I am very interested in these open questions. Some I have conducted literature reviews on, some I have discussed with stakeholders through interviews/chats, some are pain points collected from online discussion, and some are inconveniences that I personally complain about and want to redesign. They constantly linger in my mind, waiting for the day they intersect with a technology and are solved. So if you have any ideas, please don’t hesitate to contact me. I am looking forward to your insights and solving these issues together.
