Abstract

A monitor device includes a memory, a hardware mount configured to attach to a rigging member, a motion sensor configured to detect a first motion characteristic of the rigging member, and a processor operatively coupled to the memory and to the motion sensor. The processor is configured to receive the first motion characteristic from the motion sensor. The processor is further configured to send the first motion characteristic to a controller. The controller is configured to receive a second motion characteristic generate an output for a display based on the first motion characteristic and the second motion characteristic.

Claims

1. A system, comprising:

a monitor device being configured to couple to a rigging member, the monitor device being configured to measure motion of the rigging member;

a controller operatively coupled to the monitor device, the controller being configured to;

receive first motion data from the monitor device coupled to the rigging member and second motion data from the monitor device;

compute a first force that corresponds to the first motion data and a second force that corresponds to the second motion data;

compute a 3D vector based on the first force and the second force;

decompose the 3D vector into at least a first direction-based component vector value;

compare a magnitude of the first direction-based component vector value with a magnitude of a previous vector value to identify a change in force on a subject; and

update a graphical user interface of a display device based on the change in force on the subject.

2. The system of claim 1, wherein the controller is configured to periodically receive the first motion data and second motion data from the monitor device at least once every five seconds.

3. The system of claim 1, wherein the controller is configured to periodically receive the first motion data and the second motion data from the monitor device at least twice every second.

4. The system of claim 1, wherein the first force corresponds to a first tension in the rigging member, and wherein the second force corresponds to a second tension in the rigging member.

5. The system of claim 1, wherein the 3D vector is computed based on geometry or a material of the subject, or the rigging member.

6. The system of claim 1, wherein when decomposing the 3D vector into at least the first direction-based component vector value, the controller is configured to decompose the 3D vector into three components.

7. The system of claim 1, wherein when comparing the magnitude of the first vector value with the previous vector value to identify the change in force on the subject, the controller is configured to compare a current magnitude of a current parallel component to a previous magnitude of a previous parallel component, wherein an increase in magnitude of the parallel component is indicative of an increase in a driving force on the subject.

8. The system of claim 1, wherein when comparing the magnitude of the first vector value with the previous vector value to identify the change in force on the subject, the controller is configured to compare a current magnitude of a current perpendicular component to a previous magnitude of a previous perpendicular component, wherein an increase in magnitude of the perpendicular component is indicative of an increase in a heeling force on the subject.

9. A method comprising:

receiving first motion data from a first monitor device coupled to a first rigging member and second motion data from a second monitor device coupled to a second rigging member;

computing a first force that corresponds to the first motion data and a second force that corresponds to the second motion data;

computing a 3D vector based on the first force and the second force;

decomposing the 3D vector into at least a first direction-based component vector value;

comparing a magnitude of the first direction-based component vector value with a magnitude of a previous vector value to identify a change in force on a subject; and

updating a graphical user interface of a display device based on the change in force on the subject.

10. The method of claim 9, wherein the first force corresponds to a first tension in the first rigging member, and wherein the second force corresponds to a second tension in the second rigging member.

11. The method of claim 9, wherein the 3D vector is computed based on geometry or a material of the subject, the first rigging member, or the second rigging member.

12. The method of claim 9, wherein decomposing the 3D vector into at least the first direction-based component vector value comprises decomposing the 3D vector into three components.

13. The method of claim 9, wherein comparing the magnitude of the first vector value with the previous vector value to identify the change in force on the subject comprises comparing a current magnitude of a current parallel component to a previous magnitude of a previous parallel component, wherein an increase in magnitude of the parallel component is indicative of an increase in a driving force on the subject.

14. The method of claim 9, wherein comparing the magnitude of the first vector value with the previous vector value to identify the change in force on the subject comprises comparing a current magnitude of a current perpendicular component to a previous magnitude of a previous perpendicular component, wherein an increase in magnitude of the perpendicular component is indicative of an increase in a heeling force on the subject.
