Physically Based

To experience a real soap bubble show, materials and tools are required, as are skilled performers who produce the show. However, in a virtual space where spatial and temporal constraints do not exist, bubble art can be performed without real materials and tools to give a sense of immersion. For this, the realistic expression of soap bubbles is an interesting topic for virtual reality (VR). However, the current performance of VR soap bubbles is not satisfying the high expectations of users. Therefore, in this study, we propose a physically based approach for reproducing the shape of the bubble by calculating the measured parameters required for bubble modeling and the physical motion of bubbles. In addition, we applied the change in the flow of the surface of the soap bubble measured in practice to the VR rendering. To improve users’ VR experience, we propose that they should experience a bubble show in a VR HMD (Head Mounted Display) environment.

The Subject

The audible creaking of Glenn Gould’s loose-jointed piano chair has historically been the subject of apologetic liner notes and recording studio memoirs. These chair creaks are here recognized as “sounded movements” of Gould’s body. This article triangulates the score of Schoenberg’s Sechs kleine Klavierstücke, op. 19, no. 1, published analyses of its unique rhythmic unfolding, and new micro-temporal measurements of Gould’s September 1965 recording of the work. Quantifying Sanden’s concept of “corporeal liveness,” spectrographic tools are used to generate a proper census of all the sounds captured by the microphone in order to map their rhythmic interaction. A notable “creak gap” in Gould’s recording is linked to published observations regarding the work’s process of emerging metric clarity, and one of Gould’s vocal elaborations is recognized for its augmentation of Schoenberg’s pitch material. Overlaying analytical literature with microtiming data reveals a correlation between the composition’s trajectory of metric clarification and the decrease in Gould’s physical motion. The findings are used to question the pervasive and disturbing suppression of non-notated sounds that accompany the recording of notated music. Recognizing sounds that are normally marginalized, this study fuses theoretical observations about Schoenberg’s composition with the audio artifacts of Gould’s corporeality.

Momentum Integral

The force field described by a potential function of the form U = ?n k=1 ak/rk (r = distance between particles, ak = real parameters) models various concrete situations belonging to astronomy, physics, mechanics, astrodynamics, etc. The two-body problem is being tackled in such a field. The motion equations and the first integrals of energy and angular momentum are established. The McGehee-type coordinates are used to blow up the collision singularity and to paste the resulting manifold on the phase space. The flow on the collision manifold is depicted. Then, using the rotational symmetry of the problem and the angular momentum integral, the local flow near collision is described and interpreted in terms of physical motion.

This article provides evidence that motion has the ability to stably fuse two different colored ‘spatially separated’ stimuli without impairments against the shape of those separated stimuli. Based on our observations, dilated pupils promote colours fusion; and the optimal fusion happens when the stimuli are moving in opposite direction of the actual physical motion, namely, when there is illusory motion reversal. The previous observations suggested that retinal peripheries have main contributions on the present illusion which we called; motion induced colours fusion ‘MICF’ illusion.

Instruction And Learning

It is widely accepted that nonverbal communication is crucial for learning, but the exact functions of interpersonal coordination between instructors and learners remain unclear. Specifically, it is unknown what role instructional approaches play in the coupling of physical motion between instructors and learners, and crucially, how such instruction-mediated Body-to-Body Coupling (BtBC) might affect learning. We used a video-based, computer-vision Motion Energy Analysis (MEA) to quantify BtBC between learners and instructors who used two different instructional approaches to teach psychological concepts. BtBC was significantly greater when the instructor employed a scaffolding approach than when an explanation approach was used. The importance of instructional approach was further underscored by the fact that an increase in motion in the instructor was associated with boosted BtBC, but only during scaffolding; no such relationship between the instructor movements and BtBC was found during explanation interactions. Finally, leveraging machine learning approaches (i.e., support vector and logistic regression models), we demonstrated that both learning outcome and instructional approaches could be decoded based on BtBC. Collectively, these results show that the real-time interaction of teaching and learning bodies is important for learning and that instructional approach matters, with possible implications for both in-person and online learning.
