• Resumen

  • Hodson talks about a device that can tell when one is bored or overworked. The system monitors the workload by pulsing light into his prefrontal cortex 12 times a second. The amount of light that oxygenated and deoxygenated hemoglobin in the blood there absorbs and reflects gives an indication of how mentally engaged a person. Harder brain work calls for more oxygenated blood, and changes how the light is absorbed. Software interprets the signal from this functional near infrared spectroscopy (fNIRS) and uses it to assign him the right level of work. Dan Afergan, who is running the study at Tufts University in Medford, Massachusetts, points to an on-screen readout.
