Description
Require nonnegative contactSeconds and swingSeconds with positive sum and doubleContactSeconds within contactSeconds.
Foot and footwear research uses geometric dimensions, contact cells, forces, and measurement records. A length margin, normalized difference, or contact share has a specific measurement basis and can omit important three-dimensional or sensor effects. Arithmetic on supplied observations is separate from a validated clinical assessment.
Require nonnegative contactSeconds and swingSeconds with positive sum and doubleContactSeconds within contactSeconds.
When to use this tool
Use Foot Task Contact Time Swing Share when you have supplied foot, footwear, bench, or recording data and need this measurement or record-support calculation.
How to use the tool and how it works
- Enter contactSeconds, swingSeconds, doubleContactSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read cycleSeconds, dutyFraction, exclusiveContactSeconds. Use the output convention below.
Require nonnegative contactSeconds and swingSeconds with positive sum and doubleContactSeconds within contactSeconds. Return cycleSeconds=contact+swing, dutyFraction=contact/cycle, and exclusiveContactSeconds=contact-doubleContact.1

}Limitations and assumptions
- Durations are seconds under the caller's event definitions. No event detection, complete bilateral gait-cycle validation, or clinical interpretation is performed.
- 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. Signed zero is exported as zero.
Alternative or Complementary methods
Use a documented measurement protocol with calibrated equipment and appropriate geometric or contact models. Broader interpretation requires assessment of the underlying observations beyond one length, ratio, or support flag.
