Perceptual learning improves detection and discrimination of relevant visual information in mature humans, revealing sensory plasticity. Whether visual perceptual learning affects motor responses is unknown. Here we implemented a protocol that enabled us to address this question. We tested a perceptual response (motion direction estimation, in which(More)
Perceptual skills can be improved through practice on a perceptual task, even in adulthood. Visual perceptual learning is known to be mostly specific to the trained retinal location, which is considered as evidence of neural plasticity in retinotopic early visual cortex. Recent findings demonstrate that transfer of learning to untrained locations can occur(More)
Most low vision people have functional vision and would likely prefer to use their vision to access information. Recently, there have been advances in head-mounted displays, cameras, and image processing technology that create opportunities to improve the visual experience for low vision people. In this paper, we present ForeSee, a head-mounted vision(More)
Practice can improve visual perception, and these improvements are considered to be a form of brain plasticity. Training-induced learning is time-consuming and requires hundreds of trials across multiple days. The process of learning acquisition is understudied. Can learning acquisition be potentiated by manipulating visual attentional cues? We developed a(More)
Visual impairments encompass a range of visual abilities. People with <i>low vision</i> have functional vision and thus their experiences are likely to be different from people with no vision. We sought to answer two research questions: (1) what challenges do low vision people face when performing daily activities and (2) what aids (high- and low-tech) do(More)
Visual search is a major challenge for low vision people. Conventional vision enhancements like magnification help low vision people see more details, but cannot indicate the location of a target in a visual search task. In this paper, we explore visual cues---a new approach to facilitate visual search tasks for low vision people. We focus on product search(More)
GOAL Training improves visual discrimination and detection (perceptual learning). Recently, we found that training on an estimation task leads to increased overestimation of motion directions from a boundary (Szpiro, Spering&Carrasco, Perceptual learning modifies untrained pursuit eye movements. Journal of Vision, 2014). Thus, two different training(More)
