Abstract
A skincare device includes a brushhead; a body including a motor assembly configured to oscillate the brushhead and an inertial measuring unit (IMU) configured to determine kinematic measurements of the device; a first optical encoder including a light source and an optical sensor configured to capture images; and processing circuitry configured to determine a location of the brushhead with respect to a body part of the user based on a combination of data measured from the IMU and the first optical encoder.
