Lack of timely access to information is a significant problem for the nearly 24 million blind or visually impaired (BVI) individuals in the U.S. and 285 million globally. Significant progress has been…
Assessing visual function is a fundamental aspect of eye research. However, existing tests often face limitations due to their design for in-clinic use, the necessity for trained personnel, time…
Artificial deep neural networks (DNNs) are used in many different ways to address scientific questions about how biological vision works. In spite of the wide usage of DNNs in this context, their…
Visual impairment refers to a condition where a person's eyesight cannot be improved with medical treatment. Such individuals face difficulties in performing daily living activities independently and…
Our eyes are never at rest. Between the microsaccadic eye movements and microfluctuations of the eye's autofocus mechanism (ocular accommodation), our visual system constantly encounters time-varying…
I will describe our research into a surprising visual illusion in which humans misperceive the shape of a highly familiar object in a highly familiar context: their own mobile phone while they hold it…
The efficacy of visual prostheses in object recognition is limited. While various limitations exist, here we focus on reducing the impact of background clutter on object recognition. We have proposed…
Walking, a fundamental human activity, presents challenges to visual stability due to motion blur induced by eye movements. The goal of my research is to elucidate the intricate relationship between…
Stereopsis – deriving information about distance by comparing views from two eyes – is widespread in vertebrates but so far known in only class of invertebrates, the praying mantids. Understanding…
Dual sensory impairment (DSI) refers to combined vision and hearing impairment. DSI concerns a large population and its prevalence increases drastically with age. In the US, it is estimated that 40%…
