Lenovo's new AI-powered concepts include a virtual assistant Pocketnow

Whatever happened to Lenovo's crazy bendable gadget prototypes envisioned as tablet/smartphone hybrids and phone/smart bracelet crossbreeds? How about the company's fashionable smart shoes, which were also showcased at last year's Tech World "global event" in (extremely) early pre-release form? We're guessing both groundbreaking projects have either been abandoned or they need several more years of R&D work, and the same probably goes for a fresh batch of concept devices unveiled at the third annual Lenovo Tech World "innovation summit." After all, it's not too ambitious of Lenovo to think it can throw its hat in the digital assistant ring before long. CAVA, aka the Context Aware Virtual Assistant, makes a customarily sophisticated (read vague) promise of taking "deep learning" to the next level, leveraging "natural language understanding technologies to manage calendar events and remind you based on your habits."
