Abstract
A method for alerting difference in user sentiment of a user using a door. The method is performed in a user analysis device. The method comprises: receiving sensor data from at least two sensors of different sensor types, the sensor data comprising data relating to a user in the vicinity of a door; determining, based on the sensor data, a first user sentiment prior to using the door; determining, based on the sensor data, a second user sentiment after using the door; deriving a difference in user sentiment between the first user sentiment and the second user sentiment; detecting that the difference in user sentiment is greater than a threshold; and generating an alert signal, indicating that the difference in user sentiment is greater than the threshold.
