Lifelong learning means there is a need to test knowledge of people all the time to measure progress. The time it takes to develop tests, administer them and grade them takes a huge budget from the already tight education budget.
What if we could make a simple device that would use biometrics to authenticate a person and then flash images and concepts from the study materials in front of his or her eyes. A low cost EEG could measure the brain wave activity in response to each image and thus gauge the familiarity of this concepts to the student.
This is of course not accurate but could still give an indication of the level of familiarity of the person with the concepts. This can allow to test and grade people automatically, fast and with very low cost and eliminate cheating.
Could probably be used for knowledge testing rather than reasoning testing.
