ThumbReels: query sensitive web video previews based on temporal, crowdsourced, semantic tagging

During online search, the user's expectations often differ from those of the author. This is known as the "intention gap" and is particularly problematic when searching for and discriminating between online video content. An author uses description and meta-data tags to label their content, but often cannot predict alternate interpretations or appropriations of their work. To address this intention gap, we present ThumbReels, a concept for query-sensitive video previews generated from crowdsourced, temporally defined semantic tagging. Further, we supply an open-source tool that supports on-the-fly temporal tagging of videos, whose output can be used for later search queries. A first user study validates the tool and concept. We then present a second study that shows participants found ThumbReels to better represent search terms than contemporary preview techniques

Nudge; don't judge:using nudge theory to deter shoplifters

Crimes defined as “acts attracting legal punishment” are injurious to the community because they violate moral rules (Blackburn, 1993). However, not all crimes are deemed worthy of a custodial sentence. For example, the criminal act of shoplifting usually only results in jail time for repeated offences (Doughty, 2006). And research indicates that the threat of imprisonment may not be an effective deterrent for potential shoplifters (Gonnerman, 2004). The notion that shoplifting is detached from the victim (Wilkes, 1978, Ecenbarger, 1988) and common to all socioeconomic classes affords the perception that shoplifting is a “victimless crime” to many. In this paper we suggest an alternative approach to tackling the problem. We examine whether deterrents engaging ‘nudge theory’ (Thaler and Sunstein, 2008) can discourage shoplifting. We review ‘design against crime’ literature and compare case studies to explore a new approach to preventing crime, using nudge as a theoretical framework. Our paper discusses how ‘rationality’ may influence criminal behaviour; that individuals indulge a “moment” of rational thinking before acting and how contemporary ‘design against crime’ techniques manipulate this thought-process to deter criminal behaviour. We argue that ‘nudge theory’ provides an interesting antithesis. To design against shoplifting using the theory of “nudge” we assert that people make choices non-rationally and can be deterred from situational crimes by designing environments with different contextual cues (Bonell et al., 2011) that deter crime. We call upon the design research community to discuss; debate and design with nudge theory as a preventative approach to shoplifting
