Smart Ear-worn Device Algorithm
SMA Watch combines 6-axis head-tracking sensor fusion with 3D spatial audio for 5.1 and 7.1 content. As the listener moves, the soundstage responds to head motion for a more natural, immersive experience across video, music and gaming.

SMA Watch supports customizable head-gesture controls—including nodding, shaking and turning—to let users manage music, calls and other actions without reaching for their device.

With double- and triple-tap gestures, SMA Watch enables intuitive control of playback, volume, calls and voice-assistant functions for a faster, more seamless interaction.

For open-ear earbuds with a symmetrical form factor, SMA Watch identifies left and right wear orientation and automatically maps the correct audio channel. Users can pick up either earbud and wear it naturally.

SMA Watch automatically recognizes activity states such as resting, walking and running, then adapts the audio experience to the wearer’s current context.

SMA Watch monitors neck load and posture patterns to support long-term neck health insights. When prolonged head-down work or gaming is detected, the system records posture data and can deliver timely reminders alongside guided relief content.

SMA Watch delivers core fitness metrics—including steps, cadence, stride length, distance and calories—to help users understand daily activity across outdoor runs and indoor workouts.

SMA Watch detects when the wearer has fallen asleep and, based on preset preferences, can pause audio and transition the device into a sleep-ready mode for a more comfortable listening experience.

When an earbud is unexpectedly dropped, SMA Watch can issue an alert to help prevent loss. If there is no response within a defined time window, the system can identify a potential emergency and initiate the user-configured emergency contact workflow.
