We take some data with subjects of normal vision, and the data with low vision readers is gathered at the SUNY College of Optometry, where the experimental protocols are designed. A list of the project's publications is here . We will test the effect of several typographic and visual factors on reading which have not been previously studied. The choice of parameter values of typefaces to be tested will be guided initially by available empirical and theoretical work concerned with letter detection and discriminability. Three VDT reading methods will be evaluated for relative reading speed, comprehension, and subject acceptance.

In subjects with normal vision, we will simulate a variety of conditions that are characteristic of low vision patients. The aim is to determine which typographic variants best survive the simulated degradations, with each reading method, and to suggest conditions in which to test low vision patients. The aim is to provide guidance to low vision patients and practitioners in the selection of reading methods and text characteristics to use for vision rehabilitation. In both normal and low vision subjects, we will investigage the feasibility for people to read quickly and effectively with RSVP text, for extended passages and periods of time. The aim is to determine if these methods may be of practical use for routine reading.
