Back in 2015, Lenovo showed off a laser projector built into a smartphone. Last year, the company revealed a flexible phone. At its Tech World 2017 summit, Lenovo showed off its latest concept products, and this time around, the manufacturer is focusing on AI.

First up is the CAVA, a smart assistant that relies on deep learning to build facial recognition systems and natural language understanding technologies to better understand your queries. CAVA learns based on your usage habits, and it can parse messages to serve up recommendations. For instance, if you have an upcoming calendar event, CAVA will analyze the weather and traffic data and suggest the ideal time to leave.

With SmartCast+, Lenovo is looking to go beyond the likes of Echo and Google Home by offering a smart speaker that recognizes sounds and objects. The speaker also has a built-in projector that delivers AR experiences by projecting images to a wall, with Lenovo looking at educational use cases for the device.

The DaystAR headset is an independent vision processing unit with free-formed surface lenses and a 40-degree field of view, offering untethered AR experiences built on Lenovo's own AR platform.
