DNA: Web-based content posting interaction in pervasive display

In the case of natural disaster, there is a need for an integrated information presentation system. The increasing number of public display could be used as a medium for that system. But currently, public display is developed as a closed system. Where only display owner could post content on it. It needs to move to a more open system that allows people contribution beyond display owner. In this paper, we proposed an interaction flow that could foster posting content activity in a system called DNA (Digital Notice Area). We tried to be similar to posting content activity in the traditional “Public Notice Areas”. From our preliminary research, we found that our proposed interaction has a SUS score of 69.25. Which means that it is acceptable but still need improvement.
