1. A computing device, comprising: a logic subsystem; and a data storage subsystem comprising instructions stored thereon that are executable by the logic subsystem to: receive sensor data from a sensor system including one or more sensors configured to acquire the sensor data by monitoring a use environment; associate the sensor data with a user; recognize a current state of each of one or more use environment state features associated with the user via the sensor data; store the current state of each of the one or more use environment state features; detect a triggering condition for a selected use environment state feature; and upon detecting the triggering condition, provide information related to the selected use environment state feature based upon one or more of the current state of the use selected use environment state feature and a previously-stored state of the selected use environment state feature.
