When labels are not sufficient, use text tiles to identify the purpose of individual tiles or dialog box areas. You can also use text tiles to display status messages or reminders, including error messages and warnings.
Text should be direct and unambiguous. Describe options and entry fields in terms your users would use. For example, the error message “Invalid entry†in a list box conveys little information. A message such as “Layer does not exist†is more helpful.
Align messages with the control tiles they describe.
Put text that identifies a group of control tiles or a section of the dialog box above the tiles that the text describes.
