The Huawei Watch Ultimate uses a stress tracking system that is integrated into its overall health monitoring capabilities. While specific details about the exact algorithms used for stress tracking are not explicitly mentioned, the watch relies on heart rate variability (HRV) to calculate stress levels. This is a common method used in many wearable devices to assess stress by analyzing variations in heart rate.
To track stress, the Huawei Watch Ultimate requires users to enable the "Automatic stress test" feature in the Huawei Health app. Once enabled, the watch will automatically run stress tests every 30 minutes when the user is at rest, adjusting the interval if the user is engaged in exercise[3]. The stress test feature involves calibrating the stress level by following on-screen instructions in the Huawei Health app[6].
The Emotional Wellbeing app on the watch provides tips and tricks to manage stress, including reminders to perform breathing exercises if negative thinking or stress is detected[9]. However, the stress test feature is not available on all Huawei devices, such as the GT Series[6].
In terms of technology, the Huawei Watch Ultimate uses advanced sensors like eight photoelectric sensors and two groups of light sources, along with an upgraded AI algorithm and a curved glass lens, primarily for heart rate monitoring[7][9]. While these technologies enhance heart rate accuracy, they indirectly support stress tracking by providing precise physiological data that can be used to assess stress levels.
Overall, while the specific algorithms for stress tracking are not detailed, the Huawei Watch Ultimate's stress monitoring system is part of its broader health and wellness features, leveraging HRV and user activity data to provide insights into stress levels.
