The present study examined how the availability of and alterations in sensory information during the sensory organization test (SOT) influenced the amount, variability, and temporal structure of spontaneous postural sway in young, healthy adults. Findings indicated that postural sway tended to increase in amount and variability as the SOT condition became(More)
The authors investigated the multisensory control of posture by altering sensory information across the visual and somatosensory systems. The support surface and visual surround were sway-referenced to anterior/posterior center of mass sway and the gain between postural sway and degree of sway referencing was manipulated (gain settings were 0.2, 1.0, and(More)
Quantum computations that involve only Clifford operations are classically simulable despite the fact that they generate highly entangled states; this is the content of the Gottesman-Knill theorem. Here we isolate the ingredients of the theorem and provide generalisations of some of them with the aim of identifying new classes of simulable quantum(More)
OBJECTIVE To establish reliability estimates of the 75% Limits of Stability Test (75% LOS test) when administered to community-dwelling older adults with a history of falls. DESIGN Generalizability theory was used to estimate both the relative contribution of identified error sources to the total measurement error and generalizability coefficients. A(More)
<i>ColourNet</i> is a digital art system composed of a set interactive and interacting artworks. Although the artworks are able to work independently, they can also operate together to provide enhanced possibilities for human interaction and creative participation. We describe the <i>ColourNet</i> digital art system and demonstrate how people can interact(More)
At CHI2015 our Art.CHI initiative led to a two-day workshop, an art catalog and presentations during Interactivity. The long-term plan is to turn this into a regular feature of CHI. For CHI2016 we will additionally use a gallery space within the Conference concourse. This workshop will invite digital artists to present their work, discuss its immediate(More)
<i>Dropsketch</i> is a Smartphone drawing system that enables users to anonymously create and share simple black and white sketches of their surroundings. The free app, available for iPhone and Android devices, contains an easy-to-use sketching tool and the facility to 'drop' completed sketches on a shared map. It makes use of the Smartphone's built in(More)
