A hybrid projection to widen the vertical field of view with large screens to improve the perception of personal space in architectural project review

In this paper, we suggest using a hybrid projection to increase the vertical geometric field of view without incurring large deformations to preserve distance perception and to allow the seeing of the surrounding ground. We have conducted an experiment in furnished and unfurnished houses to evaluate the perception of distances and the spatial comprehension. Results show that the hybrid projection improves the perception of surrounding ground which leads to an improvement in the spatial comprehension. Moreover, it preserves the perception of distances and sizes by providing a performance similar to the perspective one in the task of distance estimation.
