A METHOD OF DERIVING A CURRENT USER ACTIVITY FROM A LIGHT SETTING.

摘要

A method 400 of deriving a current user activity from a light setting is disclosed. The method 400 comprises obtaining 402 a set of current parameters, the set of current parameters comprising a current light setting of a lighting device 202, a current location of the lighting device 202 and a current time of day, accessing 404 a memory 102 storing associations between user activities and sets of stored parameters, the sets of stored parameters comprising light settings, locations of one or more lighting devices 202 and times of day, comparing 406 the set of current parameters to the sets of stored parameters, so as to determine if a similarity criterion has been met between a set of stored parameters and the set of current parameters, and determining 408, if the similarity criterion has been met, a user activity associated with the set of stored parameters.
