Embodiment Construction

[0054] The position and / or orientation of the handheld personal care device (such as a razor or toothbrush) relative to the subject changes as the subject uses the handheld personal care device. For example, when the handheld personal care device is used on the left side of the subject's face, the shaver may be in a first orientation and position; and when the handheld personal care device is used on the right side of the subject's face, the shaver may be In the second orientation and position. In addition, many handheld personal care devices, such as shavers and toothbrushes, are used by subjects while they are standing in front of a reflector.

[0055] The techniques presented in this document for estimating the position and / or orientation of a handheld personal care device relative to a subject utilize knowledge of the typical orientation and / or position of a handheld personal care device during use by a subject (including user or subject knowledge of how to hold a handhel...

Abstract

A handheld personal care device is provided, the device comprising one or more light emitting elements, each light emitting element configured to emit light; one or more light receiving elements, each light receiving element configured to receive light and output a signal representing the receiving a corresponding measurement signal of the measurement of light; and a control unit configured to estimate the position and / or orientation of the device relative to the object; wherein one or more light-emitting elements and one or more light-receiving elements are arranged on the device, so that depending on the position and / or orientation of the device relative to the object, at least one of the one or more light receiving elements can receive light emitted by at least one of the one or more light emitting elements and be light reflected by reflective surfaces in the environment of the object; wherein the control unit is configured to estimate the position and / or orientation of the device relative to the object based on an analysis of corresponding measurement signals of the one or more light receiving elements, for said Each of the one or more light receiving elements determines whether: (i) the light receiving element has received light from at least one of the one or more light emitting elements, and / or (ii) From which of the one or more light emitting elements the light receiving element has received light.

Description

technical field [0001] The present invention relates to a handheld personal care device, such as a shaver or toothbrush, and techniques for estimating the position and / or orientation of the handheld personal device relative to an object. Background technique [0002] It is contemplated that handheld personal care devices such as electric razors, shavers, toothbrushes (electric and non-electric), air flossing devices, skin treatment applicators, facial cleansers, eye energizers, epilators, etc., Will begin to provide more meaningful interactions between users and devices. The popularity of "connected products" (eg, products that are connected to the Internet or a home network) is increasing, and these products have sensing capabilities to generate data about the use or operation of the product. By utilizing data already available, the functionality of handheld personal care devices can be improved. Solutions can be personalized, adapt to the moment, and will create improved...
