Lenovo has brought some of its latest prototypes to preview at its TechWorld 2024 press conference, most of which are, of course, AI-powered. To that end, the OEM's first AI mouse and "Home AI Brain" have been showcased alongside the new AI Buddy, touted to bring a futuristic, emoji-based interpersonal experience to the digital assistant world. They are joined by a glasses-free 3D solution for video conferencing.
