Human-Computer Interaction: New Challenges / PERSYVAL-Minalogic Breakfasts

HCI is the discipline dedicated to the design, implementation, and evaluation of interactive computer systems intended for human users, as well as the study of the main phenomena underlying human-computer interaction. An interactive system must be adapted to the perceptual, motor, and cognitive capabilities of its users: the usability of a system thus relates to human capabilities. Consequently, HCI finds itself at a unique crossroads between computer science and the humanities and social sciences.

The objective of this meeting is to provide keys to better understand the various facets of this field and connect them with specific application needs, as well as to introduce recent advances in Human-Computer Interaction. We develop two complementary aspects for advancements in HCI: the challenges of HCI in the specific context of Augmented Reality and the challenges of a new interaction modality, Brain-Computer Interfaces.

    The meteoric rise of Augmented Reality for value-added uses and applications in B2B or B2C can be explained by technological advances in terms of devices (such as tablets and headsets) and, above all, development tools. Three principles govern Augmented Reality (AR):
    1) AR combines real objects and virtual objects in a real environment
    2) AR operates interactively and in real time
    3) AR matches (in other words, aligns) real and virtual objects with each other.
    In research, AR systems pose challenges for camera position estimation systems (for example, computer vision algorithms) as well as for display devices and rendering techniques (for example, multi-depth displays and realistic illumination of digital objects). Both challenges aim to achieve the most realistic augmented view possible within the user's field of view.
    Another challenge for the effective use of AR beyond the gadget "wow" factor lies in interaction within the context of AR. In this presentation, we consider AR interaction on mobile devices, as these devices constitute the main AR visualization interface today. The device is used as a magic lens that "augments" the perception of the physical environment with digital content. We focus on the spatial relations between the content displayed on the screen and the physical environment: The question is then, how can we relax these spatial constraints to improve interaction without breaking the physical-digital co-localization?

    Brain-computer interfaces (BCIs) allow humans to communicate with electronic devices without using muscular pathways, but directly through the interpretation of brain signals. Today, they are finding a growing place in the media, supported by transhumanist movements, according to which BCI technology will make it possible to enhance human capabilities to survive against the growing power of artificial intelligence. However, BCIs were initially developed to overcome communication difficulties in humans following severe motor disorders, and BCIs remain very limited in terms of transmissible information throughput. In this presentation, we will consider the limitations of current BCIs and their prospects. We will also highlight the fundamental role of signal processing in this technology.
