![]() ![]() Personal Information Management (PIM) is an activity in which individuals organize personal (often digital) information for later retrieval. We conclude with suggestions for future computer systems design. We suggest that the preference for navigation may be due to the triggering of automatic object finding routines and lower dependence on linguistic processing. ![]() In contrast, search activates the left inferior frontal gyrus, commonly observed in linguistic processing. Using fMRI we provide an explanation for this phenomenon by demonstrating that folder navigation results in activation of the posterior limbic (including the retrosplenial cortex) and parahippocampal regions similar to that previously observed during real-world navigation in both animals and humans. Despite advances in search technology, users prefer retrieving files using virtual folder navigation, rather than the more flexible query-based search. When searching, users first generate a query specifying some property of the target file (e.g., a word it contains) and then select the relevant file when the search engine returns a set of results. In navigation, users move down their virtual folder hierarchy until they reach the folder in which the target item is stored. With personal computers, there are two main ways to retrieve files: hierarchical navigation and query-based search. Efficient storage and retrieval of digital data is the focus of much commercial and academic attention. ![]()
