Democratization of augmented reality head-mounted displays from a text entry perspective in work environments ; Démocratisation des visiocasques de réalité augmentée : perspective de la saisie de texte dans des environnements de travail
Many people predict a massive use of augmented reality head-mounted displays in different areas already explored by research, including health, education, entertainment and industry. Each of these areas involves scenarios with significant and ubiquitous text input activity, whether for a username or password, annotation of documents or virtual objects, a comment, a report or for sending messages. However, the contexts of use and the characteristics of these augmented reality head-mounted displays imply new interfaces beyond the usual framework of the keyboard-mouse couple or the tactile surface already adopted by the personal computer and the smartphone. In that regard, several text entry interfaces for head-mounted displays have been suggested, implemented and studied, through the recognition of gestures such as those of the hands, head or gaze, up to specific peripherals, such as controllers, gloves or rings, but none adequately responds to the constraints imposed by augmented reality for industrial and office work environments. Within the limits of these contexts supported by our industrial partner, this thesis attempts to address this problem by offering two new complementary text entry interfaces dedicated to augmented reality head-mounted displays. The first solution dedicated to the industrial environment invites users to combine a smartwatch with the head-mounted display to offer a multimodal interface adapted to difficult situations. The second solution dedicated to the office environment, invites users to handle a cubic device offering similar characteristics than traditional keyboards while being mobile. We adopted iterative user-centered design methods to implement parts of our solutions, and followed an empirical research approach including eight experiments to study and compare them. Finally, the analysis of the work allows us to develop and illustrate how our solutions can evolve to reach other contexts and activities, and thus actively participate in the democratization of augmented reality ...
