SACHI Seminar – Professor Alan Dix: Sufficient Reason


Event details

  • When: 16th October 2018 14:00 - 15:00
  • Where: Cole 1.33a

Title:  Sufficient Reason

Abstract:  A job candidate has been pre-selected for shortlist by a neural net; an autonomous car has suddenly changed lanes almost causing an accident; the intelligent fridge has ordered an extra pint of milk.  From the life changing or life threatening to day-to-day living, decisions are made by computer systems on our behalf.  If something goes wrong, or even when the decision appears correct, we may need to ask the question, “why?”  In the case of failures we need to know whether it is the result of a bug in the software,; a need for more data, sensors or training; or simply one of those things: a decision correct in the context, that happened to turn out badly.  Even if the decision appears acceptable, we may wish to understand it for our own curiosity, peace of mind, or for legal compliance.  In this talk I will pick up threads of research dating back to early work in the 1990s on gender and ethnic bias in black-box machine-learning systems, as well as more recent developments such as deep learning and concerns such as those that gave rise to the EPSRC human-like computing programme.  In particular I will present nascent work on an AIX Toolkit (AI explainability): a structured collection of techniques designed to help developers of intelligent systems create more comprehensible representations of the reasoning.  Crucial to the AIX Toolkit is the understanding that human-human explanations are rarely utterly precise or reproducible, but they are sufficient to inspire confidence and trust in a collaborative endeavour.

Speaker biography:  Alan Dix is Director of the Computational Foundry at Swansea University.  Previously he has spent 10 years in a mix of academic and commercial roles, most recently as Professor in the HCI Centre at the University of Birmingham and Senior Researcher at Talis. He has worked in human–computer interaction research since the mid 1980s, and is the author of one of the major international textbooks on HCI as well as of over 450 research publications from formal methods to design creativity, including some of the earliest papers in the HCI literature on topics such as privacy, mobile interaction, and gender and ethnic bias in intelligent algorithms.   Issues of space and time in user interaction have been a long term interest, from his “Myth of the Infinitely Fast Machine” in 1987, to his co-authored book, TouchIT, on physicality in a digital age, due to be published in 2018. Alan organises a twice-yearly workshop, Tiree Tech Wave, on the small Scottish island where he has lived for 10 years, and where he has been engaged in a number of community research projects relating to heritage, communications, energy use and open data.  In 2013, he walked the complete periphery of Wales, over a thousand miles.  This was a personal journey, but also a research expedition, exploring the technology needs of the walker and the people along the way.   The data from this including 19,000 images, about 150,000 words of geo-tagged text, and many giga-bytes of bio-data is available in the public domain as an ‘open science’ resource. Alan’s new role at the Computational Foundry has brought him back to his homeland.  The Computational Foundry is a 30 million pound initiative to boost computational research in Wales with a strong focus on creating social and economic benefit.  Digital technology is at a bifurcation point when it could simply reinforce existing structures of industry, government and health, or could allow us to radically reimagine and transform society.  The Foundry is built on the belief that addressing human needs and human values requires and inspires the deepest forms of fundamental science.  http://alandix.com/

SACHI Seminar – Alyssa Goodman: Visualization and the Universe


Event details

  • When: 12th October 2018 12:00 - 13:00
  • Where: Cole 1.33b

Title:  

Visualization and the Universe: How and why astronomers, doctors, and you need to work together to understand the world around us

 

Abstract:

Astronomy has long been a field reliant on visualization. First, it was literal visualization—looking at the Sky. Today, though, astronomers are faced with the daunting task of understanding gigantic digital images from across the electromagnetic spectrum and contextualizing them with hugely complex physics simulations, in order to make more sense of our Universe.   In this talk, I will explain how new approaches to simultaneously exploring and explaining vast data sets allow astronomers—and other scientists—to make sense of what the data have to say, and to communicate what they learn to each other, and to the public.  In particular, I will talk about the evolution of the multi-dimensional linked-view data visualization environment known as glue (glueviz.org) and the Universe Information System called WorldWide Telescope (worldwidetelescope.org).  I will explain how glue is being used in medical and geographic information sciences, and I will discuss its future potential to expand into all fields where diverse, but related, multi-dimensional data sets can be profitably analyzed together.  Toward the aim of bringing the insights to be discussed to a broader audience, I will also introduce the new “10 Questions to Ask When Creating a Visualization” website, 10QViz.org.

SACHI Seminar: Alessio Malizia – User Experience: a step towards Natural User Interfaces.


Event details

  • When: 7th June 2018 14:00 - 15:00
  • Where: Cole 1.33a

Title: User Experience: a step towards Natural User Interfaces.

