TouchPad Drawing Board
Our electronic drawing board integrates an easy human interface with a standard electronic display; specifically the a touchpad and an oscilloscope or TV screen.
The rationale behind the drawing board is to be able to create a free hand sketch using the touchpad and have a real time display on a screen which can later be sent to the computer once finalized.This idea came about after making countless reports that required drawings that take hours to perfect on a computer when in fact with a pencil it would only be a matter of minutes. In the market, tablets are gaining popularity but they are so expensive! Hence, we thought it’d be nice if we could simulate something similar under our $25 budget constraint.Thus we settled for using a touchpad to draw to an oscilloscope (and which EE doesn’t have an oscilloscope handy at home!). Better yet drawing to the TV!
