Abstract: Systems, methods, and devices for providing feedback to an individual based on brushing performance, and providing guidance for the individual's brushing, are provided herein. In one exemplary embodiment, after an oral hygiene device is orientated, a determination is made as to a segment within the individual's mouth that a brush head of the oral hygiene device is located. Upon this determination being made, a sub-segment within the individual's mouth where the brush head is located is also determined. A brushing performance within the sub-segment is calculated and displayed to the user. A level of compliance for the particular segment is determined based on the brushing performance of the various sub-segments within the particular segment. If the level of compliance exceeds a pre-set compliance level for that segment, the individual is guided to a different segment within their mouth for brushing.

Abstract: A touch sensor input device includes a first and second array of electrodes, the electrodes in the first array being orthogonal to the electrodes in the second array. A capacitor sensing arrangement senses an electrode capacitance signal which varies in the presence of a touch input.

This arrangement has electrodes with a finer resolution than the sensing resolution, and this gives improved ability to sense accurately the position of the touch input.
