Superimposition of oriented grating masks on vernier targets results in bimodal patterns of vernier threshold elevation, with peaks occurring on either side of vernier target orientation. These bimodal masking effects suggest a contribution to vernier acuity from spatial filters tuned to orientations on either side of the target. We report similar bimodal threshold elevation with plaid masks co...

Many visualization applications require digital displays and projectors with very high resolution, and one well-known technique to increase resolution is to spatially arrange several projected images in a tiling configuration. Less known is the fact that projectors also allow a very different type of solution, called “wobulation,” which is the superimposition of several projections, each shifte...

The aim of this study was to determine whether neuronal activity in the macaque supplementary eye field (SEF) is influenced by the rule used for saccadic target selection. Two monkeys were trained to perform a variant of the memory-guided saccade task in which any of four visible dots (rightward, upward, leftward, and downward) could be the target. On each trial, the cue identifying the target ...

Humans and other animals demonstrate the ability to perceive and respond to temporally relevant information with characteristic behavioral properties. For example, the response time distributions in peak-interval timing tasks are well described by Gaussian functions, and superimpose when scaled by the criterion duration. This superimposition has been referred to as the scalar property and resul...

Projector phones are starting to be marketed for business presentations and media viewing, and we have begun to document how people use them "in the wild." We have observed that, in addition to the expected uses, projector phones afford novel interaction modalities. A key observation is that users can readily exploit projector phones' new facilities to author effects employing superimposition, ...
