创新背景

犯罪学课程中实践教学的调查并不容易，借助科技手段有助于模拟现实，获得一些实践经验。

创新过程

鲁汶大学生物医学犯罪学相关的课程运用虚拟现实技术创建一种新程序，帮助学生检查虚拟犯罪现场，获得有益的实践经验。

虚拟现实技术建立的新程序包括3D环境、VR头显和双手控制器，看起来很像电脑游戏。学生使用这种程序后会处于三种情况之一：双重谋杀和抢劫、双重激情犯罪以及可能是谋杀或自杀的可疑死亡。
当到达虚拟犯罪现场后，会有虚拟警察向学生通报情况，之后学生会进入房子搜索。虚拟环境和实体犯罪现场一样，学生可以打开橱柜和门，识别痕迹并进行测试；采集DNA样本，用化学发光喷雾或红外光使血液痕迹可见；使用蓝光搜索痕迹，可视化指纹和拍照。程序会对采集的样本进行实时监控和测试，让教师或学生轻松进行评估。

除了模拟犯罪现场，虚拟现实还在课程中模拟了法庭。VR系统会监测学生的举动，当学生不小心污染证据之后，系统会及时对其做出提醒。鲁汶大学的教师Bram Bekaert表示，用于调查犯罪现场的技术正变得越来越敏感，因此确保调查人员的DNA没有最终进入犯罪现场样本或DNA痕迹在证据之间交换变得更加重要。

教师在学生完成虚拟调查后制定并起草了一份报告，让学生在模拟法庭中进行辩护，为未来的律师提供了虚拟环境中的实习机会。此外，VR系统主导的新程序对警察也非常有用：在现实生活中，警察对犯罪现场的调查次数有限，但在虚拟环境中，警察可以快速确定改进点或熟悉调查犯罪现场的挑战。

创新关键点

将虚拟现实技术运用于犯罪学教学，帮助学生构建模拟实践环境，在虚拟的犯罪现场中获得实践经验。

Virtual reality helps enable criminology teaching practices

The biomedical criminology-related course at the University of Leuven uses virtual reality technology to create a new program that helps students examine virtual crime scenes and gain useful practical experience.

New programs built by virtual reality technology, including 3D environments, VR headsets, and two-hand controllers, look a lot like computer games. Students using this program regret being in one of three situations: double murder and robbery, double passion crimes, and suspected deaths that could be murder or suicide.

When they arrive at the virtual crime scene, a virtual police officer informs the student of the situation, after which the student enters the house to search. Virtual environments, like physical crime scenes, allow students to open cabinets and doors, identify traces and conduct tests; Taking DNA samples and making blood traces visible with chemiluminescent spray or infrared light; Use blue light to search for sperm traces, visualize fingerprints, and take photos. The program monitors and tests the collected samples in real time, making it easy for teachers or students to evaluate.

In addition to simulating crime scenes, virtual reality also simulated courtrooms in the course. The VR system monitors the student's behavior, and when the student accidentally contaminates the evidence, the system will promptly remind them. Bram Bekaert, a faculty member at the University of Leuven, said the technology used to investigate crime scenes is becoming increasingly sensitive, so it's becoming more important to ensure that investigators' DNA doesn't end up in crime scene samples or DNA traces are exchanged between pieces of evidence.

Faculty develop and draft a report after students complete a virtual survey that allows students to defend themselves in a moot court, providing future lawyers with internship opportunities in a virtual environment. In addition, the new program led by vr systems is also very useful for police: in real life, police have a limited number of investigations of crime scenes, but in a virtual environment, police can quickly identify improvement points or become familiar with the challenges of investigating crime scenes.
