Head-up display A head-up display HUD is a transparent display that presents data without requiring users to look away from their usual viewpoints. A precursor technology to augmented reality, heads-up displays were first developed for pilots in the s, projecting simple flight data into their line of sight, thereby enabling them to keep their "heads up" and not look down at the instruments.

This is the average daily time, so to recover the annual time spent, we simply multiply by Suppose we were interested in how much time a flashcard would cost us over 20 years. The average daily time changes every year the graph looks like an exponential decay, rememberso we have to run the formula for each year and sum them all; in Haskell: Spaced repetition can accommodate dozens of thousands of cards.

See the next section. To a lesser extent, one might wonder when one is in a hurry, should one learn something with spaced repetition and with massed?

How far away should the tests or deadlines be before abandoning spaced repetition? Quotidian uses, but all valuable to me. With a diversity of flashcards, I find my daily review interesting. Housman poetry, followed by a few quotes from LessWrong quote threadsand so on.

This takes under 20 minutes, which is not too bad. By Februarythe daily reviews are in the 40s or sometimes 50s for similar reasons, but the gradual shrinkage will continue. We can see this vividly, and we can even see a sort of analogue of the original forgetting curve, if we ask Mnemosyne 2.

But because it is using spaced repetition, keeping up is easy.

Other forms of memory are still more powerful. Marcus says the other instances of hyperthymesia resemble Price. When to review When should one review? The studies demonstrating the spacing effect do not control or vary the time of day, so in one sense, the answer is: So one reviews at whatever time is convenient.

Convenience makes one more likely to stick with it, and sticking with it overpowers any temporary improvement. Memory consolidation seems to be related, and sleep is known to powerfully influence what memories enter long-term memory, strengthening memories of material learned close to bedtime and increasing creativity ; interrupting sleep without affecting total sleep time or quality still damages memory formation in mice So reviewing before bedtime would be best.

Other mental exercises show improvement when trained before bedtime; for example, dual n-back. Neural growth may be related; from Stahl Recent advances in our understanding of the neurobiology underlying normal human memory formation have revealed that learning is not an event, but rather a process that unfolds over time.

Furthermore, 2 weeks after testing, animals trained in discrete spaced intervals over a period of time, rather than in a single presentation or a massed trial of the same information, remember better.

One theory is that the hippocampal neurons that preferentially survive are the ones that are somehow activated during the learning process.

What are all our flashcards, small and large, doing for us?

Why do I have a pair of flashcards for the word anent among many others? I can just look it up. But look ups take time compared to already knowing something. We trade off lookup time against limited skull space.

Consider the sort of factual data already given as examples - we might one day need to know the average annual rainfall in Honolulu or Austin, but it would require too much space to memorize such data for all capitals. There are millions of English words, but in practice any more thanis excessive.

More surprising is a sort of procedural knowledge. An extreme form of space-time tradeoffs in computers is when a computation is replaced by pre-calculated constants. We could take a math function and calculate its output for each possible input. Usually such a lookup table of input to output is really large.Published: Mon, 5 Dec Smartphones are sophisticated devices used for communication while offering many other different functions at the same time.

These functions may include video and audio recording, navigation assistance, music and video player and web browsing through wireless networks and apps ranging from games to highly specialized dictionaries.
