The Use of Smartglasses in Everyday Life University of Erfurt Faculty of Philosophy The Use of Smartglasses in Everyday Life A Grounded Theory Study Dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Dr. phil.) at the Faculty of Philosophy of the University of Erfurt submitted by Timothy Christoph Kessler from Munich November 2015 URN: urn:nbn:de:gbv:547-201600175 First Assessment: Prof. Dr. Joachim R. Höflich Second Assessment: Prof. Dr. Dr. Castulus Kolo Date of publication: 18th of April 2016 Abstract We live in a mobile world. Laptops, tablets and smartphones have never been as ubiquitous as they have been today. New technologies are invented on a daily basis, lead- ing to the altering of society on a macro level, and to the change of the everyday life on a micro level. Through the introduction of a new category of devices, wearable computers, we might experience a shift away from the traditional smartphone. This dissertation aims to examine the topic of smartglasses, especially Google Glass, and how these wearable devices are embedded into the everyday life and, consequently, into a society at large. The current research models which are concerned with mobile communication are only partly applicable due to the distinctive character of smartglasses. Furthermore, new legal and privacy challenges for smartglasses arise, which are not taken into account by ex- isting theories. Since the literature on smartglasses is close to non-existent, it is argued that new models need to be developed in order to fully understand the impact of smart- glasses on everyday life and society as a whole. This study thus aims to close this research gap by embarking on a qualitative journey which explores the application of smartglasses in the everyday life. The qualitative grounded theory methodology has been used in order to find themes and patterns to understand how a total of 41 participants used these kind of devices over a period of one week. In order to gain a holistic view of the proposed topic, the partici- pants had to wear the devices and were later interviewed about their experience. They were asked about topics such as the alteration of communication, privacy, reality percep- tion, human-computer interaction, the perception of others and alike. Furthermore, the participants were asked to fill out a quantitative media diary throughout their time with the device, which provided an additional set of data which could later be used to verify some of the interview statements. Based on these findings, a model has been proposed which specifically explains the sit- uational use of smartglasses and their respective key influencers. The main outcomes however confirm that the usage of smartglasses is vastly diverging from the use of the smartphone and is highly situational. Since the main use of smartglasses is in public places, privacy issues for the individual as well as for the immediate surroundings arise, mainly due to the head worn camera and the constant location tracking. Adding to the notion of a new need for sensitization, new methods of input such as voice and gesture commands alter the way the technology is interacted with and provide an additional layer of complexity.

  • Mutual Watching and Resistance to Mass Surveillance After Snowden
    Media and Communication (ISSN: 2183-2439) 2015, Volume 3, Issue 3, Pages 12-25 Doi: 10.17645/mac.v3i3.277 Article “Veillant Panoptic Assemblage”: Mutual Watching and Resistance to Mass Surveillance after Snowden Vian Bakir School of Creative Studies and Media, Bangor University, Bangor, LL57 2DG, UK; E-Mail: [email protected] Submitted: 9 April 2015 | In Revised Form: 16 July 2015 | Accepted: 4 August 2015 | Published: 20 October 2015 Abstract The Snowden leaks indicate the extent, nature, and means of contemporary mass digital surveillance of citizens by their intelligence agencies and the role of public oversight mechanisms in holding intelligence agencies to account. As such, they form a rich case study on the interactions of “veillance” (mutual watching) involving citizens, journalists, intelli- gence agencies and corporations. While Surveillance Studies, Intelligence Studies and Journalism Studies have little to say on surveillance of citizens’ data by intelligence agencies (and complicit surveillant corporations), they offer insights into the role of citizens and the press in holding power, and specifically the political-intelligence elite, to account. Atten- tion to such public oversight mechanisms facilitates critical interrogation of issues of surveillant power, resistance and intelligence accountability. It directs attention to the veillant panoptic assemblage (an arrangement of profoundly une- qual mutual watching, where citizens’ watching of self and others is, through corporate channels of data flow, fed back into state surveillance of citizens). Finally, it enables evaluation of post-Snowden steps taken towards achieving an equiveillant panoptic assemblage (where, alongside state and corporate surveillance of citizens, the intelligence-power elite, to ensure its accountability, faces robust scrutiny and action from wider civil society).

ABSTRACT Since the launch of Google Glass in 2014, smart glasses have mainly been designed to support micro-interactions. The ultimate goal for them to become an augmented reality interface has not yet been attained due to an encumbrance of controls. Augmented reality involves superimposing interactive computer graphics images onto physical objects in the real world. This survey reviews current research issues in the area of human-computer interaction for smart glasses. The survey first studies the smart glasses available in the market and afterwards investigates the interaction methods proposed in the wide body of literature. The interaction methods can be classified into hand-held, touch, and touchless input. This paper mainly focuses on the touch and touchless input. Touch input can be further divided into on-device and on-body, while touchless input can be classified into hands-free and freehand. Next, we summarize the existing research efforts and trends, in which touch and touchless input are evaluated by a total of eight interaction goals.

