The Tegic Communications corporation developed, letter input method of word estimate type. It is one of the methods of being devised in order to do letter input efficiently in the key which with the letter input system for the portable telephone, is limited.

Using T9, the case where it inputs letter, estimate word that it inputs only consonant, it is indicated as candidacy, it selects the word which from among those we would like to input. Usually, if for example it is kana letter, consonant is allotted every key, means to input intended letter by several degrees pushing the same key, but because with T9 1 letters the frequency which pushes the key the occasion where it inputs 1 times, it is possible to do input quickly.

T9 included Japanese, it corresponds to many languages. In Japanese edition among these you can store to the dictionary 65,000 languages, not only the portable telephone, being utilized as application for letter input is considered with the embedded type equipment of PDA and the like.

As for basic shape of tablet PC there are 2 types. The same throughput as the usual notebook PC was built in inside the liquid crystal panel, expandability to the peripheral device was had, “pure tablet type” (“slate tablet type”) with, in the notebook PC specification of tablet PC such as pen input and revolution possible display was included in length and breadth, “compatible type” is.

Windows XP Tablet PC Edition which the Microsoft corporation developed is used to OS. This for the general consumer of the same company with the derivative version of Windows XP which OS is for personal computer, is the extended edition which adds tablet PC individual performance.

Tab key
