The interface may be good at completing the taks but if the user cant use the interface then they will not use it. You need to consider what type of user (novice or expert) is using the interface and how much help they need. The interface must be new and intuitive but people have to be able to predict how it works. And the design layout used selection time
Different people will have levels of Using UI. Therefore when choosing the features of the interface think about which features are accessible and which are new. As some people may think the UI is accessible if there is help.
Choose what tasks needs doing and whether your interface can complete these tasks. You need to consider what is necessary for the user to do a simple task.
Some users may have accessibility needs like sight or hearing. Developing a UI that covers everyone of the needs is impossible. But it needs to meet most needs to customize to meet them
Complete tasks on the interface quickly. As you don't want to wait ages to do a talk

little or no experience on interfaces and may be able to do a task, supervised by a user with greater skill, may not know how to go about a task to do it.
If someone is deaf then some text (alt text) or subtitles may need to be provided to make sure the interface is accessible to everyone. Visual needs alt text is also needed.
