Head In Space : A Head-Tracking Based Binaural Spatialization System, Luca A. Ludovico, Davide Andrea Mauro Phd, Dario Pizzamiglio
Davide Andrea Mauro
This paper discusses a system capable of detecting the position of the listener through a head-tracking system and rendering a 3D audio environment by binaural spatialization. Head tracking is performed through face recognition algorithms which use a standard webcam, and the result is presented over headphones, like in other typical binaural applications. With this system users can choose an audio file to play, provide a virtual position for the source in an euclidean space, and then listen to the sound as if it is coming from that position. If they move their head, the signal provided by the system changes …
Interdisciplinary Translation Of Comparative Visualization, James Birt, Dirk Hovorka, Jonathan Nelson
Interdisciplinary Translation Of Comparative Visualization, James Birt, Dirk Hovorka, Jonathan Nelson
James Birt
Spatial visualisation skills and interpretations are critical in the design professions, but traditionally difficult to effectively teach. Visualization and multimedia presentation studies show positive improvements in learner outcomes for specific learning domains. But the development and translation of a comparative visualization pedagogy between disciplines is poorly understood. This research seeks to identify an approach to developing comparable multimodal and interactive visualizations and attendant student reflections for curriculum designers in courses that can utilize visualizations and manipulations. Results from previous use of comparative multimodal visualization pedagogy in a multimedia 3D modelling class are used as a guide to translation of pedagogy …
Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka
Towards A Pedagogy Of Comparative Visualization In 3d Design Disciplines, James Birt, Jonathan Nelson, Dirk Hovorka
Jonathan J Nelson
Spatial visualization and interpretation are important skills for designers. However, these skills generally require significant experiential development over the course of years. Visualizations allow the human brain to convey complex spatial concepts in intuitive, navigable and manipulable forms improving learner outcomes and perceptions. But often these visualizations are studied as single modality solutions. Dual modality and multimedia presentation studies show positive improvements in learner outcomes but dual modality is often difficult to compare. This paper presents ongoing research in the use of comparative multimodal visualizations produced with emerging technology solutions in 3D Design classrooms. Presented are previous findings from multimedia …

We present a tele-immersive system that enables people to interact with each other in a virtual world using body gestures in addition to verbal communication. Beyond the obvious applications, including general online conversations and gaming, we hypothesize that our proposed system would be particularly beneficial to education by offering rich visual contents and interactivity. One distinct feature is the integration of egocentric pose recognition that allows participants to use their gestures to demonstrate and manipulate virtual objects simultaneously. This functionality enables the instructor to effectively and efficiently explain and illustrate complex concepts or sophisticated problems in an intuitive manner. The …
