Visual field or retinotopic mapping is one of the most frequently used paradigms in fMRI. It uses activity evoked by position-varying high luminance contrast visual patterns presented throughout the visual field for determining the spatial organization of cortical visual areas. While the advantage of using high luminance contrast is that it tends to drive a wide range of neural populations – thus...
We introduce a new method for measuring visual population receptive fields (pRF) with functional magnetic resonance imaging (fMRI). The pRF structure is modeled as a set of weights that can be estimated by solving a linear model that predicts the Blood Oxygen Level-Dependent (BOLD) signal using the stimulus protocol and the canonical hemodynamic response function. This method does not make a priori...
This paper presents a virtual prototyping (VP) system for digital fabrication of automobile environment to facilitate rapid visibility evaluation. The system comprises a suite of software packages for image generation and hardware control processes, including driving environment simulation, vision examination, integrated with eye-tracking and position tracing system based virtual reality (VR) technology...
