Popis:	The objectives of this empirical study were to contribute to the development of an intelligent, adaptive home lighting system for the elderly. The basic idea was that a carefully chosen dynamic lighting with seemingly ever-increasing ("up") - or ever-decreasing ("down") - illuminance can be used to increase (or decrease) the users' activation level as they wish, a change that will be reflected in objective psychophysiological parameters, in objective performance, and also in subjective feelings. The paper examines the effects of two particular different forms of dynamic lighting --- having the same average illuminance over time --- on the performance of the number verification task (NVT) by older adults. As a group, the older adults showed no difference between the two forms of dynamic lighting. However, by involving the individual's sensation seeking needs it was shown that the kind of dynamism influences both the subjective preferences and the objective visual performance. These findings emphasize the importance and sensitivity of individual characteristics of the elderly and have to be taken into consideration for the design of adaptive lighting systems.
