Hi, you are making a good point. We are aware of the capability of screen readers reading OCR images and non exisiting visually memory. Our work sets up on this paper "Making memes accessible"
$1. It elaborates a technical approach to set up a database with sounds + alt text + text to speech to keep the inherited emotion of a meme (unlike screen readers). However this is only the technical side and lacks an user interface. We are also aware about design principles and have done a lot literature research... However this interface seems to be something new, thus we want to carry out a user study and eventually have the participants evaluate the final product.
