Sixth Sense Technology Wiki 2016

Published on Feb 15, 2021


Sixth Sense Technology integrates digital information into the physical world and its objects, making the entire world your computer. It can turn any surface into a touch-screen for computing, controlled by simple hand gestures. It is not a technology which is aimed at changing human habits but causing computers and other machines to adapt to human needs.

It also supports multi user and multi touch provisions. Sixth Sense device is a mini-projector coupled with a camera and a cell phone-which acts as the computer and your connection to the Cloud, all the information stored on the web. The current prototype costs around $350. The Sixth Sense prototype is used to implement several applications that have shown the usefulness, viability and flexibility of the system

Introduction of Sixth Sense Technology

'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 the hardware components are coupled in a pendant like mobile wearable device. The Sixth Sense prototype is comprised of a pocket projector, a mirror,colored marker and a camera. The camera, mirror and projector is connected wirelessly to a blue tooth smart phone device that can easily fit into the user's pocket.A software then processes the data that is collected by the capturing device and produces analysis.The software that is used in sixth sense device is open source type

How Sixth Sense Technology Work

Gesture Recognition

It is a technology which is aimed at interpreting human gestures with the help of mathematical algorithms. Gesture recognition technique basically focuses on the emotion recognition from the face and hand gesture recognition. Gender recognition technique enables humans to interact with computers in a more direct way without using any external interfacing devices. It can provide a much better alternative to text user interfaces and graphical user interface which requires the need of a keyboard or mouse to interact with the computer. Interfaces which solely depends on the gestures requires precise hand pose tracking.

In the early versions of gesture recognition process special type of hand gloves which provide information about hand position orientation and flux of the fingers. In the SixthSense devices colored bands are used for this purpose. Once hand pose has been captured the gestures can be recognized using different technique's. Neural network approaches or statistical templates are the commonly used techniques used for the recognition purposes. This technique have an high accuracy usually showing accuracy of more than 95%. Time dependent neural network will also be used for real time recognition of the gestures

Sixth Sense Technology


2.1.1 Portable

One of the main advantages of the sixth sense devices is its small size and portability. It can be easily carried around without any difficulty.The prototype of the sixth sense is deigned in a such a way that it gives more importance to the portability factor. All the devices are light in weight and the smart phone can easily fit into the users pocket.

2.1.2 Support multi touch and multi user interaction

Multi touch and multi user interaction is another added feature of the sixth sense devices. Multi sensing technique allows the user to interact with system with more than one than one finger at a time.. Sixth sense devices also in-cooperates multi user functionality. This is typically useful for large interaction scenarios such as interactive table tops and walls.

2.1.3 Cost effective

The cost incurred for the construction of the sixth sense proto type is quiet low. It was made from parts collected together from common devices. And a typical sixth sense device cost up to $300. The sixth sense devices have not been made in large scale for commercial purpose. Once that happens it’s almost certain that the device will cost much lower than the current price.

2.1.4 Connectedness between real world and digital world

Forming a connection between the real world and the digital world was the main aim of the sixth sense technology.

2.1.5 Data access directly from the machines in real time

With help of a sixth sense device the user can easily access data from any machine at real time speed. The user doesn’t require any machine-human interface to access the data. The data access through recognition of hand gestures is much easier and user friendlier compared to the text user interface or graphical user interface which requires keyboard or mouse.

2.1.6 Mind map the idea anywhere

With the advent of the sixth sense device, requirement of a platform or a screen to analyse and interpret the data has become obsolete. We can project the information into any any surface and can work and manage the data as per our convenience..

2.1.7 Open source software

The software that is used to interpret and analysis the data collected bythe device is made open source. This enables other developers to contribute to the development of the system


The sixth sense technology finds a lot of application in the modern world. The sixth sense devices bridge the gap by bringing the digital world into the real world and in that process allowing the users toiu interact with the information without the help of any machine interfaces. Prototypes of the sixth sense device have demonstrated viability, usefulness and flexibility of this new technology. According to the words of its developers the extend of use of this new device is only limited by the imagination of human beings. Some practical applications of the sixth sense technology is given below

2.2.1 Map Application

With the help of a map application the user can call upon any map of his/her choice and navigate through them by projecting the map on to any surface.By using the thumb and index fingers movements the user can zoom in, zoom out or pan the selected map.

2.2.2 Taking Pictures

Another application of sixth sense devices is the implementation of a gestural camera. This camera takes the photo of the location user is looking at by detecting the framing gesture. After taking the desired number of photos we can project them onto any surfaces and then use gestures to sort through those photos and organize and resize them.

2.2.3 Drawing Application

The drawing application allows the user you to draw on any surface by tracking the fingertip movements of the user’s index finger. The pictures that are drawn by the user can be stored and replaced on any other surface. The user can also shuffle through various pictures and drawing by using the hand gesture movements

2.2.4 Making Calls

We can make calls with help of sixth sense device .The sixth sense device is used to project the keypad into your palm and the using that virtual keypad we can make calls to anyone.

2.2.5 Interacting with physical objects

The SixthSense system also helps to interact with physical objects we use in a better way. It augments physical objects by projecting more information about these objects projected on them. For example, a gesture of drawing a circle on the user’s wrist projects an analog watch on the users hand. Similarly a newspaper can show live video news or dynamic information can be provided on a regular piece of paper

2.2.6 Getting Information

Sixth sense devices can be used for getting various information relating to our everyday life by getting in contact with objects

2.2.7 Product Information:

Sixth sense technology uses marker technology or image recognition techniques to recognize the objects we pick in our hand and then provide information relating to that product.

2.2.8 Book Information:

By holding and shuffling through the book pages, the sixth sense provides Amazon ratings on that book, other reviews and other relevant things related to the book.

2.2.9 Flight Updates:

With the help of the sixth sense technology it is no longer required to log into any sites for checking the status of the flights. The system will recognize your boarding pass and let you know whether the flight is on time or not.

2.2.10 Information About People:

With help of face recognition techniques the sixth sense devices are able to provide information about the people when we meet them. The sensor detects the face and checks the data base for the relevant information.The system will then project the relevant information about a person like what they do, where they work


The sixth sense technology and devices are definitely the way forward. The sixth sense recognizes the objects around us and displays the information relating to those objects in a real time environment. The sixth sense technology allows the user to interact the information through hand gestures. This is a quiet efficient way compared to the text and graphic based user interface. It has the potential to form the transparent user interface for accessing the information around us. . Even though the sixth sense devices are currently in development stages and have not been used in large now, it’s quiet predictable that this technology have the potential to revolutionise the way in which we interacts with the digital world. As Mr PranavMistry says “imagination of the human brain is the only thing that could limit the application of the sixth sense technology.
