    Abstract: There is provided a device for rendering haptic feedback to a user and method for operating the device to render the haptic feedback to the user of the device. The device comprises a first part operable to apply a non-invasive action on a part of the body of the user and a second part operable to be held by the user and to render haptic feedback to the user. At least one sensor signal indicative of an interaction between the first part of the device and the 5 part of the body of the user is acquired (402). The acquired at least one sensor signal is processed to determine haptic feedback representative of the interaction between the first part of the device and the part of the body of the user (404). The determined haptic feedback is rendered to the user at the second part of the device (406).

    Abstract: There is provided a handheld personal care device, the device comprising one or more light emitting elements, each configured to emit light; one or more light receiving elements, each configured to receive light and output a respective measurement signal representing measurements of the received light; and a control unit that is configured to estimate a position and/or an orientation of the device relative to a subject; wherein the one or more light emitting elements and the one or more light receiving elements are arranged on the device such that, depending on the position and/or the orientation of the device relative to the subject, 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 reflected by a reflective surface in the environment of the subject; wherein the control unit is configured to estimate the position and/or the orientation of the device relative to the subject based on an analysis of the respective measurement signals of the one or more light receiving elements to determine, for each of the one or more light receiving elements, (i) whether the light receiving element has received light from at least one of the one or more light emitting element, and/or (ii) from which of the one or more light emitting elements the light receiving element has received light.
