Inspiration
Several Wii remotes, a UDraw tablet, and a dream to make hackathon attendees touch grass... virtually, of course.
What it does
- You can plant grass and flowers, water them to help them grow (or cut them down), and Touch! Some! Grass!
- We used Grafana to track statistics: how much grass you've touched, how long since you last touched grass, and what/how many plants you have planted (etc).
How we built it
We wrote a userspace driver in Rust tapping into the Linux kernel Wii Remote driver, to access the raw data sent by the drawing tablet through the Wii Remote and convert it into a standard graphics tablet.
We then wrote a game using the Monogame library for C# .NET to allow you to touch grass. The game also sends data to an InfluxDB server, which is then accessed by Grafana to create a dashboard with statistics from the game.
Challenges we ran into
Confusing documentation.
Accomplishments that we're proud of
Making a piece of old proprietary hardware useful, as a cheap wireless graphics tablet!
What we learned
The Linux input stack is weird.
What's next for Touch Grass Simulator (With Wii Controls)
Bushes & maybe trees.
