We describe a virtual interactive surface technology based on a projector-camera system connected to a mobile device. This system, named mobile surface, can project images on any free surfaces and enable interaction in the air within the projection area. The projector used in the system scans a laser beam very quickly across the projection area to produce a stable image at 60 fps. The camera-projector synchronization is applied to obtain the image of the appointed scanning line. So our system can project what is perceived as a stable image onto the display surface, while simulta neously working as a structured light 3D scanning system.
We report on a symbolic-numeric algorithm for computing the Alexander polynomial of each singularity of a plane complex algebraic curve defined by a polynomial with coefficients of limited accuracy, i.e. the coefficie...

With a growing interest in Patent Information Retrieval, there is a need to better understand the context associated with patent users, their tasks, needs and expectations of patent search systems and applications. Patent search is known to be a complex, difficult and challenging activity, usually requiring expert Patent Information Specialists to spend a substantial amount of time sourcing (or not) documents relevant to their particular task. Information Retrieval provides a whole array of possible techniques and tools which could be applied to ease the burden of such retrieval tasks, and also make searching patents more accessible to non-Patent Information Specialists. In this paper, we report the findings from a survey of patent users conducted to ascertain information about patent users and their search requirements with respect to Information Retrieval systems and applications.
