A SYSTEM AND A METHOD FOR CONTROLLING AN ENVIRONMENTAL PHYSICAL CHARACTERISTIC, A COMPUTER PROGRAM PRODUCT, A COLOR AND INTENSITY TUNABLE LAMP AND AN ELECTRONIC DEVICE
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.인간(105)의 환경에서 환경의 물리적 특징을 제어하기 위한 시스템(100)과 방법, 색과 강도를 조정할 수 있는 램프, 전자 장치 그리고 컴퓨터 프로그램 제품이 제공된다. 시스템(100)은 환경 영향 수단(102), 센서(104), 입력 수단(134) 그리고 제어기(130)를 포함한다. 환경 영향 수단(102)은 환경의 물리적 특징의 바라는 영향을 나타내는 제어 신호(112)에 응답하여, 환경의 물리적 특징을 변화시킨다. 센서(104)는 인간(105)의 생리적 조건을 나타내는 센서 신호(122)를 획득한다. 입력 수단(134)은 환경의 물리적 특징에 대한 사용자 설정을 나타내는 사용자 설정 신호(13
