MIC aims at studying and promoting microgesture-based interaction by putting it in practice in use situations. The demontrations show interaction techniques based on microgestures or on the combination of microgestures with another modality including haptic feedback as well as mechanisms that support discoverability and learnability of microgestures. The demonstrations illustrate three different contexts of use: 1) Augmented/Virtual Reality because microgesture interaction does not require us to hold any external device and is less physically demanding than mid-air interaction. 2) Car driving because microgestures may be performed in parallel with other tasks, they only require a few seconds and only one hand. 3) Eyes-free interaction (i.e. users with visual impairments) because users can perform microgestures by relying on proprioception only, without looking at their hand.", "authors": { "1": { "first_name": "Adrien", "last_name": "Chaffangeon Caillet" }, "2": { "first_name": "Aurélien", "last_name": "Conil" }, "3": { "first_name": "Alix", "last_name": "Goguey" }, "4": { "first_name": "Vincent", "last_name": "Lambert" }, "5": { "first_name": "Laurence", "last_name": "Nigay" }, "6": { "first_name": "Charles", "last_name": "Bailly" }, "7": { "first_name": "Julien", "last_name": "Castet" }, "8": { "first_name": "Michael", "last_name": "Ortega" }, "9": { "first_name": "Zoé", "last_name": "Lacroux" }, "10": { "first_name": "Céline", "last_name": "Lemercier" }, "11": { "first_name": "Pierre-Vincent", "last_name": "Paubel" }, "12": { "first_name": "Sandra", "last_name": "Bardot" }, "13": { "first_name": "Christophe", "last_name": "Jouffrais" }, "14": { "first_name": "Suliac", "last_name": "Lavenant" }, "15": { "first_name": "Sylvain", "last_name": "Malacria" }, "16": { "first_name": "Thomas", "last_name": "Pietrzak" } }, "year": 2025, "uri": "http://iihm.imag.fr/publication/CCG+25a/", "id": 1000, "bibtype": "inproceedings", "abbr": "CCG+25a", "address": "Toulouse, France", "date": "2025-11-03", "type": "Conférences internationales de large diffusion avec comité de lecture sur texte complet", "booktitle": "IHM'25 - 36e Conférence Internationale Francophone sur l'Interaction Humain-Machine" }, { "lang": "en", "type_publi": "icolcomlec", "doi": "https://doi.org/10.1145/3689050.3707690", "title": "The not-so-masochist teapot", "url": "https://hal.science/hal-04854127", "abstract": "The not-so-masochist teapot challenges the human capacity to go beyond the first impression.

However, work to-date either focuses on grasp contexts (holding an object) or on the free-hand context (no held object). These two contexts influence the microgestures feasibility. Researchers have created sets of microgesture feasible across the entire taxonomy of everyday grasps. However, those sets include a limited number of microgestures as compared to those for the free-hand context, for which microgestures are distinguished according to fine characteristics such as the part of the finger being touched or the number of fingers used. We present the first study on microgestures feasibility across free-hand and grasp contexts. We also study, for the first time, the use of finer characteristics of a microgesture in grasp context: area surface. Then, we present a set of rules to determine guess the feasibility of a microgesture in a given context without the need of doing time-consuming feasibility studies. In both studies, some microgesture were not feasible across all considered contexts.

In a first exploratory experiment we study a two-phase design and compare modalities for each phase: mid-air gestures, eye-gaze and microgestures. Results suggest that eye-gaze and microgestures are good candidates to reduce fatigue and improve interaction speed. We therefore propose two 3D selection techniques: Look&MidAir and Look&Micro. Both techniques include a first phase during which users control a cone directed along their eye-gaze. Using the flexion of their non-dominant hand index finger, users pre-select the objects intersecting this cone. If several objects are pre-selected, a disambiguation phase is performed using direct mid-air touch for Look&MidAir or thumb to finger microgestures for Look&Micro. In a second study, we compare both techniques to the standard raycasting technique. Results show that Look&MidAir and Look&Micro perform similarly.

We first studied these designs in a quantitative online experiment with 45 participants. We then conducted a qualitative laboratory experiment in Augmented Reality with 16 participants. Based on the results, we provide design guidelines on which elements of a microgesture should be represented and how. In particular, it is recommended to represent the actuator and the trajectory of a microgesture.

Our habits are changing with these mutations, and it is now not uncommon that we interact with these computers while performing other tasks, e.g. checking our GPS position on our smartwatch while biking. Over the last ten years, a new interaction modality has emerged to meet these needs, hand microgestures. Hand microgestures, simplified to microgestures, are fast and subtle movements of the fingers. They enable interaction in parallel with a main task, as they are quick and can be performed while holding an object. However, as it is a recent modality, the field of research still lacks structure and sometimes coherence. For instance, there is no convention for naming or describing microgestures, which can lead to terminological inconsistencies between different studies. Moreover, the literature focuses mainly on how to build systems to sense and recognize microgestures. Thus, few studies examine the expected properties of microgestures, such as speed or low impact on physical fatigue in certain contexts of use. As a result, this thesis focuses on the study of microgestures, from their description to their application in a specific field, i.e. Augmented Reality (AR), as well as their sensing and recognition.Our scientific approac is comprised of three steps. In the first step, we focus on the space of possibilities. After a literature review to highlight the diversity of microgestures and terminological issues, we present μGlyph, a notation to describe microgestures. Next, we present a user study to understand the constraints imposed when holding an object on the feasibility of microgestures. The results of this study were used to create a set of three rules to determine the feasibility of microgestures in different contexts, i.e. different grasps. For ease of use, we reused μGlyph to provide a visual description of these rules. Finally, we study different ways of making a set of microgestures compatible with many contexts, i.e. that each microgesture in the set is feasible in all contexts.With the space of possibilities defined, we focus on the design of systems for sensing and recognizing microgestures. After a review of such systems in the literature, we present our easily reproducible sensing systems that we implemented, resulting in two gloves. We then present a user study on the impact of wearing these gloves on the feasibility of microgestures. Our results suggest that our gloves have little impact on the feasibility of microgestures. Next, we present a more comprehensive system that recognizes both microgestures and contexts. Our studies on recognition rates suggest that our system is usable for microgesture detection, with a recognition rate of 94%, but needs to be improved for context recognition, with a rate of 80%. Finally, we present a proof-of-concept of a modular glove and a recognition system based on μGlyph to enable the unification of microgesture sensing systems.Our final step is then dedicated to interaction techniques based on microgestures. We focus on the properties of microgestures for 3D selection in AR. We have designed two 3D selection techniques based on eye-gaze and microgestures for interaction with low fatigue. Our results suggest that the combination of eye-gaze and microgesture enables fast interaction while minimizing fatigue, compared to the commonly used virtual pointer. We conclude with an extension of our techniques to integrate 3D object manipulation in AR.", "year": 2023, "uri": "http://iihm.imag.fr/publication/C23a/", "bibtype": "phdthesis", "abbr": "C23a", "authors": { "1": { "first_name": "Adrien", "last_name": "Chaffangeon Caillet" } }, "date": "2023-12-18", "type": "Thèses et habilitations", "id": 959 }, { "lang": "fr", "type_publi": "icolcomlec", "doi": "https://doi.org/None", "title": "µGlyph: a Graphical Notation to Describe Microgestures", "url": "https://hal.archives-ouvertes.fr/hal-03655062", "abstract": "Hand microgestures define a promising modality for rapid and eye-free interaction while holding or not an object.
