A portable character input apparatus which is compact and uses strings connected to each finger to input characters. The portable character input apparatus includes a plurality of wearing units, each configured to be worn on or attached to a finger; at least one or more first connection strings, each configured to be attached to the wearing units; a detecting unit configured to detect a change of tension on the first connecting string according to movement of the finger wearing the wearing unit; and a tension change analysis unit configured to analyze the change of tension detected by the detection unit to determine position of an input key that corresponds to the movement of the finger. Accordingly, a keyboard row is determined based on a change of tension related to a user's finger movement, and then position of an input key belonging to the keyboard row can be obtained.
