DESCRIPTION
CityFlocks is a mobile system enabling visitors and new residents in a city to tap into the knowledge and experiences of local residents, so as to gather information about their new environment. Its design specifically aims to lower existing barriers of access and facilitate social navigation in urban places. This paper presents a design case study of a mobile system prototype that offers an easy way for information seeking new residents or visitors to access tacit knowledge from local people about their new community. In various user tests we evaluate two general user interaction alternatives – direct and indirect social navigation – and analyse under what conditions which interaction method works better for people using a mobile device to socially navigate urban environments. The outcomes are relevant for the user interaction design of future mobile information systems that leverage off of a social navigation approach.

Focus Group Interviews:Imagine you're new in a city and you want to find a good restaurant. What do you do…?
AnswersI think I would ask the local people. I would probably go to a shop and ask the local business people.
ProblemsWe are fairly elderly and we don't go out and ask 20 year olds or 25 year olds. They might not quite understand what we're talking about. It might be to do
I would do the same what Brooke did, you can only learn from asking around. We do read a lot but you also have to talk to people... and use any source of information you can get, that's the way you learn... I would like to hear everybody's version
I usually ask the people where I am staying. That's what I usually do. Although, sometimes I might have a guidebook where I pick out something. So it's a mixture of both... it usually depends on what I think about the people.
I always ask people who are like me. Sometimes it's pretty hard to actually find local
with the age...
Our age group determines I think to some extend. On the other hand, if you have relatives and grand children, that's different. You react different to them.
Sometimes I find myself up for adventure, so I don't go and ask people straight away like would look something up on a website.
I really like walking, like walking around and marking stuff for myself. So I wouldy p p p y ypeople in strange places that are not people who have a set of things to sell you anyway. So you really don't know whether you can trust them because they're actually about to make a bargain. So I usually ask people who are like me, because I think, well, if they had a good experience with a restaurant last night, then I am lucky to have one as well.
We sort of help out each other, well, with any kind of problem, we advice people where to go Magret the other day told me where the bus stop is I didn't know where
I really like walking, like walking around and marking stuff for myself. So I would go like, oh there is a doctor here, okay, so I will know for the next time when I need it or this is a library, just kind of a very exploratory kind of mode.
Professional Information SourcesWebsites and even information centres. Booklets, restaurant guides.
Outside Australia, definitely Lonely Planet. where to go. Magret, the other day told me where the bus stop is. I didn t know where the bus to the hospital goes from, so Magret showed it to me.
To me it actually doesn't matter what the age is or how they dress like you know it's just about trying to get some knowledge. And I will actually ask a couple of people to find out what the best idea is to do in that way, you know. Everybody has different thoughts and different opinions about things, so I would ask several people in that way.
I’ll ask friends who live there. How is it, where I go. Friends first, then websites.
I go to Wikipedia (for destinations outside Australia) (People then discusses the Wikipedia and show their positive attitudes towards its credibility)
I would probably Google it, if there was a language barrier with the local people, I would just look it up in the internet.
Do you feel comfortable ringing people for a short advice even I wouldn’t normally go somewhere unknown to me unless I’ve read about it somewhere saying it’s good, or someone says to me that it’s really good and I should check it out.
I would definitely just ask my friends to start with if I wanted to know about something. Might depend a little bit on, sort of the type of information that I was looking for. Maybe 'Is there a good doctor to see at the health service' for example. 'Which doctor would you see?' ‐ that might be a different type of information to 'Where do I get the
though you haven't kept in touch for a long time?I woundn't do it. Depends who it is, but that's rude.
I am actually okay with doing that with male friends, but I wouldn't do it with female friends.
If this was a close friend, it would be alright. But not with people you don't normally keep in touch withy g yp g
