History-based Route Recommendation on Public Displays

Public displays are expected to compensate for the shortcomings of mobile web search. They have a major advantage in their large screen size and touch-based interaction that supports use by multiple people, but some end users, such as elderly people, lack the skills to formulate queries that retrieve the information they want from the Internet. In this paper, we highlight an important aspect of public displays: their role as an interaction medium for social communication. Since users of a public display are likely to share interests in the local area, search queries and results can be reused in future searches. Our approach aims to assist end users’ point-of-interest searches by providing local content composed of knowledge mashed up from web services and the local search history. As a proof of concept, we developed a map-based tourist navigation service and conducted preliminary experiments. In the experiments, we analyzed the subjects’ interaction processes in detail and identified design issues for further improvement, such as how to present the search history.
