3-D Drawing Digital Pen

The world is turning into digital. However, humans cannot interact digitally all the time. Unfortunately, innovations for converting 3-D real-world objects into digital are limited to television-cameras only. So, some technologies like digital pens are required to deal with the 3-D real-world peculiarities. Even the most recent digital pens also operates in 2-D. "Wireless 3-D Drawing Digital Pen" is the required solution for the transform between the two domains. The proposed device can create a 3-D image on computer screen by drawing the object in the air virtually. This device can also recognize handwritten digit and gesture trajectory in 2-D. It is microcontroller based system with various user interfaces, memory and wireless communication which enables it to support real time operation.
