The Relationship

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.

Michael Takeo Magruder, visual artist and researcher, discusses his digital and new media art and practice with Jeremy Pilcher, lawyer and academic, whose research engages with the intersection of art and law. Takeo's work asks viewers to question their relationship both to and within the real-time data flows generated by emerging technologies and the implications these have for archives. His art concerns the way institutions use such systems to create narratives that structure societies. This conversation discusses how Takeo's practice invites us, as individuals, to critically reflect on the implications of the stories that are both told to and about us by using gathered and distributed data.

The Relationship

Background: While investigating the real-time impedance at acupuncture points (acupoints), it was found that regular sinusoidal waves were present that corresponded to the pulsing of certain organs, such as respiration and duodenal waves, the stomach’s slow waves, and also the heart’s beating.Methods: This study investigated such respiration waves at lung-related acupoints to clarify their relation to the respiration pacesetter mechanism. The impedance at key acupoints was monitored in real time while the patients’ breathing slowed after exercise.Results: In all 7 patients studied, the respiration and heart-beat waves matched the rates in the corresponding organs at rest, and did not vary markedly due to exercise. In 3 of the 7 patients, their post-exercise respiration rate exactly matched that of their duodenal waves, but then dropped, stepwise, back to their usual respiration rate. In the other 4 patients, their post-exercise respiration rate did not reach that of their duodenal waves, so this pattern was not triggered.Conclusion: The results suggested that as well as the brainstem respiration pacesetter, there was also a separate “pace signal” present which remained constant and seemed to define the respiration rate when at rest. It is currently unknown what mechanism causes the respiration rate to increase due to exercise. But these results suggest that the brainstem pacesetter is sometimes guided by the duodenal pace signal instead of the lung pace signal, which may explain how the pacesetter is able to jump to a higher rate, even though its chemoreceptor inputs may be unchanged.

Empirical Illustration

We propose a new definition of learning potential as an emergent phenomenon. It emerges in the process of creating a unique scaffolding situation through the real-time interaction between teacher and child. We provide a model for analyzing the behavioral sequences within these scaffolding dynamics and illustrate it with the data of two qualitatively representative children working on a curriculum-related task with their teacher. It is hypothesized that if the dyads truly create their own dynamic scaffolding–related situation as presented in the model, they are expected to differ in terms of their temporal patterns in a nontrivial way. Analyses showed significantly different patterns for both dyads. We conclude that, in applied settings, an analysis of the dynamic patterns of scaffolding creation might provide important information about learning potential, in addition to information obtained with standardized dynamic tests.

The Relationship

In this paper, the real-time joint stiffness configuration strategy of a series parallel hybrid 7-DOF (degree of freedom) humanoid manipulator with flexible joints in continuous motion is studied. Firstly, considering the potential human robot accidental collision, combined with the manipulator safety index (MSI) and human body injury thresholds, the motion speed and joint stiffness of the robot are optimized in advance. Secondly, using hyperbolic tangent function for reference, the relationship between joint torques and passive joint deflection angles of the robot is given, which is beneficial for the real-time calculation of joint stiffness and obtain reasonable joint stiffness. Then, the structural model of the selected humanoid manipulator is described, on this basis, the relationship between the joint space stiffness and the Cartesian space stiffness of the humanoid manipulator is analyzed through Jacobian matrix, and the results show that the posture and joint space stiffness of the humanoid manipulator directly affect the Cartesian space stiffness of the humanoid manipulator. Finally, according to whether the humanoid manipulator works in the human-robot interaction environment, the real-time joint stiffness configuration of the humanoid manipulator in continuous motion is simulated and analyzed. The research shows that the humanoid manipulator with flexible joints can adjust the joint stiffness in real-time during continuous motion, and the joint stiffness configuration strategy can effectively improve the safety of human body in human-robot collision. In addition, in application, when the joint space stiffness of the robot is lower, the position accuracy can be improved by trajectory compensation.

<p>Architectural visualisation is often viewed with a degree of hesitancy by the architectural profession, for a perceived lack of criticality in the methods and outputs – particularly with the rise of hyper-real still imagery production. However, photography too suffers from a certain disconnect from an authentic experience of space, which we experience through our moving within it, our sensory gamut stimulated by the atmosphere memorable architecture possesses. This atmosphere is a holistic assemblage of design decisions made by the building designer, connected to mass, light, materiality, sound, among others. The field of gaming has been able to deploy many of these characteristics in virtual space for decades in some manner, and the tools used have been refined to the point where they are technically, and fiscally accessible to architecture.  This thesis proposes that real-time virtual engines, as used by game designers, can extend the field of architectural representation and design, by better conveying a sense of architectural atmosphere and providing increased immersion in virtual space compared to traditional techniques. It first seeks to define what architectural atmosphere may be recognised as, and how it may be caused to manifest, and then applies these findings to virtual space as a means to test the relationship between the real and unreal. Further to this, it applies this methodology to an iterative design process of both an architectural and virtual nature, with a final output that demonstrates the result of both concurrently.</p>
