In a situated simulation (sitsim) there is approximate identity between the user's visual perception of the real physical environment and the user's visual perspective into a 3D graphics environment as it is represented on the screen. The relative congruity between the real and the virtual perspectives is obtained by letting the camera position and movement in the 3D environment be conditioned by the positioning and orientation hardware. As the user moves in real space the perspective inside the 3D graphic environment changes accordingly. A situated simulation requires a smartphone/tablet with good graphics capabilities, GPS-positioning, accelerometer, electronic compass and gyroscope.
A sitsim is closely related to mixed and augmented reality. While mixed reality is characterized by different combinations of virtual and real representations along the reality-virtuality continuum, a situated simulation is a 'clean screen' solution where there is a distinct (although minor) difference between the virtual (audio–visual) perspective via the device and the real perspective of the user. This approach has also been named 'Indirect Augmented Reality'.
The development is conducted in close collaboration with Tomas Stenarson at CodeGrind AB and Šarūnas Ledas at Tag of Joy, Elpida Hadjidaki (Phalasarna Association) Larry Friedlander (Stanford University), Terje Rasmussen (University of Oslo), Andrew Morrison (AHO) and Ole Smørdal (UiO). The research has been funded by the VERDIKT-programme (The INVENTIO-project) and the KLIMAFORSK-programme (The ClimSim-preproject), Norwegian Research Council; EngageLab at University of Oslo; Dept. of Media & Communication, University of Oslo; Norway Opening Universities; Arts Council Norway (ABM-utvikling); and Oslo Science Park (Forskningsparken).
…Sitsim Apps (free)
'Phalasarna' (v. 1.1) is now available for iOS.
'Roman Forum’ (v. 1.2) is available for download on both iOS and Android!
'Nytt Museum' (v. 2.0) download iOS and (v. 1.0) Android!
