Today, Google announced Action Blocks, a new tool for people with cognitive disabilities. The system allows users and their caregivers to add Assistant commands to the home screen of Android phones and tablets. Each command is represented by a custom image and it can be controlled with just one tap. For instance, when a user taps an Action Block icon of a cab, the system might order a rideshare. The goal is to help some of the 630 million people with some form of cognitive disability live more independently.
