In this paper we describe the prototype of a location-based M-tourism application called My Italy, developed by the Usability and Accessibility Laboratory (LUA) University of Rome Sapienza. My Italy is a mobile multimedia tourist guide capable of supplying the mobile user with context-aware information during travel in a fast and easy way.

    • Main Characteristics of MyItaly
      The main characteristics of the system are:
      GPS localization
      Updated information through the wireless network
      Multimedia Presentation (SMIL)
      Guided Tours vs. Serendipity
      Modular Information Architecture

      Objective = Simplicity + Rich User Experience
    • Challenges: Displaying Info
      Provide fast and correct info
      Avoid cognitive overload
      Capture user’s attention
      ENTER 2010 RESEARCH TRACK
      8
      Map and Icons: images allow access to information at a glance. Map zooming is related to POIs density.
      Text Alternative: makes searching for information easier.
      Multimedia presentations: present some brief facts in a far more engaging way, showing perspective and details that are not normally visible by the user.
      Information Architecture: different levels of content helps to avoid cognitive overload.
    • Challenges: Navigation
      less time to plan -> need to plan on the go
      need to harvest time -> pre-planned tour
      freedom to choose -> serendipity
      ENTER 2010 RESEARCH TRACK

      Guided vs. Random discovery
      Nearby suggestions : the application will communicate the proximity of POIs, routes and potentially interesting events for tourists through a vibration of the device. In this way the application meets the typical discovery needs of a journey.
      Guided tours : pre-planned itineraries organized in categories. Set info is available at a glance: the distance from the starting point, the length and duration of the itinerary. Multimedia presentations are also available.
    • The Prototype
      TechnicalCharacteristics:
      • Developed using Java ME
      • GPS localization (built-in or via Bluetooth connection JSR 82 API)
      • J2ME polish for a flexible UI
      • Client/Server architecture
      • SMIL player

    • The UI: the Map
      The User Interface:
      ENTER 2010 RESEARCH TRACK
      11
      A tab menu shows at a glance the main sections
      and allows horizontal navigation
      (optimized for a 240 x 320 screen).
      Icons and labels for fast recognition of POIs.
      User’s position, at the centre of the screen,
      showing the closest surrounding POIs.
      Options menu: to filter, search, and have a textual alternative.
    • The UI: POI Details
      ENTER 2010 RESEARCH TRACK

      A briefdescriptionispresented on the first page. By scrolling, the user can access more detailed info.
      Text isreadableby the most common screenreaders.
      A multimedia presentationisavailablefor the mostimportantPOIs.
    • The UI: Guided Tours
      ENTER 2010 RESEARCH TRACK
      13
      Step 1:
      A list of the closest “Guided Tours” available is shown.
      The “others itineraries” button extends the seeking range.
      Step 2:
      An overview of the tour and a few options:
      • starting the tour,
      • seeing an audiovisual presentation ,
      • displaying the route to follow.
      Step 3:
      A brief textual description and a few options:
      • extended description,
      • see an audiovisual presentation,
      • next stop.
    • The UI: Events
      ENTER 2010 RESEARCH TRACK

    • Results & MainIssues
      All users completed the tasks.
      80% of users find MyItaly easy and fun to use .
      Weaknesses:
      Map: problems getting oriented, latency during rapid movements ,and fast user interaction (i.e. Scrolling) .
      Absence of social – personalized functions.
      Strengths:
      Multimedia presentations: even if interrupted, users tend to remember multimedia presentations better than textual ones.
      Modular Information Architecture: ease of finding information.
