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Project Data and Starting Points EU co-funded project (a 30 months, 4.4 M€, project) – Mobile services have not matched the growth of the Web –Cost (of data access) –Complexity (in use and deployment) Vicious cycle: –high cost & few services -> few users –few users -> no incentive to offer services However, –Cost of broadband data access is decreasing (e.g. flat rate 20€ x month, max 500 MB; or 30€x month, max 1.5 GB; or 9€ per month for selected applications)

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Technical Motivation Success of the Web (among other factors) –Easy to use –Easy to create Mobile services –Unknown to users –Difficult to use –Not trusted –Difficult to design and deploy (especially for “small” service providers, e.g. SMEs, local government departments, NGOs, individuals)

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Design goals for SMS Mobile services have to be: –Simple to find –Simple to use –Simple to trust –Simple to develop

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Main achievements Idea of MEMs –notes with info about a location, a person, a service, or a Web site The MOVE client –an open source client software allowing SMS users to access services without passing through a conventional web browser Tools for developers (e.g. Authoring Wizard) SMILE –middleware for communication providing support for large distributed applications involving multiple heterogeneous devices SIM-based Security and Privacy –Exploitation of the security provided by the SIM card Design, production, and delivery of real SIMs Real life trials

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MEM: the problem… Imagine a tourist travelling through Seoul ( 서울특별시 ) Sometimes he needs information – for instance on how to reach a particular destination. Sometimes he needs to perform an action – like buying a theatre ticket It’s a very different scenario w.r.t. “googling” from a fixed PC Eight seconds rule…

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MEM: the problem… Well-designed mobile services may serve these needs but… If he sees the time of a show on a poster, all he can do is try and remember it, or write it down on a piece of paper, or perhaps on its mobile device If he wants to tell a friend to come and meet him at a certain café he has to ask the owner for the address (or read the address in Korean) and try to explain by phone to his friend how to get there

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MEM: the problem… Missing pieces: –Capturing information from the environment. It should be easy for users to capture and reuse information from the environment and from other services using mobile devices –Likewise, sharing (complex) information from the mobile device with other users and servers should be simple as well

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MEM: the idea MEMs are electronic notes containing a set of attributes associated with a specific class of information (e.g. information describing a location, a person, a service, or a Web site) Users can capture MEMs from the environment or from other services, store them for future use, share them with other users and send them as input to other services and applications MEMs can be created both on the mobile terminal and on a server –We developed a web application which lets the user create and display the MEMs and send them to mobile phones, but MEMs can also be automatically created (e.g. Restaurant MEMs from existing databases of restaurant information)

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MEM: the idea A MEM is used to handle information about places (like shops, restaurants, buildings, monuments), people, services, events Examples Guide patients to blood test room of a given hospital (MEM created by patient’s family doctor) Guide students parents to the University’s aula magna for the graduation ceremony (MEM created by students or by the University administration) Guide perspective buyers/clients to a shop/restaurant/hotel (MEM created by shop/restaurant/hotel managers, available on a web page and/or again sent via SMS) Guide a friend to a meeting place, to one’s country house, to … Guide a group of people to a common event (five-a-side match?)

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Usage scenarios for MEMs Leaving for Seoul –Mobile booking of a flight (send a digitally signed MEM, receive a MEM with flight info) –Few days later, at the airport. Using the MEM data, the airport provides the user with a “Take me to check in” service –Before leaving the user sends a MEM to a friend who will be picking him up on arrival. The friend will use the MEM to check for any delay in the flight. MEM

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Sending and sharing MEMs A key feature of MEMs is that they are easy to share and send to other users Where users have installed the MOVE client application they can send MEMs to their friends (e.g. a MEM with the time and place for an upcoming meeting) Alternatively they can embed the URL for the MEM in an , IM or message MEMs intended for use within a specific community or for users at large can be published to “MEM servers” which make them available to end-users in the relevant context

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. MOVE (Mobile Open and Very Easy) –MOVE is a sort of browser for mobile services; it is an open source, stand-alone J2ME (CLDC) application. It runs on a large set of terminals (both Symbian and Windows Mobile) –MOVE provides the capability to search for services and present the most suitable services according to users’ preferences and current context

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Business scenarios Vertical applications Single SMS provider / “walled garden” approach Open / multi-provider approach

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Vertical application Examples: –a gaming application offered by a web portal –a social networking application (e.g. soundtribes) –an application to find people/places at a conference center –an application to manage agendas of travelling workforce –a tour guide application A different stand-alone application on the phone for each example (installing an application is very easy, for example by sending a Bluetooth message!) Server side facilities are not linked Each server side will handle its own “subscribers”

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Single SMS provider / “walled garden” approach Examples: –a set of services offered by one organization The client is an application on the phone customized by an SMS framework service provider Services are offered through the mediation of the SMS framework service providers

Session 12b, 12 June 2009 ICT-MobileSummit 2009 Copyright 2009 Project S.M.S. Open / multi-provider approach There is a single application on the phone (the MOVE client) that can connect to different SMS framework service providers and to any service Services can be offered through the mediation of the SMS framework service providers Services can be offered without any mediation Users can be linked to a “default” or “home” provider that can offer services (e.g. assists the user in search/customization)
