In this lecture we went over the most integral parts of UI and UX design that ensue usability. I found this lecture very helpful, and will put what I have learned into practice to improve my music app screens.

Jakob’s Law

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.

An example of Jakob’s Law in action is how most social media apps today have the navigation at the bottom, as this is what users have come to expect.

Fitt’s Law

The time to acquire a target is a function of the distance to and size of the target.

This law explains that the larger a target/ button is, the quicker a user can identify and use it.

Hick’s Law

The time it takes to make a decision increases with the number and complexity of choices.

This means that the more choices there are on screen, the longer it will take users to make decisions. Simplicity is best, as it doesn’t overwhelm users and streamlines the UX.

Von Restorff effect

The Von Restorff effect, also known as The Isolation Effect, predicts that when multiple similar objects are present, the one that differs from the rest is most likely to be remembered.
