The EyeRing is a finger-worn device that allows users to access digital information about objects using pointing gestures or touch. It consists of a camera, processor, Bluetooth module, battery, and button attached to a plastic ring. When the button is pressed, the camera takes a snapshot that is sent to a mobile phone via Bluetooth. Computer vision and speech processing on the phone then analyze the image and read out information to the user through a headset. The EyeRing was invented to help both visually impaired and sighted people access information about their environment through an intuitive pointing interaction.

3. INTRODUCTION
Eyering is the finger-worn device that allows using a pointing
gesture or touching to access digital information about objects
and the world which is autonomous, wireless, and include a
single button to initiate the interaction.
Earlier explorations are divided into a few subspaces according
to how they are operated :
• Touching
• Clicking on the device /Pressing

4. HISTORY
World Health Organization (WHO) in 2011, there were about 60
million visually impaired people living in USA and Europe.
EyeRing technology is invented by Roy Shilkrot and another
person Suranga Nanayakkara . who received his PhD in 2010
and BEng in 2005 from National University of Singapore (NUS).

5. FINGER WORN DEVICE
The EyeRing a finger -worn device consist of JPEG Camera, AVR
processor, Bluetooth module, Polymer Lithium-ion battery, and
push button switch. These components are attaches onto ring-
shaped Plastic piece.
Technology is based on extraction of information from images
or vedios .

6. COMPONENTS
• The devices which are used in EyeRing technology are:
• Microcontroller
• Image acquisition module
• Wireless module
Image acquisition module:
Image acquisition model in which they use the C329 UART
JPEG compression module acts as a video camera . User can give
the snapshot command to capture full image with the help of
OV7725 VGA CMOS sensor and the OV529 JPEG engine.

7. • Wireless module: Bluetooth is wireless technology standardized
as IEEE 802.15.1 .The wireless communication between EyeRing
and mobile device is done through a Roving Networks RN42
Bluetooth module is low power.

9. WORKING :
• Speech processing engine and computer vision engine were
implemented on a mobile phone.
• User would single click the pushbutton switch on the side of the
ring using his thumb.
• A snapshot is taken from the camera and the image is
transferred via Bluetooth to the mobile phone.
• Mobile phone then analyzes the image using our computer
vision engine.
• Then the Android application uses a Text-to- Speech module to
read out the information though a headset.

10. APPLICATION :
• Currency Detector
• Colour Detector
• Reading non- braille

11. CONCLUSION :
• EyeRing suggests a novel interaction method for both visually
impaired and sighted people. We choose to base the interaction
on a human gesture that is ubiquitous in any language and
culture – pointing with the index finger. This has determined
the nature and design of the ring apparatus, location of the
camera and trigger. Preliminary feedback received from a
visually impaired user supports that EyeRing assistive
applications are intuitive and seamless.
