-OpenHarmony is an open-source project launched by the OpenAtom Foundation and serves as an open-source, distributed operating system (OS) that is intended to address all conceivable usage scenarios. OpenHarmony is an open-source version of HarmonyOS. HarmonyOS is a future-proof distributed operating system open to you as part of the initiatives for the all-scenario strategy, adaptable to a mobile office, fitness and health, social communication, and media entertainment, and so on. Unlike a legacy operating system that runs on a standalone device, HarmonyOS is built on a distributed architecture designed based on a set of system capabilities. It is able to run on a wide range of device forms, including smartphones, wearables, tablets, PCs, smart TVs, AI speakers, head units, earphones, and AR/VR glasses.
