In order for users to interact with online websites, they must trust the security and validity of that site. If we can measure users’ levels of trust during online interactions in usability studies, we can ensure that a given website is designed appropriately to maximize users’ trust. We can work on measuring task completion time and accuracy, factors such as mental workload, frustration, and distraction done by qualitatively observing users or by administering subjective surveys. To get a better understanding of what problems the user faces, you need to put yourself into the user’s shoes. From the user’s perspective, your product needs to address the needs the user has. User needs come in two types. Needs that the user can articulate are also known as perceived needs, the other one is the user’s experience current products may limit their ability to imagine a different type of solution named latent needs.
There is no doubt that one of the biggest problems can be unreliability responsible for the frustration of a user while using a website. When a user stumbles upon a broken link, an irrelevant CTA button, or a 404 error, they probably won’t be patient enough to stay and try again. Another reason which might rage the user’s patience would be speed, more than 40% will abandon your website if it takes more than 3 seconds to load, whereas the visitors become even more demanding when it comes to mobile experiences. That is why user-friendly modes are always a solution to your and your user’s problems.
The ability to acquire objective, real-time measures of a computer user’s mental workload while he/she works with a computer would be valuable to the field of human-computer interactions. Measures of users’ mental workload could be acquired during usability studies to help interface designers to pinpoint areas of the interface that may be un-intuitive for users.
