If you want to be proactive about your own learning...
Use the "Discover your Assistive Technology" to explore AT in a focused way. You'll find videos, self-assessment selectors, and also offers a pathway to publish your own.
Us this to match your own personal 'challenge', with the devices you have access to, and identify matching technologies to better support your own needs.
If you use an AT tool that isn't included in the AT Hive you can submit an AT write up to AHEAD and they'll find the right place for it.
