“…However, the software is still being developed and new functionality is constantly incorporated in order to react to the development in the area of cognitive cartography. Current developmental efforts focus on 3D technology implementation (pilot experimental testing of 3D visualization using web technologies has already been made [85,86]), optimization for tablets or other devices with touch screens [87], interconnection with an eye-tracking system, and further development of a Firefox-based browser. The new application using Firefox was able to replace the original SWT-browser based solution in controlled data collection.…”

Abstract:The article presents a testing platform named Hypothesis. The software was developed primarily for the purposes of experimental research in cartography and psychological diagnostics. Hypothesis is an event-logger application which can be used for the recording of events and their real-time processing, if needed. The platform allows for the application of Computerized Adaptive Testing. The modularity of the platform makes it possible to integrate various Processing.js-based applications for creation and presentation of rich graphic material, interactive animations, and tasks involving manipulation with 3D objects. The Manager Module allows not only the administration of user accounts and tests but also serves as a data export tool. Raw data is exported from the central database in text format and then converted in the selection module into a format suitable for statistical analysis. The platform has many functions e.g., the creation and administration of tasks with real-time interaction between several participants ("multi-player function") and those where a single user completes several tests simultaneously ("multi-task function"). The platform may be useful e.g., for research in experimental economics or for studies involving collaborative tasks. In addition, connection of the platform to an eye-tracking system is also possible.

“…Users need to get the desired information quickly and correctly, so these aspects are considered as the most important attributes of all types of visualizations. Additionally this necessity could be also demanded legislatively (Reznik, 2013 (Kubicek et al, 2014;Sprinarova et al 2015;Herman and Reznik, 2015;Kubicek et al, 2016;Popelka et al, 2016).…”

ABSTRACT:Human-computer interaction has entered the 3D era. The most important models representing spatial information -maps -are transferred into 3D versions regarding the specific content to be displayed. Virtual worlds (VW) become promising area of interest because of possibility to dynamically modify content and multi-user cooperation when solving tasks regardless to physical presence. They can be used for sharing and elaborating information via virtual images or avatars. Attractiveness of VWs is emphasized also by possibility to measure operators' actions and complex strategies. Collaboration in 3D environments is the crucial issue in many areas where the visualizations are important for the group cooperation. Within the specific 3D user interface the operators' ability to manipulate the displayed content is explored regarding such phenomena as situation awareness, cognitive workload and human error. For such purpose, the VWs offer a great number of tools for measuring the operators' responses as recording virtual movement or spots of interest in the visual field. Study focuses on the methodological issues of measuring the usability of 3D VWs and comparing them with the existing principles of 2D maps. We explore operators' strategies to reach and interpret information regarding the specific type of visualization and different level of immersion.

“…This tool is based on open web technologies: HTML (HyperText Markup Language), PHP (Hypertext Preprocessor), JavaScript and JavaScript libraries X3DOM (for 3D interactive visualization) and Hammer.js (for gesture recognition). Principles, advantages, and capabilities of X3DOM are described by Behr et al (2009) or Herman and Reznik (2015). The testing tool record the following characteristics:  The speed of user performance (efficiency) shows how quickly the participant can perform a task.…”

Commission VI, WG VI/4 KEY WORDS: 3D visualization, interaction, human computer interaction, user issues, touch screen. ABSTRACT:The use of both 3D visualization and devices with touch displays is increasing. In this paper, we focused on the Web technologies for 3D visualization of spatial data and its interaction via touch screen gestures. At the first stage, we compared the support of touch interaction in selected JavaScript libraries on different hardware (desktop PCs with touch screens, tablets, and smartphones) and software platforms. Afterward, we realized simple empiric test (within-subject design, 6 participants, 2 simple tasks, LCD touch monitor Acer and digital terrain models as stimuli) focusing on the ability of users to solve simple spatial tasks via touch screens. An in-house testing web tool was developed and used based on JavaScript, PHP, and X3DOM languages and Hammer.js libraries. The correctness of answers, speed of users' performances, used gestures, and a simple gesture metric was recorded and analysed. Preliminary results revealed that the pan gesture is most frequently used by test participants and it is also supported by the majority of 3D libraries. Possible gesture metrics and future developments including the interpersonal differences are discussed in the conclusion.
