Geosimulation model using geographic automata for simulating land-use patterns in urban partitions

金沢大学理工研究域環境デザイン学系Cellular automata (CA) are an effective means of urban-growth simulation. Moreover, the development of a planning support system associated with the theory of artificial intelligence has recently become a new global challenge. In this paper we investigate a geosimulation model using CA based on the geographic information system (GIS) for visualising land-use patterns in urban partitions. Most recent simulation models using CA have been developed in regular grid nets or networks, where adjacent grids or networks in urban space are easily addressed. Our project explores how to utilise an irregular polygon dataset in a GIS database in order to deal with spatial microsimulation. A new concept used in this project takes into account the effects of urban planning, such as land-use zoning and street networks, at the level of parcels and blocks in urban space. Adjacent irregular parcels on both sides of a street are intended targets in the simulation. In this paper, a method of simulating land-use patterns in urban space after the implementation of land-readjustment projects is discussed

The effects of the size and weight of a mobile device on an educational game

In this paper, we present an educational game for an iPhone and a Tablet PC. The main objective of the game was to reinforce children's knowledge about the water cycle. The game included different interaction forms like the touch screen and the accelerometer and combined AR mini-games with non-AR mini-games for better gameplay immersion. The main differences between the two devices were screen size and weight. A comparative study to check how these differences affect different aspects was carried out. Seventy-nine children from 8 to 10 years old participated in the study. From the results, we observed that the different characteristics (screen size and weight) of the devices did not influence the children's acquired knowledge, engagement, satisfaction, ease of use, or AR experience. There was only a statistically significant difference for the global score in which the iPhone was scored higher.We would like to highlight that the scores for the two devices and for all the questions were very high with means of over 4 (on a scale from 1 to 5). These positive results suggest that games of this kind could be appropriate educational games and that the mobile device used may not be a decisive factor. (C)2012 Elsevier Ltd.

Handheld Augmented Reality in education

[ES] En esta tesis llevamos a cabo una investigación en Realidad Aumentada (AR) orientada a entornos de aprendizaje, donde la interacción con los estudiantes se realiza con dispositivos de mano. A través de tres estudios exploramos las respuestas en el aprendizaje que se pueden obtener usando AR en dispositivos de mano, en un juego que desarrollamos para niños. Exploramos la influencia de AR en Entornos de Aprendizaje de Realidad Virtual (VRLE) y las ventajas que pueden aportar, así como sus límites. También probamos el juego en dos dispositivos de mano distintos (un smartphone y un Tablet PC) y presentamos las conclusiones comparándolos en torno a la satisfación y la interacción. Finalmente, comparamos interfaces táctiles y tangibles en aplicaciones de AR para niños bajo una perspectiva en Interacción Hombre-Máquina.[EN] In this thesis we conduct a research in Augmented Reality (AR) aimed to learning environments, where the interaction with the students is carried out using handheld devices. Through three studies we explore the learning outcomes that can be obtained using handheld AR in a game that we developed for children. We explored the influence of AR in Virtual Reality Learning Environments (VRLE) and the advantages that can involve, as well as the limits. We also tested the game in two different handheld devices (a smartphone and a Tablet PC) and present the conclusions comparing them concerning satisfaction and interaction. Finally, we compare the use tactile and tangible user interfaces in AR applications for children under a Human-Computer Interaction perspective.González Gancedo, S. (2012).
