d-SIRE develops first fully accessible platform for social and volunteering activities in Germany

Aktion Mensch's volunteer brokerage service is making a huge leap forward: Its database, which has existed since 2008, has been fundamentally updated and expanded into a comprehensive platform.

The new volunteering platform has been online on Aktion Mensch's web portal for several weeks now. But not only there: The entire application can also be integrated by partners free of charge on external websites, for example by regional volunteer agencies. By means of a simple configuration, they can even adapt the design and functionality of the application to their individual requirements and respective corporate designs.

During the project, numerous workshops were held with experts from volunteer brokers as well as with active volunteers. This has helped to ensure user acceptance by both target groups from the very beginning.

As part of the project, d-SIRE was involved in consulting, UX concept and design, as well as being responsible for the entire technical implementation of the frontend and backend. The application was implemented in the Microsoft Azure Cloud and offers APIs for connecting external services.

Digital accessibility is of great importance to Aktion Mensch. For this reason, not only the public website, but also the closed area for the administration environment was implemented in full conformity to WCAG requirements.

Stolpersteine Deutschland – an App against Oblivion

An app to commemorate people who must never be forgotten: In conjunction with the "Stolpersteine" (stumbling stones) art memorial, we would like to digitally support the culture of remembrance for the victims of National Socialism.

To do this, we use and compile publicly available data from the online encyclopedia Wikipedia and OpenStreetMap. The personal stories and fates are thus made directly accessible at the places in Germany where they were written. Already at launch, more than 20,000 Stolpersteine are available in the app. More will be added by us on a regular basis.

The largest decentralized memorial in the world: "A person is not forgotten until his name is forgotten," Gunter Demnig quotes the Talmud. To commemorate the victims of the Nazi era, the artist inserts small brass memorial plaques into the sidewalk in front of their last self-chosen place of residence or work. Demnig began with a first stumbling block in 1992, and there are now more than 80,000 in over 1,000 German communities and 21 countries. The art project is considered the largest decentralized memorial in the world and focuses on the people who were persecuted, murdered, deported or expelled during the Nazi regime.

Taste & vote – with our App for the Wine Festival

"In 80 days around the wine" is the motto of this year's wine festival in Koblenz. The festival invites all wine enthusiasts to get to know the regional wine-growing regions as well as that of the guest region Wachau from Austria. The app, developed by d-SIRE, offers extensive content about the festival wines, winemakers and wine regions and provides daily updated information and dates for the numerous events. In addition, visitors can vote for their personal "Wine of the Day" and win attractive prizes.

The election of the "WeinKaiserWein" is the highlight of the event, which takes place over the entire festival period: the wine that has particularly captured the hearts of festival guests is nominated via the app's voting tool. After the unveiling at the closing event, this wine may ceremoniously bear the award "WeinKaiserWein 2022" until the next wine festival.

You can download the free app in the iOS App Store and in the Google Play Store.

AOK extends accessibility consulting mandate

We are very pleased to have also succeeded in winning the AOK's second Europe-wide tender with regard to digital accessibility, with which we can now continue the successful collaboration that began in 2019 through 2025.

With an expanded scope of services, we are now consulting - in addition to the AOK Federal Association - all eleven regional AOKs and will again carry out numerous audits of websites and apps as part of this mandate. In addition, we are supporting the teams of the health insurance company in increasing the accessibility of online offerings through Plain Language and videos in German sign language.
