Input Action now maps keys to movement and events in Preview. Understand how to speed up testing without confusing simulation with real use.
Direct answer
Lens Studio 5.18 added keyboard support to the Input Action component and the Bitmoji Player package for testing in Preview. The documentation shows movements with W, A, S and D and actions with the space bar, useful when multiple taps are difficult to reproduce in the editor. The feature improves iteration and regression, but keyboard does not represent camera, gesture, body movement, latency or device ergonomics. Validation must combine deterministic simulated cases with phone, Camera Kit or Spectacles sessions.
Deterministic input speeds up regression
Sticky keys help you repeat paths and compare states after logic or scene changes.
Action uncouples device
Mapping high-level intent allows you to change keyboard, touch or control without rewriting the entire experience response.
Preview has physical limits
Lighting, framing, occlusion, movement and attention only fully appear in the context of use.
Precise criteria coverage
List trajectories, states, errors and expected results; a repeatable test without assertion just repeats moves.
Nexus Reading
Use the keyboard in the quick cycle, record scenarios and reserve gates on the device for tracking, comfort, accessibility and performance.
FAQ
Since which version does Input Action accept a keyboard?
Snap reports Lens Studio 5.18 or later.
What actions can be simulated?
Documentation shows movement, rotation, events, and responses such as moving objects or calling components.
Does Preview replace testing on Spectacles?
No. It speeds up logic, but hardware and real context are still needed.
