Different softness can impact the deformation of UIs when worn and touched, and thus impact the users' perception of the curvature. To investigate how softness impacts users’ perception of curvature, we measured participants’ curvature perception accuracy and precision in different softness conditions. We found that participants perceived the curviest surfaces with similar precision in all different softness conditions. Participants lost half the precision of the rigid material when touching the flattest surfaces with the softest material. Participants perceived all curvatures with similar accuracy in all softness conditions.

The problem we tackle in this paper is to find the range of usable sizes of such modules, to better inform the trade-off between usability and technological feasibility. We assessed four sliders in a controlled user study: a standard slider and three sliders made of mock-up rounded modules of ø1 mm, ø2.5 mm, and ø5 mm. Experimental results show that (1) ø5 mm modules significantly impair performance for the pursuit task and subjective perception for both tasks, (2) performance increases when the size of modules decreases, but (3) users reportedly enjoyed the haptic feedback provided by ø1 mm to ø2.5 mm modules.

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 interaction mostly focused on the preferred hand, even though users cannot avoid in real life to handle their phone with their non-preferred hand. To better design one-handed BoD interaction tailored for each hand, the identification and measure of the impact of their asymmetry are critical. In this paper, we study the impact on the performance of the asymmetry between the preferred and the non-preferred hands when interacting with one hand in the back of a mobile touch surface. Empirical data indicates that users' preferred hand performs better than the non-preferred hand in target acquisition tasks, for both time (+10%) and accuracy (+20%). In contrast, for steering tasks, we found little difference in performance between users' preferred and non-preferred hands. These results are useful for the HCI community to design mobile interaction techniques tailored for each hand only when it is necessary.

To overcome this problem, this paper sets out to experimentally study an extendable tangible slider to support one-handed clutching.

This low-fidelity prototype significantly improves performance when reaching distant targets, as compared to a standard tangible slider. We then built a higher-fidelity prototype, introducing actuation and allowing for a shorter knob. When used for clutching, the knob moves back towards the users’ thumb. Experimental results show that the motion of the actuated knob does not interrupt eyes-free interaction during manipulation.

The results show that a concurrent feedback, which visually simplifies the 3D scene during the execution of the gesture, increases the recognition rate, but only during the first two repetitions. After the first two repetitions, users achieve the same recognition rate with a terminal feedback (after the execution of the gesture), a concurrent feedback, both or neither. With respect to feedforward, the overall stability of the 3D scene explored through the origin of the pipes during the execution of the gestures does not influence the recognition rate or the execution time.

