摘要： An apparatus and method for controlling a mobile communication terminal based on contact that allows input of various user's contact information through a contact sensor are provided, which includes a contact sensor contact sensor that includes a plurality of contact switches arranged in a grid array and sensing the user's contact to produce contact signals. A contact information generator generates contact information using the contact signals. A controller determines whether the contact information is preset contact information, and executes a command that is set corresponding to the contact information if the contact information is preset contact information, or sets a command to be executed corresponding to the contact information if the contact information is not preset contact information. The grid arrangement of the contact switches allows input of contact information using various methods. Accordingly, a user can directly set or modify a method for inputting a command for controlling a function.

摘要： The present invention relates to a Hangeul input keypad and a method using the same. Basic consonants and basic vowels are assigned to the Hangeul input keypad, the number of the basic consonant-assigned keys is less than that of the basic vowel-assigned keys, the consonant keys and the vowel keys are disposed separately, and a shift key converting the basic consonants to extended consonants is disposed adjacent to the consonant keys to which the basic consonants convertible to the extended consonants are assigned. The Hangeul input keypad and method according to the present invention improves speed of Hangeul input, provides convenience in operation of consonant keys and a shift key, and ease of a user's learning of the Hangeul input method by optimizing the disposition of the consonants and vowels.
