Projected visual cues for guiding physical movement
First Claim
Patent Images
1. A method of guiding physical movement of a human subject, the method comprising:
- observing, via one or more cameras, a physical environment;
identifying, with a computing device configured to process image data from the camera, a current three-dimensional position of a body portion of a human subject within the physical environment;
obtaining, with the computing device, a model path of future travel for the body portion of the human subject; and
projecting, via an image projector, a visual cue onto the human subject at the current three-dimensional position of the body portion, the visual cue indicating the model path of future travel for the body portion of the human subject.

Abstract
Physical movement of a human subject may be guided by a visual cue. A physical environment may be observed to identify a current position of a body portion of the human subject. A model path of travel may be obtained for the body portion of the human subject. The visual cue may be projected onto the human subject and/or into a field of view of the human subject. The visual cue may indicate the model path of travel for the body portion of the human subject.

14. A computer comprising:
-
a depth-camera input to receive depth-camera information from a depth camera; an image-projector output to send projector information to an image projector; a processor operatively connected to the depth-camera input and to the image-projector output; a storage device holding instructions executable by the processor to; identify, from the depth-camera information, a current three-dimensional position of a body portion of a human subject imaged by the depth camera; obtain a model path of future travel for the body portion of the human subject; and project a visual cue via the image projector onto the human subject at the current three-dimensional position, the visual cue indicating the model path of future travel for the body portion of the human subject. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method of guiding physical movement of a human subject, the method comprising:
-
identifying, with a computing device configured to process image data from a camera, a current three-dimensional position of a body portion of a human subject within a physical environment; obtaining a multi-dimensional model path of future travel for the body portion of the human subject; and projecting a visual cue onto the body portion at the current three-dimensional position via one or more image projectors, the visual cue including; a visible light portion that indicates a first direction of movement for the body portion toward or along the model path of future travel in a first plane, and a directional indicator that indicates a second direction of movement for the body portion toward or along the model path of future travel perpendicular to the first plane.
