The advancement in virtual reality/augmented reality (VR/AR) has been achieved by breakthroughs in the realistic perception of virtual elements. Although VR/AR technology is advancing fast, enhanced sensor functions, long‐term wearability, and seamless integration with other electronic components are still required for more natural interactions with the virtual world. Here, this report reviews the recent advances in multifunctional wearable sensors and integrated functional devices for VR/AR applications. Specified device designs, packaging strategies, and interactive physiological sensors are summarized based on their methodological approaches for sensory inputs and virtual feedback. In addition, limitations of the existing systems, key challenges, and future directions are discussed. It is envisioned that this progress report's outcomes will expand the insights on wearable functional sensors and device interfaces toward next‐generation VR/AR technologies.
Augmented reality (AR) is a technology that integrates 3D virtual objects into the physical world in real-time, while virtual reality (VR) is a technology that immerses users in an interactive 3D virtual environment. The fast development of augmented reality (AR) and virtual reality (VR) technologies has reshaped how people interact with the physical world. This presentation will outline the results from two unique AR and one Web-based VR coastal engineering projects, motivating the next stage in the development of the augmented reality package for coastal students, engineers, and planners.

Wearable near-eye displays for virtual and augmented reality (VR/AR) have seen enormous growth in recent years. While researchers are exploiting a plethora of techniques to create life-like three-dimensional (3D) objects, there is a lack of awareness of the role of human perception in guiding the hardware development. An ultimate VR/AR headset must integrate the display, sensors, and processors in a compact enclosure that people can comfortably wear for a long time while allowing a superior immersion experience and user-friendly human–computer interaction. Compared with other 3D displays, the holographic display has unique advantages in providing natural depth cues and correcting eye aberrations. Therefore, it holds great promise to be the enabling technology for next-generation VR/AR devices. In this review, we survey the recent progress in holographic near-eye displays from the human-centric perspective.

In recent years, virtual/augmented reality (VR/AR) technology has received great attention due to its capability of creating various levels of immersive experiences. However, current wireless VR/AR devices are quite expensive, which hinders its large-scale deployment in practice. In this demo, we present a wireless interactive VR/AR teaching system based on popular Android phones. In such a demo, when a teacher explains a 3D model, multiple students can see it from exactly the same perspective as the teacher does through VR/AR glasses. When one student has a concern or question regarding a particular part of the 3D model, he/she can point it out, and a corresponding blue cursor will appear on screens of all users. Moreover, in the absence of 3D models in Android phones, we broadcast 3D models based on their visual priorities.more » « less

This poster presents the use of Augmented Reality (AR) and Virtual Reality (VR) to tackle 4 amongst the “14 Grand Challenges for Engineering in the 21st Century” identified by National Academy of Engineering. AR and VR are the technologies of the present and the future. AR creates a composite view by adding digital content to a real world view, often by using the camera of a smartphone and VR creates an immersive view where the user’s view is often cut off from the real world. The 14 challenges identify areas of science and technology that are achievable and sustainable to assist people and the planet to prosper. The 4 challenges tackled using AR/VR application in this poster are: Enhance virtual reality, Advance personalized learning, Provide access to clean water, and Make solar energy affordable. The solar system VR application is aimed at tackling two of the engineering challenges: (1) Enhance virtual reality and (2) Advance personalized learning. The VR application assists the user in visualizing and understanding our solar system by using a VR headset. It includes an immersive 360 degree view of our solar system where the user can use controllers to interact with celestial bodies-related information and to teleport to different points in the space to have a closer look at the planets and the Sun. The user has six degrees of freedom. The AR application for water tackles the engineering challenge: “Provide access to clean water”. The AR water application shows information on drinking water accessibility and the eco-friendly usage of bottles over plastic cups within the department buildings inside Auburn University. The user of the application has an augmented view of drinking water information on a smartphone. Every time the user points the smartphone camera towards a building, the application will render a composite view with drinking water information associated to the building. The Sun path visualization AR application tackles the engineering challenge: “Make solar energy affordable”. The application helps the user visualize sun path at a selected time and location. The sun path is augmented in the camera view of the device when the user points the camera towards the sky. The application provides information on sun altitude and azimuth. Also, it provides the user with sunrise and sunset data for a selected day. The information provided by the application can aid the user with effective solar panel placement. Using AR and VR technology to tackle these challenges enhances the user experience. The information from these applications are better curated and easily visualized, thus readily understandable by the end user. Therefore, usage of AR and VR technology to tackle these type of engineering challenges looks promising.more » « less

In a seminal article on augmented reality (AR) [7], Ron Azuma defines AR as a variation of virtual reality (VR), which completely immerses a user inside a synthetic environment. Azuma says “In contrast, AR allows the user to see the real world, with virtual objects superimposed upon or composited with the real world” [7] (emphasis added). Typically, a user wears a tracked stereoscopic head-mounted display (HMD) or holds a smartphone, showing the real world through optical or video means, with superimposed graphics that provide the appearance of virtual content that is related to and registered with the real world. While AR has been around since the 1960s [72], it is experiencing a renaissance of development and consumer interest. With exciting products from Microsoft (HoloLens), Metavision (Meta 2), and others; Apple’s AR Developer’s Kit (ARKit); and well-funded startups like Magic Leap [54], the future is looking even brighter, expecting that AR technologies will be absorbed into our daily lives and have a strong influence on our society in the foreseeable future.more » « less
