Nadir Weibel On Walls, Desks, Paper and Fingers: Interactions around Physical and Digital Interfaces

2nd February 2012, 3:30 - 5:00 pm
Salle 445, PCRI (how to get there ?)


Abstract: Access to information is one of the most crucial aspects of everyday life. As computation becomes ubiquitous and our environment is enriched with new possibilities for communication and interaction, the existing infrastructure of science, business, and social interaction is confronted with the difficult challenges of supporting complex tasks, mediating networked interactions, and managing the increasing availability of digital information and technology. I am investigating how to best enable access to this information in the right way, at the right time and for the right user and situation.

In this talk I will present my current research on interactive surfaces, outlining novel interaction techniques with wall-sized high-resolution displays and new ways of interacting with objects and documents on interactive desks through a combination of depth and pan-zoom cameras. I will present our approach towards managing information that span the physical and digital boundary through pen-, paper-, and finger-based interaction

Bjoern Hartmann Proton: A new input architecture for multitouch applications based on regular expressions

23rd January 2012, 3:00 - 4:30 pm
Salle 435, PCRI (how to get there ?)


Abstract: Current multitouch frameworks require application developers to write recognition code for custom gestures; this code is split across multiple event-handling callbacks. As the number of custom gestures grows it becomes increasingly difficult to 1) know if new gestures will conflict with existing gestures, and 2) know how to extend existing code to reliably recognize the complete gesture set. Proton is a novel framework that addresses both of these problems. Using Proton, the application developer declaratively specifies each gesture as a regular expression over event streams. Proton statically analyzes the set of gestures to report conflicts, and it can automatically create a recognizer for the entire set. To simplify the creation of complex multitouch gestures, Proton introduces gesture tablature, a graphical notation that concisely describes the sequencing of multiple interleaved touch actions over time. Proton contributes a graphical editor for authoring tablatures and automatically compiles tablatures into regular expressions. (more...)


Jochen "Jeff" Rick Supporting Collaborative Learning with Interactive Tabletops

30th November 2011, 4:00 - 5:30 pm
Amphi Grenat, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Abstract: Interactive tabletops allow multiple users to interact with the same large horizontal display concurrently through touch input, pen input, or moving physical objects whose position and orientation can be tracked. Based on their support for direct manipulation and multiple entry points, there is growing excitement about this technology's potential to support small group work (2-4 learners per tabletop). For instance, SMART Technologies is already selling a commercial product aimed at the classroom.

In this presentation, I provide an introduction to the research on supporting collaborative learning with interactive tabletops. I provide concrete examples from my own research on developing tabletop applications and evaluating children's use of these applications. I will address several important questions: How does the age of the participants impact the use of the technology and the nature of the collaboration? What is the value of direct manipulation? What is the value of multiple entry points? How do individual group dynamics affect the collaboration? (more...)


Mira Dontcheva Lowering the Barriers: Making it easier to learn how to use Photoshop

23th November 2011, 2:00 - 3:30 pm
salle 445, PCRI (how to get there ?)


Abstract: In the past learning how to use complex visual design software, such as Adobe Photoshop, involved taking classes and reading books. In contrast, today's photographers and visual designers are more likely to learn how to use software opportunistically, as they need to adjust a photo, create a family album, or design a website. Together with my collaborators I have been developing and studying a variety of techniques for making it easier to learn new visual design and computational photography skills. In this talk I will describe our research on instructional design, video tutorials, and games and discuss major challenges and opportunities for learning in the context of visual design tools.

Bapstiste Caramiaux Gesture analysis and modelling for real-time interaction with digital media

15th November 2011, 2:00 - 3:30 pm
PCRI Bât 650, Salle 445 (near the entrance) (how to get there ?)


Abstract: The nowadays ubiquitous use of multitouch interfaces and inertial measurement sensors put forward new usages of gestures in Human Computer Interaction. Particularly, there is a great interest in continuous gestures as the input of the interaction, as often proposed in recent interaction paradigms (for example the two fingers pinch to resize images). In this context, gesture recognition techniques could be used to further enhance interaction possibilities. (more...)


