The project was shelved for a few months, due to not knowing how to continue and improve on the design in a way that could be accomplished at the time, mostly due to budget constraints and not having access to a 3D printer over the summer.
During this time, several methods of an easy to implement an input method were brainstormed:
- Button - would be too difficult to waterproof without a custom cap
- Encoder - (like apple watch) cool idea but hard to fit into a watch with standard components
- Accelerometer - (tap detection + gestures) easy to waterproof and implement into the watch
After seeing a few other watches with an accelerometer as input I got the idea to use one, as it solves all the problems of being difficult to mechanically implement while being robust and water proof.
