Inertial sensor fusion algorithms: UnileverRecent Research Landscape

Inaccurate brush positioning leads to poor oral hygiene outcomes and user frustration. These innovations utilize synchronized sensor data to map appliance movement for precise real-time guidance.

What technical problems is Unilever addressing in Inertial sensor fusion algorithms?

Inadequate posterior dental access

(4)evidences

Standard linear brush geometries fail to reach difficult molar surfaces and gingival margins. Improved reach reduces plaque accumulation in hard-to-access oral regions.

Inaccurate intraoral spatial tracking

(4)evidences

User error and sensor drift during personal care activities lead to unreliable spatial data. Precise tracking ensures effective hygiene coverage and corrective feedback.
