Description
Relabel supplied axis components under explicit orientation signs without inferring eye laterality.
Vision research uses stimulus angles, chart notations, image scales, viewing distances, coordinate origins, and observation windows. These quantities have different denominators and measurement conventions. A conversion or support share does not independently establish a visual measurement or its clinical interpretation.
Relabel supplied axis components under explicit orientation signs without inferring eye laterality.
When to use this tool
Use Ocular Axis Orientation Sign when you need this image, stimulus, notation, coordinate, or observation component for supplied research data.
How to use the tool and how it works
- Enter horizontal, vertical, horizontalPositiveTemporal, verticalPositiveSuperior. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read temporal, superior. Use the output convention below.
Independently reverse horizontal or vertical signs unless their positiveTemporal and positiveSuperior conventions are enabled. Return temporal and superior components.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| horizontal | Horizontal | Required. Finite number. |
| vertical | Vertical | Required. Finite number. |
| horizontalPositiveTemporal | Horizontal Positive Temporal | Required. Boolean. |
| verticalPositiveSuperior | Vertical Positive Superior | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| temporal | Temporal | Required. Finite number. |
| superior | Superior | Required. Finite number. |

}Limitations and assumptions
- Values retain their input unit. This is a supplied axis-sign mapping rather than a complete eye-specific coordinate transform, anatomical orientation determination, or clinical interpretation.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use calibrated acquisition and a documented visual or imaging protocol for complete interpretation. Confirm the reporting notation, viewing geometry, image scale, and support of the underlying observations.
