Wheelchair travelers argued that a companion was required for an enjoyable holiday that could meet their needs. In addition, the results revealed that the types of wheelchairs used by disabled passengers differ. The disabled stated that the wheelchairs they use in daily life are not suitable for use on the beach, sand or water. Despite the economic, social and technological change opportunities, basic tourism service expectations of PWDS are not met. This research project is a comprehensive study that makes determinations in terms of examining the social status of disabled people in terms of social sciences, examining the place and importance of disabled tourists in the market and eliminating the deficiencies of facilities serving in tourism.Perception capability assumes significant importance for human-robot interaction. The forthcoming industrial environments will require a high level of automation to be flexible and adaptive enough to comply with the increasingly faster and low-cost market demands. Autonomous and collaborative robots able to adapt to varying and dynamic conditions of the environment, including the presence of human beings, will have an ever-greater role in this context. However, if the robot is not aware of the human position and intention, a shared workspace between robots and humans may decrease productivity and lead to human safety issues. This paper presents a survey on sensory equipment useful for human detection and action recognition in industrial environments. An overview of different sensors and perception techniques is presented. Various types of robotic systems commonly used in industry, such as fixed-base manipulators, collaborative robots, mobile robots and mobile manipulators, are considered, analyzing the most useful sensors and method
