    From the observatory to the classroom: space images in the keystone “600 SET” and “1200 SET”
    (Edições Universitárias Lusófonas, 2017) Pérez Gonzalez, Carmen; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    This paper introduces the astronomical images of the Keystone 600 SET and 1200 SET, and the original photographic plates from which they were printed, analysing both the photographic plate and the published card. The astronomer's work will be discussed together with the method of achieving the stereoscopic effect for the different celestial bodies. Of particular interest was the method of taking advantage of the lunar libration for producing Moon stereographs used by British amateur astronomer Warren de la Rue (1815-1889). He was a pioneer who both established and used this method as early as the 1850s. In addition, this study will also explore the method used decades later on by Edward Emerson Barnard (1857-1923), and other astronomers working at the Yerkes Observatory, to produce stereographs of other celestial bodies. Analysis of how Keystone and other companies enabled a democratization of astronomical portraiture will also be performed and can be attributed to the inclusion of astronomical images in their educational set of stereographs, which were used as leading visual tools to help students learn about our earth and its neighbours.

    The quest for stereoscopic movement: was the first film ever in 3-D?
    (Edições Universitárias Lusófonas, 2017) Pellerin, Denis; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    Histories of the cinema mention the Lumière brothers and sometimes Louis Le Prince as the precursors of the moving pictures but they usually forget the important part played by Antoine Claudet, Louis Jules Duboscq, Charles Wheatstone and Joseph Plateau. Barely a year after the introduction of the lenticular stereoscope, these polymaths managed to create what can not only be considered as the first "movie" ever but also happens to be in 3-D!

    The virtual concert hall : a research tool for the experimental investigation of audiovisual room perception
    (Edições Universitárias Lusófonas, 2017) Maempel, Hans-Joachim; Horn, Michael; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    The Virtual Concert Hall is a virtual environment that has been specifically designed for the optoacoustic simulation of performance rooms. As a tool for experimental research, its design is derived from particular methodological demands including harvesting comparable acoustical and optical information, dissociating the space and content of multisensory events,varying optical and acoustical room properties in a mutually independent manner, while also providing a full set of stimulus cues. The system features 3D sound and vision by applying dynamic inaural synthesis and a 161°stereoscopic projection on a cylindrical screen. Room simulation data were acquired in situ in the form of orientational binaural room impulse responses and stereoscopic panoramic images. Music and speech performances were recorded acoustically in an anechoic room and optically in a greenbox studio and inserted into the virtual rooms. The Virtual Concert Hall provides nearly all perceptually relevant acoustical and optical cues, enabling experiments on the audiovisual perception of optoacoustically conflicting rooms under rich-cue conditions.
