OpenVibe

OpenVibe is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand OpenVibe rather than just read about it. In short: OpenViBE is a software platform dedicated to designing, testing and using brain-computer interfaces. The package includes a Designer tool to create and run custom applications, along with several pre-configured and demo programs which are ready for use.

Key takeaways

OpenVibe belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OpenVibe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OpenVibe from memory before moving on to harder problems.

Reference excerpt

OpenViBE is a software platform dedicated to designing, testing and using brain-computer interfaces. The package includes a Designer tool to create and run custom applications, along with several pre-configured and demo programs which are ready for use. OpenViBE is software for real-time neuroscience (that is, for real-time processing of brain signals). It can be used to acquire, filter, process, classify and visualize brain signals in real time.

Applications The main OpenViBE application fields are medical (assistance to disabled people, real-time biofeedback, neurofeedback, real-time diagnosis), multimedia (virtual reality, video games), robotics and all other application fields related to brain-computer interfaces and real-time neurosciences. OpenViBE users can either be programmers or people not familiar with programming. This includes medical doctors, video game developers, researchers in signal processing or robotics, etc. Since 2012, the start-up Mensia Technologies has developed an advanced version of the software called NeuroRT Suite.

Interface The user interface of OpenVibe is easy to use for creating BCI scenarios and saving them for later use, to access and to manipulate. OpenVibe is the first library of functions written in C++ of this type developed by INRIA - Institut national de recherche en informatique et automatique (France) - it can be integrated and applied quickly and easily .

Worked examples

Example 1 — a first encounter with OpenVibe

Start with the simplest possible case. Write down what OpenVibe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to OpenVibe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about OpenVibe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of OpenVibe

In research: OpenVibe appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses OpenVibe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: OpenVibe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brain–computer interface, Electroencephalography, Evoked potentials, so understanding it makes those chapters shorter.
In everyday life: Look for OpenVibe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is OpenVibe in simple terms?

Why does OpenVibe matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OpenVibe?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
