Abstract: Among other things, we describe monitoring and interactively supervising user activity on a plurality of networked computing devices. Some embodiments relate to methods and systems configured for remote automatic selection and monitoring of a most actively used computer device from among a plurality of computer devices accessible to and logged into by a specific user. Such methods and systems may also involve the display of the user's screen on a dedicated monitoring display device. Where multiple users are monitored, the displays of the user devices that are most actively used may be reproduced on the monitoring device display in dedicated view ports for the users being monitored. Embodiments may involve the use of software agents installed and executing on each user device that is turned on. Such software agents assist in allowing the monitoring device to determine which of the user devices is most actively used by a particular user.
