The objective of the study is to evaluate an innovative child safety seat user engagement system (CCS system) designed to actively educate, instruct, and alarm caregivers with information associated with automatically-sensed safety seat misuses/errors via a smartphone application.
The primary objective of the study is to evaluate whether child safety seat users correct more critical misuse errors in child safety seat usage with the seat with the CCS system than the same seat with no sensor system. The CCS system will provide ongoing, tailored support to users at the time of an error. Videos will be available to users via a smartphone and provide short "how to" instructions that demonstrate how to correctly perform each safety seat behavior (e.g., tighten harness straps) and how to avoid common mistakes. The overall goal of the CCS system is to prevent child safety seat critical misuses and reduce deaths and injuries in children riding in motor vehicles. In the proposed study, adult participants will be asked to attend one in-person study visit and complete three (3) scenarios in which they will be asked to identify and correct errors in child safety seat use. Participants will be randomized to either the intervention group which will use the CCS system during each scenario or the control group which will not use the CCS system during each scenario.

Number of Participants With Installation Errors
For each misuse scenario participants will be asked to correct the error in the seat installation or the harness tension. Convertible seats will be used for this phase. For each scenario, we will use a huggable images test doll (age and weight of the doll will be indicated to participants). Study team will record seat direction (forward vs rear facing), harness tension (newtons), insecure attachment of the seat to the vehicle (yes/no).
Time frame: Once during the only study visit: up to 30 mins
