#Echolocation tells absolute distances whereas the #AI depth view only gives relative distances (depth order), but still with supplemental absolute depth cues from changes in apparent size when moving to and fro, as well as effects of visual parallax when moving sideways.
"These findings will have implications for the training and uptake of sensory substitution and augmentation technology, as well as perceptual learning in general."

Many engineers believe basic science doesn't matter. Just make better devices. Optimize the signal. The biology is someone else's problem.
Except the biology is why every chronic neural interface eventually fails. You cannot engineer around a problem you refuse to study.

The accompanying image shows what the two AI depth view models make of a historic photo of a blind user of The vOICe for Android who won the Neurothlon 2018 blind navigation and object identification contest, at the time wearing $200 Chinese smartglasses.
Top: Photo from 2018 showing Vadim Artsev, blind user of The vOICe vision BCI and winner of the Neurothlon 2018 contest, talking with BCI expert Alexander Kaplan. Middle: Screenshot of AI depth view of the photo, using "good" model, toggled by key 'h'. Bottom: Screenshot of AI depth view of the photo, using "best" model, toggled by capital 'H'.
The vOICe for Android 2.82 is out! It bundles two monocular AI depth models in a trade-off between visual detail and CPU load: toggle one or the other by pressing key 'h' ("good model") or capital 'H' ("best model", higher CPU load) via soft keyboard play.google.com/store/apps/d... #BCI #blindness

Have there been any surveys on what blind people think of getting a Neuralink Blindsight brain implant or other brain implant for restoring vision? www.artificialvision.com/archive/chat... (ChatGPT output as PDF)
"A1 neurons did not show enhanced responses to unexpected stimulus repetitions, contrary to predictive-coding theory. However, they did show enhanced responses to unexpected stimulus omissions."
Neural responses to unexpected stimulus repetitions and omissions in auditory cortex provide mixed evidence for predictive coding www.biorxiv.org/content/10.6... via @neuroskeptic.bsky.social; #neuroscience
Funny: the human/monkey retina has ON & OFF (light, dark) detecting cells for responding to visual stimuli, the ear only ON cells for auditory stimuli, but now for unexpected auditory stimuli seemingly only OFF cells?
