    • Matteo Picozzi http://home.deib.polimi.it/picozzi {picozzi@elet.polimi.it} Doctoral Consortium CHI Italy 2013 Trento (TN) September 16th, 2013
    • UI Web Applications public APIs widgets data sources Mashups
    • Vertical Mashups are applications for particular needs
    • Contingent Mashup might be useful for a short period of time
    • Composable Reuse of building blocks, called components
    • Flexible It’s easy to adapt mashups to new needs changing components or synchronizations among them
    • Lightweight Mashups are usually lightweight applications
    • Housingmaps • Mashups were born to meet real user needs • An example is Housingmaps.com, the first map mashup: - In 2005, Paul Rademacher overlays data from Craiglist on his Google Maps hack - Then Google decided to open up the Google Maps API for developers - And Google Maps become the preferred mapping platform for the web
    • The first mashup developers were hackers who however discovered a world where also end users can take advantage of mashup solutions for their needs
    • It is not easy to predict end user needs...
    • Numberofusers Number of web applications Developed applications Market opportunity for mashups
    • Web 2.0 Active co-creation of new ideas, knowledge and simple applications Culture of participation User involvement in the creation of contents Collaboration among users through web applications End User Development
    • With the right tools also end users can develop their mashups
    • Resource Selection Mashup Composition Usage and Maintainance Dismissal Mashup idea Manual development of mashups
    • Resource Selection Mashup Composition Usage and Maintainance Dismissal Mashup idea Component Editing Mashup Sharing and co- creation Manual development of mashups Tool-assisted and Registration Reusage New New
    • • Abstraction from technical details - A platform speaking the user language (functionality and terminology), possibly through visual mechanisms • Continuous feedback - Immediate visual feedback → immediate mashup execution • Composition support - Assisted composition, e.g., by means of recommendations • Domain specific focus - A platform restricted to a well-defined domain the user is comfortable with The need for composing an application, starting from resources responding to personal needs, and simply running it, without worrying about what happens behind the scenes, arises

    • • UI Template - Set of “empty” visual elements called visual renderers - Different kinds of VT - Must be filled by data List Map Chart
    • Image Title Subtitle UI template item Data Data representation Mapping <visual-mapping> <global type="List"> <vr name="Title" type="Text"> <data source="IMDB" query="/title"/> <data source="MyMovies" query="/@name"/> </vr> <vr name="Subtitle" type="Text"> <data source="IMDB" query="/director"/> <data source="MyMovies" query="/@director"/> </vr> <vr name="Image" type="Image"> <data source="IMDB" query="/poster/image"/> <data source="MyMovies" query="/@photo_url"/> </vr> </global> </visual-mapping> Schema Export for multiple devices

    • • 3 experiments - Mashup dashboard - Component editor - Collaboration mechanisms • Goals - Demonstrate that end users (whether skilled or not) can execute tasks and develop mashups - Compare the behavior of technology expert users and non-expert users • Setup of the experiments - Tutorial - Filling of the pre-experiment questionnaire - Observation of the users during the execution of increasing difficulty tasks - Filling of the post-experiment questionnaire • Analysis of - Efficacy - Performances (time of execution of tasks) - User satisfaction • Results - No significant difference between expert and non expert users
    • • Mashups are suitable for EUD • Coverage of the entire lifecycle • Lightweight development process • Platform for EUD - Component editing for multi-device mashups - Mashup dashboard - Collaboration • Validation of the approach through user studies with encouraging results
    • • Improvement of the real-time collaborative editing • Adoption of different kinds of service standards • Apply already studied recommendation techniques in order to help users select adequate resources • Increase the flexibility and usability of our environments • Improve mechanisms for domain specificity
