System and method for controlling environmental physical properties, computer program product, color and intensity adjustable lamp and electronic device

摘要

A system (100) and a method for controlling an environmental physical characteristic in an environment of a person (105), a color and intensity tunable lamp, an electronic device and a computer program product are provided. The system (100) comprises an environment influencing means (102), a sensor (104), an input means (134) and a controller (130). The environment influencing means (102) changes the environmental physical characteristic in response to a control signal (112) indicating a desired influencing of the environmental physical characteristic. The sensor (104) obtains a sensor signal (122) representing a physiological condition of the person (105). The input means (134) obtains a user setting signal (132) representing a user setting with respect to the environmental physical characteristic. The controller (130) receives the sensor signal (122) and the user setting signal (132) and generates the control signal (112) by applying an original function (114) to the sensor signal (122). The controller (130) defines an adapted function in response to receiving the user setting signal (132), wherein the adapted function provides the control signal(112) which, if applied to the sensor signal (122) occurring when the user setting signal(132) was received, causes the environmental physical characteristic to become closer to the user setting than when the original function (114) is applied to the sensor signal occurring when the user setting signal (132) was received. The controller (130) subsequently applies the adapted function. Finally, the controller (130) gradually changes the applied adapted function towards another function.
