They revisit search results to re-find information and build an understanding of their search need through iterative explorations of query formulation. These tasks are not well-supported by search interfaces and web browsers. We designed and built SearchPanel, a Chrome browser extension that supports people in their ongoing information seeking. This extension combines document and process metadata into an interactive representation of the retrieved documents that can be used for sense-making, navigation, and re-finding documents. In a real-world deployment spanning over two months, results show that SearchPanel appears to have been primarily used for complex information needs, in search sessions with long durations and high numbers of queries. When process metadata was present in the UI, searchers in explorative search sessions submitted more and longer queries and interacted more with the SERP. These results indicate that the process metadata features in SearchPanel seem to be of particular importance for exploratory search.

Our solution has been implemented as a prototype for mobile use on a hand-held computer using Microsoft Pocket PC with a screen size of 240x320 pixels. The prototype uses the same in- formation as service engineers use

It is illustrated from our development ofa multi-modal information system for local bus timetableinformation. The system is based on a natural languageinterface for typed interaction that is enhanced to handlealso multi-modal interaction. The multi-modal userinterface was designed based on empirical investigationsand some results from these investigations are presented.We also show

However, little is known about how to design such a system that is suitable for the home environment. In this paper we explore possible error resolution strategies in the case of speech recognition errors in a TV-setting. From previous research two techniques have

We designed a query preview control that visualizes the distribution of newly-retrieved and re-retrieved documents prior to running the query. When evaluating the preview control with a control condition, we found effects on both people's information seeking behavior and improved retrieval performance. People spent more time formulating a query and were more likely to explore search results more deeply, retrieved a more diverse set of documents, and found more different relevant documents when using the preview.