Abstract Background: Interest has been growing in the use of augmented reality (AR) based social communication interventions in autism spectrum disorders (ASD), yet little is known about their safety or negative effects, particularly in head-worn digital smartglasses. Research to understand the safety of smartglasses in people with ASD is crucial given that these individuals may have altered sensory sensitivity, impaired verbal and non-verbal communication, and may experience extreme distress in response to changes in routine or environment. Objective: The objective of this report was to assess the safety and negative effects of the Brain Power Autism System (BPAS), a novel AR smartglasses-based social communication aid for children and adults with ASD. BPAS uses emotion-based artificial intelligence and a smartglasses hardware platform that keeps users engaged in the social world by encouraging “heads-up” interaction, unlike tablet- or phone-based apps.

  • Are Wearables Good Or Bad for Society? an Exploration of Societal Benefits, Risks and Consequences of Augmented Reality Smart Glasses
    Are Wearables Good or Bad for Society? An Exploration of Societal Benefits, Risks and Consequences of Augmented Reality Smart Glasses. Daniel W.E. Hein, University of Bamberg Jennah Jodoin, University of Michigan-Dearborn Philipp A. Rauschnabel, University of Michigan-Dearborn Bjoern S. Ivens, University of Bamberg Abstract: Recent market research forecasts predict that a new form of wearable devices will soon influence the media landscape: Augmented Reality Smart Glasses. While prior research highlights numerous potentials in personal and professional settings of smart glasses, this technology has also triggered several controversies in public discussions, for example, the risk of violating privacy and copyright laws. Yet, little research addresses the questions of whether smart glasses are good or bad for societies, and if yes, why. This study conducts exploratory research to contribute to narrowing this gap. Based on a survey among consumers, we identify several societal benefits and risks that determine consumers’ evaluation of the anticipated and desired success of smart glasses. These findings lead to numerous important implications for consumers, scholars, managers, and policy makers. Introduction A recent study by Goldman Sachs (2016) asserts that Augmented reality (AR) smart glasses are the latest step in an evolution of digitization of reality and a large developing future market. What began with stationary computers that were temporarily online to receive and display information to their mostly business users in the last century turned into a network dominated by user-generated content (UGC), with users being mainly consumers that are permanently online and access the internet through a multitude of devices (Hennig-Thurau et al., 2010).

  • Factors Influencing Consumer Attitudes Towards M-Commerce AR Apps
    “I see myself, therefore I purchase”: factors influencing consumer attitudes towards m-commerce AR apps Mafalda Teles Roxo and Pedro Quelhas Brito Faculdade de Economia da Universidade do Porto and LIAAD-INESC TEC, Portugal [email protected]; [email protected] Abstract Mobile commerce (m-commerce) is starting to represent a significant share of e-commerce. The use of Augmented Reality (AR) by brands to convey information about their products - within the store and mainly as mobile apps – makes it possible for researchers and managers to understand consumer reactions. Although attitudes towards AR have been studied, the overall effect of distinct aspects such as the influence of others, the imagery, projection and perceived presence, has not been tackled as far as we know. Therefore, we conducted a study on 218 undergraduate students, using a pre-test post-test experimental design to address the following questions: (1) Do AR media characteristics affect consumer attitudes towards the medium in a mobile shopping context? Also, (2) Do the opinion and physical presence of people influence the attitude towards an m-commerce AR app? It found that AR characteristics such as projection and imagery positively influence attitudes towards m-commerce AR apps, whereas social variables did not have any influence. Keywords: MAR; m-commerce; consumer psychology; AR-consumer relationship. 1 Introduction Simultaneously with the increasing percentage of e-commerce sales resulting from mobile retail commerce (m-commerce), it is estimated that in the U.S., by 2020, 49.2% of online sales will be made using mobile apps (Statista, 2019b). Also, in 2018, approximately 57% of internet users purchased fashion-related products online (Statista, 2019a).

  • Light Engines for XR Smartglasses by Jonathan Waldern, Ph.D
    August 28, 2020 Light Engines for XR Smartglasses By Jonathan Waldern, Ph.D. The near-term obstacle to meeting an elegant form factor for Extended Reality1 (XR) glasses is the size of the light engine2 that projects an image into the waveguide, providing a daylight-bright, wide field-of-view mobile display For original equipment manufacturers (OEMs) developing XR smartglasses that employ diffractive wave- guide lenses, there are several light engine architectures contending for the throne. Highly transmissive daylight-bright glasses demanded by early adopting customers translate to a level of display efficiency, 2k-by-2k and up resolution plus high contrast, simply do not exist today in the required less than ~2cc (cubic centimeter) package size. This thought piece examines both Laser and LED contenders. It becomes clear that even if MicroLED (µLED) solutions do actually emerge as forecast in the next five years, fundamentally, diffractive wave- guides are not ideally paired to broadband LED illumination and so only laser based light engines, are the realistic option over the next 5+ years. Bottom Line Up Front • µLED, a new emissive panel technology causing considerable excitement in the XR community, does dispense with some bulky refractive illumination optics and beam splitters, but still re- quires a bulky projection lens. Yet an even greater fundamental problem of µLEDs is that while bright compared with OLED, the technology falls short of the maximum & focused brightness needed for diffractive and holographic waveguides due to the fundamental inefficiencies of LED divergence. • A laser diode (LD) based light engine has a pencil like beam of light which permits higher effi- ciency at a higher F#.

