aframe-thumb-controls-component
An A-Frame component that provides and normalizes directional events for thumbpads and thumbsticks.
At the moment, A-Frame out of the box does not provide thumb-related
directional events, merely axismove/trackpaddown/trackpadup. We would
like events such as thumbleftstart and thumbleftend.
But also to solve the issue that the interaction between thumbpads (e.g., Vive) and thumbsticks (Oculus) are different. Thumbpads operate on clicks. Thumbsticks operate via pulls. This component normalizes the two to start and end events:
- A start event for thumbpads is to press down.
- An end event for thumbpads is to release after a press down.
- A start event for thumbsticks is to pull the stick far enough in a direction.
- An end event for thumbsticks is to release the stick such that it snaps back to center.
The component provides start and end events in each direction (as well as plain
thumbstart and thumbend event indicating any direction).
thumb-controls API
| Property | Description | Default Value | | -------- | ----------- | ------------- | | thresholdAngle | Degrees indicating size of target for up, left, right, down directions. Like a pie. | 70 | | thresholdPad | Minimum distance (from 0 to 1) that thumb needs to be from center to trigger event for thumbpads (e.g., Vive). | 0.05 | | thresholdStick | Minimum distance (from 0 to 1) that thumb needs to be from center to trigger event for thumbsticks (e.g., Oculus). | 0.75 |

| Event Name | |-----------------| | thumbstart | | thumbend | | thumbleftstart | | thumbleftend | | thumbrightstart | | thumbrightend | | thumbupstart | | thumbupend | | thumbdownstart | | thumbdownend |
thumb-controls-debug
There is a helper component that provides a thumb emulator that can be used on a 2D computer:
<a-entity oculus-touch-controls="hand: left" thumb-controls="hand: left" thumb-controls-debug="enabled: true; controllerType: oculus">
