Ben Lafreniere of the University of Saskatchewan visited the DGP to talk about rehearsal-based interfaces.

BIO

Ben Lafreniere is a Human-Computer Interaction researcher who specializes in the areas of learning and skill development with interactive systems, and the usability of feature-rich software. In 2014 he received a PhD in Computer Science from the University of Waterloo for his work on developing task-centric user interfaces. He is currently a Postdoctoral Fellow with the Interaction lab at the University of Saskatchewan.

ABSTRACT

Rehearsal-based interfaces are designed to enable a smooth transition from novice to expert performance by making the novice user’s visually-guided actions a physical rehearsal of the expert’s feedback-free actions. While a number of examples of these interfaces have been developed, including Marking Menus and FastTap menus, there is little published data on how skill development happens in real use of these interfaces. In this talk I will describe two studies we conducted on skill development in rehearsal-based interfaces: one in a game that directly rewards rapid menu selections, and another in a drawing application that has no particular need for urgency. Our results show very different patterns of adoption in these two applications, and suggest that rehearsal of physical actions alone does not guarantee that users will adopt expert methods. I will also discuss insights into what affects use of expert methods by users, and the implications of our findings for how rehearsal-based techniques should be employed in practice. Finally, I will discuss ongoing research that builds on this work.

Design for Human Experience and Expression: Research at MAGIC and the HCT Laboratory

ABSTRACT

Research at the Media and Graphics Interdisciplinary Centre (MAGIC; www.magic.ubc.ca) and the Human Communications Technology (HCT) laboratory (hct.ece.ubc.ca) has been targeting design for human experience and expression. In this presentation, I’€™ll start with a discussion of gesture-to-speech and voice explorations, including Glove-TalkII and the Digital Ventriloquized Actors (DIVAs). I’€™ll connect these to other explorations of the new interfaces for musical and visual expression that we have created.  I’€™ll then show some more work on new forms of personalized video viewing that we call the MyView system. MyView creates a new viewing experience though integrating human memory patterns into the navigation, browsing, annotation, authoring and sharing mechanisms. I will briefly discuss our work on modelling human anatomy (www.parametrichuman.org) and function, such as speaking, chewing, swallowing and breathing (www.magic.ubc.ca/OPAL.htm) with biomechanical models using our toolkit Artisynth (www.artisynth.org). This work is motivated by our quest to make a new vocal instrument that can be controlled by gesture. I’ll discuss some of the activities we have been doing on some new 3D displays: pCubee and Spheree. Finally, these investigations will be used to support a theory of designing for intimacy and discussions of perspectives on human computer interaction for new experiences and forms of expression.

Crowdsourcing a Meeting of Minds

ABSTRACT

Crowdsourcing is an increasingly powerful method for combining amateurs’ efforts to recreate an expert’s abilities. However, across domains from design to engineering to art, few goals are truly the effort of just one person — even one expert. If we can now crowdsource simple tasks such as image labeling, how might we computationally coordinate many peoples’ abilities toward far more complex and interdependent goals? In this talk, I present computational systems for gathering and guiding crowds of experts — including professional programmers, designers, singers and artists. The resulting collectives tackle problems modularly and at scale, dynamically grow and shrink depending on task demands, and combine into larger organizations. I’ll demonstrate how computationally-enabled expert crowds can pursue goals such as designing new user experiences overnight, producing animated shorts in two days, and even pursuing novel research.

Interacting with Small Devices in Big Ways.

ABSTRACT

Eight years ago, multi-touch devices went mainstream, and changed our field, the industry and our lives. In that time, mobile devices have gotten much more capable, yet the core user experience has evolved little. Contemporary touch gestures rely on poking screens with different numbers of fingers: one-finger tap, two-finger pinch, three-finger swipe and so on. We often label these as “natural” interactions, yet the only place I perform these “gestures” is on my touchscreen device. We are also too quick to blame the “fat finger” problem for much of our touch interface woes – if a zipper or pen were too small to use, we would simply call that “bad design”. Fortunately, our fingers and hands are amazing, and with good technology and design, we can elevate touch interaction to new heights. I believe the era of multi-touch is coming to a close, and that we are on the eve of an exciting new age of “rich-touch” devices and experiences.

Dr. Ali Mazalek Presents a Talk at DGP

Dr. Ali Mazalek, Associate Professor of Ryerson University and Georgia Tech will be visiting our lab on Thursday, December 4th. She will be presenting a talk between 11:00 am until 12:30 pm.

Welcome to DGP, Dr. Mazalek!

“Mind, material, and movement: embodying creativity in the digital era”

Abstract

We are increasingly tethered to a range of pixelated boxes of varying shapes and sizes. These devices are ever present in our lives, transporting us daily into vast information and computational realms. And while our interactions with digital devices are arguably becoming more fluid and “natural”, they still make only limited use of our motor system and largely isolate us from our immediate physical surroundings. Yet a gradual shift in the cognitive sciences toward embodied paradigms of human cognition can inspire us to think about why and how computational media should engage our bodies and minds together. What is the role of physical movements and materials in the way we engage with and construct knowledge in the world? This talk will provide some perspectives on this question, highlighting research from the Synaesthetic Media Lab that supports creativity and expression across the physical and digital worlds.

Biography
Dr. Ali Mazalek has spent over 15 years trying to get digital technologies to fit better into her physical world and life, rather than letting them drag her into the pixelated depths of her computer screens. At the same time, she has a deep interest in how computational media can support and enhance creative practices and processes, supporting new forms of expression and new ways of thinking and learning. She is a Canada Research Chair in Digital Media and Innovation and Associate Professor in the RTA School of Media at Ryerson University, as well as Associate Professor of Digital Media at Georgia Tech. Her Synaesthetic Media Lab ( synlab.gatech.edu) is a playground where physical materials, analog sensors, and digital media happily co-exist and come together in novel ways to support creativity and expression across both science and art disciplines.

Professor Michael Terry Speaking at DGP

Professor Michael Terry will be presenting a talk on Thursday, November 20th from 11:00 am until 12:30 pm in room BA5187.

Please join us in welcoming Professor Terry!

“Interactive Systems Need to Know How to Read the Web and Watch YouTube”

In this talk, Professor Michael Terry will argue that there is great value in interactive systems that can learn how to accomplish tasks by “reading” web-based tutorials and “watching” how-to videos. He will focus primarily on text-based documents and search queries, and show how techniques from the fields of machine learning and information retrieval can be leveraged to extract streams of “how-to” information from web-based resources and instrumentation logs. These information sources enable a new class of interactive system that is more aware of the tasks it can perform, as well as how to accomplish these tasks. Importantly, this awareness continually evolves and tracks how the user community actually uses the system.
