Regionales Undo/Redo für Multi-User-Anwendungen auf großen interaktiven Oberflächen

Although the use of undo and redo in desktop applications has been largely resolved, the behavior within different combinations of group and individual use on large interactive surfaces is still uncertain. For this purpose a study was performed that evaluates the expectations of the users within multi-user scenarios. The study pointed out that users mostly expect a regional undo. Therefore different techniques of regional undo within a multi-user scenario are presented. Furthermore a generic undo-framework was developed that provides the technical basis to implement regional undo in a multi-user application.
