AI summary

A display system includes an acquirer, an estimator, and a controller. The acquirer acquires a first detection value and a second detection value from a temperature sensor and a humidity sensor, respectively. The temperature sensor and the humidity sensor are both included in a ventilator that ventilates a room. The estimator estimates, based on the first detection value and the second detection value that are acquired by the acquirer, an apparent temperature distribution representing a distribution of apparent temperatures in a height direction in the room. The controller makes a display device present the apparent temperature distribution estimated by the estimator.
