Abstract

Object manipulation is one of the most fundamental tasks in 3D user interfaces. Compared with interacting with objects within reach, remote object manipulation is often more challenging, which is often an iterative process that need clutching. However, while there are many interaction techniques designed for manipulating remote objects, it is not well studied the effects of clutching mechanism on remote object manipulation tasks. In this paper, we present a controlled experiment to evaluate the effects of two clutching mechanisms (Normal Clutching vs. Easy Clutching) on 3-DOF translation, 3-DOF rotation and 6-DOF docking tasks under various tasks settings. The results show that easy clutching can significantly save more completion time and clutching time compared with Normal Clutching. In addition, the results also reveal that easy clutching can be more effective especially when dealing with hard tasks and long user-target distance. We also find that users prefer easy clutching over Normal Clutching, indicating that well designed clutching mechanism can effectively improve user experience in manipulation tasks.

Abstract

In recent years, the tourism industry has undergone substantial transformations, integrating new technology to lead to a new era termed Tourism 4.0. These innovations enhance the customer's travel experience. An emerging trend in travel technology is the application of virtual and augmented reality, facilitating virtual tours that allow tourists to explore destinations without physically being there. We present the experience of developing 360 ∘ virtual tours for reserves and natural parks across the four provinces of the Maule Region in Chile including information, 360 ∘ images and videos, as well as several other interactions. A descriptive and correlational analysis was carried out with a total of 147 participants that evaluated the virtual tour, showing a positive correlation between the perceived attractiveness of the 360 ∘ experience and behavioral intention. Participants had an overall positive perception of the virtual experience; they found it involving and attractive, felt immersed in the environment, and were able to make decisions and interact with static and dynamic objects. The contributions of the present work are as follows: the process and what has been learned and can be recommended based on the experience for developing 360 ∘ virtual tours, combining dynamic and stationary elements in 360 ∘ in a virtual experience, and the results of an exploratory study that present the interaction with and user perceptions of the virtual environment.

Abstract

Visual feedback can help users understand the function, state, and outcome of a system during the pre‐, mid‐, and post‐interaction phases. Current visual feedback in 3D visualization scenarios takes less account of information transfer in terms of appearance design and dynamic behavior, which results in visual feedback being presented in a more engineered form and conveying simple information. For these issues, we proposed the concept and method of functional narrative animation as visual feedback for interactions in 3D visualization. We also provided a set of Unity‐based animation library and a plugin tool for configuring the animations. Finally, through user experiments and interviews, we analyzed the role of functional narrative animation as in the interactive visual feedback for 3D visualizations and make corresponding design recommendations.

Abstract

Denna studie undersöker användarpreferenser och utmaningar kopplade till horisontella gränssnitt som använder vertikala skrollningsmekanismer på webbplatser. I det snabbt föränderliga digitala landskapet ökar förekomsten av horisontella gränssnitt, särskilt på webbplatser som använder horisontella layouter samtidigt som de behåller traditionella vertikala skrollningsmekanismer. Studien syftar till att analysera användarupplevelser vid sådana gränssnitt med fokus på användarattityder mot vertikal skrollning på horisontellt orienterade webbplatser samt dess inverkan på användbarhet och användarupplevelse.Forskningen innefattade utvecklingen av en prototypwebbplats med ett horisontellt gränssnitt och genomförandet av användartester. Deltagarna interagerade med prototypen genom att använda Tänka Högt-protokoll och System Usability Scale (SUS) vilket gav insikter i deltagarnas uppfattningar och erfarenheter. Resultaten visade blandade attityder mot horisontell skrollning, påverkade av faktorer som mentala modeller, feedbackmekanismer och personliga preferenser. Studien belyser vikten av att anpassa gränssnittsdesignen efter användarförväntningar och feedbackens roll i att förbättra användarupplevelsen., This study investigates user preferences and challenges associated with horizontal interfaces that use vertical scrolling mechanisms on websites. In the rapidly changing digital landscape, the prevalence of horizontal interfaces is increasing, especially on websites that use horizontal layouts while retaining traditional vertical scrolling mechanisms. The study aims to analyze user experiences with such interfaces, focusing on user attitudes towards vertical scrolling on horizontally oriented websites and its impact on usability and user experience.The research included developing a prototype website with a horizontal interface and conducting user tests. Participants interacted with the prototype using the "Think Aloud" protocol and the System Usability Scale (SUS), providing insights into their perceptions and experiences. The results showed mixed attitudes towards horizontal scrolling, influenced by factors such as mental models, feedback mechanisms, and personal preferences. The study highlights the importance of adapting interface design to user expectations and the role of feedback in enhancing user experience.

