The system would allow managers to monitor employees' performance by measuring their heart rate, body temperature, movement, facial expression and blood pressure.

To be precise on the patent.."This particular patent application, in general, describes an innovation aimed at improving activity-monitoring systems and uses the monitoring of user heart rate as an example of the kind of physical state that could be monitored to detect when users need assistance with their activities, and to offer assistance by putting them in touch with other users who may be able to help" said Horacio Gutierrez, Microsoft's vice president of intellectual property and licensing.
