Report: Apple's major update on three wearable devices including AI glasses.

Apple Inc. is accelerating the development of three new wearable devices. This is part of its transition to AI-driven hardware strategy, with OpenAI and Meta Platforms Inc. also competing in this field. According to sources, Apple is ramping up its research and development investment in smart glasses, a wearable accessory that can be worn on shirts or as a necklace, and AirPods with enhanced AI capabilities. These three devices will all be built around the Siri digital assistant, which will rely on visual context to carry out relevant commands. Each product will be interoperable with Apple's iPhone and will rely on a set of different camera systems.
