Integration of information
Providing “just-in-time” information
What is Sixth Sense?
Wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information
INTRODUCTION
Augmented Reality.
Wearable GesturalInterface.
Converts intangible,digital information out into tangible world.
Interaction with the projected information.
No need of special glasses.
The Device……..
Overview of Sixth Sense Device
Integration of information
Gestural interface
Augmentation of information
Wearable interface
Technologies implemented
Augmented Reality
Object Augmentation
Computer vision based techniques
Augmented reality (AR)
Term for a live direct or indirect view of a physical real-world environment whose elements are merged with virtual, computer generated images, creating a mixed reality
Object augmentation
the camera recognizes and tracks physical objects such as a newspaper, a coffee cup, or a book and the projector projects relevant visual information on them.
Computer-vision techniques
track objects and align projected visual information by matching pre-printed static color markers (or patterns) on these objects with the markers projected by the projector.
Components
Camera
Projector
Mobile Phone
Coloured markers
How does the device work?
Camera-logitech quick cam
recognizes and tracks user’s handgestures and physical objects using computer vision based techniques
Projector-3MM Pro110
projects visual information enabling surfaces walls and physical objects around us to be used as interfaces
Mobile phone
projector and camera are connected to the mobile computing device in the user’s pocket
Coloured markers
visual tracking fiducials
Software Requirements
Microsoft Windows platform using C#,WPF and openCV
Internet Connection
Benefits of having a network
Access to the Internet.
Communication.
Wireless network connection used:- reduces additional burden of wiring
Gestural interaction
3 types of gestures
Supported by multitouch systems
Free hand gestures
