Go Live with Screencasting on Google Glass

Your Google Glass can use your smartphone to show people a live view of what you’re seeing on the Glass screen. You can show people what you’re looking at on your smartphone, for example, or you can connect Glass to a large monitor or even a projector by connecting the smartphone to the monitor or projector (via an HDMI adapter cable).

Before you can screencast, you need to set up the MyGlass app on your smartphone.

Here are some important screencasting facts to keep in mind:

  • Screencasting doesn’t transfer sound to your phone; the sounds you hear on your Glass stay confined to the Glass speaker. If you’re presenting Glass to an audience, make sure that you tell them what you’re hearing on your Glass as you perform tasks.

  • When you begin your presentation, tell your audience that there’ll be a brief delay before what you see on the Glass screen appears on the smartphone, monitor, or projector. This disclaimer helps your audience members understand that the slow performance they see on the phone, monitor, or projector doesn’t match what they’d see on the Glass screen.

Starting and stopping a screencast

When you’ve set up MyGlass, you can screencast by following these steps:

  1. Open the MyGlass app on your smartphone.

  2. Choose Screencast from the menu.

    The screencast begins immediately, and the phone’s screen displays exactly what you’re seeing on the Glass screen.

  3. To end the screencast, tap the smartphone’s Back or Home button.


Connecting to a video device

HDMI cables allow you to connect your Android smartphone to any video device that has an HDMI port, including most monitors and projectors produced in the past two or three years.

Because each phone is different, be sure to consult your smartphone’s documentation and the manufacturer’s website to find out how to connect your smartphone to your monitor or projector effectively.

Controlling a screencast

If you’re using a smartphone running Android 4.1 or later, you can use the MyGlass smartphone app to control your Glass. (Remote control of your Glass isn’t available in the iOS MyGlass app as of this writing.)

You may want to control your Glass remotely for several reasons:

  • You feel more comfortable using your smartphone to do things on your Glass.

  • You want to transition to the Glass user interface slowly.

  • You want to use your smartphone to show someone else how to navigate the Glass screens while you’re using Glass.

After you begin a screencast, the smartphone screen displays what’s on the Glass screen.


You can use the following gestures on your phone as equivalent gestures on your Glass:

  • Swipe up and down on the smartphone screen to swipe up and down, respectively, on the Glass touchpad.

  • Swipe left and right to swipe backward and forward, respectively, on the Glass touchpad.

  • Tap the smartphone screen to tap the Glass touchpad.

If you decide that you don’t want to use your smartphone to control Glass any longer, just tap your smartphone’s Back or Home button.
