The domain of action understanding concerns the investigation of the psychological mechanisms which enables us to make sense of the transformations perceived within the environment. We consider two aspects of action understanding: the segmentation of dynamical sequences, and the intuitive perception of certain causal and intentional components of a...

Visual working memory performance often declines when objects are tested in new positions from those they were observed. We report an asymmetry in repositioning costs for orientation compared to colour memory (Experiment 1). Follow-up experiments demonstrated a similar asymmetry for line length memory compared to shape memory (Experiment 2). When d...

As video games become a widespread form of entertainment, there is need to develop new eval-uative methodologies for acknowledging the various aspects of the player's subjective experience, and especially the emotional aspect. Video game developers could benefit from being aware of how the player reacts emotionally to specific game parameters. In t...

To mentally extrapolate the trajectory of a moving object that disappears from sight, different sources of information can be exploited: memory of its last visible position, its inferred movement through time, and general understanding of the causal structure of the scene. It is often assumed that these cues are integrated into unified analog menta...

Many people are fascinated by biological swarms, but understanding the behavior and inherent task objectives of a bird flock or ant colony requires training. Whereas several swarm intelligence works focus on mimicking natural swarm behaviors, we argue that this may not be the most intuitive approach to facilitate communication with the operators. I...

Cet article s’attache à la forme de collectif d'objets à comportements (coco2) dans l'art contemporain et l'internet des objets (IoT). Les auteurs examinent comment des groupes d'objets interagissent entre eux et avec le public de différentes manières : en tant que spectateurs observant des processus autonomes, en tant que visiteurs explorant des i...

When faced with the need of implementing a decentralized behavior for a group of collaborating robots, strategies inspired from swarm intelligence often avoid considering the human operator, granting the swarm with full autonomy. However, field missions require at least to share the output of the swarm to the operator. Unfortunately, little is know...

The control of multiple robots in the context of tele-exploration tasks is often attentionally taxing, resulting in a loss of situational awareness for operators. Unmanned aerial vehicle swarms require significantly more multitasking than controlling a plane, thus making it necessary to devise intuitive feedback sources and control methods for thes...

We tackle the issue of expressive movement in non-humanlike robots, conducting a study with the goal of providing a characterization of expressive qualities embedded in the movements of a simple robot. We provide evidence that expressivity can be considered as a distinct modality of evaluation, distinct from other ways to consider a movement. Our f...

Faced with an overload of dematerialized information, would it be possible to propose an aesthetic, sensitive, even affective relationship with a cloud of information, thought of as a living and malleable entity? Would it be possible to interact in immersion with my data, to tame it, to sculpt it, to reclaim it for myself? Our purpose is to create...

The robotics community is considering the use of large groups of robots, also known as artificial swarms for applications in unknown and dynamic environments. In this context, swarms of robot will need to interact with users to accomplish their mission. Unfortunately, little is known about the users' perception of group behavior and dynamics, as we...

This article raises the issue of collaboration between the field of dance and that of robotics. Dance notation systems are developed in the choreographic field as a method to describe and record human movements. Translating movements into symbols is of particular concern for computer science and robotics, which are interested in generating anthropo...

A new race of artifacts comes equipped with behavioral properties. Those properties transmute the very nature of the object, granting it a life of its own and a special status that stems from the psychological attributions humans naturally produce when confronted by autonomous movements. This article examines what makes behavioral objects special i...

Art installations involving robotic artifacts provide an opportunity to examine human relationships with robots designed solely for the purpose of sustaining evocative behaviours. In an attempt to determine the behavioural characteristics and personality traits attributed by a human to a robotic artifact, we investigated an audience’s experience of...

Among robots, non-anthropomorphic robotic artifacts are in an interesting position: the fact that they do not resemble living beings, yet impart a sense of agency through the way they move, motivates to consider motion as a source of expressivity in itself, independently of any morphological cues. This problematic is considered in parallel to the q...

In contemporary art, a new type of artworks use motion as a material from which to create the illusion of life. These autonomous robotic artworks have a behavioral specificity; they tend to be perceived as living, and by some account intentional entities. To account for this behavioral specifity and how it affects the audience experience, we propos...

While the movement toward granting ever more power to users is very real, can we understand it not from the viewpoint of humans, but that of the objects? How can we design the empowerment of both users and objects, but starting from the objects? Could the object then change its status and become a subject, or at least an agent? With that as our sta...

In an attempt to uncover some of the rules governing event perception, we designed a case of causal competition in which two events can both be perceived as causing a third event. A launching effect occurred when a red disc (B), after being contacted by a black disc (A), started to move immediately with the same speed and in the same direction as A...

Résumé Le domaine de la compréhension de l’action concerne l’étude des mécanismes psychologiques qui permettent de donner sens aux transformations perçues dans l’environnement. Nous considérons deux aspects de la compréhension de l’action : la segmentation de séquences dynamiques, et la perception intuitive de certaines composantes causales et inte...

Background / Purpose: To mentally extrapolate the trajectory of a moving object that disappears from sight, it is often assumed that different cues, such as the inferred movement and the understanding of the causal structure of the scene, are integrated into unified analog mental representations.In our experiment, participants predicted the posit...

In the recent years video games have enjoyed a dramatic increase in popularity, the growing market being echoed by a genuine interest in the academic field. With this flourishing technological and theoretical efforts, there is need to develop new evaluative methodologies for acknowledging the various aspects of the player's subjective experience, a...

To mentally extrapolate the trajectory of a moving object which disappears from sight, it is possible to exploit two different sources of information. One source is the memory of the last visible movement of the object, and the other is its inferred movement through time. It is often assumed that these cues are integrated into dynamical analog ment...
