TY - RPRT A1 - Vogel, Peter T1 - Investieren unter Nebenbedingungen - Teil 4: Ergänzung zu Teil 3 N2 - Der vierte Teil der Schriftenreihe "Trading" präsentiert eine statistische Auswertung von Kursdaten bei einer Haltefrist von einem Handelstag. Die Statistik beinhaltet Gewinnfaktor bzw. Rendite und Investitionsgrad aus Teil 1 sowie Volatilität, Chance, Risiko und Handelskosten, welche in Teil 3 eingeführt wurden. Kaufbedingungen werden wie in Teil 1 mit Hilfe des Kursverhältnisses an zwei aufeinander folgenden Handelstagen gebildet. Die Auswertung für den Markt FEBRDUSA_1 historischer Kursdaten liefert eine in sich schlüssige Beschreibung des Einflussfaktors Kaufbedingung auf die künftige Kursentwicklung. Den größten Gewinn liefert eine Mean Reversion-Strategie, bei der die Chance deutlich über dem Risiko liegt. Da die Statistik die Begrenzung eingegangener Neuinvestitionen berücksichtigt, werden Übertreibungen vermieden, die einer arithmetischen Mittelwertbildung anhaften. Die statische Auswertung für einen mit Random Walks gebildeten Markt bestätigt, dass für diesen Fall keine Abhängigkeit von der Kaufbedingung besteht. N2 - The fourth part of the series "Trading" presents experimental findings of price data statistics for a holding period of one day. The statistics include gain factor, return and investment ratio of part 1 as well as volatility, chance, risk and trading costs of part 3. Buy conditions are defined by means of the price relationship for two subsequent trading days, as in part 1. The experimental findings for the market FEBRDUSA_1 of historical price data provides a coherent description of the influence of the buy condition on future prices. The maximum return is provided by a buy condition describing a price slump. Since the statistics incorporates the limited amount of new investments, exaggeration due to arithmetic averaging is avoided. The experimental findings for a market of random walks confirm that there is no dependence on the buy condition in this case.

Users can collaborate through realtime audio, video, and drawings in a virtual space. The developed system was tested in a preliminary user study, which confirmed an increase in spatial and situational awareness among viewers as well as reduction in cognitive workload. Believing that our system provides a novel style of collaboration in mixed reality environments, we discuss future applications and extensions of our prototype.

Thus, we argue that, on a perceptual level, reverberation basically breaks down into interaural differences and spectro-temporal cues and that the separation of a perceived timbre into a sound source and a surrounding room is a purely cognitive process. To investigate the connection between the perception of reverberation cues and timbre analysis, the sensitivity for changes in reverberation was compared to timbre perception abilities. The Timbre Perception Test was used to measure the perception of the temporal envelope, spectral centroid, and spectral flux of artificial sounds. Sensitivity for changes in reverberation time was tested with a discrimination task using speech and noise with speech-alike spectral and temporal envelopes as source signals. Musical and acoustical expertise was assessed through the Goldsmiths Musical Sophistication Index and self-reports on experience with and knowledge of acoustics. There was a considerable correlation between timbre and reverberance perception ability, but timbre perception and academic experience predicted only 41% of the variance in reverberance perception. Still, perception abilities related to similar acoustical phenomena seem to be better indicators of listening skills than self-reports on acoustical or musical expertise.

In a virtual (tv) studio talents could be overburden by interaction tasks because camera and text require extensive attention. We take a look into animations and inter- actions within a studio, which do not require any special attention or learning. We show the generation of an artificial shadow from a talent, which ease the keying process, where separation of real shadows from the background is a difficult task. We also demonstrate animations of footsteps and dust. Furthermore, capturing talents’ height can also be used to adjust the parameters of elements in the virtual environment, like the position and scaling of a virtual display. In addition to the talents, a rigid body was tracked as placeholder for graphics, easing the interaction tasks for a talent. Two test productions show the possibilities, which subtle animations offer. In the second production, the rendering was improved (shadows, filtering, normal maps, ...) and instead of using the rigid body to move an object (a flag), the animation was only controlled by the hand’s position.
