Google is launching a major redesign of its Assistant app. The search giant's digital assistant was initially launched as a way for users to give commands using just their voice. But as digital assistants, including Google's own, begin to appear on a broader range of devices, it's meant that users are increasingly interacting with them using touch. In fact, more than half of interactions occur using touch, according to the firm. Google took notice and now it's making some helpful updates to the Assistant app as a result.
