Graduate Thesis by Matthew Schlueb submitted for a Master in Architecture from Pratt Institute (1994), under the direction of Richard Scherr (M. Arch. Chair & Major Advisor), Deborah Gans (B. Arch. Chair & Major Advisor), Martin Skalski (Industrial Design Advisor), Architecture faculty John Johansen, Raimund Abraham, Giuliano Fiorenzoli, Livio Dimitriu, William Katavolos, Vito Acconci, James Rossant, Haresh Lalvani, John Lobel, Theoharis David, and Design faculty William Fogler and William Fasolino. An investigative research study into the visual perception of architectural space, exploring proxemic relationships between the inhabitant and inhabitable form. The research revealed the influence 'form articulation and spatial delineation' has on human behavior, establishing the ability to measure the location and extremes of perceptual envelopes and thresholds, and an analysis of human subconscious and foreconscious processes within the theory of Gestalt Psychology. An independent study within the Industrial Design department as thesis research isolated the movement of gesture in form on perceived envelopes and thresholds of activated space, through a comparative modeling technique in refining adjustments of an original prototype toward an improved unified condition.
