This tutorial, presented by lynda.com, focuses on Fitts’s Law, which states that it is “faster to hit larger targets closer to you than smaller targets further from you”.
The video begins with examples to clarify the understanding of the law. For example, the brake pedal in cars are larger than the accelerator pedal, making it easier to press in emergencies, and the off button on heavy machinery is larger than the on button. These examples reinforce the meaning of Fitts’s Law.
The video then moves on to speaking about how this law fits in to computer interfaces and websites. The video touches on positioning of links (whether it is in the centre of the page or on the side), and whether to use one word or a phrase for hyperlinks. Furthermore, it speaks about touch interfaces and the spacing involved. These tips provided in the video work towards helping developers improve user experience for its users.
