Sixth Sense is a wearable technology developed by Pranav Mistry that augments the physical world with digital information. It uses a camera to track colored markers on the user's fingers to interpret gestures, sending the data to a smartphone. The smartphone processes the video and projects information back onto nearby surfaces using a projector, allowing interactions through natural hand gestures. Some applications include viewing maps, taking pictures, and accessing information about physical objects. Future enhancements could eliminate color markers through improved gesture tracking and incorporate the camera and projector directly into a mobile device.

1. THE SIXTH SENSE
TECHNOLOGY

3. INTRODUCTION
 Sixth Sense is a 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.
 Steve Mann is considered as the father of Sixth
Sense Technology who made wearable computer
in 1990.

THE DEVICES WHICH ARE USED
IN SIXTH SENSE TECHNOLOGY
ARE:

6. Camera
 Captures an object in view and tracks the user’s hand gestures
 It sends the data to smart phone
 It acts as a digital eye, connecting you to the world of digital
information

7. Color Markers
 It is at the tip of the user’s fingers .
 Marking the user’s fingers with red, yellow, green, and blue tape helps
the webcam recognize gestures
 The movements and arrangements of these makers are interpreted into
gestures that act as interaction instructions for the projected application
interfaces.

8. MIRROR
MIRROR
The usage of the mirror is
significant as the projector
dangles pointing downwards
from the neck.

9. Smart Phone
 A Web-enabled smart phone in
the user’s pocket processes the
video data
 Other software searches the Web
and interprets the hand gestures

10. Projector
 The projector projects visual information enabling surfaces and physical
objects to be used as interfaces
 The project itself contains a battery inside, with 3 hours of battery life.
 A tiny LED projector displays data sent from the smart phone on any
surface in view–object, wall, or person.

12. APPLICATIONS
Viewing Map Taking Pictures Drawing Application
Making Calls Interacting with physical

Getting Information
•Product information
•Book Information
•Flight Updates

13. ADVANTAGES
 Portable
 Support Multi touch and Multi user interaction
 Cost Effective(300$)
 Data access directly from the machines in real time
 Mind map the idea anywhere
 Open Source Software
 Connectedness between world and information

14. DISADVANTAGES
 Hardware limitations of the devices, that we
currently carry around with us.
 For example many phones will not allow the
external camera feed to be manipulated in real
time.
 Post processing can occur however.

15. CONCLUSION
 Sixth Sense recognizes the objects around us, displaying
information automatically .
 The Sixth Sense prototype implements several applications
that demonstrate the usefulness, viability and flexibility of
the system.
 Allowing us to interact with this information via natural
hand gestures

16. FUTURE ENHANCEMENTS
 To get rid of color markers.
 To incorporate camera and projector inside
mobile computing device.
 To have 3D gesture tracking.
 To make Sixth Sense work as fifth Sense for
disabled person.
