Usable is not enough: towards of human-centred, positive and inclusive security

Prof. Dr. Angela Sasse, Tuesday, Feb. 1st, 1700 CET 

Bio: Dr. Angela Sasse is a computer scientist whose research spans the areas of human-computer interaction and computer security. She is Horst Görtz Endowed Professor of Human-Centred Security at Ruhr University Bochum and has a part-time position as Professor of Human-Centred Technology at University College London. Angela will conduct a conversation titled “Usable is not enough: towards human-centred positive and inclusive security.

Abstract Usable security as a research area can be traced back to 1999, the year when the seminal papers “Why Johnny Can’t Encrypt” and “Users are not the Enemy” were published. But in the practitioner discourse, humans are still portrayed as the “weakest link”, and much of the research effort has focused on “fixing” people through education and persuasion, or motivating them through fear. Human-centred security is changing the focus: paying more attention to marginalised user groups, giving users more agency, and engaging them in the design process. As important as good design is to foster the development of secure habits that work across contexts and empower users, rather than leaving them scared and helpless.

Real-Time Eye Tracking: Applications, Analytics, Implementation

Andrew Duchowski, Tuesday, Nov. 16th, 1700 CET

Bio: Dr. Duchowski is a professor of Computer Science at Clemson University. He received his baccalaureate (1990) from Simon Fraser University, Canada, and doctorate (1997) from Texas A&M University, USA, both in Computer Science. His research and teaching interests include visual attention and perception, computer vision, and computer graphics. He is a noted research leader in the field of eye tracking, having produced a corpus of related papers and a monograph on eye tracking methodology, and has delivered courses and seminars on the subject at international conferences. He maintains the eyeCU, Clemson’s eye tracking laboratory and teaches a regular course on eye tracking methodology attracting students from various disciplines across campus.

Abstract: Starting with an overview of eye-tracking applications, interactive applications are reviewed: assistive (gaze-responsive), active (selection, look to shoot), passive (foveated rendering, a.k.a. gaze-contingent displays), and expressive (gaze synthesis). These applications expose the need for advanced real-time eye movement processing beyond the current state-of-the-art. Offline event detection via velocity-based filtering or position-variance approaches seem inadequate in online settings. Suggestions are made regarding possible approaches to event detection, ambient/focal attention modeling, smooth pursuit tracking and interaction, and real-time pupillometric measures, e.g., of cognitive load. Interactive Python demonstrations will be given of potential real-time approaches to illustrate present limitations and directions for future development.

“My Work In Gesture: Design, Recognition & Open Questions“

Jacob Wobbrock, Tuesday, Nov. 9th, 1700 CET

Bio: Jacob Wobbrock is a Professor of human-computer interaction (HCI) in The Information School and, by courtesy, in the Paul G. Allen School of Computer Science & Engineering at the University of Washington, where he directs the ACE Lab and co-directs the CREATE Center. He is also a founding member of the DUB Group and the MHCI+D degree. His Ph.D. students come from information science and computer science.

His research seeks to scientifically understand people’s experiences of computers and information, and to improve those experiences by inventing and evaluating new interactive technologies, especially for people with disabilities. His specific research topics include input and interaction techniques, human performance measurement and modeling, HCI research and design methods, mobile computing, and accessible computing.

Gaze for Interaction with Ubiquitous Computing Systems: Basics, Foundations, Advances, and Challenges.

Enkelejda Kasneci and Hans Gellersen, Tuesday, Nov. 2nd, 1700 CET

Bio: Enkelejda Kasneci is a full professor of Computer Science at the University of Tübingen, Germany, where she leads the Human-Computer Interaction Group. As a BOSCH-scholar, she received her M.Sc. degree in Computer Science from the University of Stuttgart in 2007. In 2013, she received her PhD in Computer Science from the University of Tübingen. For her PhD research, she was awarded the research prize of the Federation Südwestmetall in 2014. From 2013 to 2015, she was a Margarete-von-Wrangell Fellow. Her main research interests are applied machine learning, eye-tracking technology and applications. She is a reviewer and PC member for several journals and major conferences. In 2016, she founded LeadersLikeHer, the world’s first open career network for women from industrial, research and public organizations.

Bio: Hans Gellersen is a full professor in the department of computing and communications at Lancaster University. His interest is in HCI, human interface technology, and the design of novel sensing and interaction techniques for anything from smart devices to AR/VR. In particularly he interested in eye movement and recently won an ERC Advanced Grant to investigate new foundations in for gaze and gestural interaction. Over the last ten years, his group has contributed major innovations on gaze in HCI, notably smooth pursuit interfaces and techniques, gaze-supported manual input, and eye-head interaction. Recently he also investigated interaction in 3D but he maintains long-standing interests in ubiquitous computing, cross-device interaction and interfaces that blend the digital and the virtual.

Digital Touch: Somatic Symbiosis, Correspondence, Alterity, or Monster

Kristina Höök, Tuesday, Oct. 26th, 1700 CEST

Bio: Kristina Höök is a professor in Interaction Design at
KTH Royal Institute of Technology in Stockholm (and used to be the director of the Mobile Life centre).  Her research interests include affective interaction, somaesthetic design, internet of things and anything that makes life with technology more meaningful, enjoyable, creative and aesthetically appealing. 

Abstract: 
Three recent technical and societal developments are challenging the existing ideals of interaction design, namely the move towards hybrid physical/digital materials, the emergence of an increasingly complex and fluid digital ecology, and the increasing proportion of autonomous or partially autonomous systems changing their behavior over time and with use. These challenges in turn motivate us to propose three directions in which new ideals for interaction design might be sought: the first is to go beyond the language-body divide that implicitly frames most of our current understandings of experience and meaning, the second is to extend the scope of interaction design from individual interfaces to the complex socio-technical fabric of human and nonhuman actors, and the third is to go beyond predictability by learning to design with machine learning. This had lead to a rise of novel theoretical positions on how to define our relationship to smart objects, autonomous technologies, infrastructures or wearables. Theories such as postphenomenological, pragmatist, somaesthetics, feminist and sociological theories propose other engagements, other ways of interacting, sometimes decentring the “human”, sometimes enriching or questioning what can be understood as the category “human”. The postphenomenological position is that embodiment is but one of the possible interactions: engaging with an alterity or entering into a hermeneutic relationship could be other ways of framing our interactions with technology. In somaesthetics and different feminist theories, pluralist, soma-grounded understanding of the human condition leads to richer, complex somasensory entanglements with technologies.  Theories of correspondence helps us shift beyond the idea of dialogue or interaction. Sometimes, the experience is best framed as in the humanities: as a monster.