Abstract: The road to natural interfaces is still long and we are now witnessing an artificial naturality. These interfaces are natural, in the sense they employ hand gestures, but they are also artificial, because the system designer imposes the set of gestures. In this lecture we will explore together the benefits and issues of Natural User Interfaces.

Speaker biography: Alessio Malizia is a Professor of UX Design at the University of Hertfordshire and a distinguished speaker of the ACM (the international Association for Computer Machinery); he lives in London but is a “global soul” and has been living in Italy, Spain and US. He is the son of a blacksmith, but thereafter all pretensions of manual skills end. Prof. Malizia began his career as a bearded computer scientist at Sapienza – University of Rome and then, after an industrial experience in IBM and Silicon Graphics, moved on with a career in research. He was visiting researcher at the Xerox PARC where he was appreciated for his skills in neural networks (Multilayer Perceptrons) and as peanut butter and chocolate biscuits eater. He worked as Senior Lecturer at Brunel University London and as Associate Professor (and Spanish tapas aficionado) at the University Carlos III of Madrid. Prof Malizia’s research and teaching interests focus on Human-Centred Systems.

He is interested in the design of Ubiquitous Interactive Systems with a special focus on the End-User Development community. He is particularly interested in systems where the physical and digital become seamlessly intertwined producing a new hybrid landscape and the study of problems arising from designing such complex hybrid environments involving collaboration of various disciplines and stakeholders. In his role at the School of Creative Arts at University of Hertfordshire, he is keen to develop novel approaches and attract funding for improving methods to design almost invisible interfaces embedded in a physical environment naturally exploited by users’ innate interaction modalities.

SACHI Seminar: Matjaž Kljun – Large scale studies of habit changing interface design


Event details

  • When: 12th April 2018 14:00 - 15:00
  • Where: Cole 1.33b

SACHI Seminar – Large scale studies of habit changing interface design

Speaker: Matjaž Kljun

Abstract:

Various technologies can be used in persuading people to change their habits, behaviours or attitudes. Such technologies are defined as persuasive and they are used in a variety of fields such as marketing, public health and education.

We are daily exposed to persuasion through different visualizations and triggers on all our devices. For example, a social networking application tries to persuade us in opening the app with a push notification and once the app is opened other hooks are placed so we spend more time in it. However, such applications are usually installed by us and we are inclined in using them. But could we persuade highly busy professionals in completing a training course or just about everybody to read terms of service? We will discuss these issues through large-scale studies that have been in done in the wild.

Speaker biography: Matjaž Kljun is an assistant professor at the Faculty of Mathematics, Natural Sciences and Information Technologies at University of Primorska and is co-directing the HICUP lab (Humans Interacting with Computers at University of Primorska) and a research associate at the Faculty of Information studies, Slovenia. He received his Ph.D. degree in computer science from Lancaster University, UK. His research interests span across various fields related to Human-Computer Interaction, Personal Information Management and the use of technologies in teaching and learning.

SACHI Seminar: Klen Čopič Pucihar – The Missing Interface: Micro Gestures on Objects for Augmented Reality Interaction

  • When: 12th April 2018 14:00 - 15:00
  • Where: Cole 1.33b

SACHI Seminar – The Missing Interface: Micro Gestures on Objects for Augmented Reality Interaction

Speaker: Klen Čopič Pucihar

Abstract:

Augmented reality technology can introduce digital elements to arbitrary objects. However, these objects were never designed to incorporate the digital component, hence do not provide the necessary interface. To overcome this limitation, AR Interaction systems add sensors to objects, use additional handheld hardware or perform hand and body tracking. These methods are not optimal for direct interaction with physical objects  because they:

  • require modification of existing objects,
  • require the the user to hold the controller in their hand,
  • are based on synthesis of captured RGB or RGB-D data streams imposing the following limitations: (i) gestures need to be  performed within the view of the camera; (ii) the gestures include reasonable large hand or finger movements (e.g. pinching the fingers, blooming gesture of opening the palm; (iii) the hand performing gesture is not occluded (e.g. cannot detect gestures if performed whilst grasping an object).

In this talk Klen will look at alternative methods which try to overcome such limitations and make inconspicuous, precise and flexible object oriented interaction possible for both augmented and mediated reality applications.

Speaker Biography

Klen Čopič Pucihar is assistant professor at the Faculty of Mathematics, Natural Sciences and Information Technologies at University of Primorska. Klen’s research vision is to look for new ways in which one could augmented, modify and mediate rich sources of visual, auditory and tactile stimuli that fabricate our everyday life experiences. The goal is to augment human abilities with new ways of using computational resources. This is important because the interface presents itself as the bottleneck between us humans and the benefit ever increasing computational resources could have on our everyday life. This makes the interfaces the core challenge for the future and the essence of Klen’s research which is currently mainly concentrated on augmented reality, mobile computing and human-computer interaction focusing on different perceptual issues that arise whilst interacting with various computer systems which lead to innovative user interface designs. Klen’s work was published as high ranked scientific publications and won him best poster award at ISMAR 2014.

