Conference Paper
Full-text available
Shape-changing User Interfaces (UIs) explore the ability of a UI to change its physical shape to support multiple interaction modalities for users’ input and/or system’s output. An approach currently studied to implement such interfaces at a high resolution is based on mm-sized, round, and self-actuated modules. The problem we tackle in this paper...

Full-text available
Shape-changing User Interfaces attract growing interest in Human-Computer Interaction. Modular robotics offer a great opportunity for their implementation. However, the current theoretical and technical advances of modular robotics are fragmented and little centered on the user. To unify existing work and center future research on the user, we perf...
Article
One-handed Back-of-Device (BoD) interaction proved to be desired and sometimes unavoidable with a mobile touchscreen device, for both preferred and non-preferred hands. Although users? Two hands are asymmetric, the impact of this asymmetry on the performance of mobile interaction has been little studied so far. Research on one-handed BoD interactio...
Conference Paper
Sliders are ubiquitous in everyday environment, whether on our mobile devices or in objects such as the control of a sound system. The tactile feedback they offer is still very limited, even though we often use them eyes-free. In order to inform the design of the sliders' tactile information in the future, we present a qualitative study showing how...
Conference Paper
Many parameters may impact the performance of users while engaged in tangible user interaction. In this paper, we explore the impact of the combination of the tangible control and the visual display on the performance of a 1D target acquisition task. We consider three tangible controls: a slider, a knob and a wheel, and two visual displays for the...
Conference Paper
We present WiBend, a system that recognizes bending gestures as the input modalities for interacting on non-instrumented and deformable surfaces using WiFi signals. WiBend takes advantage of off-the-shelf 802.11 (Wi-Fi) devices and Channel State Information (CSI) measurements of packet transmissions when the user is placed and interacting between a...
Article
Full-text available
Professionals such as sound engineers or aircraft pilots heavily use physical knobs and sliders on their interfaces. The interfaces have advantages over touchscreen interfaces, especially when the users need to quickly and eyes-freely respond to changing situations such as when musicians are improvising, or there is smoke in a cockpit. However, unl...
Chapter
Experiencing uncertainty is common when answering questionnaires. E.g., users are not always sure to answer how often they use trains. Enabling users to input their uncertainty is thus important to increase the data’s reliability and to make better decision based on the data. However, few interfaces have been explored to support uncertain input, es...
Conference Paper
We investigate the design of a shape-changing dial, i.e. a dial that can change its circumference and height to adapt to different contexts of interaction. We first explore how users grasp 3D printed dials of different heights and circumferences in order to inform the form factor of shape-changing dials. We then design a prototype, ExpanDial, inspi...
Conference Paper
Touchscreens are the predominant medium for interactions with digital services; however, their current fixed form factor narrows the scope for rich physical interactions by limiting interaction possibilities to a single, planar surface. In this paper we introduce the concept of PickCells, a fully re-configurable device concept composed of cells, th...
Conference Paper
Uncertainty is common when working with data and becomes more important as processing big data gains attention. However, no standard tangible interface element exists for inputting uncertain data. In this article, we extend the input space of two traditional TUIs: dial and slider. We present five designs that are based on dials and sliders and supp...
Conference Paper
Full-text available
Sliders are widely used on mobile devices. Envisioning mobile devices that can dynamically deform to raise tangible controls from the screen surface, tangible sliders offer the benefit of eyes-free interaction. However, reaching for distant values with one hand is problematic: users namely need to change their handgrip, which is not comfortable. To...
Conference Paper
Physical controls are widely used by professionals such as sound engineers or aircraft pilots. In particular knobs and sliders are the most prevalent in such interfaces. They have advantages over touchscreen GUIs, especially when users require quick and eyes-free control. However, their interfaces (e.g., mixing consoles) are often bulky and crowded...
Conference Paper
Users interact with many reconfigurable objects in daily life. These objects embed reconfigurations and shape- changing features that users are familiar with. For this reason, everyday reconfigurable objects have informed the design and taxonomy of shape changing UI. However, they have never been explored systematically. In this paper, we present a...
Article
This special issue on physical computing explores flexible and shape-changing interfaces and how, by embedding computational capabilities into physical objects, we can bridge the divide between the digital and physical worlds. Shape-changing interfaces leverage users’ rich manipulation capabilities and haptic sensations and directly couple the digi...
Conference Paper
This research forms part of a wider body of work focused around involving emergent users---those just beginning to get access to mobile devices---in the development and refinement of far-future technologies. In this paper we present an evaluation of a new type of deformable slider with emergent users, designed to investigate whether shape-changing...
Conference Paper
Full-text available
Graphical sliders are widely used on mobile devices. However, with a single hand, reaching for far values is difficult : users change their grip and can drop the device. Moreover, sliders require visual attention to operate them. Envisioning mobile devices that dynamically extend tangible sliders out of the screen, the contribution of this work is...
Conference Paper
Full-text available
Touch interaction is almost omnipresent on mobile devices and technological advances have made screens bigger. The users can then interact with more content displayed on screen but it is more difficult for the users to reach all the parts of the screen with one thumb. At the same time, researchers are exploring mobile interaction with deformable ta...
Conference Paper
In this paper, we explore how to combine the advantages of physical knobs and sliders by using shape-change in order to transform one into another on-demand. By doing so we merge the benefits of both input devices: knobs enable relative angular input with dynamic gain and require little space; sliders require more space but enable absolute linear i...

