Participation at the AK GIS LKT Baden-Württemberg in Heidenheim


On 20th April 2023, the 52nd meeting of the working group GIS of the Landkreistag Baden-Württemberg took place in Heidenheim. The event serves the exchange of the different districts of Baden-Württemberg in the field of geoinformation systems with regard to current problems and approaches to solutions. In addition to the pure exchange, there were also several presentations on various topics in the field, whereby the AccessibleMaps project participated with a presentation on the topic of “Accessibility in Maps”. In this presentation, solutions developed in the project were presented to the participants and possible fields of use of accessible map applications on the communal level were discussed.

Participation at FOSSGIS 2023


At the current FOSSGIS 2023, on the one hand, project results were presented in the context of a lecture on the topic „Digitale Kartendaten für alle“. On the other hand, we participated in the expert meeting „Indoor OSM“ in order to exchange information with representatives of different fields of interest in this area, as well as to network with other mappers and developers interested in the topic.

Online Indoor Tagging Meeting 2023


Following the Indoor OSM 2022 Working Meeting in Frankfurt am Main, an online meeting was held on February 14, 2023, to discuss the problems. The results of this meeting can be found under the following link:

Indoor OSM 2022 Working Meeting


From October 14 to 16, 2022, a working meeting on the topic of indoor mapping in OpenStreetMap took place in Frankfurt am Main. The event, which was supported by the FOSSGIS e.V. association, was aimed to the target group of mappers and developers who are active in the field of indoor mapping in OSM and was attended by two employees of the TU Dresden. The topic of the event was the adaptation and extension of the Simple Indoor Tagging format in OpenStreetMap, which is used to map buildings. In addition to the consideration of current problems from different perspectives such as 3D rendering or detection of barriers, solution proposals were developed and the further procedure for implementation and networking was discussed. A summary of the meeting can be found under the following link:

Survey for the evaluation of object sounds (auditory icons)


Dear prospective participants,

We would like to invite you to a survey that evaluates 40 auditory icons created by us. These are sounds for everyday “objects”, such as obstacles, stairs, people, bicycles or bathrooms. The study is primarily for people with blindness or mobility impairments, but we also encourage people without any disability to participate. Participation is open until November 30, 2022. It will take approximately one hour to complete the questionnaire. We would greatly appreciate it if you could pass the questionnaire on to people with blindness or mobility impairments in your circle of acquaintances.

You can find the survey at the following link:

We thank you in advance for your participation. Your answers will be stored anonymously, treated confidentially and not passed on to third parties. The results will be used exclusively for scientific purposes. At the end of the survey you have the chance to win one of five Amazon vouchers worth 25€ each.

Presentation of Results at the LNdW and the Output


The Long Night of Science in Dresden and the Output of the Faculty of Computer Science at the TU Dresden invite interested citizens to participate to current research results every year. This year, the opportunity was used to present the current results of the research project as part of a project showcase. The presented prototypes included the developed web application, which addresses people with visual and mobility impairments, tactile printed indoor maps and the possibility of displaying dynamic tactile maps on a pin-matrix device.

FOSSGIS 2022 Lecture and Panel of Experts


As in the previous year, current results of the project were presented and discussed at FOSSGIS 2022. On the one hand, we explained options how to collect accessibility information in buildings as part of a lecture. On the other hand, there was a panel of experts on the subject of “accessible indoor maps”, which was used to discuss and exchange knowledge. A video of the lecture is available at

AccessibleMaps at the ICCHP

AccessibleMaps is represented at this year’s ICCHP conference with eight scientific publications that have been produced as part of the project. The following papers are presented in the special thematic session “Digital solutions for inclusive mobility: solutions and accessible maps for indoor and outdoor mobility”.

  1. Split It Up: Allocentric Descriptions of Indoor Maps for People with Visual Impairment
  2. Expert Study: Design and Use of Textures for Tactile Indoor Maps with Varying Elevation Levels.
  3. Atim: Automated Generation of Interactive, Audio-Tactile Indoor Maps by Means of a Digital Pen.
  4. An Audio-Tactile System for Visually Impaired People to Explore Indoor Maps.
  5. Supporting Independent Travelling for People with Visual Impairments in Buildings by Harmonizing Maps on Embossed Paper and Pin-Matrix Devices for Accessible Info-Points.
  6. The Accessible Tactile Indoor Maps (Atim) Symbol Set: a Common Symbol Set for Different Printing Methods.
  7. Indoor Navigation Assistance for Visually Impaired People via Dynamic SLAM and Panoptic Segmentation with an Rgb-D Sensor.
  8. Accessible Adaptable Indoor Routing for People with Disabilities.

We are very pleased to present and discuss the diverse results from the project to an international community.

Comprehensive Study to Evaluate the Design of Tactile Indoor Maps


A study on the evaluation of tactile indoor maps is currently taking place at the TU Dresden, for which more than 50 interested people with blindness or visual impairment have already registered. The participants receive tactile materials by mail, which they subsequently have to evaluate within an online questionnaire. Currently, the first envelopes are being mailed to participants. The results of this study will enable us to obtain a comprehensive picture of the design and use of tactile indoor maps on swell paper and in embossed printing.

Registration for participation in the study is still possible. If you are interested, please contact Christin Engel at

Special Thematic Session at ICCHP-AAATE 2022


At this year’s ICCHP-AAATE international conference, we will have a special thematic session on digital solutions and accessible maps for indoor and outdoor mobility. Submissions for this special session have to follow the standard conference submission process. More information can be found on our page at the ICCHP-AAATE

Second Meeting of the Advisory Board of the AccessibleMaps Project


The second meeting of the Advisory Board of the AccessibleMaps project was held on 01 October 2021. The meeting was attended by fifteen people from the advisory board and nine project staff. Also in the second year, due to the pandemic, the meeting was held virtually. This year the topic was the work of the second year of the project. Thereby, the two work priorities “From building plan to OSM maps” and “From OSM maps to users” were presented. The current status was shown on the basis of various demos. In a subsequent discussion, questions and suggestions were discussed together.
