Conference Paper
Nowadays video games are more inclusive: children, disabled people, and seniors are considered. However, there are players that require special configuration so they could enjoy playing equally. One of these types of players is left-handed players. In order to determine whether to create a special configuration designed for the needs of left-handed...

A fundamental task in the sorting of facial photographs is the modelling of pairwise facial similarity. A three-way analysis of facial similarity described in this work uses data obtained from card sorting of a set of facial photographs, done by a group of participants. Participants were asked to sort the photographs into an unrestricted number of...
Conference Paper
Full-text available
Card sorting was used to gather information about facial similarity judgments. A group of raters put a set of facial photos into an unrestricted number of different piles according to each rater's judgment of similarity. This paper proposes a linear model for 3-way analysis of similarity. An overall rating function is a weighted linear combination...

The card sorting problem involves the similarity judgments of pairs of photos, taken from a set of photos, by a group of participants. Given the lack of an objective standard for judging similarity, different participants may be using different strategies in judging the similarity of photos. It could be very useful to identify and study these strat...

As individuals are increasingly being called to act in environmentally-conscious ways, they will seek out any and all resources which might help to inform their actions. Unfortunately, a 2002 OECD report indicated that there seemed to be declining trust of environmental information sources and increasing confusion about which actions could be most...

Video games have become a driving force for innovation in many aspects of the entertainment industry and beyond. Since gaming may also be in a position to drive the emerging "maker movement", we consider the "DIY game industry". In this half-day course, attendees will be introduced to DIY Game Console construction and programming by building their...

There is a large gap between attitude and action when it comes to consumer purchases of ethical food. Amongst the various aspects of this gap, this paper focuses on the difficulty in knowing enough about the various dimensions of food production, distribution and consumption to make an ethical food purchasing decision. There is neither one universa...

In an open card sorting study of 356 facial photographs, each of 25 participants created an unconstrained number of piles. We consider all 63,190 possible pairs of photos: if both photos are in the same pile for a participant, we consider them as rated similar; otherwise we consider them as rated dissimilar. Each pair of photos is an attribute in a...

Facial recognition is routine for most people; yet describing the process of recognition, or describing a face to be recognized reveals a great deal of complexity inherent in the activity. Eyewitness identification remains an important element in judicial proceedings: it is very convincing, yet it is not very accurate. A study was conducted in whic...

Bruce Sterling defines spimes, in part, as extensively rich streams of data and information about things. From a theoretical viewpoint, the concept of spimes is indeed interesting, with seemingly endless possibilities for enriching our knowledge about the things all around us. In terms of our everyday decision-making activities, spimes could have s...
