As hordes of gadget fiends gather at the world’s biggest consumer tech show in Las Vegas, here are the key themes to expect from the event.

Voice assistants: Amazon’s Alexa was a standout of last year’s CES. This year many gizmos will feature voice control—and Alexa will do battle with Google’s own helper, Assistant.

Cars, cars, cars: The show has become increasingly auto-dominated in recent years. As driverless tech matures, expect sensors, onboard computers, software, and concept vehicles aplenty.

AI everywhere: The show has an AI marketplace for the first time. With machine-learning hype at fever pitch, expect almost every firm to shoehorn AI into products.

More AR, less VR: Pure virtual reality continues to be a hard sell to consumers. Expect to see firms offer more augmented-reality concepts this week.

More of the same: CES ain’t CES without huge TVs, rollable screens, and weird gadgets—right?
