This presentation will take a behind-the-scenes look at the development and launch of adaptive content on Alexa Devices, which uses computer vision to adjust the on-screen display based on how close you are to the device. When you’re close to the device, the content on the home screen changes to provide more detail. When you’re farther away, it changes to be more easily viewed from a distance. We will go into detail about the “working backward” process used for product development at Amazon. We’ll discuss the computer vision algorithms we utilized; key trade-offs between latency, accuracy and privacy; and how we came up with the right state logic and UI patterns to deliver a delightful customer experience.
