Ubuntu 12.04 's Artificial Little Helper HUD Introduction

What are the new features (or new faces) of the Ubuntu12.04 version? This version makes the computer seem to have "spirituality". Why.

Enter the 12.04 version, no matter where you are, just click on the key "Alt", in the upper left corner of the screen will appear a small helper HUD is as follows: (Note: Click the "alt" key again, it will disappear immediately.) ）

Visible from the above, HUD's "icon" is like an airline driver's helmet, indicating the origin of HUD. HUD is "Head-updisplay", meaning "up to show", that is, as long as the air pilot visual front, focus on the goal, do not have to look down the dashboard data, and meter readings projected on the window glass, translucent-like, for the driver to refer to. Thus there is the "head display" (HUD). The introduction of HUD into the field of computing is also considered a "fantastic thought".

What is the use of the translucent HUD "Panel" (panel). As long as you put the "intention" of the mind in words (regardless of which text) type "HUD Panel", you, immediately below the panel will appear a "suggestion List" (list), and the first option to increase the brightness of the instant to attract your attention, as long as you think this option is more consistent with their "intent", Press "Enter" immediately, and the computer will "lead the line". In English this means: "The HUD tries to predict (predictive) 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. "

Obviously, HUD uses artificial intelligence (fuzzy matching and machine learning). But is the HUD Small helper very smart at this time? It can be guessed by your "intentions." In fact, HUD is not smart enough, but it will continue to learn automatically, fumbling with your habits and intentions and becoming more and more intelligent.

For example, because of your carelessness, the order of the letters is reversed, such as "Firefox" as "Firefxo". It doesn't matter, HUD will immediately be aware that your real intention is "Firefox", it will suggest you use "Firefox browser." It is not easy to do this. The rationale behind HUD is based on what the Russian scholar Levenshtein in 1965 called the "edit" distance, that is, how to define the "edit" distance between two strings. It is not hard to imagine that given a string, it would require a "most like" string to be found in the middle of the other 100 strings, and how much work would be calculated. I don't know how the Ubuntu developer solves the problem. HUD technology is not a simple "copy" of finding, searching, and matching.
