<p><strong>Abstract.</strong> Marine leisure sports activities such as sea fishing, skin scuba diving and yacht sailing are affected by sea conditions such as waves and tides, and weather conditions, as well as by marine traffic. Timely provision of such high accuracy maritime information is very important because that affects the safety of people engaged in leisure activities. Safety information for marine leisure activities includes obstacle information such as the position of other ships and sea reefs and rocks in the vicinity, weather conditions. If marine leisure activists can identify and use various safety-related information around them, it will be a great help to carry out safe marine leisure activities. The geographic visualization environment provides users with the ability to intuitively and easily convey complex information. Therefore, mobile location-based services based on geographical visualization utilizing complex maritime safety information have the advantage of effectively providing the information necessary for people engaged in safe marine leisure activities.</p><p>In this study, we developed a location-based mobile application based on geographic visualization that support safe marine leisure activities by integrating ship navigation information, marine chart(map), and ocean weather information. The mobile geographical visualization service has a function to effectively integrate various type of data related to marine safety and transmit the fused information to users in order to support safe leisure activities. First, location of ships around the user's location is transmitted from AIS server and displayed on the map. Since the ship type, speed, and direction information are displayed on the map, the user can check the position of the ships operating in the vicinity. Second, since the ocean weather information such as wave, current, temperature, wind speed is received from the server and displayed on the map, the safety can be grasped by using the ocean condition and weather information in real time. The integrated marine safety information is visualized in mobile devicess in two ways. The first method is in which graphs, icons, and images are displayed on a two-dimensional marine chart(map). The second scheme utilizes a location based Augmented Reality(AR) technique. If the user directs the camera of the mobile device to a certain direction or point, safety information of the point can be expressed on the device. For example, when the user directs the camera of the mobile phone to a ship in the vicinity, information on the speed, moving direction, and type of the ship can be displayed on the mobile phone.</p><p>The contributions of this study are as follows. First, we proposed a novel method to visualize various location-based maritime safety information on mobile devices. Map information of marine charts, weather information expressed in graphic format, and vessel information represented by icons are effectively fused and visualized on the limited display of mobile devices. Second, information transmission channel is diversified by integrating marine safety information by 2D maps and location based AR. The user can utilize either of the 2D maps or 3D AR by the purpose and the kind of the safety information. To build an environment that can consistently convey the same marine safety information in 2D maps and 3D AR remains as a challenge to extend the application of this study for the future.</p>

The paper describes the application of augmented reality tools to create an auxiliary interactive tool in the field of design. To mediate it, an application with AR operation based on marker tracking has been designed. The created application works with the mobile devices platform. Two types of markers have been used in the application. To display basic information, buttons with functions are added to the scene, such as part information, rotation and change of position in the X, Y, Z direction. The application runs on a mobile phone, with a built-in camera. The marker is displayed in the drawing's lower left corner. The model is positioned so that it appears above the view of the part in the drawing. The task of the application is to support intelligent tools applicable in the design stage of production preparation, in the creation of drawing documentation.

Abstract Recent studies have begun to address the importance of weather information for leisure activities. This paper contributes to the understanding of how weather information is sourced, perceived, and used for the discretionary and weather-dependent winter activities of skiing, snowboarding, and snowmobiling. A survey of 1948 Ontario (Canada) skiers/snowboarders and snowmobilers is the empirical basis for the paper, providing insights into how winter recreationists are both similar to and different from the general public with respect to weather information. Results show that virtually all (≥97%) skiers/snowboarders and snowmobilers use weather forecasts when planning an outing, which are primarily (≥95%) sourced through Internet and mobile devices. Skiers/snowboarders and snowmobilers are also highly attentive to rain and freezing rain variables in the forecast, as it negatively affects participation. The results also demonstrate the importance of forecast use for planning travel to snow resorts and snowmobile trails, with poor road conditions likely to result in a postponed or cancelled trip. These findings underscore the differing weather needs of subpopulations, with the need for continued research to examine variations among weather forecast users for context specific decision making.

The topic of the use of mobile devices and headphones on pedestrian crossings is much less explored in comparison to the use of the mobile phone while driving. Recent years have seen many discussions on this issue, especially in foreign countries. The Slovak Republic, however, has not been giving it enough attention (and it is not mentioned in the National Road Safety Plan for the Slovak Republic from 2011 to 2020). This paper aims to draw attention to this issue. It presents basic outputs of a pilot study on pedestrian safety, with a focus on the use of mobile devices and headphones at selected non-signalized pedestrian crossings in three Slovak cities. Overall, 9% of pedestrians used headphones or mobile devices at observed pedestrian crossings (4% of them used headphones, 1% used headphones and at same time used their mobile phone, 2% made phone calls and 2% used their mobile phones). While these numbers can be considered relatively low, the study proved that during weekdays every 2 min someone was using the crossing without fully focusing on crossing the road safely. Another main finding was that although the safety risk at pedestrian crossings is increased by factors such as rush hour traffic or reduced visibility, pedestrian behavior related to the use of mobile phones and headphones does not change. A safety assessment was also carried out at the crossings. The results show that pedestrian behavior is not affected by the level of safety of the crossing (e.g., visibility of the crossing for drivers). The results of the presented analysis suggest that action is needed to change that. Due to the lack of information about accidents involving pedestrians using mobile phones and headsets when crossing the road, no relevant statistical data could be analyzed. The dataset collected can be used as a basis for further investigation or comparisons with other countries of the relevant indicators. In future work, we would like to include a pedestrian–driver interaction factor focusing on driver speed behavior in relation to pedestrians (who are on or are about to step onto a pedestrian crossing) and identify critical situations caused by improper behavior of drivers and/or pedestrians. This will help to understand speed adjustment problems related to pedestrian crossings.

