Systems and methods to provide an interactive space over an expanded field-of-view with focal distance tuning

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.

Description

FIELD OF THE INVENTION[0001]The systems and methods described herein relate to providing an interactive space, such as an augmented reality environment and / or a virtual reality environment, over an expanded field-of-view and further including a feature of focal distance tuning.BACKGROUND OF THE INVENTION[0002]There are many types of vision systems that provide virtual and / or augmented reality (AR) displays. In particular, wearable technology such as head mounted displays (HMD) are becoming more popular. Currently, some AR displays have a limited field-of-view, resulting in a less immersive interactive experience for the user.SUMMARY[0003]One or more implementations of the systems and methods described herein may be configured to provide an interactive space over an expanded field-of-view with focal distance tuning. Vergence movements of the eye may be closely connected to accommodation of the eye. Vergence may refer to the simultaneous movement of both eyes in opposite directions, a...

AI Technical Summary

Benefits of technology

[0003]One or more implementations of the systems and methods described herein may be configured to provide an interactive space over an expanded field-of-view with focal distance tuning. Vergence movements of the eye may be closely connected to accommodation of the eye. Vergence may refer to the simultaneous movement of both eyes in opposite directions, and / or the movement of one eye in relation to the other, to obtain and / or maintain single binocular vision. Accommodation may refer to the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies. This may include the automatic adjustment of the eye for seeing at different distances effected by changes in the convexity of the crystalline lens. In some stereoscopic display devices and systems, such as those presented herein, an image presented to a user may be focused at a fixed focal distance (or depth) away from the eye, while the perceived distance (or depth) of the virtual content formed by the images may vary. The differences in those distances may require the viewer to uncouple vergence and accommodation. The uncoupling of vergence and accommodation required by stereoscopic displays may reduce one's ability to fuse the binocular stimulus and may cause discomfort and / or fatigue for the viewer. This problem may be referred to as the “vergence-accommodation conflict.” One or more implementations of the system presented herein may be configured to solve this problem and / or other problems. By way of non-limiting illustration, a set of tuning components may be configured to adjust (e.g., tune) the focal distance of images forming virtual content to match, or substantially match, the vergence distance, therefore increasing the ease of use and comfort of an optical system.

Problems solved by technology

Currently, some AR displays have a limited field-of-view, resulting in a less immersive interactive experience for the user.

The uncoupling of vergence and accommodation required by stereoscopic displays may reduce one's ability to fuse the binocular stimulus and may cause discomfort and / or fatigue for the viewer.
