“…More recently, Wiener and Franz (2004), showed that jaggedness, a measure resulting from the relation between an isovist's area and its perimeter, is related to people's perception of interestingness. Finally, Peebles, et al (2007) showed that isovist characteristics, in particular drift, were related to people's assessment of their sense of orientation in maps.…”

This paper presents ongoing research on the use of agents equipped with "exomatic visual architecture" (Turner et al., 2001). The main objective was to test whether some rarely explored isovist measures, like drift and longest line of sight, are associated with aggregated movement patterns of downtown Santiago, Chile. To test this idea, a series of algorithms were created and compared with observed data recorded at approximately 200 points during an entire workday.The main results show that drift-based algorithms were better suited to predict aggregated patterns than random behavior, although the extent of such relation is still weak (r2 = 0.27). From a theoretical point of view, these results seem to be in accordance with current cognitive theories (Clark, 2009;Thompson, 2007) stressing the dynamic nature of human behavior.Keywords: pedestrian movement, drift-based movement, agents, vision. RESUMENEste artículo presenta una investigación en curso sobre el uso de agentes provistos de visión exomática (Turner et al 2001). El objetivo principal es evaluar si algunas medidas, raramente examinadas, como las isovistas: líneas de visión más extendida, están asociadas a flujos de movimiento existentes en el centro de Santiago de Chile. Para ello, se crearon una serie de algoritmos que guían a los agentes y se compararon con los flujos detectados en cerca de 200 puntos, durante un día hábil completo. Los resultados principales, mostraron que los algoritmos basados en el Drift fueron más efectivos en reproducir los flujos de movimientos, comparados con los algoritmos basados en un movimiento aleatorio de los agentes, aunque esta correlación es aún débil (r2 = 0,27). Desde un punto de vista teórico, estos resultados parecen estar en línea con las teorías de cognición contemporáneas (Clark, 2009;Thompson, 2007) que tienden a enfatizar la naturaleza dinámica del comportamiento humano.Palabras clave: movimiento peatonal, movimiento basado en Drift, agentes, visión.

“…self‐localization is a “more complex combined task […] which inevitably includes simultaneous orientation to some extent” (Peebles et al. , p. 391). Literature suggests that self‐localization is typically performed by “using local cues which are visible from our current location.…”

“…; Peebles et al. ), studies suggest that, “in geographically realistic contexts, visible salient landmarks bias people away from using optimal geometry‐matching strategies” (Davies and Peebles , p. 135). Achieving realism is one of the main goals of our experiments, therefore we focus in this article on orientation and self‐localization based on landmarks.…”

Self-localization is the process of identifying one's current position on a map, and it is a crucial part of any wayfinding process. During self-localization the wayfinder matches visually perceptible features of the environment, such as landmarks, with map symbols to constrain potential locations on the map. The success of this visual matching process constitutes an important factor for the success of self-localization. In this research we aim at observing the visual matching process between environment and map during self-localization with real-world mobile eye tracking. We report on one orientation and one selflocalization experiment, both in an outdoor urban environment. The gaze data collected during the experiments show that successful participants put significantly more visual attention to those symbols on the map that were helpful in the given situation than unsuccessful participants. A sequence analysis revealed that they also had significantly more switches of visual attention between map symbols and their corresponding landmarks in the environment, which suggests they were following a more effective selflocalization strategy.

A signal or a symbol has been sent with conscious. Urban space has signified elements like landmark. Landmarks as references signs orient the people. Landmarks are defined as an external point of reference that helps orienting in a familiar or an unfamiliar environment. This study is about to clear out the meaning of landmark for the city users who have perceived reference point with their memory and perception. In other words, this study is about discovering how the city affects the people who experience the urban space within semiotic of landmarks in Konya, Turkey. The method of this study is photo-elicitation to understand how people orient themselves in moving within urban space considering landmarks. Analysis of interview texts, there were six different type of landmarks as; city memory-historical, city landscape/ square, high rise/skyscraper, daily life/city usage, personal memory/personal perception, circulation pattern. In this study the semiology of communication studies codes established by society to produce messages consciously sent and received as signals, signs and symbols.
