METHOD AND SYSTEM FOR REDUCING MOTION BLUR WHEN EXPERIENCING VIRTUAL OR AUGMENTED REALITY ENVIRONMENTS

摘要

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.

主权项

1. A system useful for reducing motion blur when viewing content delivered on a cooperating display, the system comprising:
a. a first active shutter system configured to cooperate with a first display area and positioned such that can substantially block the participant's view of the first display area when the first active shutter system is activated; b. a second active shutter system configured to cooperate with a second display area and positioned such that can substantially block the participant's view of the second display area when the second active shutter system is activated; c. an optical sensor positioned near the cooperating display such that it can collect a sample of optical data when content is delivered on the display; and d. shutter control and processing components coupled to the active shutter system and in communication with the optical sensor, wherein the shutter control and processing components are programmed to:
i. receive from the optical sensor samples of optical data;ii. filter the optical sensor data sample to identify data that changes when the display refreshes;iii. calculate the refresh moment of the display;iv. calculate the refresh frequency of the display;v. calculate when the first display area refreshes and when the second display area refreshes according to the known location of the sensor, the refresh moment, and the refresh frequency;vi. activate the first active shutter system and deactivates the second active shutter system when the first display area is refreshing; andvii. activate the second active shutter system and deactivates the first active shutter system when the second display area is refreshing.
