Computer Interface for Remotely Controlled Objects and Wearable Articles with Absolute Pose Detection Component

摘要

A remotely controlled object (e.g., an aircraft) or a wearable article (e.g., virtual or augmented reality glasses) using high optical contrast features and a photodetector that detects light produced, reflected or scattered by the features and outputs data indicative thereof. The remotely controlled object or wearable article uses one or more controllers to determine its position and/or orientation in the real three-dimensional environment based on data from the photodetector. Data from one or more auxiliary motion sensing devices, e.g., a relative motion sensor such as an inertial device or other auxiliary motion device relying on acoustics, optics or electromagnetic waves within or outside the visible spectrum, can be used to supplement the position and/or orientation data from the photodetector.

主权项

1. A wearable article cooperating with a first plurality of high optical contrast features disposed in a real three-dimensional environment, said wearable article comprising:
a) a photodetector configured to detect said first plurality of high optical contrast features and generate photodetector data representative of the positions of said first plurality of high optical contrast features; and b) a controller configured to identify a derivative pattern of said first plurality of high optical contrast features from said photodetector data, wherein said derivative pattern is indicative of the position of said photodetector.
