PORTABLE CHARACTER INPUT APPARATUS AND METHOD USING CHANGE IN TENSION OF STRINGS CONNECTED TO FINGERS
First Claim
1. A portable character input apparatus comprising:
- 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.

Abstract
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.

8. A method of determining position of an input key on a keyboard by analyzing a change of tension on a first connection string attached to a wearing unit worn on a finger of a user according to movement of the finger, the method comprising:
-
receiving an digital tension value converted from tension change information about the change of tension on the first connection string from a sensor unit connected to the first connection string; in response to receiving the tension change information converted into the digital tension value, determining a keyboard row related to the received tension change information by comparing a value of the received electrical signal and threshold values for keyboard rows of the keyboard which are stored in a tension measurement information storage unit; and in response to determining the keyboard row, acquiring position information of an input key belonging to the determined keyboard row and related to the tension change information converted into the digital tension value with reference to a tension change information table with respect to changes of tension on the first connection string according to movements of the fingers excluding the thumb. - View Dependent Claims (9, 10)

- 11. The method of clam 8, wherein the determining of the keyboard row comprises checking whether the value of the received digital tension value is greater than or equal to the largest threshold value among the stored threshold values, and if the value is greater than or equal to the largest threshold value, determining a keyboard row including numbers/symbols.
