On March 21st 2011, Art is Open Source held a lesson on the theme:
"Cross Media design scenarios: smartphones and tablets"
The workshop engaged the problems, approaches, methodologies and processes that designers can use in imagining, designing and implementing cross media design products.
Some energies were used to describe really interesting scenarios that allow using cross media design to implement solutions that are useful not only for business, but also for society, the environment and the cultural ecosystem, promoting a more tolerant, multicultural, sustainable take on the world.
These are the slides that have been used in the workshop, complete with a full end-to-end example of the creation of a location based application for iPhone/iPad.
