- W2558057147 abstract "The present work is part of that research field that has been called Human-Computer Confluence (HCC) and that aims at investigating the emerging symbiotic relationship between humans and computers. The idea of human-computer symbiosis is not novel, indeed it dates back to 1960 when Licklider borrowed from biology the notion of symbiosis between different organisms to depict a new vision of the relationship between humans and computers (Licklider, 1960). Licklider envisioned a partnership in which men set the goals, formulate the hypotheses, determine the criteria, and perform evaluations, and computers do the routinizable work. The purpose of the author was to envision a dyad in which computing machines and human brain were so tightly coupled in a mutually beneficial relationship to remember the way in which the insect Blastophaga grossorum and a fig tree relate to each other in a fruitful cooperation. The interest in symbiotic interaction has been recently renewed. This is witnessed both by the emergence of dedicated international workshops and by the recent enrichment of the scientific literature on this subject, and also by the attention and substantial funding that the European Com-mission is dedicating to projects related to this topic.The present work aims at analyzing and understanding some aspects that, at different levels, can contribute to a symbiotic relationship, in particular in the field of information exploration systems. To this end, some experiments have been conducted to investigate:•The relevance to symbiotic relationships of an embodied interaction within an immersive mixed-reality environment.•The User experience (UX) and learning performance while the user interacts with large datasets within an immersive, adaptive environment and while the system was equipped with sensing technologies to compute the user’s psychophysiological state.•The use of a subliminal technique to bias the user’s selection behavior in a 3D virtual environment.The work starts with an overview of theoretical efforts on symbiotic systems, from the origin of the idea (Licklider, 1960) to the more recent definitions informed by the recent advances in technology. After a review of research testifying the recent renewed interest in the topic, the work continues offering a discussion about theoretical contributions from other frameworks to the symbiotic systems theory. In particular, contributions from Telepresence, Persuasive technologies, Embodied interaction, Affective and Physiological computing have been considered and discussed.The first study aimed at measuring and comparing both UX and performance related to different ways to interact with virtual objects in a mixed-reality environment. In particular, we compared the most common way to input commands to a computer, that is, through the keyboard and mouse with an embodied interaction exploiting natural gestures and body movements. Results showed that, despite the performance (in term of task execution time) was greater with the keyboard and mouse, the UX was better with the embodied interaction system.The second study aimed at investigating the learning performance and the UX during the interaction with a neuroscience dataset within a mixed-reality environment. Important, the system was endowed with wearable sensing technology to compute the psy-chophysiological state of the user during his/her interaction. The purpose was to make the system adaptive, namely, capable to perform in real time some adjustments of information displayed according to the user’s state in order to support his/her task. Results showed that the system was able to facilitate the user’s task, leading to better learning performance and UX.The third study aimed at investigating the efficacy of the subliminal cueing in biasing the participants’ selection behavior in a forced-choice task between objects in a 3D virtual environment (VE) representing a realistic scenario. Results showed a significant effect of subliminal cueing on the selection behavior demonstrating the feasibility of subliminal cueing in VEs. The results also highlighted some peculiar characteristics of the subliminal cueing, like the short duration of its effect. These findings are relevant and suitable to inform the design of novel interfaces that exploit subliminal stimuli as an additional communication channel between the computer and the user. In the conclusion the results of the studies are discussed and evaluated." @default.
