Abstract:
Light has a real important impact on our life, determining the circadian rhythm, the rhythm of our daily activity. Light is beneficial for healthy people, but it can be also very helpful for treating disease or for enhancing the comfort and well being. In the frame of our European project, ALADIN, light is in-tended to be a support for the elderly, in order to enhance their daily performance. The performance is appreciated by activity specific values of psycho-physiological parameters that can be modified by light. In this paper it will be described the light controller, that part of the system which realizes the adaptation of light after this parameters in order to obtain an improvement of “activation” or “relaxation” status for a certain person. The light controller is realized in two variants: one based upon the Monte Carlo algorithm, and the second that uses on the Simulated Annealing algorithm. Some experimental results are presented.
Acknowledgement:
This study was done inside the Military framework, for the “ALADIN - Ambient Lighting Assistance for an Ageing Population” project. We would like to thank to our partners from Command and Staff Faculty, Department of Armaments - Ministry of National Defense and also to our partners from Agency for Military Information Systems and Services for their help in implementing our software application.
