Movement analysis software that visualizes the joint moment in a computer graphic

ARMO Skelton Viewer-Analysis (formerly Moment Visual) is movement analysis software that simulates how much power is generated in a joint from the movement of the human body. Previously, the body's movement was illustrated only through numeric figures and graphs; with our software, such movement is visualized in 3D computer graphic animation in order to understand the joint moment against the movement. The system may be utilized for analysis of movement in research and education.

There is a video sample of the movement image on our Japanese site.

Three display modes exchangeable with Start/Stop button.
The button on the display from top to bottom

Walk (normal)
Walk (fixed view point)
Walk (trajectory of gravity center)



Function

Animation display

armo

The result of motion analysis is displayed through the use of a stick figure and skeletal model.
* The movement of the backbone, pronation/supination of forearm and shoulder blades will not be displayed in the 3D graphic of skeletal model

Graph display

armo

The joint angle, joint position, ground reaction force, joint moment and joint power necessary in biomechanics are displayed in graphs with simple drag and drop.

The movement of the test subject (rehab patient etc) is displayed in 3D animation using the musculoskeletal system model. Simultaneously calculated muscle moment, estimated muscle strength and calorie consumption are visualized using color changes in the muscle, directly displaying how much strength of the muscle is exerted in what point of the time of the movement.

Limitation

The system is composed of algorithm(s) based on a published paper on normal walking; verifications for other movements have not been sufficiently performed. 3D coordinate data (Coordinating 3D data) obtained in motion capture will be necessary for use of ARMO Skeleton Viewer Analysis. Furthermore, a force place is required for lower limb joint moment and muscle strength calculation. Please be reminded these measuring systems need to be arranged separately.


Availability of two versions

ARMO Skeleton Viewer
The result of joint moment calculated with "DIFFGAIT", the library software of the Clinical Gait Analysis Forum of Japan is visually displayed.


ARMO Skeleton Analysis
The joint moment is calculated with ARMO model (DIFF marker set) and the result is visually displayed. The calculation of joint moment and display are packaged in a set.

*Note - ARMO Skeleton View Analysis does not support muscle display.
