  • Patent number: 10342475
    Abstract: In a threshold estimation apparatus, a setting unit sets an initial intensity value for each electrode. A selection unit randomly selects an electrode. A stimulation unit, via the selected electrode, stimulates a living subject at an intensity set for the electrode. A detection unit detects the presence or absence of a response evoked by the stimulation. An update unit reduces or increases the intensity associated with the selected electrode, based on the presence or absence of the response evoked by the stimulation. An estimation unit, if the thus updated intensity associated with each electrode satisfies a convergence condition, estimates a convergence value as a threshold associated with the electrode. The threshold estimation apparatus repeats these processes until thresholds associated with all electrodes are estimated. If the same electrode was consecutively selected, the time interval between a stimulation and a subsequent stimulation is adjusted.

    Abstract: A system and method for improving student learning includes learning material that is presented to a student and a device that is used to acquire physiological data from the student in real time during a learning session. A cognitive assessment algorithm determines a cognitive state of the student using the physiological data, and a learning action algorithm modifies the presentation of the learning material in response to the student's cognitive state. The learning material can include lectures, questions asked of the student or problems or activities being completed by the student. In one embodiment, the device directly measures the brain activity of the student to determine the student's cognitive state. The cognitive state of the student can include the student's cognitive load, engagement or fatigue.
