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)
In this paper we present the results of a study of human preferences in using mid-air gestures for directing other humans. Rather than contributing a specific set of gestures, we contribute a set of gesture types, which together make a set of the core actions needed to complete any of our six chosen tasks in the domain of human-to-human gestural(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 outline a genealogy of Mixed Reality Lab (MXR) projects, their influencing factors both from the Asian region and also within the lab, the employment of "Blue-Sky Innovation" by the lab for ideation, collaboration and project generation, as well as discuss some major points of inspiration for MXR from various sources.
We refer to human-robot relationships as Lovotics. In this paper a design process for Lovotics is presented. In order to invoke these relationships, technological solutions can only take us so far. Design played an important role in order to engage users to explore the possibilities of bi-directional, human-robot love. We conducted a user-centric study in(More)
We present a new methodology based on ferromagnetic fluids in which the user can have direct interaction (input/output) through a tangible and malleable interface. Liquid Interfaces uses the physical qualities of ferromagnetic fluids in combination with capacitive, multi-touch technology, to produce a 3D, multi-touch interface where actuation,(More)
In this paper we analyze the works of the Keio-NUS CUTE Center at the National University of Singapore in order to uncover the dispositions of "analogness" and "digitalness" in regards to the relationship between users and interfaces. By comparing concepts of embodiment from a philosophical perspective, paired with the computer science treatment of analog(More)
We present an OUI that combines Hall Effect sensing and actuation through electromagnetically-manipulated ferrofluid. The movement of magnets worn on the fingertips, over a surface embedded with a Hall Effect sensor array and electromagnets, gives the user the ability to interact with ferrofluid. This system provides a three-dimensional, physically animated(More)
