finger tracking writer, software engineering

I am looking for a software/hardware engineer to develop blueprint designs and design instructions for a electronic device that has the following capabilities: To develop realistic, engineered blueprint design options for a electronic device that enables the user to write and record written notes in the air space infront of them. They would use their finger to write in the space infront of them in the air. The user would use a smart eye piece or smart eye wear to view the writing. The writing would be superimposed. The motion trail of the finger when activated would be the pen for the writing. The writing can be saved, sent and uploaded to the cloud in the same way any electronic written notes would. HARDWARE: 1. finger/glove/index finger 2. smart eye wear ( off the shelf model or new model) 3. controller/base (if needed) The designs must identify the technology and the steps to develop and design the device.
