This blog links in with Nathans in relation to the Forum Nokia Developer Day to be held in Budapest in November and relates to my talk which will be on Mobile Users Generated Content (UGC). The emergence of large scale UGC marks a shift among particularly for media organizations from creating on-line content to creating the facilities for non-media professionals (i.e., 'the rest of us') to publish our own content in prominent places. Mobile phones are particularly well suited for this type of media creation as they always carried and are therefore immediately available to the users when required. In my talk I will illustrate through example both the power of user generated content and how it may be harnessed but also the opportunities for utilizing the greater contextual awareness and flexibility the mobile phones offer over current online services. As a taste of what you might expect consider the following figure which relates to the density of user generated geo-located photographs from our LocoMash project for the Roskilde Festival in 2007 (left) and 2008 (right). We can not only see a greater density in 2008 (no doubt partly due to the better weather) but also the relative similarities over the two years indicating the primary areas of interest are consistent for the event which illustrates that UGC through mobile can provide and interesting insight into user behaviour at such events.
