Comparison of Different Task Analysis Methods Based on Jack

With the rapid development of digital technology and artificial intelligence, human-computer interaction technology is becoming more and more important. Therefore, it is indispensable to establish a virtual human model to simulate the actual state. This paper firstly introduces the development status of virtual simulation and the reasons for establishing virtual human body models, and takes virtual human body weight-lifting cubes with different weights as an example to create virtual human body models, import objects, and perform statics simulation. Then, through the three analysis methods in the jack platform, perform task analysis on virtual human weight-lifting cubes with different weights, and output the comparison results. Finally, three analysis methods are compared and explained. Finally, the creation and perfection of virtual human are prospected.
