Thanks Bettina Fliegel for the insight! It does need more innovation in both products and wearing assistance process here if we want to offer more complicated devices. One thing I'm thinking about is to leveraging data collected from the app that mentioned above. General information can be found such as weight, height, blood type, etc. Then we can come up with solutions to calculate the expected device details as a suggestion to guide users to get the right shareable device.
Thanks Kate Rushton ! This is very helpful. It seems like more access to devices can greatly solve the problem ( decrease falls by%85). And the idea mentioned about donating, cleaning, and adjusting devices actually allow more effort and innovation.
