Exploring the impacts of adverse phosphene phenomena in synthetic vision
Jake Thomas
A realistic take on the state of synthetic vision.
This project aims to look at the current state of prosthetic vision and explore the outcomes that might be possible for patients requiring this technology. Through a psychophysics experiment testing both mobility and letter recognition tasks, this project uses current standards to determine the performance that someone might realistically be able to achieve.
In addition to this, the often idealised model of a uniform map of homogenous phosphenes was contrasted against the performance of a more realistic map with irregular phosphenes. The uniformity of these maps was also explored as a possible source of performance discrepancy as this information could be useful to a practitioner when assessing the innate performance ceiling that a patient might have with these kinds of tasks.

By adopting a more realistic approach to the current state of prosthetic vision, including limited map resolution, grid randomness and adverse phosphene phenomena, it is hoped that more papers on the topic will aim towards assisting those with current and soon to be released implants, despite the infancy of the field as a whole.
