Towards hand gesture based writing support system for blinds

作者：

Highlights：

• A new dactylology is proposed to achieve functionality similar to a standard keyboard.

• A new feature extraction technique called as reduced shape signature (RSS) is introduced.

• Use of difference angle and polygonal area is proposed to discriminate Intra-class gestures.

• Symbols are entered in the Microsoft Word application with the proposed experimental setup and real time data entry support is verified.
