I am distilling problems and insights from the breakup letters, storytelling, and participatory design ideas by creating an affinity map. My wall is getting covered in post-it notes from all the notes I taking and once I am done I will start grouping items to get overarching ideas and new knowledge. These insights will inspire lots of ideas for my app, some of which I know will be thrown out.
I will decide on 3–5 ideas to explore and roughly sketch them. I will then refine these sketches and do paper prototyping. The user journey maps provide me with scenarios and tasks that i will use during prototyping. This kind of prototyping will quickly let me see which idea is best. After I have gained insights from that I will design various features for my app (e.g. a winking text bubble to convey flirting). I will build a testing blog to crowd source in order to see if my features affect emotion in the proper way.
