【 摘 要 】

For the visually impaired it is important to learn about different kinds of spatial knowledge from non-visual maps, specifically while walking via mo- bile devices. In this article, we presented an augmented audio-haptic You-are- here map system based on a novel pin-matrix device. Through the proposedsystem, the users can acquire not only the basic geographic information andtheir location, but also augmented accessibility attributes of geographic featuresby user-contributed annotations. Furthermore, we at the first time discuss theannotation taxonomy on geographic accessibility, towards building a systemicmethodology.
