A method for determining symbols input by a user on an input device having at least one key to which a plurality of symbols have been allocated comprises the steps of: tracking a plurality of input objects; receiving key input from any one of the plurality of input objects; and determining the symbol input by the user, based on the relative position of the input object which generated the key input - the position occupied in the plurality of input objects - and the input key. Consequently, different symbols can be output by using a single key depending on the relative position of the input object which generated the key input, and the desired symbols can easily be input using a small-sized input device. |
