While the technologies become more mainstream, the remaining open question is how to interact with such hybrid workstations that combine 2D views displayed on a physical monitor and 3D views displayed on a HoloLens. For a selection task, we compared mouse-based interaction (standard for 2D desktop workstations) and direct touch interaction in mid-air (standard for 3D AR) while considering different positions of the 3D scene according to a physical monitor. To extend mouse-based selection to 3D views, we experimentally explored different interaction metaphors where the mouse cursor moves either on a horizontal or a vertical plane in a 3D virtual scene. To check for ecological validity of our results, we conducted an additional study focusing on interaction with a 2D/3D Gapminder dataset visualization. The results show 1) that the mouse-based interaction, as compared to direct touch interaction in mid-air, is easy and efficient, 2) that using a vertical plane placed in front of the 3D virtual scene to mimic the double screen metaphor outperforms other interaction techniques and 3) that flexibility is required to allow users to choose the selection techniques and to position the 3D virtual scene relative to the physical monitor. Based on these results, we derive interaction design guidelines for hybrid workstations.", "authors": { "1": { "first_name": "Carole", "last_name": "Plasson" }, "2": { "first_name": "Renaud", "last_name": "Blanch" }, "3": { "first_name": "Laurence", "last_name": "Nigay" } }, "year": 2022, "uri": "http://iihm.imag.fr/publication/PBN22a/", "pages": "460-469", "bibtype": "inproceedings", "id": 947, "abbr": "PBN22a", "address": "Singapore, Singapore", "date": "2022-10-17", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "2022 IEEE International Symposium on Mixed and Augmented Reality (ISMAR)", "type_publi": "icolcomlec" }, { "lang": "en", "publisher": "Société Informatique de France", "type_publi": "autre", "title": "Projet ANR (2015-2018) « Autour du plan 2D »", "url": "https://hal.archives-ouvertes.fr/hal-03655986", "journal": "1024 : Bulletin de la Société Informatique de France", "year": 2022, "number": 19, "uri": "http://iihm.imag.fr/publication/CCC+22a/", "bibtype": "unpublished", "abbr": "CCC+22a", "authors": { "1": { "first_name": "Julien", "last_name": "Castet" }, "2": { "first_name": "Florent", "last_name": "Cabric" }, "3": { "first_name": "Adrien", "last_name": "Chaffangeon Caillet" }, "4": { "first_name": "Dominique", "last_name": "Cunin" }, "5": { "first_name": "Emmanuel", "last_name": "Dubois" }, "6": { "first_name": "Elio", "last_name": "Keddisseh" }, "7": { "first_name": "Yann", "last_name": "Laurillau" }, "8": { "first_name": "Laurence", "last_name": "Nigay" }, "9": { "first_name": "Michael", "last_name": "Ortega" }, "10": { "first_name": "Gary", "last_name": "Perelman" }, "11": { "first_name": "Carole", "last_name": "Plasson" }, "12": { "first_name": "Mathieu", "last_name": "Raynal" }, "13": { "first_name": "Houssem", "last_name": "Saidi" }, "14": { "first_name": "Marcos", "last_name": "Serrano" } }, "date": "2022-04-01", "type": "Autres publications", "id": 933 }, { "lang": "en", "type_publi": "icolcomlec", "doi": "https://doi.org/10.1007/978-3-030-85610-6_28", "title": "A Lens-Based Extension of Raycasting for Accurate Selection in Dense 3D Environments", "url": "https://hal.archives-ouvertes.fr/hal-03355685", "booktitle": "Human-Computer Interaction – INTERACT 2021", "authors": { "1": { "first_name": "Carole", "last_name": "Plasson" }, "2": { "first_name": "Dominique", "last_name": "Cunin" }, "3": { "first_name": "Yann", "last_name": "Laurillau" }, "4": { "first_name": "Laurence", "last_name": "Nigay" } }, "year": 2021, "uri": "http://iihm.imag.fr/publication/PCL+21b/", "id": 927, "bibtype": "inproceedings", "abbr": "PCL+21b", "address": "Bari, Italy", "date": "2021-08-30", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "pages": "501-524" }, { "lang": "fr", "type_publi": "these", "title": "2D/3D Interaction in Tabletop Augmented Reality", "url": "https://tel.archives-ouvertes.fr/tel-03323142", "abstract": "This thesis contributes to the research field of Human-Computer Interaction (HCI). The focus of the research is on tabletop Augmented Reality (AR) interaction. Allowing visualization of 3D virtual information linked to a table that acts as a physical support for interaction is one of the main advantages of tabletop AR.Tabletop AR systems thus define a relevant alternative to the often complex desktop software used to create and visualize 3D models (3D modeling, CAD, urban planning, architecture).Currently, these systems use mid-air interaction techniques inherited from classical AR that mimic the manipulation of physical objects. Although intuitive and direct, these techniques are often imprecise and tiring for long-term use.Tabletop