“…Those characteristics that result in a high degree of readability and efficiency in the production and use of tactile maps were also identified. As it turned out the material of the maps is a matter of personal preference and tactile maps should be available to students in a variety of formats to meet individual needs [5], [6]. B.…”

Until recently, the medical model of disability has dominated, but times and views change so that the model of social inclusion is now the guideline. It is therefore the broad acceptance of the social model of disability that leads to these changes and assistive technology is the main tool that allows social inclusion. In this paper an attempt is made to investigate greek and international bibliography regarding the design, the use and the effectiveness of haptic maps. This bibliographic research is divided into two main parts, each of whom divided into sub-chapters. The first part includes definitions and researches related to the structure, form and operation of the tactile maps and, more generally, of the individual characteristics taken into account in their creation. In the second part, there is a brief presentation of the new technologies for the blind and visually impaired people.

“…To realize this, the research results of user studies carried out to address these questions (e.g., References [4,7,58]) have to be transferred to formal rules for computing functional and usable maps. Likewise, for volumetric tactile material, there is an increasing number of publications (e.g., Reference [17]) that could help to optimize the usage of multiple elevation levels (such as sketched in Section 3.1) for tactile map design. This has to be done with current and upcoming technologies in mind.…”

Tactile graphics play an essential role in knowledge transfer for blind people. The tactile exploration of these graphics is often challenging because of the cognitive load caused by physiological constraints and their complexity. The coupling of physical tactile graphics with electronic devices offers to support the tactile exploration by auditory feedback. Often, these systems have strict constraints regarding their mobility or the process of coupling both components. Additionally, visually impaired people cannot appropriately benefit from their residual vision. This article presents a concept for 3D printed tactile graphics, which offers to use audio-tactile graphics with usual smartphones or tablet-computers. By using capacitive markers, the coupling of the tactile graphics with the mobile device is simplified. These tactile graphics integrating these markers can be printed in one turn by off-the-shelf 3D printers without any post-processing and allows us to use multiple elevation levels for graphical elements. Based on the developed generic concept on visually augmented audio-tactile graphics, we presented a case study for maps. A prototypical implementation was tested by a user study with visually impaired people. All the participants were able to interact with the 3D printed tactile maps using a standard tablet computer. To study the effect of visual augmentation of graphical elements, we conducted another comprehensive user study. We tested multiple types of graphics and obtained evidence that visual augmentation may offer clear advantages for the exploration of tactile graphics. Even participants with a minor residual vision could solve the tasks with visual augmentation more quickly and accurately.

3D models are an important means for understanding spatial contexts. Today these models can be materialized by 3D printing, which is increasingly used at schools for people with visual impairments. In contrast to sighted people, people with visual impairments have so far, however, neither been able to search nor to print 3D models without assistance. This article describes our work to develop an aid for people with visual impairments that would facilitate autonomous searching for and printing of 3D models. In our initial study, we determined the requirements to accomplish this task by means of a questionnaire and developed a first approach that allowed personal computer-based 3D printing. An extended approach allowed searching and printing using common smartphones. In our architecture, technical details of 3D printers are abstracted by a separate component that can be accessed via Wi-Fi independently of the actual 3D printer used. It comprises a search of the models in an annotated database and 3D model retrieval from the internet. The whole process can be controlled by voice interaction. The feasibility of autonomous 3D printing for people with visual impairments is shown with a first user study. Our second user study examines the usability of the user interface when searching for 3D models on the internet and preparing them for the materialization. The participants were able to define important printing settings, whereas other printing parameters could be determined algorithmically.
