  • In order for simulation results to translate to real prosthesis patients, simulations should rely on psychophysically validated phosphene models and employ a restricted field of view that necessitates head scanning.

    “In order for simulation results to translate to real prosthesis patients, simulations should rely on psychophysically validated phosphene models and employ a restricted field of view that necessitates head scanning (Kasowski and Beyeler, 2022).”

  • In a recent systematic review, the authors showed that although there is no shortage of publications demonstrating proof-of-concept augmentation strategies, less emphasis has been placed on understanding the usability of their proposed technology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