Les dispositifs artistiques interactifs mettent fréquemment en œuvre une simulation, qu’il s’agisse de la représentation en perspective d’un espace tridimensionnel simulé par ordinateur ou de compositions graphiques générées à partir d’algorithmes. Mais, afin de faire œuvre, ces dispositifs doivent prendre une forme concrète pour pouvoir s’offrir à l’expérimentation du spectateur. Cette matérialisation du dispositif interactif permet à l’œuvre d’exister. La continuité se définit, quant à elle, comme la liaison non interrompue des parties d’un tout. Cette notion s’applique aux mondes physique et numérique lorsque, en art comme en science, les chercheurs tentent de réunir en un tout la simulation numérique et la matérialisation physique.\r\nNous aborderons dans cet article la notion de continuité entre simulation et matérialisation, tout d’abord du point de vue artistique, puis de celui des sciences de l’ingénieur, pour observer enfin comment ces disciplines interagissent dans l’étude et la réalisation d’interfaces.", "year": 2012, "uri": "http://iihm.imag.fr/publication/CCO+12a/", "id": 587, "bibtype": "inbook", "editor": "Samuel Bianchini, Nathalie Delprat, Christian Jacquemin", "authors": { "1": { "first_name": "Céline", "last_name": "Coutrix" }, "2": { "first_name": "Dominique", "last_name": "Cunin" }, "3": { "first_name": "Mayumi", "last_name": "Okura" }, "4": { "first_name": "Marcos", "last_name": "Serrano" } }, "date": "2012-01-01", "type": "Chapitres d'ouvrages", "booktitle": "SIMULATION TECHNOLOGIQUE ET MATÉRIALISATION ARTISTIQUE : Une exploration transdisciplinaire arts/sciences", "abbr": "CCO+12a" }, { "lang": "en", "type_publi": "colloque", "title": "Pointing in the Physical World for Light Source Selection", "abstract": "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 based on the pointing paradigm, that is, allowing interaction at a distance. To address the limitations of the pointing paradigm (e.g., aiming at distant and/or small targets), we design a two-step pointing technique: a rough aiming with an arm pointing gesture and a disambiguation mechanism with a wrist rolling gesture. Feedbacks lean on the various capacities of LED lights. We expect that our technique is well suited for the selection task in dense environments, no matter how small and how distant the targeted light sources are. We also expect that the technique supports an efficient interaction based on proprioception and muscular memory properties for expert users, who may perform the two interaction steps by a single combined gesture for better performance.", "address": "Newcastle, UK", "year": 2012, "uri": "http://iihm.imag.fr/publication/DCN12a/", "id": 588, "bibtype": "inproceedings", "abbr": "DCN12a", "authors": { "1": { "first_name": "William", "last_name": "Delamare" }, "2": { "first_name": "Céline", "last_name": "Coutrix" }, "3": { "first_name": "Laurence", "last_name": "Nigay" } }, "date": "2012-05-03", "document": "http://iihm.imag.fr/publs/2012/workshopDIS12.pdf", "type": "Autres conférences et colloques avec actes", "booktitle": "Proceedings of Designing Interactive Lighting workshop at DIS 2012" }, { "lang": "en", "type_publi": "icolcomlec", "title": "OP: A Novel Programming Model for Integrated Design and Prototyping of Mixed Objects", "abstract": "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 have to use distinct tools, on the one hand, tools for designing ideas and on the other hand tools for prototyping them: this makes the design process difficult. To help alleviate these two problems, we present OP (Object Prototyping), a toolkit that provides a new programming model focusing on mixed objects and allows us to seamlessly go back and forth from conceptual ideas to functional physical prototypes, making the iterative design process smooth and integrated. Indeed, OP is explicitly based on an existing conceptual design model, namely the Mixed Interaction Model that has been shown to be useful for exploring the design space of mixed objects. Our user studies show that, despite its threshold, designers and developers using OP can rapidly prototype functional physical objects as part of a design process deeply intertwining conceptual design with prototyping activities.", "authors": { "1": { "first_name": "Céline", "last_name": "Coutrix" }, "2": { "first_name": "Laurence", "last_name": "Nigay" } }, "year": 2011, "uri": "http://iihm.imag.fr/publication/CN11a/", "pages": "54-72", "bibtype": "inproceedings", "id": 566, "abbr": "CN11a", "address": "Lisbon, Portugal", "date": "2011-09-08", "document": "http://iihm.imag.fr/publs/2011/Interact2011-OP-Coutrix.pdf", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "Proceedings of the 13th IFIP TC13 Conference on Human-Computer Interaction (Interact'11), Part III, 5-9 September 2011, Lisbon, Portugal, Springer, LNCS 6948" }, { "bibtype": "article", "publisher": " Springer-Verlag", "type_publi": "irevcomlec", "lang": "en", "uri": "http://iihm.imag.fr/publication/CYC+09a/", "title": "Mobile phone-based mixed reality: the Snap2Play game", "url": "http://www.springerlink.com/content/r67768q66173k1lx/", "journal": "The Visual Computer, Springer-Verlag Publ., ISSN 0178-2789 (Print) 1432-2315 (Online)", "year": 2009, "number": 1, "pages": "25-37", "volume": 25, "id": 1, "abbr": "CYC+09a", "authors": { "1": { "first_name": "Tat-Jun", "last_name": "Chin" }, "2": { "first_name": "Yilun", "last_name": "You" }, "3": { "first_name": "Céline", "last_name": "Coutrix" }, "4": { "first_name": "Joo-Hwee", "last_name": "Lim" }, "5": { "first_name": "Jean-Pierre", "last_name": "Chevallet" }, "6": { "first_name": "Laurence", "last_name": "Nigay" } }, "date": "2009-01-01", "document": "http://iihm.imag.fr/publs/2009/TheVisualComputer-Snap2Play-Chin.pdf", "type": "Revues internationales avec comité de lecture", "abstract": "The ubiquity of camera phones provides a convenient platform to develop immersive mixed-reality games.

In our game, the players are asked to match a “digital card”, which corresponds to a scene in a virtual world, to a “physical card”, which is an image of a scene in the real world. The objective is to convey a mixed-reality sensation. Cards are matched with a scene identification engine which consists of multiple classifiers trained on previously collected images. We present our comprehensive overall game design, as well as implementation details and results. We also describe how we constructed our scene identification engine and its performance.

Mixed systems can take various forms and include augmented reality, augmented virtuality, and tangible systems. In this very dynamic context, it is difficult to compare existing mixed systems and to systematically explore the design space. Addressing this design problem, this chapter presents a unified point of view on mixed systems by focusing on mixed objects involved in interaction, i.e. hybrid physical-digital objects straddling physical and digital worlds. Our integrating framework is made of two complementary facets of a mixed object: we define intrinsic characteristics of an object as well as extrinsic characteristics of an object by considering its role in the interaction. Such characteristics of an object are useful for comparing existing mixed systems at a fine-grain level. The taxonomic power of these characteristics is discussed in the context of existing mixed systems from the literature. Their generative power is illustrated by considering a system, Roam, which we designed and developed.", "year": 2009, "uri": "http://iihm.imag.fr/publication/CN09a/", "id": 456, "bibtype": "inbook",
