The aim of this paper is to describe a new Navigation technique to assist the blind and people with low vision to reach their destinations in an indoor environment. The proposed technique is based on our previous positioning technique using active Radio-frequency identification (RFID) technology. A Global Positioning System (GPS) does not work efficiently(More)
—The aim of this paper is to develop a new positioning technique to assist the blind and people with low vision to indicate their locations and reach their destinations. The presented technique is based on a combination of power level and Signal Strength Indicator (SSI) using active Radio Frequency Identification RFID technology. The system uses a mobile(More)
The aim of this paper is to describe a new positioning technique to assist the blind and people with low vision to indicate their location and reach their destinations in both indoor and outdoor environments. The proposed technique is based on a combination of power attenuation and a signal strength indicator (SSI) using active Radio-frequency(More)
E-Government increases transparency and improves communication between the government and the users. However, users' adoption and usage is less than satisfactory in many countries, particularly in developing countries. This is a significant factor that can lead to e-Government failure and, therefore, to the waste of budget and effort. Unlike much research(More)
Providing e-Government services to business sector is a fundamental mission of governmental agencies in Saudi Arabia. The adoption of e-Government systems is less than satisfactory in many countries, particularly in developing countries. One pertinent, unanswered question is what are the key factors that influence the adoption and utilisation level of users(More)
In the development of general system design approaches the main concern is whether the approach meets the proposed system's specifications and the ability of the system to operate for a specified period of time within those specifications. However, with the expansion in the field of sensitive and complex systems, e.g. e-health monitoring systems, a great(More)
In previous papers, we presented a navigational system for use by the blind and people with low vision. The system was built upon two technologies, Radio Frequency Identification (RFID) tags and Quick Response (QR) Codes. The system has been tested by sighted people and it has reached a high level of satisfactory results to identify the current position of(More)
The aim of this paper is to present a service for blind and people with low vision to assist them to cross the street independently. The presented approach provides the user with significant information such as detection of pedestrian crossing signal from any point of view, when the pedestrian crossing signal light is green, the detection of dynamic and(More)
