METHOD AND SYSTEM FOR REDUCING MOTION BLUR WHEN EXPERIENCING VIRTUAL OR AUGMENTED REALITY ENVIRONMENTS
First Claim
1. A system for reducing motion blur experienced by participants viewing virtual and augmented reality content on one or more displays, the system comprising:
- a. a first optical arrangement comprising a first lens and a second lens wherein the first lens and second lens are optically aligned, wherein the first optical arrangement is configured to allow a participant to view a display through the first optical arrangement, and wherein the second lens comprises a first surface and a second surface;
b. a first active shutter system positioned in the first optical arrangement between the first lens and the first edge of the second lens and configured to substantially block the participant'"'"'s view of the display when the first active shutter system is activated; and
c. shutter control and processing components coupled to the first active shutter system and programmed to drive the first active shutter system.

Abstract
A system or apparatus for reducing motion blur includes an active shutter system, shutter control and processing components, an optional optical sensor, one or more optional movement sensors, and a power source, and can cooperate with a virtual or augmented reality system and display. The shutter system is optimally positioned between a user and the display so that one or more shutters of the system can be activated to block a user'"'"'s view of the display. The shutter system is activated to block refresh lines or other artifacts present when the display refreshes. The shutter system also can be activated according to movement of the user. The shutter system can be one or more independent shutters and each shutter can have one or more shutter segments. Additionally, the shutter system can include multiple cooperating layers of shutters. The shutter system further can be incorporated in a multi-lens optical system.
