Augmenting the Field-of-View of Head-Mounted Displays with Sparse Peripheral Displays
summary
Proposes a low-cost way to expand headset FOV to about 170–190° using a sparse LED ring rather than heavy optics, with two prototypes: SparseLightVR (Oculus DK2 plus 70 LEDs, Delrin diffuser) and SparseLightAR (Galaxy S6–based AR with 112 LEDs and paper diffuser). Uses Unity + Oculus SDK, per-LED color via Voronoi averaging in CIELAB, updates >75 Hz. User studies show faster target acquisition and that a countervection visualization often reduces nausea compared with no periphery.
