A 2018 project demonstrates how to convert a MacBook into a touchscreen using just $1 worth of hardware, leveraging computer vision techniques. The approach is a creative DIY solution that repurposes existing hardware rather than requiring expensive modifications. It highlights accessibility and innovation in hardware hacking, though it remains a niche experiment rather than a mainstream solution.
Background
Touchscreen functionality is typically built into devices at manufacture, but hobbyists often explore ways to add such features retroactively. Computer vision and affordable sensors have enabled various DIY input methods over the years.
