PreserVenice. The website can then be updated with the new information, saving the project groups from having to revisit each piece every year. Another significant use for crowdsourcing is Venipedia. As a user-edited wiki about Venice, Venipedia is a crowdsourcing outlet by definition. A user-edited wiki allows anyone to create and edit pages after creating a user account. People who live and work in Venice are more knowledgeable about it than groups of project teams who are only there for two months, so it is critical that they add their knowledge to the site.
One downside to crowdsourcing, however,
is spam pages. If any user can add pages, it follows that users can add spam pages. This is a particular problem for Venipedia. With no real website moderation, there are a large number of spam pages that have cropped up on the site in recent years. However, beginning this year, students of the Venice Project Center are looking to control the amount of spam that has been added to the wiki, as well as prevent spam from being added in the future. In dealing with the catalog of public art where each piece has a unique location, an augmented reality application is the most effective means of crowdsourcing. Layar47 is an application for smartphones that uses “augmented reality.” By accessing the camera and GPS location of the user, Layar “can recognize real world objects and display digital (augmented reality) experiences on top of them. These types of overlays in the program are called layers.”48 Figure 18: The Layar Logo
A previous WPI project team developed a layer for use in
Venice that would allow the user to see nearby pieces of public art49. The layer would receive its information from PreserVenice and display markers on the phone screen that would represent the location of nearby pieces of public art. However, the layer is incomplete, and requires additional work in order to function. Through integration with PreserVenice and Venipedia, Layar could potentially provide users with an interactive and informative tour of Venice. The application would access PreserVenice and display preservation data for the piece. The application could also lead the user on a tour of nearby pieces of art. If desired, the user could also access Venipedia and see the historical data about the piece. 47
