As Digital Still Cameras (DSC) become smaller, cheaper and higher in resolution, photographs are increasingly prone to blurring from shaky hands. Optical image stabilization (OIS) is an effective solution that addresses the quality of images, and is an idea that has been around for at least 30 years. It has only recently made its way into the low-cost consumer camera market, and will soon be migrating to the higher end camera phones. This paper provides an overview of common design practices and considerations for optical image stabilization and how silicon-based MEMS dual-axis gyroscopes with their size, cost and performance advantages are enabling this vital function for image capturing devices

This device is very useful for the people who surfering with eye blindness and this can able to detect the obstacles with the help of ultrasonic sensor.
In this technology, light is passed through transmission channel as it is the fastest medium. It overcomes the defect of WI-FI as well. Transmission of data takes place through illumination. Using this, we can connect to several devices under a single LED light.
Wi-Vi or wireless vision is one of the most modern technologies which use wireless fidelity or Wi-Fi as the core principle. Basically, it deals with tracking and manipulation of Wi-Fi signals.
Wi-Vi is used to image the obstacles or solids behind any wall or obstructions. The most important advantage of this is it is completely wireless and no cables or wires are used. Hence it becomes more suitable for usage in mobile devices and other lightweight technologies. Wireless facility also allows it to use in armed force and other security agencies.
As we know that SOANR and RADAR uses the principle of transmission and reflected waves, the Wi-Vi which uses the same principle can be called as an adaptation of those. But it also posses several differences and simpler apparatus. We will see those modifications on the coming pages of the paper.

Microcontroller Based Obstacle Detection Device Using Voice Signal for the V...IJMER
This paper aims in helping the visually impaired people through an electronic aid, which
senses any obstacle in the path and alarms the user of the obstacle. The device uses a simple principle of
transmitting an ultrasonic signal in the path generated by a wave generator. The signal gets reflected by
the obstacle (if any) in the path. The reflected signal is sensed by a sensor and produces a sound signal in
the form of voice. This voice signal directs the visually impaired person to identify the obstacles in front
of them

Design and Development of Secure Navigation System for Visually Impaired Peopleijcsit
The proposed work presents a navigation system, which detects the obstacles and also guide to visually impaired people about appropriate path. The system we propose detects the obstacle via an infrared based detecting system and sends back vibro-tactile or sound (buzzer) feedback to inform the user about its position. The most common method of obstacle detection, used by blind people is the walking stick. The limitation of walking stick is that, it does not provide protection near to head area. A sensor module is fixed on a light weight cap allowing the user to obtain the information about obstacles (near to head area) and also about correct path on which the user should move. When the user uses this system with cane, he is fully protected about obstacles and can navigate freely into the environment.
Smart Cane for Blind Person Assisted with Android Application and Save Our So...Dr. Amarjeet Singh
Today technology is improving daily in different
aspects in order to provide flexible proposes Smart Cane

system to navigate a blind person and help in emergency
situation. In this paper, user friendly device is proposed that
can identify the obstacles in the path using ultrasonic sensors.
In this system blind person will navigated through a cane
interfaced with an android application. A blind person can
establish voice call or SMS to a predefined number just by
pressing the emergency button on cane using GSM module. In
addition, people will get notified as Facebook status updated
with emergency alert. This system develop an android
application which is smart and user-friendly. While walking
in public place during night time, the blind person can use
cane as a flashlight which illuminates automatically.
New development in sensors, radar and ultrasonic technologies has proved to be a boon for electronics
travelling aids (ETAs). These devices are widely used by blind and physically challenged peoples. C5 laser
cane, Mowat sensor, belt and binaural sonic aid, NAV guide cane are among popular electronic travelling
aids used by blind peoples. For physically challenged person electric wheel chairs controlled by joystick,
eye movement and voice recognition are also available but they have their own limitation in terms of
operating complexity, noise environment and cost. Our paper proposes an automated innovative
wheelchair controlled by neck position of person. It uses simple LEDs, photo sensor, motor and
microcontroller to control the movement of wheelchair
Sensor Stick walking aid for the blindsIJRES Journal
In this paper, few methods of aiding and guiding visually impaired persons are presented. They are analyzed and studied thoroughly. Some commercially available systems help in aiding people with disabilities of seeing and give information refereeing to the location of the users. We propose an intelligent” stick equipped with an ultrasonic sensor that takes information about the environment. This information is processed and is delivered to the handle stick and thus can be interpreted by the users. The stick will produce beeping sound with varying speed according to the distances of obstacles. This stick will provide assists to visually impaired persons by providing informations related to obstacles distances. This device was tested with blind persons and results are presented.
