Walking and sit to stand are activities carried out by all the people many times during the day, but physical disabilities due to age and diseases create needs of assistive devices to help elderly people during their daily life. This study aims to study the different types and mechanisms of the assistive devices. We will analyze the limitations and the challenges faced by the researchers in this field. We will introduce the Assistive Device developed at the Egypt-Japan University of Science and Technology, named E-JUST Assistive Device (EJAD). EJAD will be a low cost intelligent assistive device to help elders in walking and sit-to-stand activities.

Robots are well established in science and technique. They are used in different environments and they have different structures. Typical robot movements are rapid and steepy when the movement direction changes occurs. It is not necessary to replicate a biological nature based solution for most tasks, so such movements are acceptable and simpler to obtain. Control algorithms are simpler for such cases, development and settings of such controllers are morestraightforward.

Much of the developed world’s construction workforce is increasing in average age, and yet construction workers typically retire well before they reach the age of sixty. One reason is that their bodies are worn out because of the nature of the work. We therefore face the challenge of both reducing their physical stress and increasing their productive work life, if we wish to avert an economic and social crunch given the demographic trends towards an aging population in most developed countries. In particular, recent statistics from the U.S Department of labor show that 6.9% of all Workrelated Musculoskeletal Disorders (WMSDs) among workers in 2008 affected shoulders; this percentage becomes much larger for electricians, carpenters, and related construction crafts. The cost to our industry and to society is huge, and it is unnecessary. Reduction of certain types of movements and improvements in posture can result in reduced rates of shoulder WMSDs and in extended work lives. This can be done with a combination of robotics, work re-design, and work monitoring. This paper provides the statistical background and economic analysis that supports the scope of the problem, presents background on the kinematics of shoulder movement, and explains the biomechanics and causes of shoulder injuries. Then, preliminary results are presented for a prototype of a simple, low-cost, sensing solution for automatically monitoring undesirable movements and patterns of motion. It is expected that this could be broadly implemented to help reduce Construction Work-related Musculoskeletal Disorders (WMSDs).

Virtual Reality (VR) technology enables users to interact with three-dimensional data, providing a potentially powerful interface to both static and dynamic information VR has existed in various forms since its inception. It has been known by names such as synthetic environment, cyberspace, artificial reality, simulator technology and so on and so forth before VR was eventually adopted. Though VR has existed from the late 1960s, its latest manifestation, desktop screen-based semiimmersive type which made its first appearance in entertainment industry, has made it come within the realm of possibility for general creation and use. As a result of proliferation of desktop VR, the technology has continued to develop applications that are less than fully immersive. These non-immersive VR applications are far less expensive and technically daunting and have made inroads into industry training and development.
