  • Patent number: 11046247
    Abstract: A system and method for determining a probability that a driver will detect a hazard while driving. An eye tracker tracks the driver's forward and non-forward glance durations. A probability calculator categorizes the glance durations into an observation type and selects a transition matrix specific to that observation type. The probability calculator groups the glance durations and observation type into a tuple and calculates a probability that the driver will detect a hazard in the current time segment based on the tuple, the previous time segment's detection state, and the transition matrix. Based on whether the determined probability is above or below a threshold, the current time segment detection state is stored in memory as a detect state (driver is likely to detect a hazard) or a non-detect state (driver is not likely to detect a hazard). The driver is alerted if determined to be in a non-detect state.
