Abstract: According to an aspect, an illumination system includes a plurality of illumination devices each having a light adjustment function. Each of the illumination devices has a first mode in which all of the illumination devices are not subject to light adjustment control, and a second mode in which another illumination device of the illumination devices is subject to the light adjustment control. In the second mode, the illumination device is controlled to be in a light adjustment state different from a light adjustment state in the first mode.

Abstract: A detection device provided with a diffusion degree adjustment region of an illumination device in a detection region where a plurality of detection elements are provided, and a processing device configured to control a diffusion degree change amount of the illumination device in accordance with a movement amount of a touch detection position in the diffusion degree adjustment region are provided. The processing device calculates the diffusion degree change amount corresponding to a first directional component of the movement amount of the touch detection position in the diffusion degree adjustment region, and calculates the diffusion degree change amount corresponding to a second directional component of the movement amount of the touch detection position in the diffusion degree adjustment region, the second directional component being different from the first directional component.

Abstract: According to an aspect, a sensor system includes: a first device including a first controller and a first communicator; and a plurality of second devices each including an altitude sensor, a blood oxygen saturation level sensor, a second controller, and a second communicator. The second controller of the second device is configured to transmit altitude information measured by the altitude sensor and biometric information measured by the blood oxygen saturation level sensor to the first device through the second communicator. The first device has determination information comprising determination thresholds for a blood oxygen saturation level corresponding to different altitudes. The first controller is configured to warn that the blood oxygen saturation level is lower than the determination threshold corresponding to the altitude information based on the altitude information and the biometric information received from each of the second devices through the first communicator and the determination information.
