Creating ergonomic manikin postures and controlling computer-aided design environments using natural user interfaces

摘要

A computer receives a set of spatial coordinates from a motion-sensing input device, the spatial coordinates describing a position of at least one joint of a limb of a human model. The computer sends the set of spatial coordinates to a computer-aided design application, the computer-aided design application representing movements of the ergonomic manikin based on changes in limb angles described by a plurality of instances of angle data. The computer receives angle specifications from a computer-aided design application, the angle specifications corresponding to an angle of the limb in at least one three-dimensional plane. The computer converts the set of spatial coordinates to angle data in accordance with the received angle specifications, the angle data describing positioning of the limb.

主权项

1. An apparatus for positioning structural models and controlling their design environments, comprising:
a processor; a memory in communication with the processor; a motion-sensing input device, in communication with the processor, and configured to track a motion of an object and to generate sets of spatial coordinate data for at least one point located on the object, wherein the object is an ergonomic manikin; and an application stored in the memory, wherein when the application is executed by the processor the application is configured to:
receive a first set of spatial coordinate data for the at least one point from the motion-sensing input device; andsend spatial coordinate data to a computer-aided design system, the computer-aided design system computing angle data to update a design of a model of the object based on the motion of the point located on the object, wherein the processor executes a plurality of algorithms that integrate the motion-sensing input device with the computer-aided design system to enable use of a combination of voice commands and body motions, and wherein the voice commands toggle the application between using the body motions to perform skeletal tracking to control the object and using the body motions to move a cursor in a workbench environment of the computer-aided design system to perform functions comprising at least one of pan, zoom, and rotate a perspective view in the workbench environment.
