INPUT DEVICE AND INPUT METHOD
First Claim
1. A method of determining a symbol input by a user in an input device including at least one key to which a plurality of symbols are allocated, the method comprising:
- tracking a plurality of input objects;
receiving a key input from any one of the plurality of input objects; and
determining the symbol input by the user on the basis of a relative position, which is an order of the input object among the plurality of input objects in a specific direction of the input device, of the input object that has generated the key input and the input key.

Abstract
Provided are an input device including at least one key to which a plurality of symbols are allocated, and a method of determining a symbol input by a user in the input device. The method includes tracking a plurality of input objects, receiving a key input from any one of the plurality of input objects, and determining a symbol input by a user on the basis of a relative position, which is a position of the input object in the input objects, of the input object that has generated the key input and the input key. Accordingly, it is possible to output different symbols using one key according to relative positions of an input object that has generated a key input, so that a desired symbol can be easily input through a small input device.

13. A method of determining a symbol input by a user in an input device, the method comprising:
-
setting M (M is equal to or less than N and greater than
1) valid input objects among N input objects according to an input of the user, allocating M symbols to at least one key, and providing an input means including the at least one key to which the M symbols are allocated;receiving, at the input means, a key input from any one of the valid input objects; and determining the symbol input by the user on the basis of a relative position, which is an order of the valid input object among the plurality of valid input objects in a specific direction of the input device, of the valid input object that has generated the key input and the input key. - View Dependent Claims (14, 15)
