Hi Jinwei, I found it quite beneficial that you recommended an application that can help non-native English speakers translate and comprehend the material from your learning resource. I think that it is a great idea to create an accessible resource and I hope that the application supports multiple languages. However, I was wondering how your group has adapted to learners that have colour blindness. Does the Ding Talk application help with describing images that have colour? Or does your resource apply a different solution to assist learners with colour blindness?
