Abstract
A device for providing an indication of brushing activity of a toothbrush comprises an accelerometer configured to produce acceleration data from motion of the toothbrush, and components for filtering the acceleration data to produce gravitational components and filtering the acceleration data to produce linear acceleration components. The device further comprises a component for projecting the gravitational components and the linear acceleration components into an n-dimensional space, where and for performing a clustering process on the projections of gravitational components and linear acceleration components into n-dimensional space to produce clustering results. The clustering results comprise a plurality of clusters each of which represents a brushing area. A brushing area can be determined based on an assignment of subsequent gravitational components and linear acceleration components of acceleration data to a particular cluster, and feedback provided to a user based on the determination of brushing area, thereby providing indication of brushing activity.
