Walking-while-texting on mobile phones has become a large social problem because conflict accidents with other people frequently occur in the traffic areas such as the station yards. Applications to prevent the walking-while-texting have already been launched, but they do not seem to be used commonly. In this paper, we have considered two new view points, an internal factor of screen watching and an external factor of environmental risk conditions in referring to the knowledge obtained by the group interview. We have developed a new system to timely alert to the walking-while-texting user by using a smartphone application and environmental measurement sensors. As a result of comparison of the proposed system to the application officially provided by NTT docomo, we successfully achieved the application efficiency, the effect of prevention of walking-while-texting, improving momentary user experience and raising intention to use.
