Abstract
Methods and systems are provided for a transportation vehicle. One method includes computing an average of light sensor data of a first group of seat devices; comparing the computed average with a previous average of the first group and at least a second group; determining that the computed average of the light sensor data of the first group is different from the previous average by a threshold value; identifying a change in an ambient light condition based on a difference between the computed average and the previous average of the light sensor data of the first group and comparison of the computed average with the average of the light sensor data of the second group; and automatically adjusting a brightness level of the seat devices of the first group, in response to the change in the ambient light condition.
