Retinal degeneration, a leading cause of blindness worldwide, is primarily characterized by
the dysfunctional/degenerated photoreceptors that impair the ability of the retina to detect …

Traditionally, research on vision focused on its role in perception and our cognitive life.
Except for the study of eye movements, which have been regarded as an information …

We propose a class of passive haptics that we call Sparse Haptic Proxy: a set of geometric
primitives that simulate touch feedback in elaborate virtual reality scenes. Unlike previous …

In 1899, RS Woodworth published a seminal monograph,“The Accuracy of Voluntary
Movement.” As well as making a number of important empirical contributions, Woodworth …

Background There is a relatively small body of research on the motor performance of
children with mild intellectual disabilities (MID) and borderline intellectual functioning (BIF) …

Evidence for a dichotomy between the planning of an action and its on-line control in
humans is reviewed. This evidence suggests that planning and control each serve a …

The two contrasting theoretical approaches to visual perception, the constructivist and the
ecological, are briefly presented and illustrated through their analyses of space and size …

Encountered-type haptic devices (EHDs) face a number of challenges when physically
embodying content in a virtual environment, including workspace limits and device latency …

Recently our group forwarded a model of speed-accuracy relations in goal-directed
reaching. A fundamental feature of our multiple process model was the distinction between …

It is well established that during the preparation and execution of goal-directed movements,
perceptual processing is biased towards the goal. Most of the previous work on the relation …
