Guideline development of mobile phone design for preventing child abuse

Abstract

This paper is studied to develop a guideline of mobile phone design that protects a child from crimes. It is studied that the criminal commits crimes through the three steps of 1) approach, 2) attract, and 3) plunder - movement. Through this research, it was found that the child's recognition of the criminal situation could prevent the child from crimes. Because of limitations of child's cognition, this study is conducted to provide diverse solutions that could notify abnormal signs to the guardians using a mobile phone, even when the child has no awareness of the situation. In addition, the patterns of the child's usual route and walking speed are logged for detecting the criminal situation. This feature enables the guardians to intervene the crime. A design guideline for developing hardware and applications of a mobile phone is suggested through case analysis and expert interviews. © 2011 Springer-Verlag Berlin Heidelberg.
