Hi! I enjoyed reading your blog post this week. Identifying and addressing potential barriers to the interactive resource, such as privacy concerns, shows attentiveness to user privacy, comfort, and security. I think it’s a great idea to give learners the option to not create a public account if they don’t feel comfortable, instead, these users can focus on navigating the privacy settings in more depth. I also like how you used transportation as an analogy for universal designs in engineering. The bus audios and visuals ensure those with accessibility impairments are able to understand the same as those without impairments. This analogy helps to demonstrate how important it is for us to have visual and audio recordings incorporated into our interactive learning design.