SACHI Seminar – Florian Echtler (Bauhaus-Universität Weimar): Instant Interaction


Event details

  • When: 16th November 2017 15:00 - 16:00
  • Where: Cole 1.33b

Title:

Instant Interaction

Abstract:

Although Mark Weiser’s original vision of “ubiquitous computing” has all but arrived due to the wide availability of smartphones, tablets and interactive screens, the envisioned ease of use is still mostly lacking. This is particularly apparent when we consider interaction and collaboration between multiple persons and their personal mobile devices. These issues can be partly mitigated by relying on cloud services for data exchange, but this approach opens up multiple other issues regarding data safety and privacy. In this talk, I will present the concept of “instant interaction”, which aims to enable ad-hoc interaction between multiple persons, their individual mobile devices, and fixed infrastructure, without requiring any prior exchange of account data or PINs. The only prerequisite for immediate interaction is physical proximity. Examples from my current research will illustrate this  concept.

SACHI Seminar: Alix Goguey (University of Saskatchewan) – Augmenting touch expressivity to improve the touch modality


Event details

  • When: 1st November 2017 13:15 - 14:15
  • Where: Honey 103 - GFB

 

Title

Augmenting touch expressivity to improve the touch modality

Abstract

During the last decades, touch surfaces have become more and more ubiquitous. Whether on tablets, on smartphones or on laptops, touch surfaces are used by a majority of us on a daily basis. However, the limited expressivity – the different channels used to convey information to the system – of the touch modality restricts drastically the amount of features that can be controlled via touch only. For instance, a typical smartphone touchscreen only provides the absolute position of a contact on the screen, thus applications usually offer only one way to carry out tasks (which can augment user frustration or cap performances) or restrict possibilities (e.g. Photoshop on desktop offers more than 600 commands but only about 40 on smartphones and tablets). In this talk, I will present an overview of my on-going research and discuss different ways to tackle this problem, augment touch expressivity and user efficiency: from tools that helps better designing touch interfaces to the use of new input dimensions in original interaction techniques.

Event details

  • When: 7th November 2017 14:00 - 15:00
  • Where: Cole 1.33a

Title:

Visualization and Taxonomy

Abstract:

This talk will consider the relationship between visualization and taxonomy from two perspectives. Firstly, how visualization can aid understanding the process of taxonomy, specifically biological taxonomy and the visualization challenges this poses. Secondly, the role of taxonomy in understanding and making sense of the growing field of visualization will be discussed and the challenges facing the visualization community in making this process more rigorous will be considered.

Speaker Bio:

Jessie joined Edinburgh Napier University in 1986 as a lecturer, was promoted to Senior Lecturer, Reader, and then Professor in 2000 Thereafter she held the post of Director of the Institute for Informatics and Digital Innovation from 2010-14 and is currently Dean of Research and Innovation for the University.

Jessie has published widely, with over 100 peer-reviewed publications and over £2 million in research funding from a range of bodies, including EPSRC, BBSRC, National Science Foundation, and KTP, and has had 13 PhD students complete. She has been programme chair, programme committee member and organiser of many international conferences, a reviewer and panel member for many national and international computer science funding bodies, and became a Member of EPSRC Peer Review College in 1996 and a Fellow of the British Computer Society.

Jessie has a long-standing record of contribution to inter-disciplinary research, working to further biological research through the application of novel computing technology.

Her research in the areas of user interfaces to databases and data visualisation in biology contributed to the establishment of the field of biological visualisation. She hosted the first biological visualisation workshop at the Royal Society of Edinburgh in 2008, was an invited speaker at a BBSRC workshop on Challenges in Biological Visualisation in 2010, was a founding member of the International Symposium in Biological Visualisation – being Programme Chair in 2011, General Chair in 2012 and 2013 – and steering committee member since 2014.

She has been keynote speaker at related international conferences and workshops, such as VIZBI, the International Visualisation conference and BioIT World, and is currently leading a BBSRC network on biological visualisation.

Her research in collaboration with taxonomists at the Royal Botanic Gardens, Edinburgh, produced a data model for representing differing taxonomic opinions in Linnaean classification. This work led to collaboration on a large USA-funded project with ecologists from six US universities and resulted in a data standard for the exchange biodiversity data that has been adopted by major global taxonomic and biodiversity organisations.
