“…A slight "wiggle" of the virtual camera produces a parallax motion that gives the artist a better understanding of the virtual scene. This finding is in accordance with our previous findings [2], in which 3D artists reported in a survey that they used the camera controls of their 3D software extensively or even constantly.…”

“…The input device was either a normal 2D mouse or a 3D pinch glove. The mouse was a wired laser mouse (a Dell MOC5UO), which is the most common input device in 3D design work [2]. When the mouse was used, a 2D cursor was displayed in the dominant-eye view only and thus was parallax free (similar to looking through a red-dot sight or reflector sight of a rifle).…”

“…In our previous research we analyzed the real-life work situation of 3D media professionals showed that 3D UIs or even 3D input devices have so far failed to appeal to designers for adoption in their daily work [2]. This may be related to a lack of understanding of specific UI design factors relative to the requirements of this field of work.…”

With the ongoing introduction of wide-FOV VR head-worn displays into the consumer market, the application of VR 3D UIs to professional work environments is attracting increasing attention. One of the most conspicuous concepts is immersive 3D modeling and content creation. In spite of the long research history and multitude of proposed systems, there have been very few analyses of the effect of 3D UIs on productivity in 3D design.In this work, we explore the effect of positional head-tracking and its accompanying parallax depth cues on task performance in 3D object selection and transformation in a setting modeled after 3D design work. Previous studies have come to different conclusions on the importance of positional head-tracking and did not investigate professional 3D modeling tools. In contrast, we performed a user study with design students using professional software on a task that closely emulates their work. Surprisingly, we did not find a significant effect of positional head-tracking on task-completion time, neither when using a traditional 2D mouse nor when using a pinch glove as a 3D input device. Furthermore, we found that the users worked significantly faster with the mouse. We discuss possible explanations and implications for the design of 3D UIs.

“…A separate issue affecting the authoring of AR experiences is represented by the scarce availability of 3D content, which is often expensive and time-consuming to create [27]. Dedicated 3D modeling and animation tools have been created for this purpose, and some solutions even include the creation of content inside AR/VR [6,22,43], but their discussion is outside the scope of this paper.…”

Figure 1: CAVE-AR is a virtual reality (VR) authoring tool aimed at assisting designers in creating, simulating and debugging augmented reality (AR) experiences. In the left image, a user in the real world is seeing AR content through his mobile device. On the right, a second user is able to monitor in real-time, through our authoring system, what the real-world user is seeing, and debug eventual faults. A dedicated panel displays hardware information about the user's mobile device (a), whose horizontal positioning accuracy is represented by a red circle (b). Two additional views display the estimated perspective of the user (c) and the live AR video feed from the device camera (d). ABSTRACTDespite advances in augmented reality (AR), the process of creating meaningful experiences with this technology is still extremely challenging. Due to different tracking implementations and hardware constraints, developing AR applications either requires low-level programming skills, or is done through specific authoring tools that largely sacrifice the possibility of customizing the AR experience. Existing development workflows also do not support previewing or simulating the AR experience, requiring a lengthy process of trial and error by which content creators deploy and physically test applications in each iteration. To mitigate these limitations, we propose CAVE-AR, a novel virtual reality system for authoring, simulating and debugging custom augmented reality experiences. Available both as a standalone or a plug-in tool, CAVE-AR is based on the concept of representing in the same global reference system both in AR content and tracking information, mixing geographical information, architectural features, and sensor data to simulate the context of an AR experience. Thanks to its novel abstraction of existing tracking technologies, CAVE-AR operates independently of users' devices, and integrates with existing programming tools to provide maximum flexibility. Our VR application provides designers with ways to create and modify an AR application, even while others are in the midst of using it. CAVE-AR further allows the designer to track how users are behav-*

“…Compared with traditional devices, more flexible interaction methods and tools have been developed in some computer-vision based AR systems. Visiontracked fiducial markers have been used for realizing interactions between users and SOs [14,15]. A handheld device-based interaction tool has been proposed for twodimensional (2D) to three-dimensional (3D) AR modeling [16].…”

3D bare-hand interactions enabling ubiquitous interactions with smart objects

Ubiquitous augmented reality (UAR) implementation can benefit smart shop floor operations significantly. UAR from a user's first-person view can support and provide the user with suitable and comprehensive information without him/her being distracted from ongoing tasks. A natural hand-based interaction interface, namely, a mobile bare-hand interface (MBHI), is proposed to assist a user in exploring and navigating a large amount of information for a task in the user's first-person view. The integration of a smart shop floor and UAR-based MBHI is particularly challenging. A real shop floor environment is composed of challenging conditions for the implementation of UAR, e.g., messy backgrounds and significant changes in illumination conditions. Meanwhile, the MBHI is required to provide precise and quick responses to minimize the difficulty of a user's task. In this study, a wearable UAR system integrated with an MBHI is proposed to augment the shop floor environment with smart information. A case study is implemented to demonstrate the practicality and effectiveness of the proposed UAR and MBHI system.
