Visual Interfaces Designed for Searching Text Content on Mobile Devices

Todd Welch, Gregory Short, and Beomjin Kim
Abstract—The widespread availability of mobile devices has made information available to many on the go, making it a valuable tool in everyday life. Their ability to look up information on the fly and assist with a user's information retrieval in a timely fashion make them a natural everyday carry. However, a limitation of these devices is the lack of screen space available to display information, thus presenting a potential problem to this seemingly ideal device. A technique to present a large amount of information, cohesively, is required to make users’ search activities more convenient and effective. We present visualization techniques designed for presenting lengthy text-based documents on mobile devices. The system uses two different visualizations, Overview and Detail. The Overview shows the overall profile of search terms in the document(s). The Detail View presents the requested information, clearly displaying to the user what content is available. By utilizing this two step approach, we can assist users' search activities by making them more effective in their search concerning lengthy text contents. A pilot experiment was conducted to evaluate the effectiveness of these visual interfaces compared to a traditional text-based interface. For a majority of measured items, the testers showed a higher degree of satisfaction using the visualization, that was developed to address the difficulties in exploring text content on a small screen device. Although a larger scale usability test is expected in the near future, our initial study shows the feasibility of using multi-level visual interfaces as a search-supporting tool to review lengthy text documents on mobile devices.

Index Terms—Visual interfaces, visualization, mobile devices, text content search.
