| Research Abstract |
In this research, we carried out a basic study for a method for preventing from the occurrence of the harmful optical stimulus of which the large-sized high-output digital signage group has a possibility to cause. We firstly produce experimentally the optical wireless communication system which efficiently communicates between displays, and evaluate the bit error rate (BER) performance of this system by the transmission experiment. As a result of data transmission experiment, we clarified that this system can improve the BER performance compared with a conventional system. Then, we considered about indispensable information for avoiding the occurrence of health impairment which is caused by the harmful optical stimulus. Moreover, we designed a management method including the equipment configuration which fits current circumstance of information and communication and a method for evaluating risk of the occurrence of the health impairment.
