Soon after the Nintendo Switch was released in March 2017, digital artists have been using the controllers, called Joycons, as a hand-held controller for digital painting. In contrast with all previous low-cost single-hand game controllers we tried before, the joycons ($80 a pair ) are equipped with gyroscopes, accelerometers and even IR motion camera.
The joycons works on Windows even without installing a driver but the analog thumb-stick only works as digital buttons. Thanks to this Joycon driver for Windows by Matthew Fosse, we can now also use the analog joystick (and maybe later the gyroscope too).
After installing vJoy and Joycon driver as instructed by the Joycon driver page, we are able to use Joycon for quick controls for Expresii. We had to connect the Left joycon instead of having left and right combined, since the mapping of the combined controls is different from what Expresii currently accepts. We tried x360ce to remap the controls but we didn't figure out how yet. :) Currently, Joycon driver outputs gyroscope data as rotational impulses rather than tilt angles so we can't really make use of the gyroscope for brush tilt yet. Anyway, here is a short video of using Joycon with Expresii:
We thank Mandy Ng of Rooftop Animation for providing the Joycons.
