Figure 1. Head support (Retrieved from Guidelines for Use of Secondary Postural Support Devices by Wheelchair Users During Travel in Motor Vehicles, 2006) Anterior head support TransSPOT(2010) writes that the anterior head support is not a recommended postural support device of wheelchair users for transportation use because of the occupants may suffer from a neck hyperextension injury in a frontal car crash. If one is necessary to use this device or any form of forehead strap during transportation, Rehabilitation Engineering Research Center on Wheelchair Transportation Safety(2006) recommends that: It should be automatically release but at the lowest force exerted during a crash and still able to maintain effective head support purpose A soft neck collar that is independent of the wheelchair can be applied concurrently but not obstructing the airway like tracheostomy. Beware the forehead strap from slipping downward and tying to the user’s neck Figure 2. Anterior head support (Retrieved from
GUI of the android application have the facility to control the direction of the wheelchair and it has the provision to control electrical home appliances using radio frequency concept. System design uses IOIO board which contains a single MCU that acts as a USB host and interprets commands from an android application. Pin 31 and pin 33 of IOIO board are used as PWM output which is given to DC motor driver MD30C and pin 32 and pin 34 are used as direction control pins. Output of the DC drive is fed to two DC drive to move the wheelchair in different direction. For forward movement of the wheelchair both DC motor are rotated in forward direction.
Eye tracking has been applied to fields that include human factors, cognitive psychology, marketing, and the broad field of human–computer interaction. Especially for people with severe motor disabilities, gaze may be their only means of communicating or controlling their environment [a]. This chapter provides a brief summary of the previous research in this domain and a general idea of what eye tracking systems are. We will first have a quick glance into the history and applications of eye tracking, followed by a brief introduction to currently available eye tracking assistive devices, and close by introducing some common terms that repeatedly appear throughout this report. 1.2.
CAPTER-1 INTRODUCTION 1.1 Overview A wheelchair is a chair fitted with wheels. The device comes in variations allowing either manual propulsion by the seated occupant turning the rear wheels by hand, or electric propulsion by motors. There are often handles behind the seats to allow it to be pushed by another person. Wheelchairs are used by people for whom walking is difficult or impossible due to illness, injury, or disability. People who have difficult sitting and walking often make use of a wheel bench.
Some examples of devices that make use of assistive technology include newly developed computer programs, traffic signals and electric wheelchairs. At the same time, the concept of accessibility also involves the application of adaptive technology which refers to the modification of already existing devices to enable various categories of people such as the disabled to use them in everyday life. For instance, any modifications made to a wheelchair or listening device such as a wheelchair would fall in the realm of adaptive technology. Global
1. INTRODUCTION 1.1 Background A report by World Health Organization (WHO) and International Agency for Prevention of Blindness (IAPB)  stated that there are approximately 285 million persons around the world who are visually impaired, out of which 39 million are completely blind. Africa and other developing countries represent 90% of this statistics. Egypt specifically has one million blind, out of which 14% are children. According to WHO and IAPB, the number of blind people will increase worldwide to reach the double by 2020.
Algorithm can detect: 1) Colors of the clothes; 2) whether the clothes have pattern or have homogeneous color; 3) whether the colours match for a pair of images. Here, I introduce a prototype to help visually impaired people to recognize clothing patterns and colors. The system contains three major components: (1)existing images having different clothing patterns, (2)clothing pattern recognition and color identification by using a computer which can be a desktop, (3)Audio outputs or a text message to provide recognition results of clothing patterns and colors. The image pair is captured by a camera which is connected to a computer. The system focus on these kind of fields where such as pattern
ABSTRACT—Doing exercises is important for health. However, it is often hard for people to motivate themselves to do the recommended amount of exercise. Virtual reality exergames have the potential to overcome this aspect by letting the people forget about the actual exercise. This is done by giving the player an immersive virtual reality experience with an interactive virtual interface and three different difficulty levels of interaction. KEYWORDS—Virtual reality, room-scale, interface design, HTC Vive, Oculus Rift, exergame, health I.
Gaze tracking finds application in medical research and for police work purpose. Recent application of Eye tracking involves the scrolling impact like after we move our eye up or down consequently it will scroll up or down. 2. Literature Review  Vision Base Eye Gaze Tracking For Human Computer
HUMAN COMPUTER INTERFACE – A PORTABLE WIRELESS DEVICE FOR THE DISABLED Abstract Human-Computer Interface (HCI) is an important area of research and development for the disabled. A portable wireless Human-Computer Interface which can be used for the disabled, having motor paralysis or who cannot use their hands in multiple applications is described. A new mouse is proposed as an input device for computers/laptops. The operation of this mouse is based on measurements of rotations of the user’s head and detection of eye blinks Horizontal and vertical movement signals are measured using an accelerometer placed on a cap/helmet .The eye blink detector setup is placed about 1cm above the right eyebrow and 2cm below the lower lid of the right eye