AR systems also allow tactile interaction on the table which is more precise but less intuitive for 3D tasks than 3D mid-air interaction. In this context, the research question of our work concerns the design of 3D object selection techniques in tabletop AR that are precise, not tiring, and easy to handle and use.The design space to be explored is vast and includes selection techniques based on tactile interaction on the table, mid-air interaction above the table, and hybrid interaction combining the two interaction spaces i.e. the table and the space above the table. The exploration of this vast design space gave rise to three contributions.Our first contribution is to identify which AR device, between a head-mounted display (HMD) and a handheld device (smartphone/tablet), is the most efficient for the visualization and selection of 3D objects. The experimental results show better performance and user feedback with an HMD. We have therefore focused on tabletop AR with an HMD in our subsequent work.Our second contribution concerns the selection of distant 3D objects. We propose a new bi-manual technique, namely textit{RayLens}, to improve the accuracy of distant object pointing. textit{RayLens} combines a ray and a 2D magnifying lens that can be moved in 3D. This technique has proven to be efficient, not tiring, and particularly appreciated by the users thanks to its ease of use and intuitiveness.Finally, our third contribution focuses on the precise selection of objects at hand and further develops the use of the table as an input space for interaction. By experimentally comparing the three interaction spaces provided in tabletop AR (2D table space, 3D space above the table, hybrid space), we highlight the importance of the table support in improving accuracy and reducing fatigue. We also show the effectiveness of hybrid techniques that successfully combine the accuracy of tactile interaction with the speed of mid-air interaction.", "year": 2021, "uri": "http://iihm.imag.fr/publication/P21a/", "bibtype": "phdthesis", "abbr": "P21a", "authors": { "1": { "first_name": "Carole", "last_name": "Plasson" } }, "date": "2021-05-04", "type": "Thèses et habilitations", "id": 930 }, { "lang": "en", "publisher": "ACM", "doi": "https://doi.org/10.1145/3399715.3399836", "title": "3D Tabletop AR: A Comparison of Mid-Air, Touch and Touch+Mid-Air Interaction", "url": "https://hal.archives-ouvertes.fr/hal-02960637", "abstract": "This paper contributes a first comparative study of three techniques for selecting 3D objects anchored to the table in tabletop Augmented Reality (AR). The impetus for this study is that touch interaction makes more sense when the targeted objects are anchored to the table. We experimentally compare touch and a mixed (touch+mid-air) techniques with the common direct mid-air technique. The touch and mixed techniques involve a decomposition of the 3D task into a 2D task by touch on the table followed by a 1D task by touch or mid-air interaction. Results show that: (1) The touch and mixed techniques present completion times similar to the mid-air technique and are more accurate than the mid-air technique; (2) The mixed technique defines a good compromise between accuracy of touch interaction and speed of mid-air interaction.", "authors": { "1": { "first_name": "Carole", "last_name": "Plasson" }, "2": { "first_name": "Dominique", "last_name": "Cunin" }, "3": { "first_name": "Yann", "last_name": "Laurillau" }, "4": { "first_name": "Laurence", "last_name": "Nigay" } }, "year": 2020, "uri": "http://iihm.imag.fr/publication/PCL+20a/", "pages": "1-5", "bibtype": "inproceedings", "id": 886, "abbr": "PCL+20a", "address": "Ischia Island, Italy", "date": "2020-09-28", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "AVI '20: International Conference on Advanced Visual Interfaces", "type_publi": "icolcomlec" }, { "lang": "en", "type_publi": "colloque", "doi": "https://doi.org/10.1145/3343055.3360760", "title": "Tabletop AR with HMD and Tablet: A Comparative Study for 3D Selection", "abstract": "We experimentally compare the performance and usability of tablet-based and see-through head-mounted display (HMD)-based interaction techniques for selecting 3D virtual objects projected on a table. This study is a first step toward a better understanding of the advantages and limitations of these interaction techniques, with the perspective of improving interaction with augmented maps. To this end, we evaluate the performance of 3 interaction techniques in selecting 3D virtual objects in sparse and dense environments: (1) the direct touch interaction with a HMD; (2) the ray-casting interaction with a HMD; and (3) the touch interaction on a tablet. Our results show that the two techniques using a HMD are faster, less physically tiring and preferred by the participants over the tablet.
