During our last class period we tested our final visual and written directions for the tasks we chose a few weeks prior. The testers, who were unfamiliar with our projects, gave us a more realistic and thorough look into the pro's and con's of our directions. From what I witnessed, the simpler tasks that had less nuanced steps were the most successful. I saw a lot of difficulty in the interpretation of tasks that weren't necessarily straight forward. For example, my project had users attempt to adjust the rear shifting on a bicycle, which in order to complete successfully requires a lot of subtle adjustments based on textile and visual feedback. While most of the steps were attempted in relatively the right way, the end goal wasn't reached in success. Similar to how someone might attempt to tune a guitar based on a visual aid.. but they don't know what an in tune note sounds like... they turned the right things, but didn't really help things.
