We present first experiences from Local Area Artworks, a system enabling collaborative art interpretation on-site, deployed during an exhibition in a local art gallery. Through the system, we explore ways to re-connect people to local places by making use of their personal mobile devices as interfaces to the shared physical space. With a collocated collaborative writing system in the semi-publi...

In studies of cued recall, responses to photographic stimuli have often been examined in isolation related photography practices (e.g. taking, organising, or sharing images), and without considering how photographs are used. contrast, photo-elicitation methods position not simply as cues, but meaningful artefacts around which accounts the past constructed. Drawing on interviews, I examine recal...

A new photo-reactive polymer, polyvinylalcohol modified with phenylazido groups, was synthesized as a microarray matrix. The polymer is soluble in water and spin-coated onto glass plate. Aqueous solutions of proteins were micro-spotted onto the coated glass and were fixed by ultraviolet light irradiation. Subsequently, cell adhesion on the photo-immobilized protein microarray was investigated. ...

In this paper, we propose a system to detect event photos using geotagged tweets and non-geotagged photo tweets. In our previous work, only “geotagged photo tweets” was used for event photo detection the ratio of which to the total tweets was very limited. In the proposed system, we use geotagged tweets without photos for event detection, and non-geotagged photo tweets for event photo detection...

Let bd(P ) denote the boundary of a simple polygon P . Points p and q of P are mutually visible if segment pq lies entirely inside P . This notion of visibility gave birth to an extensive literature on art-gallery problems [3], concerned with guarding the floor of a polygonal art-gallery. Chvatal [2] showed that bn/3c point guards are always sufficient and sometimes necessary. Allowing guards t...
