Thought recording and reproduction device

Thought recording and reproduction device 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 Thought recording and reproduction device rather than just read about it. In short: A thought recording and reproduction device refers to any machine which is able to both directly record and reproduce, via a brain-computer interface, the thoughts, emotions, dreams or other neural/cognitive events of a subject for that or other subjects to experience. While currently residing within mostly fictional displays of the capacity of such devices, the idea has received increased scientific currency since…

Key takeaways

Thought recording and reproduction device 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 Thought recording and reproduction device to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Thought recording and reproduction device from memory before moving on to harder problems.

Reference excerpt

A thought recording and reproduction device refers to any machine which is able to both directly record and reproduce, via a brain-computer interface, the thoughts, emotions, dreams or other neural/cognitive events of a subject for that or other subjects to experience. While currently residing within mostly fictional displays of the capacity of such devices, the idea has received increased scientific currency since the development of the first BCI-enabled devices. The term oneirography, referring to the recording of dreams, is also a synonym for the above.

Fiction

This hypothetical technology is a key element in some of the early short stories of William Gibson, including his 1977 debut Fragments of a Hologram Rose, where it is called ASP (Apparent Sensory Perception). In his Sprawl trilogy, it is termed Simstim (Simulation Stimulation), and described as the most popular form of entertainment, perhaps equivalent to 20th century pop music. Whereas most instances depict a heavily edited documentary version, replaying an approximation of the actual experience of the person recorded, in The Winter Market a version able to record dreams and imaginations exists. A number of films from the 1980s onwards, such as Brainstorm (1983), Until the End of the World (1991), Strange Days (1995), Final Fantasy: The Spirits Within (2001), and Sleep Dealer (2008), depict the technology and its ramifications.

Research In December 2008, Advanced Telecommunications Research Institute International's Department of Cognitive Neuroscience announced its own research into the translation of neural signals into images. In addition, Prof. Moran Cerf of Caletch published a paper in Nature where he described work that allowed for the real-time interpretation of thoughts. The research outcome has often been popularized as a device that could record dreams. Prof. Moran Cerf discussed the specifics of the work and the theoretical possibilities in various public talks.

Current limitations BCI devices can currently translate a limited subset of neural signals into digital signals, most of which are utilized for motor-centric controls of attached devices. The translation of images perceived or conceived within the brain has not yet been fully achieved.

Worked examples

Example 1 — a first encounter with Thought recording and reproduction device

Start with the simplest possible case. Write down what Thought recording and reproduction device 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 Thought recording and reproduction device 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 Thought recording and reproduction device 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 Thought recording and reproduction device

In research: Thought recording and reproduction device 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 Thought recording and reproduction device 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: Thought recording and reproduction device is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brain–computer interface, Dreams, so understanding it makes those chapters shorter.
In everyday life: Look for Thought recording and reproduction device 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.
