Full vs. Limited Context Hierarchical Menu Structures for Web Site Navigation with Frames |
|
5. CONCLUSIONS 5.1 Impact for practitioners The results of this experiment suggest that full context menu structures may be the ideal hierarchical menu type for web site navigation. This is particularly true in cases wherein the menu is designed with a maximum depth of three and breadth of eight. However, it should be noted that the results of this experiment showed that where accuracy of information retrieval is concerned, limited menu structures result in fewer errors than full context menu structures. Nevertheless, the full context menu scores higher on user preference ratings than the limited context menus. User preference usually has a higher precedence over the accuracy of information retrieval and this should be taken into account in the design of web sites. 5.2 Suggestions for future researchers The main problem with this experiment was gathering enough subjects to participate in the experiment. The more subjects that are used in an experiment, the better the results reflect actual/realistic situations. Therefore, one suggestion would be to carry out the experiment on a larger group of users. Another suggestion would be to analyze the performance of the subjects on each and every task. The complexity of the questions would come into question in this case, and it might be a good idea to explore how that would affect the overall outcome of the experiment. |
