If I was to work further on this prototype I am now at the stage where I would get some input from possible users. Doing a few informal tests would most likely give me more information and some new perspectives to further develop my prototype. This would help me to get it to a stage where I can learn more from more “proper” testing.
After this development I would do a more extensive testing round to decide whether or not this is the right direction. I would anyways have new perspectives to bring to a different prototype, so my work would not be lost if I found that a different format would be necessary.
