The ratio of interactions that enter text into text fields is relatively high in comparison with the other user interactions ( %). This should be reduced. As an example, entering data can also be done using check boxes or combo boxes in the case predefined values must be entered. In % of entering text into text field , the same text was also entered into text field during the same session. Perhaps this can be automated, so that the user does not have to reenter the same text several times into different text fields. % of the text entered into text field was no letter or digit. This is an indicator that the entered data has to follow a specific syntax. This should be supported by syntax checking, auto completion or even providing the text fields in a way that does not require the entering of special signs as they are already included at the right positions. The task covers % of all recorded user actions. Therefore, it should be executed with a high efficiency. You should consider making the task more efficient, by minimizing the number of actions to be executed by users for fulfilling this task. For executing task , the user has to execute a high number of inefficient actions ( % in average). Such actions are, e.g., scrolls. The number of inefficient actions should be as minimal as possible to increase the users efficiency in executing a task. Please check the task structure for occurrences of the following event tasks and consider to prevent them: scrolling. In % of all occurrences, the task is succeeded by . This shows, that both tasks are likely used in combination. Please consider to support the execution of both tasks in one user action, e.g., by providing an appropriate button, to reduce the number of actions to be performed by the user. In % of all occurrences, the task is preceded by . This shows, that both tasks are likely used in combination. Please consider to support the execution of both tasks in one user action, e.g., by providing an appropriate button, to reduce the number of actions to be performed by the user. For executing the task , the user utilizes GUI elements on average. As these GUI elements have a high distance to each other ( on average ), they should be more colocated to ease the execution of the task for the user. A click on the button seems to be missing user feedback. In of uses, the button was clicked several times. The average waiting time between two subsequent clicks is seconds. This is typical user behavior if the user does not see progress following his actions. Please consider showing the user some progress after he performed the first click. This is especially important if the operation triggered with the click usually takes longer than one second. This defect was observed based on task . % of the GUI elements ( of ) are not used. This can have several reasons. Either they are not visible to the user or they are not required. If they are important, they may not be recognized by the user. This can be caused by visual design or because they are too hidden. If they are less important, they can either be removed from the GUI or relocated to a less prominent position. The unused GUI elements are:
