This paper provides an overview of the findings from an evaluation of the role of Google Glass in education over the past three years. The authors have experimented with Optical Head Mounted Displays as a support tool for various learning activities over the past few years. The study described in the paper commenced back in 2014 and continued despite the fact that the development of the Google Glass technology was paused and then shifted towards enterprise clientele. This was a result of our confidence that the future of learning interfaces is aligned to the proliferation of augmented reality and the fact that the Google Glass interface offers an ideal tool for learners due to its light structure and seamless wearing experience. The paper discusses how Google Glass has been used for a range of learning activities and describes the learners' experiences from using the device. The main contribution of the paper is in the form of measuring the success of the specific interface by sharing the results of three years of evaluations. The evaluation results are further analysed taking under consideration a number of profiling techniques of the learners involved including their personality type and learning style.

Applying procedural knowledge is important in situations in which manual working tasks need to be executed. Exemplary activities exist in many enterprises (e.g. repairing machines) as well as in private life (e.g. do-it-yourself activities). However, procedural knowledge for manual working tasks is difficult to train using common learning tools like paper-based manuals or e-learning modules as learners are often not able to apply the learning content at the same time while learning. A possibility to improve the training is to provide learning content in situated learning contexts hands-free. One emerging technology that is able to do this is wearable computing (e.g. smart glasses). Thus, the main objective of this paper is to determine how a smart-glasses-based learning system can support learners to train manual working tasks. Therefore, we present the LearningGlasses App, which provides step-by-step guidance through working processes by displaying learning content in situated learning contexts via the head-mounted display of Google Glass. In this way, learners have the possibility to execute a working process simultaneously while it is displayed in their field of vision. To develop the learning system, we followed the design science research approach. Consequently, we started our research with a real-world problem, which we derived in a previous study using a literature review and expert interviews. Based on this, we present the subsequent design, implementation and evaluation phase of the LearningGlasses App in this paper: After designing the application, we implemented it as a proof-of-concept for Google Glass. Finally, we evaluated the application in a laboratory experiment. Using this methodology, we are able to provide design recommendations for smart-glasses-based learning systems for training procedural knowledge. The results of our research can contribute to both, research and practice: First, it contributes to the research knowledge base, as it may be used as starting point for further research projects (e.g. regarding technical or didactical aspects). Second, practitioners get insights about how to provide learners with the possibility to train manual working tasks using smart glasses in situated learning contexts. Furthermore, they can use the outlined design recommendations to implement learning applications for smart glasses in practice. [ABSTRACT FROM AUTHOR]

In this paper a new way of simplifying automotive maintenance tasks is proposed. It uses state of the art augmented reality (AR) for 3D tracking, optical character recognition (OCR) for identifying the types and models of cars, and virtual reality (VR) for the visualization of damages for service technicians. Also, special hardware capabilities like the motion sensors of the Google Glass product are applied, supporting hands-free operation on this head-mounted device. An application has been created which gives the service technician all the information needed without technology interfering with the actual work of repairing a vehicle. Also, the amount of paper flow during the maintenance process is reduced. Based on design science principles the suitability of the created artifacts for the defined application field is evaluated.

The dissemination of 3D-enabled devices like 3D displays in entertainment environments, smart mobile devices or head mounted systems like Google Glass or Oculus Rift is rapidly growing. Regarding learning scenarios the use of 3D-enhanced applications is rare. As the perception of depth in a three-dimensional model is often necessary to understand the principles of operations there is a sufficient potential for the medical sector to evaluate 3D-enhanced courses. In our study we evaluated the complexity and effort one needs to create and integrate 3D models in learning management systems and the learning outcome. This paper describes our approach to use 3D interactive tooth-models for teaching orthodontists in the context of measures to correct tooth positions. Therefore several chronological 3d models and morphing animations were used to explain the measures and their impact. To create 3d models different methods where tested. Some methods like laser scanning are very accurate but are unable to produce textures, others are photorealistic, but the 3d mesh is imprecise. Furthermore there are big differences in scanning time and the ability of scanning shiny surfaces. In our case especially the use of orthophotographic methods with mobile devices and cloud services to build models was successful. This case study presents a best practice solution for the creation and implementation of these models in an eLearning course, which was integrated in the LMS moodle to study the potential of this approach. Some effort of future work is still necessary in order to enhance and transfer this concept to other scenarios and to evaluate the outcome of 3D-enhanced learning cou1/4 [ABSTRACT FROM AUTHOR]

