Method and devices for determining visual attention in multi-location video conferencing

摘要

A method for determining video attention of a to be alerted participant (user 1) of a multi-location video conference taking place between a first plurality of participants comprising said to be alerted participant (user1), said first plurality of participants being distributed over a second plurality of locations (room1, room2, ... , roomn), comprises the steps of
- receiving a signal (U1) from said to be alerted participant (user1)
- transmitting respective video data (video room1, video room2,...,video room n) from said respective locations to a video composing an analysis module (VAD)
- generating by said video composing and analysis module (VAD) respective display video data (video display1, video display 2,...,video display n) from said respective video data (video room1, video room 2, ..., video room n) for being transmitted back and being displayed to and in said respective locations
- performing a first analysis of the respective display video data (video display1, video display 2, ...,video display n) for determining the identity of the respective video participants displayed and for checking whether said to be alerted participant (user 1) forms part of the respective video participants displayed in the respective display video data (video display1, video display 2,...,video display n),
- performing a second analysis of the respective video data (video room1, video room 2, ..., video room n) for determining the activity performed by the first plurality of participants in said respective video locations (room1, room2, ..., roomn),
- combining the results of said first analysis and said second analysis for thereby determining whether said to be alerted participant (user 1) is being watched by at least some other participant in another location, and in case said to be alerted participant is being watched by at least some other participant in another location,
- alerting said to be alerted participant (user 1) via the provisioning of a trigger signal (TU1) to a personal device (MD1) of said to be alerted participant (user 1).
