It is indisputable that they can encounter challenges even in everyday traffic situations. An environment which is not unobstructed can make it impossible for a visually impaired person to approach it unaided. They are only able to use it independently when strict conditions are met in pedestrian crossing points without traffic control equipment. SafeXOne [1] is a smart pedestrian crossing system designed for roads without traffic control equipment. Our goal was to design an addition that supports the visually impaired in their orientation, mainly through a voice-based solution. It would allow for the proper recognition of the crossing point, i.e., the orientation of the individual. We want to help the visually impaired with supplemental light signals as well. In addition, we use the basic warning signals of the SafeXOne system to enhance security.; The aim of our research is to promote equal opportunities for the blind and visually impaired.

Digital Photogrammetric Workstations (DPWs) are offering to cover the whole process starting from the camera calibration until gaining the ground coordinates of points for mapping, for 3D models and for producing orthophotos. To achieve the final products in the image evaluation with high accuracy, the error detection is an essential part in each step. The paper summarizes the error detection methods and solutions for correcting the final products in photogrammetry.; The error detection plays an important role in the photogrammetric evaluation process.

Both classical methods for mechanical cameras and new methods for digital cameras are reviewed. Real measurements illustrate that the potential accuracy of novel methods is in the range of microseconds.; In this paper various methods are presented for measuring the shutter speed of cameras.

Also, the most challenging in defense side to raise awareness of the employees, but these employees most of their time are people who are enjoys the benefits of technology and uses it in their private life. Recently, according to IT Security Technology evolution, from Information System perspective, the human is the weakest link. This is supported by increased Social Engineering activity due pandemic reasons. This paper reviews the recent attacks and techniques according to increased e-commerce, internet and mobile activity. The goal of this review is to highlight how the usage of Information Technology and Information Communication Technology changed and review the connected fields, specially, the change in human side. This review defines new ways to achieve safe and secure usage through Information Technology Safety Awareness beyond Company Policy driven Information Security Awareness which is predefined in NIST SP-800-50 in 2003. The NIST standard suggests awareness training where it blurs compliance with corporate policy and basic, user knowledge. This review points out is that blending Information Technology Safety Awareness is problematic and straightening it up is a possible way to make user insecurity less of a problem.; The majority of cyberattacks are targeting companies, government or service provider parties, but attacks and threats are not limited to these parties.