The ubiquity of cameras in today's world has played a key role in the growth of sensing technology and mobile computing. However, on the other hand, it has also raised serious concerns about privacy of people who are photographed, intentionally or unintentionally. The popularity of publishing pictures in social networks adds to the concern that the photographed user has the least control over his/her picture. In this paper, we present the design, implementation and evaluation of "invisible light beacons" where privacy preferences of photographed users are communicated to photographing cameras. Particularly, we explore a design where the beacon transmitters are worn by users on their eye-wear and transmit a privacy code through ON-OFF patterns of light beams from IR LEDs. The beacons are received and decoded by a camera and mapped to different privacy preferences corresponding to that code. Based on the experimental evaluation of thousands of data points using our prototype implementation we show that the detection accuracy of a known privacy code is greater than 98%, and error rate of communicating a random stream of bits over an indoor IR-camera channel is within 7% at packet level and of the order of 10-3 at bit level.

This paper details an authentication mechanism aimed to aid individuals with visual impairments in accessing online accounts on desktop computers, and decrease the security threat of observers, or shoulder surfer, by providing an alternative to entering typical alphanumeric passwords on keyboards. The mechanism uses a head-mounted wearable device, Google Glass, because it provides feedback directly to the wearer obscuring it from observers, and it—s easy-to-locate and interact with gesture pad, which accepts input from the user. The mechanism is in preparation to enter the testing phase with individuals of the targeted demographic. [ABSTRACT FROM AUTHOR]

A variety of tasks with robots require directing the robot to interact with objects or locations in the world. While many interfaces currently exist for such interactions, in this paper, we focus on inputs which can be categorized as pointing. Specifically, we look at two ways of using the head as a pointing input: Google Glass, and a head pose estimation technique which uses RGBD data. While both of these input modalities have their own advantages and disadvantages, we evaluate them simply as pointing devices, looking at how the device characteristics affects pointing performance. This is evaluated in a user study in which participants perform a series of object designation tasks. We then use distance, time, and object size data to evaluate input devices using Fitts' Law.

In this paper we present a wearable prototype that can automatically recognize affective cues such as number of people present, their age and gender distributions given an image. We customize the prototype in the context of helping people with visual impairments to better navigate social scenarios. Running an experiment to validate this technology in social scenarios remains part of our future work. [ABSTRACT FROM AUTHOR]

Head-mounted displays such as Google Glass offer potential advantages for persons with motor impairments (MI). For example, they are always available and offer relatively hands-free interaction compared to a mobile phone. Despite this potential, there is little prior work examining the accessibility of such devices. In this poster paper, we perform a preliminary assessment of the accessibility of Google Glass for users with MI and the potential impacts of a head-mounted interactive computer. Our findings show that, while the touchpad is particularly difficult to use-impossible for three participants-advantages over a phone include that it is relatively hands free, does not require looking down at the display, and cannot be easily dropped.

Assistive technology solutions can help people with disability from social isolation, depression, facilitate social interaction and enhance the quality of life. Limited access to non-verbal cues hinders the social interaction of people who are blind or visually impaired. This paper presents 'Expression' - an integrated assistive solution using Google Glass. The key function of the system is to enable the user to perceive social signals during a natural face-to-face conversation. Subjective evaluation of Expression was performed using a five (5) point Likert Scale and was found to be excellent(4:383). [ABSTRACT FROM AUTHOR]

Google Glass has been a promise of a first wearable computing device to be sold in a large scale. When it was launched, some experts claimed that Google Glass represented the future of computing, while other actors, such as journalists, lawmakers, artists and NGOs raised a set of concerns about how this device will be incorporated in our daily lives, for instance, regarding privacy issues. Therefore, we have an interesting controversy (a shared uncertainty) about wearable computing. The aim of this paper is to explore the controversy that arose with the launch of Google Glass in order to understand what are the views and expectations about wearable-ubiquitous computing manifested by the different actors involved. Our main theoretical foundation is the Actor Network Theory. The research method was inductive and based on the collection and analysis of secondary data from the Web, following the method of controversy mapping. As research results, we map and analyze the different expectations (hopes and fears) about Glass, from the many different human actors involved in the controversy, such as developers, lawmakers, IT experts, consultants, artists and ?ordinary people?, among others. The role played by the non-human actors, such as smartphones, operational systems and clothing is also addressed. By understanding this controversy, we raise a set of issues and implications for the future development of wearable and ubiquitous computing. [ABSTRACT FROM AUTHOR]
