The rapid development of aviation technology entails the need to increase the quality of ergonomic support. This is due to the fact that for the safe implementation of activities, the pilot has to use the entire amount of attention, not rarely, at the limit of his capabilities. The color of the instrument scales, the contrast of the information feed, and other information perception conditions can significantly complicate the evaluation of the flight instrument readings. This is especially true with the transition of most modern aircraft from analog display of instrument readings to digital. The study examines the features of perception of digital information by operators of aviation profile with different color background of the stimulus material. The analysis of the results of the solution by operators of 3 Schulte tables and 3 SchultePlatonov tables on the combined hardware complex NS-Psychotest with the system of fixing the coordinates of the eye-stationary eye tracking RED250mobile eye tracking device. When performing the eye search function, the number of visual fixations and the task completion time were calculated. It was found that when searching for digital values on Schulte tables with a white background, the number of eye fixations was less than when performing a similar task on black-and-red SchultePlatonov tables. Accordingly, it also took less time to solve black-and-white tables. A trend was found showing that the search for digital values represented in the SchultePlatonov tables on a red background was carried out by operators faster than on a black background. Further study of this topic can contribute to the development of proposals for ergonomic support of aircraft, which in turn will help to maintain the reserves of attention of operators in a continuous stream of incoming data (2 figures, 1 table, bibliography: 13 refs).

Considers the influence of the degree of extraversion on the perception of digital information by aviation operators. The analysis of the results of solving the Schulte tables by the test subjects on the NS-Psychotest hardware complex based on the recording of the eye track, performed using a stationary eye tracking device RED250mobile eye tracking device was carried out. While performing the search function, the number of saccadic movements, their amplitude, and the search time for a given digital value were registered. It has been revealed, that introverts during realization eyes search function perform less saccadic movements and spend less time on it than extraverts do. Significant differences have been found during resolving search tasks depending on degree of extraversion. Some interconnections of extension the latent period of the saccade with complication of solving process the cognitive problem were also found. It was found out, that increase in speed of saccadic movements of eyes leads to low efficiency of results of search task execution. Results of conducted research emphasize value of individual approach to medical flight service taking into account psychological features of flight crew in conditions of rapid progress in aviation technologies and means of visualisation of flight information. The obtained data reveal some features of information perception by operators of complex ergatic systems, the study of which in the future will help to maintain the reserves of attention in a continuous stream of incoming data, and thereby reduce the load on the visual analyzer and increase the reliability of professional activities of flight crew.

AbstractThis paper presents results of the effect of different translation modalities on users when working with the Microsoft Word user interface. An experimental study was set up with 84 Japanese, German, Spanish, and English native speakers working with Microsoft Word in three modalities: the published translated version, a machine translated (MT) version (with unedited MT strings incorporated into the MS Word interface) and the published English version. An eye-tracker measured the cognitive load and usability according to the ISO/TR 16982 guidelines: i.e., effectiveness, efficiency, and satisfaction followed by retrospective think-aloud protocol. The results show that the users’ effectiveness (number of tasks completed) does not significantly differ due to the translation modality. However, their efficiency (time for task completion) and self-reported satisfaction are significantly higher when working with the released product as opposed to the unedited MT version, especially when participants are less experienced. The eye-tracking results show that users experience a higher cognitive load when working with MT and with the human-translated versions as opposed to the English original. The results suggest that language and translation modality play a significant role in the usability of software products whether users complete the given tasks or not and even if they are unaware that MT was used to translate the interface.

Perception of different color contrast stimuli was studied in the presence of light scattering: in a fog chamber in Clermont-Ferrand and in laboratory conditions where light scattering of similar levels was obtained, using different light scattering eye occluders. Blue (shortest wavelength) light is scattered in fog to the greatest extent, causing deterioration of vision quality especially for the monochromatic blue stimuli. However, for the color stimuli presented on a white background, visual acuity in fog for blue Landolt-C optotypes was higher than for red and green optotypes on the white background. The luminance of color Landolt-C optotypes presented on a LCD screen was chosen corresponding to the blue, green, and red color contributions in achromatic white stimuli (computer digital R, G, or B values for chromatic stimuli equal to RGB values in the achromatic white background) that results in the greatest luminance contrast for the white–blue stimuli, thus advancing the visual acuity for the white-blue stimuli. Besides such blue stimuli on the white background are displayed with a uniform, spatially unmodulated distribution of the screen blue phosphor emission over the entire area of the screen including the stimulus C optotype area. It follows that scattering, which has the greatest effect on the blue component of screen luminance, has the least effect on the perception of white–blue stimuli.

