RELATIONSHIP BETWEEN DISCOMFORT GLARE AND ELECTROENCEPHALOGRAPHY DURING WORKING IN FRONT OF A WINDOW

It is important to consider discomfort glare in designing comfortable office environment. Architectural Institute of Japan has set UGR and PGSV as design criteria for glare, but those indicators do not completely reflect the needs lighting environments due differences work behavior. For example, when performing a task that requires concentration, worker may prefer environment increase one's level alertness. From subjective degree awakening during behavior, it considered necessary examine method are more suited actions. Therefore, we focused on relationship between EEG, conducted two experiments with different presentation luminance range. The number subjects was 10 (5 males 5 females) both Experiments 1 2, age were 21-24 Experiment 22-25 2. space simulated windows, assuming an space. experimental factors levels window subject' conditions ("Task" looking at monitor doing calculation work, "No task" view without anything). In Exp. 1, 2000, 8000, 14000, 20000 cd/m2, 5000, 14000 cd/m2. measurement indexes GSV, evaluations.
