Abstract

In one embodiment, an oral care system is disclosed that includes an oral care device and at least one programmable processor. The oral care device includes a head having a reference face, a light source, at least one orientation sensor generating orientation data corresponding to orientation measurements of the reference face during a freeform oral care routine, and at least one optical sensor generating optical sensor data representing optical feedback resulting from the light from the light source being incident upon sections of the oral cavity. The processor, based on the orientation data, determines which optical sensor data corresponds with which of the sections of the oral cavity. For each section of the oral cavity, based on the corresponding optical sensor data, the processor determines an oral care characteristic.

Dependent claims

An oral care system comprising:

an oral care device comprising:
a head having a reference face;
a light source configured to cause light to be incident upon sections of an oral cavity during a freeform oral care routine;
and
a plurality of sensors comprising:
at least one orientation sensor configured to generate orientation data corresponding to orientation measurements of the reference face during the oral care routine;
and
at least one optical sensor configured to generate optical sensor data representing optical feedback resulting from the light from the light source being incident upon the sections of the oral cavity, the optical feedback being reflected light or fluoresced light;
at least one programmable processor communicably coupled to the plurality of sensors, the at least one programmable processor configured to:
based on the orientation data, determine which optical sensor data corresponds with which of the sections of the oral cavity;
and
for each section of the oral cavity, based on the corresponding optical sensor data, determine an oral care characteristic.