Michael McGuffin Visualizing and Interacting with Trees and Graphs

26th September 2011, Time 14:30
PCRI Bât 650, Salle 475 (near the entrance) (how to get there ?)


Abstract: This talk will cover recently published and not-yet-published work done at ETS involving trees and graphs. I will show: an evaluation of new animated transitions in visualizations of trees; a comparative analysis of the space-efficiency of drawings of trees; a taxonomy of hybrid visualizations of trees, graphs, and compound graphs (a.k.a. clustered graphs) including one hybrid that combines NodeTrix and MatLink; a technique for drawing bipartite graphs using unambiguous edge bundling with a radial layout; a bimanual (two-handed) user interface for manipulating a graph; and a multitouch interface for manipulating a graph. A multitouch 3M screen will be available at the end of the talk for audience members to try. This is joint work with students Maxime Dumas, David Guilmaine, Skand Hurkat, Sébastien Rufiange, Erick Velazquez Godinez, Christophe Viau, and Marie-Claire Willig, and Professors Christopher Fuhrman and Jean-Marc Robert. La présentation sera en anglais, mais les questions en français seront bienvenues. (more...)


Georges Grinstein One InfoVis Grand Challenge: Visualization for the Masses

20th July 2011, 15:00 - 16:30
PCRI Bât 650, Salle 455 (nord) (how to get there ?)


Abstract: Visualization is a buzzword today, the successful result of many research systems built in the last two decades. UMass Lowell with the Open Indicators Consortium (OIC) has developed yet another open-source high performance collaborative and highly flexible web-based visual analytics framework. However this system, called Weave, is a research system that brings a number of state of the art approaches which together provide a step toward the solution of one of the grand challenges in visualization, namely visualization for the masses, as well as an attack on several others. We will describe very briefly Weave, its architecture, work with the OIC, provide some demos of OIC members’ sites and highlight its state of the art aspects, the key being its session state-based architecture.

Martin Hachet 3D User Interfaces for anyone

10th June 2011, 2:30 - 4:00 pm
LRI Bât 490, Salle 79 (how to get there ?)


Abstract: Enhancing interaction between users and 3D environments is a challenging research question that is fundamental for the positive widespread of interactive 3D graphics in many fields of our societies (e.g. education and art). In this talk, I will present various 3D User Interfaces (3D UIs) we have developed these past few years, and that contribute to this general quest. In particular, I will show examples in the scope of mobile interaction, touchscreens, and immersive virtual environments. (more...)


Dustin Freeman How Users Learn Wrongly From Ambiguity in Gestural Interfaces

26th April 2011, 2:30 - 4:00 pm
LRI Bât 490, Salle 101 (how to get there ?)


Abstract: I have run a several studies with novel gestural interfaces over the last few years (touch and non-touch). I will discuss a recurring theme I have observed during every study: users misinterpreting feedback, and mis-applying what they should have learned. Interaction in a gestural interface is more ambiguous than in an interface with physical or software buttons. There is disagreement on what the "interaction" itself was between the human and the computer. I'll talk about what this means for the future of gestural interfaces, and especially how this affects Wizard-of-Oz studies. (more...)


Patrick Baudisch Multitouch + Gravity = 3D Tracking

13th April 2011, 10:30 - 12:00
LRI Bât 490, Salle 79 (how to get there ?)


Abstract: I will present a new approach to tracking people and objects in smart rooms. The main idea is to make all horizontal surfaces in a room touch sensitive. We now decode the "imprints" that objects leave on these surfaces to identify objects and people and reconstruct their pose. I will illustrate the concept with three interactive prototypes: the tangible-on-tabletop construction kit Lumino (CHI 2010), our interactive floor project Multitoe (UIST 2010), and how the concept extends to smart rooms and furniture made from drinking straws. (more...)


Catherine Plaisant Exploration of temporal sequences in medical records

11th April 2011, 2pm - 3.30pm
LRI Bât 490, Salle 79 (how to get there ?)


