Technology Could Enable Computers To "Read The Minds" Of Users
New techniques under development could allow computers to respond to users' thoughts of frustration or boredom (too much or too little work) by applying functional near-infrared spectroscopy technology, which uses light to monitor brain blood flow as a proxy for user workload stress. Applying this noninvasive, portable imaging technology in new ways, the researchers hope to gain real-time insight into the brain's emotional cues.
except that MIT already showed that under certain conditions foil on the head actually focuses electromagnetic radiation, a very ineffective "brain wave shield" indeed. although this one in particular seems to require a measurement of blood flow, presumably anything that shields against electromagnetic radiation capable of measuring blood flow would be sufficient. :)
Sigs are too short to say anything truly profound so read the above post instead.
They will use the stress level to monitor if you are providing enough output. Obviously, Maximum Stress(tm) = Maximum Output(tm).
This feeds directly into the whip cracking algorithm.