Full-text available
Dynamic symbolic in-air hand gestures are an increasingly popular means of interaction with smart environments. However, novices need to know what commands are available and which gesture to execute in order to trigger these commands. We propose to adapt OctoPocus, a 2D gesture guiding system, to the case of 3D. The OctoPocus3D guidance system disp...
Conference Paper
In this paper we present the concept of Emergeables -- mobile surfaces that can deform or 'morph' to provide fully-actuated, tangible controls. Our goal in this work is to provide the flexibility of graphical touchscreens, coupled with the affordance and tactile benefits offered by physical widgets. In contrast to previous research in the area of d...

We present a tool to help practitioners to characterize, compare and design gesture guiding systems. The tool can be used to find an example system meeting specific requirements or to start exploring an original research area based on unexplored design options. The motivation for the online tool is the large underlying design space including 35 des...
Conference Paper
Full-text available
2D or 3D gesture commands are still not routinely adopted, despite the technological advances for tracking gestures. The fact that gesture commands are not self-revealing is a bottleneck for this adoption. Guiding novice users is therefore crucial in order to reveal what commands are available and how to trigger them. However guiding systems are ma...
Conference Paper
Full-text available
We address the problem of mobile distal selection of physical objects when pointing at them in augmented environments. We focus on the disambiguation step needed when several objects are selected with a rough pointing gesture. A usual disambiguation technique forces the users to switch their focus from the physical world to a list displayed on a ha...
Conference Paper
Full-text available
Several ways for selecting physical objects exist, including touching and pointing at them. Allowing the user to interact at a distance by pointing at physical objects can be challenging when the environment contains a large number of interactive physical objects, possibly occluded by other everyday items. Previous pointing techniques highlighted t...

We focus on the selection of light sources in the physical world. Their selection is challenging for the user, since numerous Light-Emitting Diodes (LEDs) can be embedded into various materials as well as environments, thus creating high densities of interactive objects. In this paper, we describe an innovative technique for light sources selection...
Conference Paper
In the context of mixed systems that seek to smoothly merge physical and digital worlds, designing and prototyping interaction involves physical and digital aspects of mixed objects. However, even though mixed objects are recurrent in the literature, none of the existing prototyping tools explicitly supports this object level. Moreover, designers h...

The ubiquity of camera phones provides a convenient platform to develop immersive mixed-reality games. In this paper we introduce such a game which is loosely based on the popular card game “Memory”, where players are asked to match a pair of identical cards among a set of overturned cards by revealing only two cards at a time. In our game, the pla...