Abstract

Despite a broad range of mobile AR applications available to date, the majority still primarily use surface gestures, i.e., gesturing on the touch screen surface of the device and do not utilise the affordance of three-dimensional user interaction that AR interfaces support. In this research, we compared two methods of gesture interaction for mobile AR applications: Surface Gestures and Motion Gestures, which take advantage of the spatial information of the mobile device. We have conducted two user studies: an elicitation study (n = 21) and a validation study (n = 10). The first study elicited two sets of 504 gestures, surface and motion gestures, for 12 everyday mobile AR tasks. The two sets of gestures were classified and compared in terms of goodness, ease of use, and engagement. As expected, the participants’ elicited surface gestures are familiar and easy to use, while motion gestures were found more engaging. Using design patterns derived from the elicited motion gestures, we proposed a novel interaction technique called “TMR” (Touch-Move-Release). Through validation study we found that the TMR motion gesture enhanced engagement and provided a better game experience. In contrast, the surface gesture provided higher precision resulting in higher accuracy and was easier to use. Finally, we discuss the implications of our findings and give our design recommendations for using the elicited gestures.

Abstract

Virtual reality (VR) has seen increased use for training and instruction. Designers can enable VR users to gain insights into their own performance by visualizing telemetry data from their actions in VR. Our ability to detect patterns and trends visually suggests the use of data visualization as a tool for users to identify strategies for improved performance. Typical tasks in VR training scenarios are manipulation of 3D objects (e.g., for learning how to maintain a jet engine) and navigation (e.g., to learn the geography of a building or landscape before traveling on-site). In this paper, we present the results of the RUI VR (84 subjects) and Luddy VR studies (68 subjects), where participants were divided into experiment and control cohorts. All subjects performed a series of tasks: 44 cube-matching tasks in RUI VR, and 48 navigation tasks through a virtual building in Luddy VR (all divided into two sets). All Luddy VR subjects used VR gear. RUI VR subjects were divided across three setups: 2D Desktop (with laptop and mouse), VR Tabletop (in VR, sitting at a table), and VR Standup (in VR, standing). In an intervention called “Reflective phase,” the experiment cohorts were presented with data visualizations, designed with the Data Visualization Literacy Framework (DVL-FW), of the data they generated during the first set of tasks before continuing to the second part of the study. For Luddy VR, we found that experiment users had significantly faster completion times in their second trial (p = 0.014) while scoring higher in a mid-questionnaire about the virtual building (p = 0.009). For RUI VR, we found no significant differences for completion time and accuracy between the two cohorts in the VR setups. however, 2D Desktop subjects in the experiment cohort had significantly higher rotation accuracy as well as satisfaction (protation = 0.031, psatisfaction = 0.040). We conclude with suggestions for adjustments to the Reflective phase to boost user performance before generalizing our findings to performance improvement in VR with data visualizations.

Abstract

To incorporate immersive technologies as part of the educational curriculum, this article is an endeavor to investigate the role of two affordances that are crucial in designing embodied interactive virtual learning environments (VLEs) to enhance students’ learning experience and performance: 1) the sense of presence as a subjective affordance of the VR system, and 2) bodily engagement as an embodied affordance and the associated sense of agency that is created through interaction techniques with three-dimensional learning objects. To investigate the impact of different design choices for interaction, and how they would affect the associated sense of agency, learning experience and performance, we designed two VLEs in the context of penetrative thinking in a critical 3D task in geosciences education: understanding the cross-sections of earthquakes’ depth and geometry in subduction zones around the world. Both VLEs were web-based desktop VR applications containing 3D data that participants ran remotely on their own computers using a normal screen. In the drag and scroll condition, we facilitated bodily engagement with the 3D data through object manipulation, object manipulation. In the first-person condition, we provided the ability for the user to move in space. In other words, we compared moving the objects or moving the user in space as the interaction modalities. We found that students had a better learning experience in the drag and scroll condition, but we could not find a significant difference in the sense of presence between the two conditions. Regarding learning performance, we found a positive correlation between the sense of agency and knowledge gain in both conditions. In terms of students with low prior knowledge of the field, exposure to the VR experience in both conditions significantly improved their knowledge gain. In the matter of individual differences, we investigated the knowledge gain of students with a low penetrative thinking ability. We found that they benefited from the type of bodily engagement in the first-person condition and had a significantly higher knowledge gain than the other condition. Our results encourage in-depth studies of embodied learning in VR to design more effective embodied virtual learning environments.

