Interaction is one of the most important characteristic of VR system. In this paper, a kind of Hierarchical Timed Color Petri Net (HTCPN) is defined and an Interactive Manager Model (IMM) of Virtual Maintenance Environment (VME) is established based on HTCPN. With the inputs including operation data from dataglove, collision information between objects and recognized assembly relationship, the IMM output concrete operation event to realize the interactive actions in VME such as navigation, dragging, assembling and disassembling. The practice test illustrate that IMM satisfied the requirements of VME such as real-time and incurrent, as well as realized the treatment of numerous discrete events and the capture of operation intend during virtual maintenance operation.

Aiming at the human–computer interaction control (HCIC) requirements of multi operators in collaborative virtual maintenance (CVM), real-time motion capture and simulation drive of multi operators with optical human motion capture system (HMCS) is proposed. The detailed realization process of real-time motion capture and data drive for virtual operators in CVM environment is presented to actualize the natural and online interactive operations. In order to ensure the cooperative and orderly interactions of virtual operators with the input operations of actual operators, collaborative HCIC model is established according to specific planning, allocating and decision-making of different maintenance tasks as well as the human–computer interaction features and collaborative maintenance operation features among multi maintenance trainees in CVM process. Finally, results of the experimental implementation validate the effectiveness and practicability of proposed methods, models, strategies and mechanisms.

As a new teaching mode, online courses have become one of the most important teaching methods in higher education. At present, there are still some shortcomings in online course live broadcast teaching platform including insufficient hardware support, low flexibility and weak interactivity. Meanwhile, during the entire online course teaching process, teachers do not know the overall learning effect of students in real time to determine the next teaching plan. This study presented a real-time interactive technology to enhance the interactive of the entire online course broadcast teaching platform. At the same time, it combined a monitoring method for online course terminals, servers and learning process to demonstrate students’ learning effect in the whole online course learning process, and finally built the online course broadcast teaching platform. The practice test in teaching shows that the online course broadcast teaching platform can improve the teaching effect among students, which is of great significance for the improvement of teaching quality.