Abstract: I will present our recent work on the visualization of temporal patterns, with a focus on electronic health records (EHRs). Specifying event sequence queries is challenging even for skilled computer professionals familiar with SQL. Our recent projects explored novel ways to specify complex temporal searches or search by similarity. Our latest interface (LifeFlow) summarizes collections of event sequences while representing the temporal spacing of events within sequences. I will demonstrate several prototypes and discuss how we work with clinicians and hospital administrators on case studies to evaluate our strategies. Finally I will give a preview of our other projects related to electronic health record systems interfaces. (more...)


Bertjan Broeksema A Visual Tool-Based Approach to porting C++ Code

21st February 2011, 15:30 - 16:30
Amphi Emeraude, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Abstract: The sheer number of changes needed to port a code base when one of more of its dependencies need to be replaced by either a new version or another framework make it viable to develop tools that perform all or most of the required changes automatically in a reliable way. The purpose of this thesis was to research ways to support developers in the process of automated refactoring of large code bases. To this extent the type of refactoring activities involved was studied. Furthermore, a semi-automated code refactoring system based on queries and rules was developed. Transformations work directly on the source by means of insert and replace actions but are still correct due to the semantic understanding of the code by the framework. (more...)


Raimund Dachselt Natural Ways of Interacting with Information Spaces

Date 16/02/2011, 11:00-12:30
LRI Bât 490, Salle 101 (how to get there ?)


Abstract: Until now, interactive visualization techniques are often restricted to traditional input and output devices, which are typically limited to one (larger) screen operated by mouse and keyboard interaction. To find more efficient and user-friendly ways of exploring large information spaces, the User Interface & Software Engineering group of the University of Magdeburg (Germany) is conducting research on natural interaction in multiple-display environments. Thereby, we focus on interactive surfaces, in particular tabletops and mobile devices, which are operated by touch, gesture, pen or other types of tangible interaction. (more...)


Pourang Irani Blurring boundaries: Mixed input modes to alleviate common limitations with current digital environments

Date 24/01/2011, 11:00-12:00
LRI Bât 490, Salle 79 (how to get there ?)


Abstract: Digital environments, such as desktop computers, mobile devices and large surfaces depend on input mechanisms or devices to engage users in interacting with them. These input devices are partly defined by the type of mode they operate under. For example, the mouse is an indirect input device that allows one to position a desktop cursor with relative displacements of the device. A tablet pen facilitates direct input and relies on absolute positioning to control the virtual cursor. Recently, researchers have proposed techniques that allow transitioning between various input modes to harness the inherent potential available in each of these. (more...)


Koji Yatani

Date 17/01/2011, 14:00-15:00
LRI Bât 490, Salle 79 (how to get there ?)


Abstract: Mobile touch-screen devices have the capability to accept flexible touch input and can provide a larger screen than mobile devices with physical buttons. However, user interfaces on mobile touch-screen devices heavily require visual feedback. This raises a number of user interface challenges. For instance, visually-demanding user interfaces make it difficult for the user to interact with mobile touch-screen devices without looking at the screen, a task the user sometimes wishes to do particularly in a mobile setting. In addition, user interfaces on a mobile touch-screen device are not generally accessible to visually-impaired users. (more...)


Dr. Mubarak Shah Recognition: Trajectories, Bag of Video Words, and Spatiotemporal Interest Points

4th January 2011, 10:00
Amphi SAPHIR, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Ilpo Koskinen Lab, Field, Showroom: Constructive Design Research

25th November 2010, 14:30
Room B551, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Abstract This research looks at three ways in which people integrate doing design into research. Design refers explicitly to the art and design school tradition of design, with a focus on capturing vague hunches and cultural constructs, and turning them into products and systems. In the main, the book looks at industrial and interaction design, relating their growth to what the Italian designer Andrea Branzi once called "second modernity." This research has evolved from tiny beginnings into stable presence in industrial and interaction design, and is gaining importance in service design and design for sustainability. (more...)


