Google Glass has come and gone in the popular world, but it has specialized uses in some settings. For example, in training medical students how to suture, the student wears Glass and the instructor can see exactly what the student sees and does. The feedback can be much more precise because no one has to “look over the shoulder” of the student doctor. They see what she sees.
The second case in which Glass has been shown to be effective is in workshops to teach student doctors to convey emphathy to patients. To train them to react appropriately in difficult, emotional settings (like telling a patient he has terminal cancer), they practice interacting with an actor-patient. The actor-patient wears Glass to record what the student doctor does from the eyes of the patient. They have found this point of view to be very striking in conveying the skill of the student doctor in expressing the appropriate level of empathy and clarity. It is believed to be much more effective as a learning tool than having video recorded from a standing camera. A study is underway to collect the data to assess this assertion.
