Back in September of last year, Google released XE9 which brought various features for Explorers. One of these features was the arrival of Vignettes. Vignettes superimpose a screenshot of your Glass display over a picture taken through Glass.
Many Explorers thought of doing this with video of the display on Glass, though this only recently became possible. The ability to record you screen using ADB came natively in Android 4.4 KitKat and now that Glass runs KitKat, we can easily record Glass’ display.
How to record your Google Glass display
- Put on Google Glass and swipe all the way to the left and click on the Settings bundle. Next, navigate to the right and click on the Device Info card. Swipe to right and you will want to tap the “Turn on debug” card, giving our computer access to Glass once plugged in.
- Next, plug Glass into your Mac/Windows computer using the Micro-USB cable provided by Google. I highly recommend using the cable provided by Google because Explorers using third-party cables have run into problems in some cases where their computer won’t recognize Glass.
- For Mac, open Terminal. You can find this basic command prompt app in “Utilities” in your Application folder, or by typing “Terminal” in spotlight. For Windows open CMD. You can open this by clicking the start button, and in the “search programs and files” box, simply type in “CMD”.
I will be using a Mac; however, it is the same process on a Windows machine. Once you have a command prompt window open, type the following and press enter:
You should see something similar to the screenshot below.
4. Type the following; you can name the video anything you like. For this example, we will be using “demo” as our title. Press enter.
adb shell screenrecord /sdcard/demo.mp4
5. To stop the recording, press Ctrl-C.
6. To retrieve the newly recorded video type the following and replace “demo” with the title you inserted above.
adb pull /sdcard/demo.mp4
If you see the following then you successfully recorded your Google Glass display.
7. You will find your video in the Home folder of your computer.
That’s it! You successfully recorded your Google Glass display and now you can use it as a demonstration tool, or however you please.
