Adaptive Model for Biofeedback Data Flows Management in the Design of Interactive Immersive Environments

Abstract

The interactivity of an immersive environment comes up from the relationship that is established between the user and the system. This relationship results in a set of data exchanges between human and technological actors. The real-time biofeedback devices allow to collect in real time the biodata generated by the user during the exhibition. The analysis, processing and conversion of these biodata into multimodal data allows to relate the stimuli with the emotions they trigger. This work describes an adaptive model for biofeedback data flows management used in the design of interactive immersive systems. The use of an affective algorithm allows to identify the types of emotions felt by the user and the respective intensities. The mapping between stimuli and emotions creates a set of biodata that can be used as elements of interaction that will readjust the stimuli generated by the system. The real-time interaction generated by the evolution of the user’s emotional state and the stimuli generated by the system allows him to adapt attitudes and behaviors to the situations he faces.

Interactive virtual reality environments and emotions: a systematic review

“…VR is distinguished by being: (a) immersive, allowing users to immerse themselves in a virtual environment and experience the sensation of being in another place, thanks to various elements such as visual quality, plot and auditory design; (b) interactive, providing the possibility to interact with virtual elements, exposing the user to various stimuli that produce a user response; (c) imaginative, i.e., the ability to create imaginary worlds that replicate the real world, encouraging creativity (Gomes et al, 2021;Lin et al, 2020).…”

“…For the above reasons, exposure to immersive environments creates experiences that can provoke a variety of emotions at different levels of intensity. These emotions are generated thanks to the sense of realism and presence that surrounds the user while immersed in the experience (Gomes et al, 2021;Pavic et al, 2023).…”

The Influence of Brain Activity on the Interactive Process through Biofeedback Mechanisms in Virtual Reality Environments

“…The introduction of biofeedback systems in the design of a simple immersive environment transform it into an Emotionally Adaptive Immersive Environment, where the user experience can be optimized through the continuously adaptation of stimuli to the user emotional state. The quantity and intensity of the stimuli are determined through an adaptive affective algorithm, which collect, interpret, and convert the user's physiological data [5].…”

Virtual Reality Cognitive-Behavioral Therapy Biofeedback System for Glossophobia

“…Regarding biological sensors, two different sensors were chosen, one for electroencephalogram (EEG) and another for heart rate. In terms of EEG, the author opted for the Looxid Link device because it is an extension of the HTC Vive Pro, fully integrating its operation, this device records EEG of the frontal lobes and allows to detect fluctuations in the user's attention and relaxation levels (Veloso Gomes, et al, 2021). In the case of heart rate, the Bitalino device was chosen because it allows the collection of various biological signals, it can also connect remotely with other devices through Bluetooth technology.…”
