With the development of electronic communication technology, the ship' s navigational equipment is being digitized, and it has being studied touch-screen-based navigation user interface. However, due to the influence of environmental factors such as waves, it has a potential problem hazardous marine accident occurs due to incorrect operation, the systematic research in consideration of this be done do not. In this paper, we provide a user interface experimental model to verify the stability that takes into account the external environment of the touch-screen input on. Further, we simulated to verify that the interface of the touch screen, the effect of applying the input delay time and the size of the button is obtained through the experimental model proposed. It will be able to greatly contribute to studies of the interface robust touch screen user errors that can be analyzed by the experimental model is proposed to improve the ship, the overall system stability.
Due to the technological advance, people can enjoy 3D contents at home through 3D TV. This means that people can more easily access 3D contents nowdays. Considering the fact that visual discomfort caused from 3D environment was still unsolved, it is important to investigate the effect of repeated exposure to 3D contents on visual discomfort. In the present study, visual discomfort was measured through three different sessions with intervals of one and half months. In each session, while viewing 3D video clips for 80 minutes, participants were asked to press button whenever they felt discomfort. While the results showed a general tendency of decrease in button press, it was also found that there were individual differences. A rapid reduction in button press was found over repeated exposure in the results from participants with higher button press during the first session. A small increase in button press, however, was found in the results from participants with lower button press. Further studies should be needed to elucidate the characteristics of those potential risk individuals.
The purpose of this study is to design a system that can be used for military simulation and virtual training using the location information of individual soldier's weapons. After acquiring the location information using Arduino's GPS shield, it is designed to transmit data to the Smartphone using Bluetooth Shield, and transmit the data to the server using 3G/4G of Smartphone in real time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
