I studied the MSc in HCI with Ergonomics at the UCL Interaction Centre, the course is split into four terms over a 12 month period (full time) with the first term covering the two ergonomics modules one of which is a two week project where you work in teams to solve a task such as design and build a mockup for a walk up and use kiosk for a book shop. This term will set the foundation for the following three terms (including the dissertation)
The second term contains modules that you can select based on your interests such as organisational informatics (understanding how a complex system is perceived and how social structures exist in large organisations such as the many stakeholders of an e-learning system in a university) or affective interaction (how peoples emotions play a role in the design and use of systems). This term ends with another two week team project like the previous terms ergonomics project but this time you are required to apply all of the skills gained from the previous two terms to design and test a concept such as a navigation device for ramblers aged between 50 and 65.
The third term is largely a solo effort where you will have several projects to complete.
Finally the fourth and last term is the three month long dissertation which you could do on a topic of your choice, students from my year studied topics such as how to accurately measure emotions during game play, ethnographic studies on the use of GPS devices.
One of the most valuable parts of this course is a weekly seminar with speakers from organisations in the UX and ergonomics fields. This gives you the opportunity to network with potential employers and also to speak with them off the record and ask questions that perhaps you may not normally have the chance to ask.
On LinkedIn I have a group for fellow UCLIC alumni ( http://www.linkedin.com/groups?gid=1086337&trk=hb_side_g ) so if you are a member of LinkedIn that may be a good place to stop by and ask some of the members directly.