Introduction. The use of technical means for copyright protection is regulated not only in Russian legislation, but also in foreign and international law. It means that the international concept of intellectual property protection could be perceived differently by foreign jurisdictions, which, in turn, is of special scientific interest. The foundations of legal regulation are laid down in international treaties, which in the intellectual property law are tools that contain substantive rules of law. The provisions of such treaties are implemented in the national (supranational) legislation, and, therefore, become part of them and subject to additions.. The article is devoted to the study of international legal regulation of the use of technical means for copyright protection.Materials and methods. The methodological basis of the research consists of the following general scientific and special methods of cognition of legal phenomena and processes: dialectical, formal-legal, comparative-legal, formal-logical, structural-functional.Results of the study. The authors found that attempts to protect copyright using technology available at every stage of history were undertaken by individual countries, beginning from the second half of the 19th century. However technical means of protection received legal regulation at the international level relatively recently, the prerequisite for that was the rapid development of digital information technologies. Analysis of international legal norms in the field of legal regulation of technical means of copyright protection has shown that at present international legal regulation is of a general nature, providing each of the states at the national level with ample opportunities for legal concretization of gen-eral norms. However, recently the Internet treaties of WIPO recognized for the first time not only the advisability of the use of technical means of protection, but also the obligation prohibiting circumvention of such protection technologies, and therefore national legislations should contain provisions regulating the circumvention of such protection technologies.Discussion and Conclusions. The introduction of international law with regard to the use of the protection technologies, despite their general and abstract nature, has given a serious impetus to the establishment of legal regulation of this institution at the national level. At the same time, the rules governing the use of the protection technologies in the near future will require greater unification and concretization due to the rapid development of digital information technologies, blurring the borders between states in terms of disseminating the results of intellectual activity, and also in order to avoid a multiplicity of interpretation of law and to ensure effective legal regulation and protection of copyright.

Digital camera which has the advantage of real-time image transferring and easily processing is more and more widely used in the packaging and printing industry with the rapid development of high-tech electronics industry. However, the color in digital camera is not accurate which affect the application. To minimize the color difference between the color in the digital camera and the real color, the color reproduction methods is developing. The field comparative experiment is carried out to compare the performance of color reproduction methods, such as polynomial regression algorithm in different color space, and color checker passport. The results show that fourth order polynomial regression color reproduction in XYZ color space has the best performance.

During the decade of 1990s the term digital libraries become a recognized phrase for describing libraries that offer access to digital information by using a variety of networks, including internet and world wide web. Other synonyms used interchangeably with digital libraries are library without walls and electronic and virtual libraries because every online or virtual source of information is electronic source of information but every electronic information sources are not online or virtual form, so digital or electronic library includes digital contents and that can be delivered any time anywhere to the networked computer. Digital libraries provide remote access to the contents and the services of the libraries and other information sources combining an onsite collection of current and heavily used materials in both print and electronic form with an electronic networks which provide access to and delivery for worldwide libraries and commercial information and knowledge sources. Basically the digital libraries are the metaphor for the networked libraries. In the light of this therefore, this chapter discussed digital libraries as information superhighway looking at issues like factors responsible for the emergence of digital libraries, influence internet on digital libraries, etc.

1. Response properties and spectral sensitivities of a functional class of medulla neurons that received dominant input from a single stemma in the swallowtail butterfly larva were examined with regard to neutral and chromatic backgrounds. 2. Eight types of neurons were dominated by a dichromatic stemma with blue and green receptors. Six showed specific color-opponent responses mediated by two receptors on different backgrounds; one showed strong color opponency because of fairly balanced antagonistic input on the neutral (dark and white) background; the other five usually had weak or concealed color opponency on a neutral background but became strongly color opponent when appropriate chromatic illumination was present on the background. The most complex neuron gave excitatory responses on a dark background, inhibitory responses on a white background, and color-opponent responses on a chromatic (yellow) background. 3. The remaining two types of neurons dominated by the dichromatic stemma showed non-color-opponent and broad action spectra ascribable to a synergistic effect of the two classes of photoreceptors. 4. All eight types of neurons dominated by a trichromatic stemma (with UV, blue, and green receptors) were color opponent. Five showed strong color-opponent responses with the mediation of the three classes of receptors or only two (UV and green) on a neutral background. The others revealed distinct color opponency in the presence of UV or green illumination on the background. 5. The larval medulla neurons described may form parallel, elementary color-coded channels in the medulla neuropile to combine the outputs of the different color receptors in a single visual unit (stemma) into specific color-opponent signals. They probably correspond to columnar relay neurons in the medulla of the adult insects with a compound eye.

Safety signs play a very important role in people’s evacuation during emergencies. In order to explore the appropriate color for subway safety signs, four safety signs of different color combinations are designed, and the virtual reality, eye-tracking technology, and physiological indicator measurement are used in a virtual subway fire escape experiment. A total of 96 participants with equal distribution in gender and four different color combination groups were recruited. Participants’ eye-tracking and physiological data (heart rate, skin conductance) were real-time recorded through ErgoLAB V3.0 in the whole experiment. The relationship between Color_of_safety_sign and escape performance, eye-tracking indicators, and physiological indicators is discussed respectively through SPSS. The results show that “Green and black” group has the best evacuation escape performance, low cognitive load, high search efficiency on safety signs, and the highest stress level and immersion and “Green and black” can be the most appropriate color for safety sign. This research is of certain significance for improving the function of subway fire-fighting infrastructure and the resilience of the metro system. Moreover, it can provide references and advice on risk management, emergency evacuation, and so on.
