Evidence for the proposition that human time perception is determined by an internal clock is largely indirect. It would strengthen the case for this hypothesis if a model for the internal clock were available from which predictions could be derived and tested, and if the basic parameter of such a model, the frequency at which the clock runs, could be(More)
By investigating the visual processing involved when saccades are made to newly appearing targets, we show that this processing is significantly nonlinear and that texture boundary information predominates. We used the global, or center-of-gravity, effect whereby a saccadic eye movement directed to a target consisting of a pair of elements has an amplitude(More)

Current methods for figure animation involve a tradeoff between the level of realism captured in the movements and the ease of generating the animations. We introduce a motion control paradigm that circumvents this tradeoff-it provides the ability to generate a wide range of natural-looking movements with minimal user labor. Effort, which is one part of(More)
Project Summary The computing environments of the future will involve large numbers of small and inexpensive devices, communicating with each other and interacting with their physical surroundings to accomplish a task. We propose to develop the programming languages, tools and methods necessary to produce robust, scalable and resource-efficient programs for(More)
The effect upon the detectability of narrow bars of ideal low-pass and high-pass filters was investigated. The results indicate that for optimum detection of the stimulus, spatial frequency components up to about 10 c/deg need to be transmitted. Two models (a multi-channel model, incorporating probability summation across spatial frequency, and a Grating(More)
The effect upon the detectability of broad bars and a sharp edge of ideal low- and high-pass filters was investigated. The results indicate that, for optimum detection of the stimulus, spatial frequency components up to about 5 c deg-1 need to be transmitted. Two models (a multi-channel model, incorporating probability summation across spatial frequency,(More)
