Digital impressions of teeth, obtained through intra-oral scanning, allow for more efficient and cost effective treatments of many dental indications. Current state-of-the-art intra-oral impression acquisition systems make use of a separate monitor to show the scanning progress, forcing the dentist to divert attention away from the scanner and the patient. In this paper, we present an augmented reality...
The state of the art VR/AR devices provide access to completely virtual environments or augment information on the existing world seen by the user. Wearable devices encumber the users, and sometimes even cut them off completely from the real world. Users interact with digital avatars instead of the real people themselves. Spatially augmented reality (SAR) instead focuses on illuminating physical spaces...
This paper presents an alternative navigation tool that can be used in indoor environment. This is due to restrictions on GPS signals that cannot be detected in indoor locations. The work presented here shows the development of an interactive indoor localization system that uses live input video capture and can identify location markers to indicate its current location. In addition, augmented reality...
Museum visitors need support tools to facilitate their informal learning. In this paper, we present ARCoins, an augmented reality app to support informal learning about numismatics. Our app helps museum visitors to read the deteriorated text of coins and also shows additional information that offers a clear idea of the general meaning of the coinage of the coins. The app recognizes the real coins...
Peripheral vision loss (also called tunnel vision) is one of the main visual field disorders that can be very frustrating, and affect confidence and main activities of the patient. In this paper, two promising solutions for the peripheral vision loss are presented and discussed. The first one uses optical see-through glasses that are augmented by computer-generated images to notify the user about...
We demonstrate “Blurry (Sticky) Finger” in which one uses the unfocused blurred finger, sense of proprioception, to aim, point and directly select a distant object in the real world with both eyes open. We showcase two demo applications. The first illustrates the accuracy and usability of the proposed method with the target objects lying at a fixed depth on a monitor. The second is an AR based object...
Common spatial augmented reality techniques use video projection to superimpose virtual information over a physical scene. As the augmentation happens directly in the real world, multiple users can see the augmented scene, however, the augmentation is the same for all users. We introduce EgoSAR, a new approach that makes it possible to have a personalized, view-dependent augmentation, in multi-user...
The recent developments in technology have led to new emerging wearable devices such as Smart Glasses. Usually, consumer electronics devices are designed for the benefits and functionalities they can provide, and the security aspect is incorporated later. In its core, a Smart Glass is based on components available in modern smartphones. This includes the CPU, Sensors and Operating System. Thus would...
Augmented Reality (AR) applications are nowadays largely diffused in many fields of use, especially for entertainment, and the market of AR applications for mobile devices grows faster and faster. Moreover, new and innovative hardware for human-computer interaction has been deployed, such as the Leap Motion Controller. This paper presents some preliminary results in the design and development of a...
Nyctalopia, millions of people all over the world suffering from which, brings much trouble to the patients. The available night vision systems are poor in user experience but cost much. In this paper we design and implement an Augmented-Reality night vision enhancement application for see-through glasses. According to our model proposed for the night blindness, fast and efficient algorithms are used...
This paper discusses a technology that is expected to widely spread in the near future, which is the Sixth Sense Technology. With this new technology yet to be introduced in the market, different implementation approaches are discussed. Such approaches are demonstrated through other inventions similar to the Sixth Sense (SS). They all fall into the same category, which is Augmented Reality Technologies...
Augmented Reality devices are about to reach mainstream markets but applications have to meet user expectations in terms of usage and ergonomics. In this paper, we present a reallife outdoor AR application for marine navigation assistance that alleviates cognitive load issues (orientation between electronic navigational devices and bridge view) for vessels and recreational boats. First, we describe...
Google glass is a hands-free, head-mounted intelligent device that can be worn as a wearable computing eyewear. This work discusses its potential in education by proposing an application, the Glassist, aiming at helping teachers management tasks. The application allows teachers to create individual portfolios for students, manage their information and share it with peers. The tool uses Augmented Reality...
Cutting-edge work on 3D telepresence at a multinational research center provides insight into the technology's potential, as well as into its remaining challenges. The first Web extra at http://youtu.be/r4SqJdXkOjQ is a video describing FreeCam, a system capable of generating live free-viewpoint video by simulating the output of a virtual camera moving through a dynamic scene. The second Web extra...
This paper presents “FreeGlass”, a hands-free user-buildable wearable computer system based on Mann's “Digital Eye Glass” (also known as EyeTap) concept developed 35 years ago. Like Mann's “Eye Glass”, FreeGlass is based on free and Open Source principles consistent with a free and open i-Society. FreeGlass is suitable for researchers and creators of AR (Augmediated Reality) Glass, LifeGlogging, etc...
We present an augmented reality magic mirror for teaching anatomy. The system uses a depth camera to track the pose of a user standing in front of a large display. A volume visualization of a CT dataset is augmented onto the user, creating the illusion that the user can look into his body. Using gestures, different slices from the CT and a photographic dataset can be selected for visualization. In...
This paper presents an approach that can relight captured image with real incident light source. We first captured basis images of objects illuminated with a projector as the basis light source. We then established a pixel level mapping relationship between a real incident light source and the basis light source. Finally we developed a relighting algorithm that can simulate the relit effects with...
