This lecture was extremely beneficial coming to the end of the music app project, for example, this prompted me to scale down my nav icons to make them more easily clickable on the phone screen, and also slightly move up the nav so that the user does not have to stretch to reach the points of interaction.
I also researched the Laws of UX this week. One which especially stood out to me and assisted in the final stage of creating the music app project was the law of uniform connectedness. I used this to show that the icons with a large circular frame are all navigated by scrolling, framed all nav icons in grey to show that they navigate between pages, and framed clickable items with a semi-transparent box.
