LED and Screen Feedback

Interpret Deep Throat Trainer position feedback using color, text, and movement together.

The LED strip provides quick position feedback, but color must never be the only source of meaning. Use the screen text, target indicator, and your controlled movement together.

During a segment

Visual state	Meaning in current user guidance	Response
Green / in target	measured position is within the target window	maintain only while comfortable
Yellow / ahead	measured position is shallower or ahead of the target	use the screen direction; adjust gradually
Red / behind or outside	measured position is deeper, behind, or outside the target	use the screen direction; stop rather than force a correction

Firmware and mode can alter presentation. The accompanying text and position indicator are authoritative when a color appears inconsistent.

Non-training states

Idle, completion, grade, and failure screens may also use color. Always pair the color with the visible label such as complete, grade, failed, or an error code.

If color is difficult to distinguish

Use the on-screen position/target display.
Reduce environmental glare.
Choose a pace slow enough to read the display.
Do not ask another person to direct deeper or faster movement based on color alone.

Unexpected feedback

Symptom	Check
feedback does not change	sensor path, mount stability, toy assignment, and calibration
feedback seems reversed	screen direction and current mode; stop and recalibrate if uncertain
colors flicker at a boundary	slow down and widen or lower the template target if available
no LED but screen works	continue only if screen feedback is sufficient; report repeated hardware behavior
