Searching for Mobile Intruders in a Polygonal Region by a Group of Mobile Searchers
- SIAM JOURNAL ON COMPUTING
"... The problem of searching for mobile intruders in a polygonal region by mobile searchers is considered. A searcher can move continuously inside a polygon holding a flashlight that emits a single ray of light whose direction can be changed continuously. The visibility of a searcher at any time instant ..."

The Information Needs of Mobile Searchers: A Framework
"... The growing use of Internet-connected mobile devices demands that we reconsider search user interface design in light of the context and information needs specific to mobile users. In this paper the authors present a framework of mobile information needs, juxtaposing search motives—casual, lookup, l ..."

On the Minimum Node Degree and Connectivity of a Wireless Multihop Network
- ACM MobiHoc
, 2002
"... This paper investigates two fundamental characteristics of a wireless multihop network: its minimum node degree and its k–connectivity. Both topology attributes depend on the spa-tial distribution of the nodes and their transmission range. Using typical modeling assumptions — a random uniform distri ..."

CiteSearcher: A Google Scholar
"... Google Scholar is an invaluable resource in a quickly expanding digital world with an estimated 50,000,000 scholarly articles in existence. It lets one search for scholarly articles by title, author names, publishing venues, and keywords. Their web-based interfaces work great on desktop/laptop scree ..."

/laptop screens with 1024x768 resolution or better. However, many mobile devices such as phones and tablets have lower resolutions, with some being as low as 320x480. In order to support such low resolution devices, we have developed CiteSearcher, a front-end application for iOS and Android mobile devices, which
Searching a Polygonal Room with One Door by a 1-Searcher
, 2000
"... The 1-searcher is a mobile guard whose visibility is limited to a ray emanating from his position, where the direction of the ray can be changed continuously with bounded angular rotation speed. Given a polygonal region P with a specified boundary point d, is it possible for a 1-searcher to event ..."

A large scale study of european mobile search behaviour
- In Proceedings of MobileHCI ’08
, 2008
"... Recent evidence suggests that mobile search is becoming an in-creasingly important way for mobile users to gain access to on-line information, especially as off-portal content continues to grow rapidly. In this paper we study the characteristics of mobile search by analysing approximately 6 million ..."

individual search requests generated by over 260,000 individual mobile searchers over a 7-day period during 2006. We analyse the patterns of queries used by mobile searchers and focus on key characteristics such as the click-thru rates of mobile searches in order to understand, for the first time, just how

Visibility-based pursuit-evasion with limited field of view.
- The International Journal of Robotics Research,
, 2006
"... Abstract We study a form of the pursuit-evasion problem, in which one or more searchers must move through a given environment so as to guarantee detection of any and all evaders, which can move arbitrarily fast. Our goal is to develop techniques for coordinating teams of robots to execute this task ..."

To this end, we introduce a new class of searcher, the φ-searcher, which can be readily instantiated as a physical mobile robot. We present a detailed analysis of the pursuit-evasion problem using φ-searchers
ABSTRACT Evaluating Interfaces for Intelligent Mobile Search

mobile search engines are unlikely to offer an adequate service for mobile searchers. Most borrow traditional query-based search and list-based result presentation formats from Web search and as such are not well optimised for the input and display features of mobile devices. For example, many simply
