چکیده

Tactile maps are important substitutes for visual maps for blind and visually impaired people and the efficiency of tactile-map reading can largely be improved by giving assisting utterances that make use of spatial language. In this paper, we elaborate earlier ideas for a system that generates such utterances and present a prototype implementation based on a semantic conceptualization of the movements that the map user performs. A worked example shows the plausibility of the solution and the output that the prototype generates given input derived from experimental data.

Verbally Assisted Virtual-Environment Tactile Maps: A Prototype System

Tactile maps are non-visual substitutes for visual maps for blind and visually impaired people. In [3, 11] we suggested to increase the effectiveness of tactile maps by developing a system that generates assisting utterances to facilitate knowledge acquisition. The utterances are inspired by a corpus of assisting utterances given to tactile map explorers by human assistants. The tactile maps ar...

Verbal Assistance in Tactile-Map Explorations: A Case for Visual Representations and Reasoning

Tactile maps offer access to spatial-analog information for visually impaired people. In contrast to visual maps, a tactile map has a lower resolution and can only be inspected in a sequential way, complicating the extraction of spatial relations among distant map entities. Verbal assistance can help to overcome these difficulties by substituting textual labels with verbal descriptions and offe...

Ereigniserkennung während der Exploration linien-basierter Graphiken in virtuellen haptischen Umgebungen

Haptic representations offer access to graphical information for blind and visually impaired persons. Haptic perception requires active explorative movements, making haptic perception, in contrast to visual perception, sequential and local. In order to improve the information gain during haptic exploration and to compensate its limitations additional information can be conveyed in the auditory ...

Situated Utterances and Discourse Relations

Utterances in situated activity are about the world. Theories and systems normally capture this by assuming references must be resolved to real-world entities in utterance understanding. We describe a number of puzzles and problems for this approach, and propose an alternative semantic representation using discourse relations that link utterances to the nonlinguistic context to capture the cont...

A Prototype Audio-Tactile Map System with an Advanced Auditory Display

Tactile surfaces can display information in a variety of applications for all users, but can be of particular benefit to blind and visually impaired individuals. One example is the use of paper-based tactile maps as navigational aids for interior and exterior spaces; visually impaired individuals may use these to practice and learn a route prior to journeying. The addition of an interactive aud...
