9. MIRROR API: THE MAJOR FEATURE

10. TIMELINE AND CARDS
• Timeline cards display content from various Glassware.
• You can insert, update, read, and delete timeline
cards, attach objects to a timeline card, such as a
location or media.
• Timeline cards can be text, rich HTML, images, or
video.

11. INSERTING A TIMELINE CARD
POST /mirror/v1/timeline HTTP/1.1
Host: www.googleapis.com
Authorization: Bearer {auth token}
Content-Type: application/json
Content-Length: 26
{ "text": "Hello world" }
JSON

13. CONTACTS
CODE
POST /mirror/v1/contacts HTTP/1.1
Authorization: Bearer {auth token}
Content-Type: application/json
Content-Length: {length}
{
"id": “J_Murphy"
"displayName": “Jenny Murphy",
"iconUrl":
"https://developers.google.com/glass/images/harold.jpg"
"priority": 7
}
JSON

14. LOCATIONS
CODE
public static void printLatestLocation(Mirror service)
{
Location location =service.locations().get(“latest”).execute();
System.out.println(“Location recorded on: “+ location.getTimestamp());
System.out.println(“> Lat: “+ location.getLatitude());
System.out.println(“>Long: “+ location.getLongitude());
System.out.println(“>Accuracy:”+ location.getAccuracy() + “meters”);
}
JAVA

15. DESIGN PRINCIPLES
AS STATED BY, Timothy Jordon, Senior Developer, Google.
• Design for Glass. and it’s unique interface.
• Don’t get in the way. no intermodal dialogs.
• Keep it timely. Glass is “Right Now” Device.
• Avoid the Unexpected. Don’t surprise the users.

16. DESIGN PRINCIPLES
APP LIMITATIONS:
•No charging for apps.
•No ads.
•No face recognition.
•No App data to be stored on the User Device.

17. BENEFITS
• Benefits Education.
• Live Information When You Need It.
• Health Monitor interface.
• Assisting Busy Lives.
• Documentaries In First Person View.
• Video Conferencing Alternative.
• Works Together With Any Smartphone & Its Apps.

18. DISADVANTAGES
• Recording and privacy issues break a few
codes of ethics.
• As of right now the cost of Google glasses
ranges from $1,500- $3,000 and Available in
USA only.
• Battery life needs to be drastically extended.
• You still need your phone.
• Glass might give you a ‘nerdy’ look.

19. CONCLUSION and FUTURE SCOPE
• Augmented Reality to next level.
• Partnerships with sunglass retailers such as Ray-
Ban and Crizal to provide prescription glasses.
• Will provide Developers more opportunities to
design User Oriented Applications.
• Far more lighter version in future.
• Will be shipping to public @ Rs. 15000/-
