Yeevon Ooi of Webcredible writes in a long article that designing interactive products for children shouldn’t be any different from any user-centred design process, but the methods for carrying out user research, the implementation of different design guidelines and evaluating the products need to cater for the young or little audience group.
“Designing for children requires careful planning depending on the nature of the project and the age-group of the children involved. Always determine the age-group of the target audience and use appropriate methods for conducting user research, implementing design guidelines and evaluating the designs. Lastly, a good designer must never forget the ethical considerations involved while designing for children and should exercise their limits accordingly.”
