The PiPad is a Raspberry Pi tablet that uses our cross-platform Python app to replace traditional notebooks. Our goal is to produce an alternative to paper that is greener, more convenient and affordable for all.
We want to make the world a greener place. With deforestation an issue, it’s more important than ever to reduce our paper usage. That’s why our PiPad concept works as a ‘paperless notepad’. It is cheaper than most laptops, making it far more accessible, which means it can have a bigger impact on the world.
PiPad’s benefits don’t stop at its cost. Studies suggest that you’re more likely to remember information when taking written notes compared to when typing them. As you write on PiPad with a stylus, it would bring the same benefits to memory as paper.
We designed and printed a case to house the hardware, but the real challenge was in the software. We had to conceptualise an intuitive user interface and file system, create the canvas for user input and then use PyQt5 to implement the interface. We also had to code a machine learning algorithm to interpret text, using PyTesseract. Finally, we used CSS styling to improve the user experience.
If we could develop our prototype with more time and resources, we would add the ability to save images like sketches and diagrams, and improve our letter recognition algorithm.
