Problems solved by technology

This kind of scene is generally fixed and one-way interactive. The user can touch the objects in the scene through the force feedback ball, but cannot add or modify the objects in the scene in real time.
Objects for force feedback interaction generally have parameters such as hardness, static and dynamic friction, and penetration. If they cannot be adjusted dynamically and in real time, it will bring great limitations to the simulated surgery.

Embodiment 1

[0038] The present invention uses the Unity engine combined with the OpenHaptics interface of the GeomagicTouch force feedback device, and through the form of local plug-ins, proposes to realize the two-way interaction of the simulated surgical scene, so that the user can dynamically add and delete the force feedback objects in the scene, modify the parameters of the force feedback objects, Modify the mapping space of somatosensory equipment to make the surgical simulation process more realistic and flexible.

[0039] Such as figure 1 Shown, in order to solve the above problem, the present invention comprises following three main modules (hereinafter referred to as module 1. 2. 3.): 1. C++ end class library file, the function interface that provides force feedback ball, calls for Unity end. At the same time, the synchronized somatosensory object information in the Unity scene is saved; ②The C# file on the Unity side calls the C++ class library in the form of a local plug-in, a...

Abstract

The embodiment of the invention provides a method and a system for controlling parameters of a force feedback device in real time by using a Unity engine. The interaction with a user is realized through a Unity 3D engine; through a real-time monitoring mode, user operation parameters are transmitted to the force feedback thread, real-time modification of force feedback device parameters is achieved instead of single parameter transmission of traditional force feedback control, then a user is not allowed to modify somatosensory object parameters, and the flexibility and the experience effect offorce feedback in medical teaching simulation are improved.

Description

technical field [0001] The invention relates to real-time control of force feedback mechanisms, in particular to a method and system for real-time control of force feedback device parameters using a Unity engine. Background technique [0002] Virtual medical simulation technology is a very important aspect in the current medical field. This technology is gradually becoming the link between medical students' theoretical knowledge and clinical operations. Due to factors such as cost and risk, medical students are often unable to truly experience the surgical process. Due to its high reusability, flexibility and simulation, virtual medical technology just fills this gap. In the operation process, the mechanical interaction experience is a crucial part, which determines the authenticity of the operation feel and is closely related to the training effect of medical students. [0003] The current medical simulation software all use the fixed scene mode, that is, through the imag...
