A nuanced understanding of the strategies that people who are blind or visually impaired employ to perform different instrumental activities of daily living (iADLs) is essential to the success of future visual accessibility aids.

What do visual prosthesis users see, and why? Clinical studies have shown that the vision provided by current devices differs substantially from normal sight.

Embedding simulated prosthetic vision models in immersive virtual reality allows sighted subjects to act as virtual patients by “seeing” through the eyes of the patient.

How are visual acuity and daily activities affected by visual impairment? Previous studies have shown that vision is altered and impaired in the presence of a scotoma, but the extent to which patient-specific factors affect vision and quality of life is not well understood.

How do people’s navigatioal abilities change in stressful conditions? How can we best train them for these situations? And how can vision augmentation be employed to improve situational awareness?
