What's inside HarmonyOS

  1. Overview of Sleep Apnea Detection Mechanism

    Sleep Apnea Detection on Huawei wearables is based on a combination of heart rate and blood oxygen monitoring; it is not based on snoring detection. It identifies apnea caused by complete or partial upper airway obstruction or reduced respiratory center drive, which can lead to chronic intermittent hypoxia, micro-awakenings, abnormal sleep structure, daytime sleepiness, memory decline, and autonomic nervous system dysfunction.

  2. Overview of Dolphin Sonar Communication

    Dolphin Sonar Communication allows divers to send preset text, emojis, and SOS distress signals to dive buddies underwater. Key technical constraints include:

    • Maximum communication range: 30 meters (can be extended to 60 meters if another watch with the feature enabled forwards the SOS signal).
    • Signal behavior: The watch emits a buzzer sound for 25 seconds during transmission.
    • Environment: Only works underwater or for short-distance testing in air; it does not support communication between air and water.

  3. Overview of Health Summary feature

    Health Summary is an application that tracks personal health changes based on multi-dimensional data analysis. It primarily monitors sleep quality, exercise duration, and stress levels, providing trend chart analysis and timely notifications.

    Key constraints and notes:

    • Reports are not generated daily; insufficient wear time or not wearing the device during sleep may prevent reports from triggering.
    • Data becomes visible on the watch after two consecutive days of wear; long-term use improves analysis accuracy.
    • The application is not medical software; results are not for medical diagnosis and should be used as a reference only.

  4. Overview of Health Summary feature

    Health Summary is an application that tracks personal health changes based on multi-dimensional data analysis. It primarily monitors sleep quality, exercise duration, and stress levels, providing trend analysis and notifications.

    Key constraints and caveats:

    • Reports are not generated daily; insufficient wear time or not wearing the device during sleep may prevent report triggers.
    • Data becomes visible on the watch after two consecutive days of wear; long-term use improves analysis accuracy.
    • This application is not medical software; results are for reference only and should not be used as a medical diagnosis.

  5. Overview of the Fusion Development Engine for HarmonyOS PCs

    The Fusion Development Engine allows developers on HarmonyOS PCs to run a Linux environment without requiring a virtual machine or dual-boot configuration. The current 1.0 release primarily supports the openEuler distribution and is designed to cover core development scenarios, though some functional limitations (such as systemctl support) may exist in the initial version.

    • Data becomes visible on the watch after two consecutive days of wear; long-term use improves analysis accuracy.
    • The application is not medical software; results are for reference only and should not be used as a medical diagnosis.

  7. Overview of Sleep Apnea detection mechanism

    Sleep Apnea detection is based on a combination of heart rate and blood oxygen monitoring, rather than snoring sounds. It identifies apnea caused by complete or partial upper airway obstruction or reduced respiratory center drive, which can lead to chronic intermittent hypoxia, micro-arousals, abnormal sleep structure, daytime sleepiness, memory decline, and autonomic nervous system dysfunction.

  8. Overview of Huawei Lingxi Floating Touch for MateTV

    Huawei Lingxi Floating Touch is a multi-finger interaction solution designed for the Huawei Vision MateTV series (standard on Pro versions). It allows users to control the screen using a virtual cursor by precisely identifying the 3D positions of the left and right thumbs in a floating touch area. This replicates smartphone and tablet interaction logic on a large screen, supporting tasks such as:

    • Fast paging, sliding, and content browsing.
    • Two-finger gestures for zooming and rotating images or maps, as well as photo editing.
    • Playing mobile games (e.g., competitive gaming, racing, and puzzle games).

  9. Overview of the HarmonyOS AI Technical Architecture

    The AI system uses a cloud-edge collaborative computing framework organized into four layers:

    1. Application Layer: Implements intelligent scene applications, voice assistants, and recommendations.
    2. Capability Layer: Provides core AI functions including Natural Language Processing (NLP), Computer Vision (CV), and Machine Learning (ML).
    3. Framework Layer: Powered by MindSpore, supporting distributed learning and cloud-edge synergy.
    4. Chip Layer: Hardware acceleration via NPU, neural networks, AI computing power optimization, and energy management.

  10. Overview of HarmonyOS Distributed Soft Bus and Device Connectivity

    HarmonyOS utilizes a new distributed soft bus with hardware-software-cloud synergy to improve cross-device connection speeds by up to 3x while reducing power consumption. It supports simultaneous connections for up to 4 devices, enabling features such as cross-device scanning, shared galleries, and a cross-device clipboard.

  12. Overview of HarmonyOS Core System Features

    HarmonyOS provides a set of native system capabilities focused on aesthetics, connectivity, intelligence, and security:

    • Native Aesthetics (原生精致): Implements a harmonious aesthetic order based on natural physical laws, featuring 'Gravity Animations' for seamless transitions from lock screen to unlock.
    • Native Connectivity (原生互联): Supports 'One-Touch Transfer' for sharing media and files, and cross-device interoperability (e.g., triggering a phone camera from another device).
    • Native Intelligence (原生智能): Features screen-aware dialogue, academic paper reading, knuckle-circle selection for image cutout/Q&A/shopping, and AI voice repair via 'Xiaoyi'.
    • Native Security (原生安全): Reduces privacy risks by prohibiting 9 categories of unreasonable permissions and implementing granular data access to minimize permission pop-ups.
    • Native Fluency (原生流畅): Optimizes system responsiveness, animation tracking, graphics acceleration for gaming, and overall application smoothness.
    • Native Applications (原生应用): Provides a new application market for high-quality, pure, and secure app downloads.