AbstractIn the Internet of Things (IoT) era, the capacity-limited Internet and uncontrollable service delays for various new applications, such as video streaming analysis and augmented reality, are challenges. Cloud computing systems, also known as a solution that offloads energy-consuming computation of IoT applications to a cloud server, cannot meet the delay-sensitive and context-aware service requirements. To address this issue, an edge computing system provides timely and context-aware services by bringing the computations and storage closer to the user. The dynamic flow of requests that can be efficiently processed is a significant challenge for edge and cloud computing systems. To improve the performance of IoT systems, the mobile edge orchestrator (MEO), which is an application placement controller, was designed by integrating end mobile devices with edge and cloud computing systems. In this paper, we propose a flexible computation offloading method in a fuzzy-based MEO for IoT applications in order to improve the efficiency in computational resource management. Considering the network, computation resources, and task requirements, a fuzzy-based MEO allows edge workload orchestration actions to decide whether to offload a mobile user to local edge, neighboring edge, or cloud servers. Additionally, increasing packet sizes will affect the failed-task ratio when the number of mobile devices increases. To reduce failed tasks because of transmission collisions and to improve service times for time-critical tasks, we define a new input crisp value, and a new output decision for a fuzzy-based MEO. Using the EdgeCloudSim simulator, we evaluate our proposal with four benchmark algorithms in augmented reality, healthcare, compute-intensive, and infotainment applications. Simulation results show that our proposal provides better results in terms of WLAN delay, service times, the number of failed tasks, and VM utilization.

Marine Safety Information is defined as the coordinated service of navigational and meteorological warnings, meteorological forecasts and distress alerts.It represents the core information which the Master of a ship is required to receive under the provisions of chapters IV and V of the Safety of Life at Sea Convention (SOLAS).In essence these cover the responsibilities of nations to broadcast messages relating to marine hazards, the obligation placed upon Masters to report such hazards, and to receive messages broadcast about them.Three separate kinds of information are dealt with in the SOLAS Convention. First, Meteorological Services: these are the business of the World Meteorological Organization (WMO), which seeks to coordinate the work of various national meteorological administrations. Unfortunately a multitude of overlapping services and areas have grown up out of an expanding practical requirement and capability. This has resulted in overlap of services and consequent multiplication of effort.

&lt;p&gt;In June 2018 at Slovenian Environmental Agency (ARSO) the internal project SPOMIN was started. In Slovenia, weather forecasters have only one operational shift per day, which lasts 12 hours, and only one weather forecaster is mostly responsible for general forecasts for the entire country. Dedicated forecasts for special users are fragmented and delegated to teams across the Agency; in most cases there is only one person responsible for each specific topic, and some forecasts for specific activities are not even produced, for example for leisure activities, skiing, surfing, etc. Therefore, the aim of SPOMIN project was to harmonize operational meteorological information and forecasts and collect their production in one team.&lt;/p&gt;&lt;p&gt;For the SPOMIN proposes, we issued a questionnaire addressed to our users and received more than 1000 answers, many of them were descriptive. Many of our users are familiar with our special products for users, but they are missing additional graphic representation or explanatory text or more details related to their activity. There are also some of users who are unaware of our products as they are not easy to find on our websites. Our users know what kind of information and forecasts they are missing, and they provided us with a lot of ideas how to improve our products and which new products should we develop in future. Thus, the project team suggested some new products and upgrade of existing ones. While the project was finished in 2020, the conclusions and results were conveyed to the newly formed team for specific forecasts.&lt;/p&gt;&lt;p&gt;At present, we are not able to enrich the content of our web site with new kinds of information, because the web site is currently under renovation. To overcome this situation, we have started adding more information to the social network where we have over 20,000 followers, recording podcasts with highly relevant topics, producing lots of interesting infographics, and so on. Our plans for the future include production of videos with forecasts and meteorological educational content. Of course, we will upgrade and implement the ideas developed in SPOMIN project and integrate them on our new website which will be much more user oriented as it is the current one.&lt;/p&gt;&lt;p&gt;Selected examples of tailored information for users published on our social media will be presented.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;
