SPE selection technique: A projection-based approach for precise object interaction in immersive virtual environments

Selecting objects has always represented one of the fundamental tasks required by the majority of immersive applications. Despite the key role played by selection techniques in the design of immersive experiences, there is not a dominant or a one-size-fits-all approach yet. In this scenario, the current paper proposes a novel selection technique, named Selection among Projected Elements, which focuses on the selection of distant, small and possibly close, objects. The devised approach was assessed in the context of a virtual heritage application that was specifically designed with the aim of stressing the capabilities of the SPE technique.
