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. In % of all occurrences, the task is started with a scroll. This should be prevented as scrolling decreases the efficiency of the user and indicates, that not all required information is visible at once in the respective view. However, scrolling for reading of texts is no problem.
