Assignment from the previous week Self-evaluation of your work from the previous week (storyboard / paper prototype) Start a journal on your personal page documenting the work you have personally done, and your personal thoughts & ideas – Back-fill with work you have already done – Include self-evaluation – For every activity done by your team, you should post documentation of your personal contribution and self-evaluation Not everyone has to do every task, but everyone has to do significant tasks in the team activity – This will, in part, determine your personal final grade I can’t grade you if I don’t know what you have done I will provide evaluation templates as appropriate

Put an implementation proposal and plan together – See the sample on wiki – You have 2 weeks to build the prototype so limit your scope accordingly starting May 18th + 1 week for testing – Identify platform – Decide what backend functions you will “fake” and how – Should be demo-able in class on June 9 th 2012 No coding till you finish heuristic evaluation step

Assignment for the coming week: 1 Bring yourself and your team up to date on the assignments so far You cannot do any coding till you are up to date and I give the OK me if you have any questions