Sergi Jordà Exploring the Synergy between Live Music Performance and Tabletop Tangible Interfaces

26th November 2010, 15:00
Amphi Jade, Télécom ParisTech - 46 rue Barrault Paris 13 - Metro Corvisart (how to get there ?)


Abstract Sergi Jordà will present the research carried in the last years within the Music Technology Group of the Universitat Pompeu Fabra, in the field of tangible and tabletop interaction, in particular for the creation of new musical instruments like the Reactable. We will study and unveil the essential reasons that turn live music performance and tabletop interaction into promising and exiting fields of multidisciplinary research and experimentation.

Mark Hancock Using Virtual Tools to Bring Physical Interaction to Multitouch Surfaces

12th November 2010, 14:30
Salle 79, LRI, Orsay (how to get there ?)

Abstract Recent advances in digital technology, both in research prototypes and commercial products, have introduced a plethora of multi-touch surfaces. Perhaps because most of these devices are flat, initially most of the interfaces designed for them were 2D in nature. However, on traditional surfaces, people frequently make use of the third dimension; for example, they pick up, turn over, stack, build, and otherwise manipulate objects on physical tables. Furthermore, they frequently use the visual cues made available by the third dimension, such as viewing the different sides of an object or scene, or hiding something underneath another object.

Sean Gustafson Imaginary Interfaces: Spatial Interaction with Empty Hands and without Visual Feedback

30th September 2010, 16:00
Amphi Saphir
Télécom ParisTech - 46 rue BARRAULT Paris 13 - Metro Corvisart
(how to get there ?)
It is required to bring an ID for the entrance.

Abstract Screen-less devices allow for the smallest form factor and thus the maximum mobility. However, current screen-less devices do not support spatial interaction (such as pointing) because, seemingly, there is nothing to point at. We challenge that notion and with a series of experiments investigate the question: to what extent can users interact spatially with a user interface that exists only in their imagination? (more...)


Ian Smith Parallel48: End-User Programming Has Already Won (But We Forgot To Tell You)

24th June 2010, 14.30
30th June 2010, 14.30
 Salle 79, LRI, Orsay (how to get there ?)
Abstract

Act I: I'll give some short background on research in end-user programming in the literature and talk about its relationships to existing products. In this act, I hope to convince you that end-user programming already "won" versus traditional software development. (I may also try to convince you that the USA was *absolutely robbed* in the match against Slovenia.) (more...)


Daniel Vogel Hand Occlusion and Direct Input

18th June 2010, 14.30
Salle 79, LRI, Orsay (how to get there ?)

Abstract

Operating a computer by touching or drawing directly on the display would seem to be more natural and efficient. However, issues specific to this kind of direct input, such as when your hand covers portions of the display while interacting, create new problems not experienced with conventional mouse input. This talk presents research investigating and addressing the problem of hand occlusion in the context of direct pen input. (more...)


Scott Hudson - Conservation of Human Attention as an Approach to New HCI Research

8th June 2010, 14.30
Salle 79, LRI, Orsay (how to get there ?)

Abstract

In 1969 Herbert Simon put forward the idea that: “in an information rich world, the scarce resource is [human] attention.” Today this would seem to be increasingly true. This talk will suggest that a number of the important challenges for modern interactive computing – including goals we describe as “invisible”, “ambient”, “pervasive”, “ubiquitous” or even “calm” – are fruitfully considered in these terms. I will suggest that traction can be gained by focusing on conservation of human attention as an organizing paradigm, describe some specific approaches to building systems in this light, and consider where the most fruitful research challenges for future work in this area may lie.

Sheelagh Carpendale - Integrating art with information visualization to create interactive tabletop applications

31st May 2010, 14.30
Salle 79, LRI, Orsay (how to get there ?)

Abstract

Integrating the arts with computer science can open doors to discovery and creation and point the way to new understandings of the aesthetic in interactions with digital technologies. I will discuss how our integrated research methodology has impacted the development of our interactive information visualizations and tabletop computing research. I will illustrate this with examples of information visualization and interactive tabletop research. (more...)
