— Current research shows that visual accessibility assessment in the built environment typically considers objectively measurable parameters. However, considering subjective visual perception for architectural characteristics is extremely important. Visual perception can vary depending on environmental factors and personal factors and is particularly relevant for people with low to mild visual impairments. This explorative research studied the current state of the art of tools and systems that support the assessment of visual accessibility and investigated new ways of experiencing visual accessibility in the built environment. After identifying gaps in the current scenario, the Cambridge simulation glasses were selected as a tool to simulate visual impairments and therefore experience visual accessibility in the built environment. A pilot study was conducted by navigating a publicly accessible building and experiencing how clearly visible certain architectural characteristics were, while walking with and without wearing the glasses. The goal of this study was to understand their potential use in different settings and explore how to offer an empathic experience of visual accessibility with a low-cost tool for different stakeholders.
This study attempted to identify the information gap about Internet of Things (IoT) devices and services in the era of digital transformation. To this end, we analyzed differences in perception of predicting future issues about IoT devices and services, and analyzed differences in the need for digital technology and help in life according to perceptions and experience of using IoT devices and services. Also, the level of education and demand for education were analyzed. A survey was conducted from February 15th to March 7th
As modern vehicles are complex IoT devices with intelligence capable to connect to an external infrastructure and use Vehicle-to-Everything (V2X) communication, there is a need to secure the communication to avoid being a target for cyber-attacks. Also, the organs of the car (sensors, communication, and control) each could have a vulnerability, that leads to accidents or potential deaths. Manufactures of cars have a huge responsibility to secure the safety of their costumers and should not skip the important security research, instead making sure to implement important security measures, which makes your car less likely to be attacked. This paper covers the relevant attacks and threats to modern vehicles and presents a security analysis with potential countermeasures. We discuss the future of modern and autonomous vehicles and conclude that more countermeasures must be taken to create a future and safe concept.
The Very Large Internet of Things (VLIoT) workshop aims at discussing the solutions of problems arising especially for large-scale Internet-of-Things (IoT) configurations. After online conferences and workshops are becoming the normal mode for running scientific events, after continuously monitoring the global COVID-19 pandemic this year with falling incidence rates in the last times due to vaccination successes, the workshop changes the format the first time to a hybrid event. This ensures that still problems are overcome like travel restrictions, but offers face-to-face discussions among those going to the local event. A hybrid format has still chances like an increased number of participants, less travel burdens and saving budget, but offers the possibility for going to the local event already for a large portion of the participants. Hence we received many high-quality submissions, from which we accepted 9 to be introduced in this editorial.
