Man kills his girlfriend because of emotional disputesYesterday morning, the 30-year-old defendant Zhang was taken to the Grand Court of Beijing No. 1 Intermediate People's Court by the bailiff. On the prosecution side of the court, there are two rows of seats. The first row is the relatives and agents of the three prosecutors and the victims, and the second row is the technical staff who operates the “visual demonstration systemâ€.
The prosecution alleged that on September 13, last year, the defendant Zhang was in a company office in Haidian District.

Witness control handle restores the scene
In the evidence-proven section, the only witness in the case, Dong Mou, appeared in court to testify. He is a victim's colleague. "Dong, please look at the big screen of the court. This is the scenario of our simulated office. One male and one female are simulating the defendant Zhang and the victim Liu." Public prosecutor Zhao Peng asked the witness Dong to wear VR glasses and use Hand-operated handles control the direction and position. "Please use your perspective to restore the situation at the time of the incident. Slower operation, do not shake, you can talk while operating."
After Dong put on VR glasses, the office scene on the big screen began to turn. "At the time I stood behind the victim Liu, Zhang asked Liu for something, and soon Zhang started to use the knife to tie himself." The operation of a large screen is constantly changing.
After Dong’s demonstration, the prosecutor showed the testimony of another witness through the court’s large screen. Different from the previous slide show at the testimony, the prosecutor recited the key on the touch screen in front of him and the red line appeared below the transcript on the corresponding big screen.

PPT software is still the most commonly used aid for prosecution courts to demonstrate. However, when using the PPT software, the evidence photos must be inserted one by one, which is time consuming and laborious. The clarity of the inserted photos is degraded and there is no guarantee of HD display in the courtroom. There is also the PPT software can not be adjusted and annotated according to the evidence photo. To this end, the city inspection branch, developed a "visual demonstration system for appearance." It is understood that the system will be promoted to the city's procuratorial organs.
The visualization system reflects four effectsWhy use the visualization system as a specialized aid for the prosecution’s court testimony? The city inspection and inspection said that this is to show the original appearance of various evidence materials in a more convenient and intuitive way by means of advanced information technology.
The first is to improve work efficiency: to achieve the synchronization of review and court preparation. The prosecutor can import the electronic file into the system in just one minute, and then the system can be used to review the case. During the review process, the prosecutor can use the “marking†function in the system to scribe, enlarge and annotate the photo of the file, and then “join the demonstration plan†directly, and use it directly at the court. There is no need to make a multimedia presentation before the court. certificate.
The second is to focus on court effectiveness: free and flexible demonstration according to the needs of the trial. After the HD electronic file photo was imported into the system, there was no change in resolution, size, and specifications. The public prosecutor can use the touch screen computer to zoom in and out on the evidence on the spot according to actual needs. The advantages of the HD electronic file photo are fully displayed in the process. The details of the evidence can be clearly displayed in the court without the enlarged form of the screenshot. .
The third is to stand up in court: the process of achieving evidence in court selection is transparent. The demonstration system for appearing in court includes a unique "real-time projection screen" (or "flying screen") technology. The public prosecutor can first query, select, occlude or sequentially adjust the evidence in the demonstration computer, and then pass the "real-time projection screen". The function projects evidence to the terminal display. In addition, the prosecutor can also use the functions of “brushâ€, “whiteboardâ€, “highlighting†and “selected enlargement†to mark and prompt the evidence photos, making the evidence selection process transparent and enhancing the persuasiveness of the public prosecutor to prove the facts of the case. .
The fourth is to strengthen the effectiveness of evidence: to enhance the persuasiveness of the public prosecutor's court testimony. The demonstration system for appearing in court improves the universal player of the computer. The public prosecutor can not only control the starting and ending position of the playback more conveniently, but also directly perform the marking operation such as circle circle and selected magnification in any frame of video, which enhances the public prosecutor's evidence of audiovisual materials. Control.
Litecoin is an online currency based on peer-to-peer technology and is an open source software project under the MIT/X11 license. It can help users make instant payments to anyone in the world [2]. Litecoin was designed and programmed by a programmer (Li Qiwei) who used to work at Google, and launched on January 9, 2011. Litecoin is an improved digital currency inspired by Bitcoin. The technical principle of Litecoin is the same as that of Bitcoin. It also adopts a decentralized architecture, without any central authority control, and the issuance of new coins and the transfer of transactions and payments are based on open source encryption algorithms, etc. These are all imitated the design principle of Bitcoin. However, Litecoin tries its best to improve the shortcomings that Bitcoin has shown before, such as too slow transaction confirmation, small total cap, the emergence of large mining pools caused by proof-of-work mechanism and so on, SHA256 algorithm [1].
Litecoin, which aims to improve Bitcoin, has three significant differences. First, the Litecoin network can process a block every 2.5 minutes instead of 10, thus providing faster transaction confirmation. Second, the Litecoin network is expected to produce 84 million litecoins, four times the amount of money issued on the Bitcoin network. Each litecoin is divided into 100 million smaller units, defined by eight decimal places.
