The number of currently either occupied or vacant study spaces is automatically evaluated every five minutes at most of our locations by counting the number of devices logged into the network at the WLAN access points and – if available – by the number of occupied ethernet ports in the respective area.

The evaluation method is based on a machine learning algorithm that uses manual counting or estimations by library staff as training data. At some locations the number of network connections cannot be determined automatically for technical reasons, in which case the displayed occupancy rate is based solely on manual count.

If the currently displayed occupancy data is older than 10 minutes, the duration of time passed since the last data collection is shown under "Stand".

Seatfinder does not gather data on individual network-compatible devices but only the total number of devices at the respective location. Therefore it isn’t possible to conclude any information about the location of a device or user by the data collected for Seatfinder.

Arrows indicate the development of occupied study spaces during half an hour prior to the currently displayed occupancy rate.

• A single arrow means that the ratio of occupied study spaces changed by 5-10 percent compared to the total number of study spaces available at the specific location.
• Two arrows show that the ratio of occupied spaces changed by more than 10 percent.

The displayed opening hours apply for today and the next six days.
