What did we get?	
What could we learn?
Rapid	ethnographical field research and	semi-structured interviews
help to understand the circumstances and	enable the collecting of real	
experience and	know-how.
Barcelona	is not	overloaded with high	number of ICT	services.
The	majority do	not	use the application as they do	not	have a	car.
The	participants who have a	car or use the application are satisfied with
the application and	recognize its need.
