The main purpose of this study was to investigate the root and canal morphology of Sri Lankan mandibular molars and to determine the affinities of these morphological variations to those of people of European and Asian origin. Two hundred mandibular first and second molars were examined. The number of roots and the prevalence of C-shaped (gutter-shaped)(More)
Huggy Pajama is a novel wearable system aimed at promoting physical interaction in remote communication between parent and child. This system enables parents and children to hug one another through a novel hugging interface device and a wearable, hug reproducing pajama connected through the Internet. The hugging device is a small, mobile doll with an(More)
The pervasiveness of computing has extended into domestic realms, including the dining room. Beyond simply a place to consume food, the dining room is a social hub where family members meet and share experiences. Yet busy lifestyles can make it difficult to spend social time with your family. To provide a new solution for family bonding, this paper presents(More)

Families have strong desires to have fun together, even at a distance. "Food Media" is an exploration of appropriating food and food activities as a medium for family communication and entertainment, across generations and over a distance. Traditionally, food has always been a social hub which brings people together for communication and entertainment. As(More)
In this paper we present zSense, which provides greater input expressivity for spatially limited devices such as smart wearables through a shallow depth gesture recognition system using non-focused infrared sensors. To achieve this, we introduce a novel Non-linear Spatial Sampling (NSS) technique that significantly cuts down the number of required infrared(More)
In this paper we propose a new technology of touch sensitive textile displays that can detect touch without adding additional sensors to a thermochromic inks and peltier semi-conductor display system. Without any changes to the hardware of the display, we present a method to modify the existing temperature controllers of pelter elements to detect impulse(More)
Interactive media not only should enhance human-to-human communication, but also human-to-animal communication. We promote a new type of media interaction allowing human users to interact and play with their small pets (like hamsters) remotely via Internet through a mixed-reality-based game system " Metazoa Ludens ". To examine the systems effectiveness:(More)
