Systems and methods for real-time winding analysis for knot detection |
摘要 |
Embodiments of systems, methods, and computer-readable media for real-time winding analysis for knot detection are disclosed. For example, one embodiment of the present invention includes a method having the steps of receiving a first wrapping signal indicating a first wrapping of the simulated thread around a second tool to create a first loop. The method further includes determining a first wrapping direction based at least in part on the first wrapping signal; receiving a first tightening signal indicating a pulling of a first end of the simulated thread through the first loop; determining a first half-hitch based at least in part on the first winding direction and the first tightening signal; and outputting the first half-hitch. In another embodiment, a computer-readable media includes code for a carrying out such a method. |

1. A method, comprising:
receiving, by a processor, a first wrapping signal from a sensor in communication with a tool, the tool comprising an actuator, the first wrapping signal indicating a first wrapping of a simulated thread around the tool to create a first loop; determining, by a processor, a wrap angle based at least in part on a plurality of normal vectors along a portion of the simulated thread, the plurality of normal vectors based at least in part on the wrapping signal; determining, by a processor, a first winding direction based at least in part on the wrap angle; receiving, by a processor, a first tightening signal indicating a pulling of a first end of the simulated thread through the first loop; determining, by a processor, a first half-hitch based at least in part on the first winding direction and the first tightening signal; and outputting, by a processor, the first half-hitch and an actuator signal configured to cause the actuator to output a haptic effect. |
