Coursework 2 - overview G54IHC
Introduction to Human-Computer Interaction Coursework 2 – ‘Evaluate your interface’
Dr. Gail Hopkins

• Evaluate your interface • Worth 50% of your overall mark for this course • Consists of:
– Group report – 60% of your coursework mark – Individual report – 40% of your coursework mark

• Working in same groups as previously • Using the interface you have developed for CW1
– So I hope it’s ready!

Coursework 2 – Group Activity
• You must evaluate your prototype in 2 ways
1. 2. Using a method that utilises actual users, the ‘cooperative evaluation’ process discussed in today’s online lecture Using a ‘cognitive walkthrough’ (each member of the group should do this individually)

Coursework 2 – Group Activity
• You can do the cognitive walk-through evaluation in your own time – or using the lecture time we are not using at the end of term • You can also do the cooperative evaluation with live users in your own time – but you will have to find your own participants – it’s probably easier to get it done in next week’s lecture.

• Next week we have 2 lecture slots available.
– You must attend both sessions – Monday 9am Groups 1-12 will evaluate their interfaces (others act as participants) – Monday 12noon Groups 13-25 will evaluate their interfaces (others act as participants)

Coursework 2 – Cooperative Evaluation days
• Use the participants made available to you • I would suggesting running at least 3 participants through your interface • Remember the process of research • Remember the code of conduct • Think about what task(s) you want people to perform with your interface • Think about how you will record their activity / responses

Coursework 2 – Group Report
• The report will:
Introduce and describe the interface (very briefly) Set out the aims of the research Describe the methodology Detail the results of the two types of evaluation separately Summarise key recommendations for improving the design Discuss the findings

• In the discussion section the report should explicitly compare the relative strengths and weaknesses of the two different evaluation approaches and critically examine their relative contribution and the different types of insight they generate • The maximum word limit for the group report is 4000 words • I will provide a template for you for the report

Coursework 2 – Individual Activity
• Perform a heuristic analysis on your group prototype
– You should decide on the set of heuristics that you are going to use
• We have covered different sets of heuristics from different design experts in the lectures, and there are others

Marking criteria
• Group report:
– Have you set out the aims of your research? – Have you described your methodologies? – Have you clearly presented the results of the two evaluations? – Have you discussed your findings in light of research literature in the field? – Have you given key recommendations for improving the design?

– You should write a report discussing the results of your heuristic analysis, including:
• Why you chose that particular set of heuristics • How you applied each heuristic to the group prototype • A considered discussion of how the prototype does and does not conform to the heuristics (and any conscious decisions that were made as part of the design process regarding this nonconformance)

• Individual report:
– Have you justified your choice of heuristics? – Have you explained how these heuristics have been applied? – Have you detailed your findings from this application of the heuristics?

– The maximum word limit for the individual report is 1500 words

Coursework 2 – important details
• Deadline for submission of both reports is: – Friday 14th December, 4pm • Each group should submit one report for the group coursework • Each individual should submit a separate report for their individual coursework • Submission should be to the school office
