A New Approach to Voice User Interfaces – Chatbots Magazine

I was very much involved in the development of Mobile phone user interfaces 15 years ago. One of the struggles we had was the assumption, at the time, that you could just modify existing PC based interfaces by changing the size of the UI components, but keeping everything else the same. This incorrect approach lasted nearly 5 years. Eventually it was realised Mobile UIs had to be designed from scratch and hey presto, these simplified and easy to use interfaces could then be used on PC interfaces with few changes (and they were better than the original)-- this approach was called Mobile First design. It really only became obvious once Mobile began to dominate usage.
