研究概览
简要总结
This study aims to assess the usability of a load leg design for caregivers who must install the child safety seat into a vehicle. The specific aims are to quantify any errors committed by the participants while installing the car seat and to assess participants' opinions on the car seat's load leg design.
详细描述
A descriptive study will be conducted to determine whether human subjects are able to install the new feature of the prototype car seat correctly. Participants will be presented with the prototype car seat and a set of basic written instructions and labels to guide their installations. The percentage of participants who use the new feature and use it correctly will be reported. Any installation errors on other parts of the child seat (seat belt, lower anchors, top tether) will also be reported.
