Yes, it's known as a CAM ( Crew Alertness Monitor ). Basically a system linked into the FMC ( Flight Management Computer ) which continuosly monitors switch action on MCP, EFIS control panel, CDU's and radios to name but a few. After around 15 minutes or so after last switch action was detected, an advisory message 'PILOT RESPONSE' is displayed. If there is still no action approx 5 minutes after this then a caution message is displayed. A further 5 minutes will lead to a warning. In the descent, the timings are reduced to 5,6 and 7 minutes respectively, ie, after 7 minutes in the descent you'll be getting a warning. Pushing ANY monitored swich will cancel the 'PILOT RESPONSE' message. Simple, but it works.
Err...........apart from in this case it would appear!
