A friend of mine who works for Google is looking for people with vision impairments to participate in a study. Here's a message from her:
At Google, we are focusing heavily on making our products accessible for users who are visually-impaired. We are currently organizing a study for users with significant visual impairment to get feedback on the accessibility of our products. This feedback is invaluable so that we can continue to make our products better for users all over the world.
We have a study coming up tomorrow (September 15), consisting of a 30 minute visit to our San Francisco office. If you are interested in participating, please click on the link
$1. We then will get in touch directly with users who look like a good fit for the study. Please feel free to forward the link to others who may be interested, or have them contact me directly at brynatsai@google.com or 650-495-7588 for more information.
Thank you!
Edit: For people who aren't around SF or Mountain View, you can give comments on Google products here! https://www.google.com/accessibility/get-in-touch.html
