Portable terminal for inputting three signals via one input key, and text input method using same
First Claim
1. A portable terminal capable of inputting three signals by one input key comprising:
- at least one input key, anda plurality of sensors sensing electrical signals positioned below the input key;
wherein a position of the input key pressed for the first time is set as the first reference point, and two second reference points are set on a left and right side at the same distance from the first reference point when the input key is pressed; and
an area A is between the two second reference points, a left side of the area A is set as an area B, and the right side of the area A is set as an area C, wherein a left one of the two second reference points is on a boundary between the area A and the area B and a right one of the two second reference points is on a boundary between the area A and the area C, and the size of area B and area C is variable depending on the position of the first reference point,one of three different letters, numbers or symbols is allocated to the A area, another of the three different letters, numbers or symbols is allocated to the B area, and the remaining one of the three different letters, numbers, or symbols is allocated to the C area,when the pressing is removed from the A area, the letter, number or symbol allocated to the A area is input,when the pressing is moved to the B area and the pressing is removed from the B area, the letter, number or symbol allocated to the B area is input, andwhen the pressing is moved to the C area and the pressing is removed from the C area, the letter, number or symbol allocated to the C area is input.

Abstract
According to the present invention a portable input terminal may be described. The input terminal may permit inputting letters in a portable terminal, letters that may be inputted more quickly than in conventional inventions because the present invention is set in a way that three different letters, numbers or symbols can be inputted by pressing one input key one time. Three letters, numbers or symbols may be inputted through one key and a plurality of sensors may be arranged effectively. The inputting accuracy significantly improves over the prior art, avoiding inputting errors by applying and developing various kinds of inputting ways using all characteristics of the present invention.

3. A method for inputting three different letters, numbers or symbols using one input key of a portable terminal comprising:
-
setting a first reference point and two second reference points, the first reference point is the place where the input key is pressed first, the two second reference points are on a left and a right side at the same distance from the first reference point when the input key is pressed; partitioning area into area A which is between the two second reference points, an area B which is on a left side of the area A and an area C which is on a right side of the area A wherein a left one of the two second reference points is on a boundary between the area A and the area B and a right one of the two second reference points is on a boundary between the area A and the area C, and the size of area B and area C is variable depending on the position of the first reference point; and inputting one of the three different letters, numbers or symbols, the inputting inputs one of the three different letters, numbers or symbols allocated to the A area when the pressing is removed from the A area, inputs another of the three different letters, numbers or symbols allocated to the B area when the pressing is moved to the B area and the pressing is removed from the B area, and inputs the remaining one letter, number or symbol allocated to the C area when the pressing is moved to the C area and the pressing is removed from the C area.
