It's standard practice to auto-minimize / lock electronic health records (EHRs) after a few minutes of inactivity. It's a reasonable practice: people forget to lock the computer when they walk away, so the computer needs to auto-lock to prevent unauthorized access. Unfortunately, this practice is extremely frustrating for users. Logging in and unlocking the EHR 20 or 30 times daily is extremely annoying. I've spoken with dozens of doctors who enter 3 sets of usernames and passwords to access their hospital EHR. Just imagine going through 3 sets of usernames and passwords dozens of times daily. It's quite aggravating.

Google Glass and other eyeware computers have sensors that can detect when the user takes the glasses on and off. This is a powerful concept. It means that users only need to authenticate and login once per wear instead of once every ten minutes. Eyeware computers, by virtue of the inherent advantages of the form factor, can perform certain tasks in 10 seconds that take 30-45 seconds on traditional form factors. Let's walk through a simple scenario - looking up the patient's blood pressure - to see how the substantial time saving is possible:

Laptop: wake laptop from sleep, login to Windows, login into Citrix (optional depending on the hospital), login to EHR, find patient, find blood pressure.

Smartphone/tablet: wake from sleep, login into Windows/iOs, login to EHR, find patient, find blood pressure.

Glass: nod head to wake Glass from sleep, ask "Ok Glass, what's Mr. Smith's blood pressure?"

Glass doesn't replace traditional EHR form factors such as laptops, tablets, and desktops. It simply doesn't have the screen real estate to act as a complete form factor replacement. But as a complementary form factor, Glass excels at streamlining brief EHR interactions that are cumbersome in traditional form factors.
