Timeline is the main user interface for Google Glass. It allows the use of Glass through static and live cards, voice commands and to launch other glassware. The Timeline is a scrollable interface with past, present and future cards.
The Timeline is organized into the following sections:
Settings <- Present/Future Cards <- HOME -> Past Cards
1. Home Screen
This is the default card and has a digital clock at its center. It provides access to all the functionality of Glass through various touch and voice commands. This card gives access to all the immersion type glassware by saying the “ok glass” command. We can also access these cards by touch controls.

The following describes the types of cards and other options.
Live Cards
These cards provide real time content and are always shown on the left of the home screen. Live cards update frequently and show custom graphics for user interaction. Live cards have access to low-level hardware sensors like GPS, accelerometer, gyroscope and so on. Live cards are started from the Home Screen and always must contain a menu option to stop/remove the card.

Static Cards
These cards mostly show static content like text, images and videos. Generally these cards are on the right of the home screen but some cards with a future timestamp are shown on the left.

Immersions
Immersions are separate apps that run outside the main Glass timeline. It takes control of the Glass momentarily and the user can return to the Glass by swiping down. They can be started from the Glass menu or a static card.
