Always-on voice commands, wink-based photography
Google Glass has a number of hidden features not normally available to users, giving a hint for what is in store for future iterations of the onboard software. Hidden inside the firmware of the Explorer Edition headset are a number of "Labs" items that were left behind by Google in the device, including options to keep the "Ok Glass" voice command function always listening, and the ability to launch a browser.
A flag titled "Web-Browsing," found by Android Police, seemingly allows a search result to be tapped upon, which in turn brings up the option to "View Website." This will in theory load up a web browser, but since Glass does not have one built it, a side-loaded installation of Chrome can be opened, though the Glass UI continues to jump in front of the browser.
A further option for a "Touch Voice Menu" brings up an alternative version of the main OK Glass menu. When used normally, the menu allows the wearer to scroll up and down the list of tasks, such as "Take a Picture" and "Record a Video," with the extra version presenting the list items on individual cards, forcing large swipes that are inefficient compared to the default view.
Other items found in the Labs section in various states of functionality include video stabilization, wink photography, a QR code reader, third-party voice functions, and the option to switch servers the Glass unit connects to.
