The present application relates to a shaving guidance system () for guiding a user during a shaving procedure, the system comprising an image sensor () configured to register an image of a part of the body of the user, an image data analyzer () configured to determine a local hair-growth direction based on data in the image, a controller () configured to generate instructions about a direction in which a hair cutting device () is to be moved in dependence on the determined local hair-growth direction, and a feedback system () configured to provide the instructions to the user.

System and a method for guiding a user during a shaving procedure

A controller comprising a control module configured to: use a non-optical sensor to perform motion detection; in response to the non-optical sensor detecting motion whilst one or more lighting device is operating in a first state whereby the lighting device(s) illuminates an environment according to a first level or emits no light, control the lighting device(s) to operate in a second state whereby the lighting device(s) illuminates the environment according to a second level higher than the first level, use a light sensor to perform motion detection whilst the lighting device(s) is operating in the second state; if no motion is detected by the light sensor, control the lighting device(s) to operate in the first state or a further state; and in response to the light sensor detecting motion, control the lighting device(s) to illuminate the environment according to a third level higher than the second level.

Sensing within a region

A method of self-calibrating a lighting device, comprising: &#x2014;monitoring a calibration area, which encompasses at least a part of an area being illuminable by the lighting device; and&#x2014;calibrating the light output settings of the lighting device. The monitoring operation includes repeating: &#x2014;detecting any relevant change, out of a set of relevant changes comprising at least a light intensity change, in the calibration area during a monitoring time, while keeping the light output of the lighting device constant; and&#x2014;determining an amount of change within the monitoring time; until the amount of change is below a limit value. Thereby the lighting device does not perform the calibration until it has detected a period of no or small changes.
