Environmental Visualization and Exploration in Mobile Augmented Reality Games: Redefining the Spatial Affordances

While spatiality in desktop and console interface video games has been widely studied, not many approaches have been made in the context of mobile augmented reality (MAR), an environment from which popular games such as Pokemon Go have emerged. On the one hand, this paper retakes the notion of spatial affordance that Janet Murray introduced for digital environments and proposes a reinterpretation of the concept throughout the integration of the MAR features. On the other, it seeks to approach the impact that these characteristics have on the gameplay experience. For this purpose, 46 mobile augmented reality video games of different genres were analyzed. The study reveals that augmented reality is still a superfluous element rather than a central aspect of the gameplay in most MAR video games, although trends involving new hybrid game experiences have been observed. Finally, we propose a tool for classifying MAR video games according to two axes that assess up to what extent physical space is integrated into the gameplay: gameworld spaces (representational layer) and gameplay spaces (interactive layer, interaction with the game rules and mechanics).

The robot doesn't lie: real-life validation of robotic performance metrics.

Degree of resident participation in a case is often used as a surrogate marker for operative autonomy, an essential element of surgical resident training. Previous studies have demonstrated a considerable disagreement between the perceptions of attending surgeons and trainees when it comes to estimating operative participation. The Da Vinci Surgical System dual console interface allows machine generated measurements of trainee's active participation, which has the potential to obviate the need for labor intensive direct observation of surgical procedures. However, the robotic metrics require validation. We present a comparison of operative participation as perceived by the resident, faculty, trained research staff observer (gold standard), and robotic machine generated data. A total of 28 consecutive robotic inguinal hernia repair procedures were observed by research staff. Operative time, percent active time for the resident, and number of handoffs between the resident and attending were recorded by trained research staff in the operating room and the Da Vinci Surgical System. Attending and resident evaluations of operative performance and perceptions of percent active time for the resident were collected using standardized forms and compared with the research staff observed values and the robot-generated console data. Wilcoxon two-sample tests and Pearson Correlation coefficients statistical analysis were performed. Robotic inguinal hernia repair cases had a mean operative time of 91.3 (30) minutes and an attending-rated mean difficulty of 3.1 (1.26) out of 5. Residents were recorded to be the active surgeon 71.8% (17.7) of the total case time by research staff. There was a strong correlation (r = 0.77) in number of handoffs between faculty and trainee as recorded by the research staff and robot (4.28 (2.01) vs. 5.8 (3.04) respectively). The robotic machine generated data demonstrated the highest degree of association when compared to the gold standard (research staff observed data), with r = 0.98, p < 0.0001. Lower levels of association were seen with resident reported (r = 0.66) perceptions and faculty-reported (r = 0.55) perceptions of resident active operative time. Our findings suggest that robot-generated performance metrics are an extremely accurate and reliable measure of intraoperative resident participation indicated by a very strong correlation with the data recorded by research staff's direct observation of the case. Residents demonstrated a more accurate awareness of their degree of participation compared with faculty surgeons. With high accuracy and ease of use, robotic surgical system performance metrics have the potential to be a valuable tool in surgical training and skill assessment.

Design Guidelines for the Size and Length of Chinese Characters Displayed in the Intelligent Vehicle’s Central Console Interface

In order to ensure the driver’s safe driving, the human–computer interaction interface of an intelligent vehicle needs to convey important information. The text is an important carrier of this kind of information. The design criteria of English characters have been widely discussed, including the color, meaning, size and length. However, design guidelines for Chinese characters in central consoles of vehicles have rarely been discussed from a human–computer interaction perspective. In this paper, we investigated the size and the length of Chinese characters in the intelligent vehicle’s central control screen, based on international design guidelines and standards. The experiment involved 30 participants performing simulated in-vehicle secondary tasks. The result from the experiments shows that the usability of characters increases and the driver’s workload decreases as the characters get larger and shorter. We also propose a set of recommended values for the size and length of Chinese characters in this context. Future work will focus on providing design guidelines for other aspects of HMI design in intelligent vehicles.

THE CONSTRUCTION METHODS FOR SOFTWARE COMPLEXES BY THE EXAMPLE OF OPEN CROSS-PLATFORM ONLINE SYSTEM FOR TEXT TRANSLATION

Popular online translators Google Translate, Bing Translator, DeepL Translator, and Apertium are reviewed. The goal is to compare the interfaces and functionality of these translators. The advantages of using the C ++ programming language are investigated. The choice of the Qt cross-platform framework among other analogues has been substantiated. Qt most of all meets the requirements set in the article for the development of its own software product. The basis for the development of the program is chosen methods of object-oriented programming using the application programming interface. The stages of development of the online «Crow Translate» system are presented. Its capabilities for text translation are described: an application programming interface for translation, peculiarities of the implementation of a C ++ programming system based on the Qt framework, basic commands of the console interface, functionality of the graphical interface for dubbing and translation, customization options, localization possibilities and ways of distributing the offered «Crow Translate» software. During the development of the system, the implementation of the translation process and the program interface were divided into two separate projects. A peculiarity of the project implementation is the development of a separate QOnlineTranslator library for text translation. This system is free software and is published on the GitHub page under the GPL v3 license for use in any similar projects. The details of the implementation of the suggested library and its main functions are described. Thanks to the use of the Google interface in the described program, a high-quality translation is ensured. The developed project provides for the ability to work in the dictionary mode when entering one word or a piece of text. Various translation options are additionally displayed for one word. There is support for displaying transliteration. When developing a software product, the possibility of receiving a translation in a pop-up window without additional transitions to the browser or other applications was taken into account. The result is an open cross-platform software product that has convenient access to the translation of a text selected in any application and takes up a small amount of RAM.

The Impacts of Touchscreen and Physical Control Interface Characteristics on Driver Distraction and Attention Management

Breakthroughs in interface technologies has encouraged automaker to increasingly replace physical control elements with touchscreens for the center console interface. Whereas the physical elements provide natural haptic and auditory cues supporting interactions even when they are not visually attended to, touchscreen interactions necessitate visual attention because there is not much to feel on the flat screen. Therefore, in-vehicle touchscreens may lead drivers to divert more glances to the touchscreen and away from the roadway, possibly resulting in greater time with eyes off the road and serious safety concerns (Fitch et al., 2013; Olson, Hanowski, Hickman, &amp; Bocanegra, 2009).

Approaches to solving the problem of network communications traffic monitoring and processing of its results

The development of computer networks in the IT industry passes very quickly, trying to satisfy constantly increasing demand for fast and high-quality connection to the global Internet network. That is why, there is a need for the development of the specialized software (sniffer), which would simplify the work of system administrators in debugging of networks and would allow less competent experts in this sphere to start performing such work.The analysis of the systems of analogues, which have a number of disadvantages, the main of which are the presence of console interface only and difficulty of use because of the increased requirements for the user’s knowledge in the field of network technologies was conducted.Some of them support Linux systems only, that makes them unsuitable for the use on most desktop computers. The considered systems do not have the realized construction of graphical results that could be quite a valuable tool in the study of networks. Therefore, there is a need for the development of the specialized software, which would simplify the work of system administrators in debugging of networks and would allow less competent experts in this sphere to start performing such work.The analysis of approaches to the solution of the problem of network traffic monitoring and processing of its results was carried out. Modern network systems and problems, which arise in the study of their condition, were considered.As a result of the analysis of existing methods for the study of network systems it was proposed to use the method of listening to the network interface as the way of the study of network systems for further system administration.
