pulse2percept: A Python-based simulation framework for bionic vision

Retinal degenerative diseases such as retinitis pigmentosa and macular degeneration result in profound visual impairment in more than 10 million people worldwide, and a variety of sight restoration technologies are being developed to target these diseases.

Retinal prostheses, now implanted in over 500 patients worldwide, electrically stimulate surviving cells in order to evoke neuronal responses that are interpreted by the brain as visual percepts (‘phosphenes’). However, interactions between the device electronics and the retinal neurophysiology result in perceptual distortions that may severely limit the quality of the generated visual experience:

Built on the NumPy and SciPy stacks, pulse2percept provides an open-source implementation of a number of computational models for state-of-the-art visual prostheses (also known as the ‘bionic eye’), such as ArgusII, BVA24, and PRIMA, to provide insight into the visual experience provided by these devices.

Simulations such as the above are likely to be critical for providing realistic estimates of prosthetic vision, thus providing regulatory bodies with guidance into what sort of visual tests are appropriate for evaluating prosthetic performance, and improving current and future technology.

Installation

Once you have Python 3 and pip, the stable release of pulse2percept can be installed with pip:

pip install pulse2percept

The bleeding-edge version of pulse2percept can be installed via:

pip install git+https://github.com/pulse2percept/pulse2percept

When installing the bleeding-edge version on Windows, note that you will have to install your own C compiler first. Detailed instructions for different platforms can be found in our Installation Guide.
