We investigate tactile representations and haptic interaction that may enable blind people to utilize UML diagrams by using an industry standard editor. In this paper we present a new approach to present tactile UML diagrams by preserving spatial information on a touch-sensitive tactile display. Furthermore we present the results of a fundamental evaluation showing that blind people retain orientation during exploration of tactile diagrams and which problems are associated with the usage of ideographs. We compared our new developed representation with the common method blind people utilize sequence diagrams: non-visually through verbalization. We indicate problems for both representations.