Several interventions scenarios, however, require the physical presence of a human operator: Augmented Reality (AR), together with a broad-band connection, represents a major opportunity to integrate diagnostic data with real-time in-situ acquisitions. Diagnostic information can be shared with remote specialists that are able to monitor and guide maintenance operations from a control room as if they were in place. Furthermore, integrating heterogeneous sensors with AR visualization displays could largely improve operators’ safety in complex and dangerous industrial plants. In this paper, we present a complete setup for a remote assistive maintenance intervention based on 5G networking and tested at a Vodafone Base Transceiver Station (BTS) within the Vodafone 5G Program. Technicians’ safety was improved by means of a lightweight AR Head-Mounted Display (HDM) equipped with a thermal camera and a depth sensor to foresee possible collisions with hot surfaces and dangerous objects, by leveraging the processing power of remote computing paired with the low latency of 5G connection.

  • Pointing Task on Smart Glasses: Comparison of Four Interaction Techniques
    Pointing task on smart glasses: Comparison of four interaction techniques Ilyasse Belkacema,, Isabelle Peccia, Benoît Martina aLCOMS, Universit´e de Lorraine, France Abstract Mobile devices such as smartphones, smartwatches or smart glasses have revolutionized how we interact. We are interested in smart glasses because they have the advantage of providing a simultaneous view of both physical and digital worlds. Despite this potential, pointing task on smart glasses is not really widespread. In this paper, we compared four interaction techniques for selecting targets : (a) the Absolute Head Movement and (b) the Relative Head Movement, where head movement controls the cursor on smart glasses in absolute or relative way, (c) the Absolute Free Hand interaction, where the forefinger control the cursor and (d) the Tactile Surface interaction, where the user controls the cursor via a small touchpad connected to smart glasses. We conducted an experiment with 18 participants. The Tactile Surface and Absolute Head Movement were the most efficient. The Relative Head Movement and Absolute Free Hand interactions were promising and require more exploration for other tasks. Keywords: Smart glasses, head movement interaction, free hand interaction, ISO 9241-411 1. Introduction Smart glasses are wearable devices that embed electronic components such as a display screen, an integrated processor, and sensors. They allow visualization and interaction with an interface that is displayed through the lens. Smart glasses provide users with a simul- taneous view of both physical and digital worlds. With a constant delivery of information close to the eyes, smart glasses provide a framework for many applications, including medical documentation, surgery, educational functions and gaming [1].

  • Veillance and Reciprocal Transparency: Surveillance Versus Sousveillance, AR Glass, Lifeglogging, and Wearable Computing
    Veillance and Reciprocal Transparency: Surveillance versus Sousveillance, AR Glass, Lifeglogging, and Wearable Computing Steve Mann SurvVeillanCeNTRETM, 330 Dundas Street West, Toronto, Ontario, Canada, M5T 1G5 Abstract—This paper explores the interplay between surveil- lance cameras (cameras affixed to large-entities such as buildings) and sousveillance cameras (cameras affixed to small entities such as individual people), laying contextual groundwork for the social implications of Augmented/Augmediated Reality, Digital Eye Glass, and the wearable camera as a vision and visual memory aid in everyday life. We now live in a society in which we have both “the few watching the many” (surveillance), AND “the many watching the few” (sousveillance). Widespread sousveillance will cause a transition from our one-sided surveillance society back to a situation akin to olden times when the sheriff could see what everyone was doing AND everyone could see what the sheriff was doing. We name this neutral form of watching “veillance” — from the French word “veiller” which means “to watch”. Veillance is a broad concept that includes both surveillance (oversight) and sousveillance (undersight), as well as dataveillance, uberveillance, etc.. Fig. 1. Many business establishments prohibit cameras, e.g.: “NO It follows that: (1) sousveillance (undersight) is necessary CELL PHONES”; “NO CAMERAS”; “NO CELL PHONE IN STORE to a healthy, fair, and balanced society whenever surveillance PLEASE!”; and “No video or photo taking”, while at the same time (oversight) is already being used; and (2) sousveillance has nu- requiring customers to bring and use cameras in order to read QR codes merous moral, ethical, socioeconomic, humanistic/humanitarian, for pre-purchase product information.