Abstract

Abstract Interacting with digital contents in 3D is an essential task in various applications such as modeling packages, gaming, virtual reality, etc. Traditional interfaces using keyboard and mouse or trackball usually require a non-trivial amount of working space as well as a learning process. We present the design of EZ-Manipulator, a new 3D manipulation interface using smartphones that supports mobile, fast, and ambiguity-free interaction with 3D objects. Our system leverages the built-in multi-touch input and gyroscope sensor of smartphones to achieve 9 degrees-of-freedom axis-constrained manipulation and free-form rotation. Using EZ-Manipulator to manipulate objects in 3D is easy. The user merely has to perform intuitive singleor two-finger gestures and rotate the hand-held device to perform manipulations at fine-grained and coarse levels respectively.We further investigate the ambiguity in manipulation introduced by indirect manipulations using a multi-touch interface, and propose a dynamic virtual camera adjustment to effectively resolve the ambiguity. A preliminary study shows that our system has significant lower task completion time compared to conventional use of a keyboard–mouse interface, and provides a positive user experience to both novices and experts.

Abstract

We propose a new method to recognize gestures from sound waves. The main contribution of this paper is to recognize gestures based on the analysis of short-time Fourier transforms (STFT) using the Doppler effect to sense gestures. To do this, we generate an inaudible tone, which gets frequency-shifted when it reflects off moving objects like the hand. We measure this shift with the microphone to infer various gestures. Experimenting method and evaluating results by using the hand gestures of many different people to browse applications such as website, document and images in the browser on the computers in the classroom and library environment for accurate results. In addition, we describe the phenomena and recognition algorithm, demonstrate a variety of gestures, and present an informal evaluation on the robustness of this approach across Laptop device and people.

Abstract

The demand in the biomedical field for fast and precise devices for in vitro applications has increased in recent years. Mobile microrobots are significantly suitable for such applications and are developing rapidly. These microrobots offer untethered actuation toward a contamination-free environment while allowing for fast and precise handling of biological entities for applications such as positioning, sensing, delivery, and cell surgery that are highly effective for new drug discoveries and improving our understanding of cells’ behavior on the single-cell level. Here, we present a review of the recent state of the art in the actuation and implementation of mobile microrobots for in vitro applications. We first explore the widely used methods of wireless actuation. Next, we address the challenge of implementing an on-board interaction technique to handle the target biological entity without affecting the actuation of the microrobot. Finally, we discuss the future directions that would draw the basic outline for the next generation of mobile microrobots for in vitro applications.

Abstract

As a hyper-natural interaction technique in 3D user interfaces, non-isomorphic rotation has been considered an effective approach for rotation tasks, where a static or dynamic control-display gain can be applied to amplify or attenuate a rotation. However, it is not clear whether non-isomorphic rotation can benefit 6-degree-of-freedom (6-DOF) manipulation tasks in AR and VR. In this article, we extended the usability studies of non-isomorphic rotation from rotation-only tasks to 6-DOF manipulation tasks and analyzed the collected data using a 2-component model. Using a mixed reality (MR) simulation approach, we also investigated whether environment (AR or VR) had an impact on 3D manipulation tasks. The results reveal that although both static and dynamic non-isomorphic rotation techniques could save time and effort in ballistic phases, only dynamic non-isomorphic rotation was significantly faster than isomorphic rotation. Interestingly, while environment had no significant impact on overall user performance, we found evidence that it could affect fine-tuning in correction phases. We also found that most participants preferred AR over VR, indicating that environmental visual realism could be helpful to improve user experience.
