For anyone concerned that an era of home working could also become one of remote surveillance, the training video for Teleperformance's in-house webcam security system, called TP Observer, is the stuff of bad dreams. Explained by "Anna", a desk-sitting avatar complete with an artificial voice, the video introduces TP Observer as "a risk-mitigation tool that monitors and tracks real time employee behaviour, and detects any violations to pre-set business rules". Anna explains that this means home workers will have an AI-enabled webcam added to their computers that recognises their face, tags their location and scans for "breaches" of rules at random points during a shift. These include an "unknown person" detected at the desk via the facial recognition software, "missing from desk", "detecting an idle user" and "unauthorised mobile phone usage". Anna says: "Any breach detected by the AI triggers a real-time alert to the supervisor for further actions."
