This project explores a physical input solution for touchscreen-based mobile gaming. I designed and built a modular mechanical controller to improve the touchscreen controls and gaming experience in mobile games, enhancing playability for mobile games that rely heavily on rapid touchscreen inputs. This controller offers customizable trigger buttons with tactile feedback and customizable inputs that simulate a human finger tapping on a touchscreen. The controller is made using DIY materials such as popsicle sticks and cardboard.
The controller is compatible with a wide range of smartphones with its adjustable handles that simply clip and attach to the sides of the phone, while still exposing the headphone port and charging port. Each trigger unit is also just as modular, as they're fully adjustable, detachable, and different units can adapt to suit different game UIs. Users can have the flexibility to change the number of triggers, their position and how they're mounted based on their device and the games they play. The result is one of the most practical projects I've done in a while, as I end up using this controller for many of my play sessions. This project was very rewarding as it combined my interests in gaming, mechanical design and hands-on prototyping to create a gadget that I ended up daily driving.
