ABSTRACT
COVID-19 has led to a rapid increase in the use of video conferencing and video calls over the Internet. In this paper, we propose a low-cost, portable, and highly confidential occupied information environment. The authors developed a secure input/output device in the NICT's 'SecHack365' program for fostering young security innovators. By improving the device and integrating it with traditional Japanese culture, we quanti-tatively evaluated that the device can achieve sufficient up-time, lightweight that does not burden the body, and has a price that does not strict on the wallet. © 2022 IEEE.
ABSTRACT
Images reproduced for different output devices are known to be limited in the range of colours that can be reproduced. It is accepted that reproductions made with different print processes, and on different substrates, will not match, although the overall reproduction appearance can be optimized using an output rendering. However, the question remains: how different are they visually? This paper reports on a pilot study that tests whether visual difference can be reduced to a single dimensional scale using magnitude estimation. Subject to recent Covid restrictions, the experiment was moved from the lab to an online delivery. We compare the two methods of delivery: in-person under controlled viewing conditions, and online via a web-based interface where viewing conditions are unknown. © 2021 Society for Imaging Science and Technology.
