Human-computer interaction is a part of our everyday lives. A component of HCI is usability, often used as a measure of ease-of use. People have been studying usability for a long time and a standard scale, the System Usability Scale, has been created to measure the usability of systems. To increase ease of use in websites, designers have been following the Three-Click Rule. As technology evolves, user expectations can be expected to evolve as well. Therefore, a pilot study was created and conducted to evaluate measures for testing the relevancy of this rule.
