What are the new features (or features) of Ubuntu 12.04 )? This version makes computers seem "spiritual ". Why?

Go to Ubuntu 12.04, no matter where you are, just click the key "Alt" and a helper HUD will appear in the upper left corner of the screen as follows: (Note: press the "Alt" key again, it will disappear immediately .)

It can be seen that the "icon" of the HUD is like a helmet of an airline pilot, indicating the origin of the HUD. The HUD is "Head-Up Display", which means "Head-Up Display", that is, as long as the airline driver looks at the front and focuses on the target, it does not have to look down at the dashboard data, the meter reading is projected on the window glass and is translucent for driver's reference. As a result, there is a "head-up display" (HUD) statement. Introducing HUD into the computer field is also a "whimsy", right?

What is the use of a translucent HUD panel? As long as you type the "intent" in your mind into the "HUD panel" in text (no matter which type of text), you guys, A "recommended List" (List) will appear immediately below the Panel, and the first option instantly increases the brightness to attract your attention, as long as you think the content of this option is more in line with your "intent", immediately press the "Enter key" and the computer will "receive the message". "The HUD tries to predict (prediction) which function or file the user wants as they type it in", The basic idea is: "It's driven by the idea that search or expressing your intent (intent) has become really powerful."

Obviously, HUD uses artificial intelligence (Fuzzy Matching, Fuzzy Matching, and machine learning ). However, is the HUD helper very intelligent at this time? Can it guess your "intention"? In fact, HUD is not intelligent at first, but it will keep learning automatically and explore your habits and intentions, which will become more intelligent.

For example, because of your carelessness, you have reversed the order of letters, for example, converting "Firefox" into "Firefxo ". This doesn't matter. HUD will immediately notice that you know that your real intention is "Firefox", and it will suggest you use "Firefox ". It is not easy to do this. The theory behind the HUD is based on the so-called "edit" distance proposed by Russian scholar Levenshtein in 1965, that is, how to define the "edit" distance between two strings. It is not hard to imagine how much computing workload is required to find a "Most like it" string among the other 100 strings. I don't know how Ubuntu developers solve this problem. The HUD technology is not a simple "copy" for searching, searching, and matching ".
