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, a predicted mean vote distribution representing a distribution of predicted mean votes in a height direction in the room. The controller makes a display device present the predicted mean vote distribution estimated by the estimator.

An electronic device may include: a first temperature sensor configured to measure a first temperature of body skin; a second temperature sensor configured to measure a second temperature at a position spaced apart from the body skin; and a processor configured to estimate skin heat loss based on the first temperature and the second temperature, and to determine a target ambient temperature for controlling an ambient temperature based on the first temperature and the skin heat loss.
