# Uncertainty Handling

LETSTOP’s system is engineered with precision and safety at its core, incorporating built-in safeguards to manage ambiguous user input during drives.\
When the system cannot definitively determine whether an event is a true screen interaction or incidental movement, it defaults to not registering the interaction. This conservative approach preserves the integrity of a user’s driving score and ensures only verified phone use impacts their rewards.

To further enhance accuracy, LETSTOP uses motion profiling to differentiate between general handling and purposeful screen touches. The algorithm is calibrated to ignore the first touch in any driving session, treating it as a possible potential error.\
Phone use is only registered from the second confirmed touch, significantly reducing the likelihood of penalizing accidental taps or passive movements.

This logic reflects a safety-first design philosophy: it ensures that users are rewarded for truly distraction-free driving while maintaining fairness in data interpretation.\
By capturing only meaningful interactions, LETSTOP encourages better habits, reduces anxiety about being penalized unfairly, and improves user trust in the scoring system.<br>
