Lenovo is also working on an AI assistant called CAVA that can manage your calendar. The company gave it facial recognition and context awareness functions to be able to accomplish its three primary tasks. First, it uses its deep learning-based face recognition technology to hide the contents of messages on the lock screen unless it's the registered owner who's looking at the device. Once CAVA has ensured that it's the owner using the phone, it also allows the user to add events to the calendar straight from the lock screen. Finally, the assistant's context awareness functions allow it to make recommendations and adjust events automatically. It can, for instance, tell the user when to leave the house for an appointment after analyzing weather and traffic into. At the moment, CAVA is a research prototype for China, and it's unclear if Lenovo has plans to make it available elsewhere.

One of the last two concepts Lenovo showed off is the SmartVest, an ECG-equipped piece of clothing that can monitor your heart rhythm 24/7. The other one is the Xiaole customer service platform that can learn from interactions with customers in order to make each conversation more natural and personalized.
