Abstract

Systems and methods to provide an interactive space over an expanded field-of-view with focal distance tuning are presented herein. The system may include one or more of a headset, a first image forming component, a second image forming component, a set of tuning components, one or more physical processors, and/or other components. The first image forming component may be configured to generate light rays to form a first set of images presented over a first angular portion of a user's field-of-view. The second image forming component may be configured to generate light rays to form a second set of images of virtual content presented over a second angular portion of the user's field-of-view. A vergence distance of a gaze of a user may be determined. A focal distance of the images may be adjusted to match the vergence distance.
