### Software: from pulse to percept
Implemented as open-source software: http://github.com/uwescience/pulse2percept
--
Technical challenge:
--
- Retina modeled at 25 `\(\mu m\)` resolution
--
- Pulse-trains modeled at 5 `\(\mu sec\)` resolution
--
- 3 second movie `\(\rightarrow \)` `\(7.5 x 10^{12}\)` elements
--
#### Solution: parallelize and compute on Amazon Web Services
---
### A "virtual patient"
The software can simulate the percepts evoked by any stimulus
