Setting up java
Do’s and Dont’s
Tools | R | Rest
Needs java 1.8 or higher
Creates a random server on your system
Features: streaming, r-lang, stats, remote control
Let’s check if you already have it!!
Open a terminal
MacOS - Finder > Applications > System > Terminal
Win - Start > execute > cmd
Try java JRE
Is it a no?
Just google "java jre 1.8". Choose the website from Oracle or OpenJDK. Don’t go for anything else.
If we have java, there is no additional problem. Just download it from Lince plus repo
Size aprox 200MB
Install like a normal program on Windows
If system asks for additional administrator rights, don’t worry
On MacOS is even easier, just decompress and execute file. Save the file in a save place
As we have seen Lince contains a lot of new features. Let’s discover the following concepts: start, project, player, stats, observers, results, scenes, traceability
When starts it creates a random server than changes every time of port. So, it will never be traced and the info is allways secured. The lince version is very important in this project.
Here we can see what Lince does. When it starts it will check a random available port.
If you have created a project before it loads it automatically
You can check the html address you can type on the browser
Check if the project info box appears
Create a new project, save it directly. Close and try if it works.
Open it, and close Lince again. It will allways ask you if you want to save changes.
If you see that file is just a simple XML file, easy to edit and to detect changes visually.
As a text file, you can upload it anywhere and do your change control system.
It is not really recommended modify it directly.
Let’s open the browser
Do you have a MacOS? Sorry!!!!
You will need to learn some network basics on the second part of the workshop. By now, try opening safari and type on the browser directly https://localhost:<port>;
This part is very simple!! What you can try is just click on '+' randomly and click directly 'save'. This feature will create all the codes automatically for your tool. After that change any thing you don’t like and that’s all!!
Important: Changing elements from your observation tool on the future, for example, deleting criteria that you have chosen on your visualizations, can create conflicts on your project!
Let’s go to the desktop app. Select any videos you want, on the option shown in the image.
Video order will be used on the player. Piece of advice: They must be synchronized or have the same duration!
After choosing videos and setting up our tool, let’s detect the scenes.
One person could manage scenes and the other analyze it.
This page has been design like the previous Lince, adding simultaneous video control and a more reactive user experience.
This page contains a very easy and fast way for data appearance.
You don’t need to install R Studio to play with Lince data
If you want to use r-studio for charting or more complex calculations with additional packages, you will need to attack Lince Plus from R Studio. It can be done via Rest services
Lince includes on its core a whole set of tools for transcoding data into csv, xls, json, yaml, xml and many many file types.
Will include many features more. Ask for them!
It has been created a whole tool set for allowing data integration between the old version, and all the additional market tools.
Don’t analyze a whole project and start changing your instrument afterwards. That can make your project very unstable and you will lose registered data.
Don’t use videos that do not have the same length. Lince can’t know which video you refer, and will use allways the first one of them to refer recording time.
Try all features before your starting your research
Check website for updates. A new installer will ease the task
Use several points of view with the new multivideo feature
Use the R module from inside and outside Lince
If you have a complex visualization tool, play better from big screens.
