SmartMMI with Technical Visit at IT-TRANS 2022

the highlight - a technical visit in SmartMMI train and lab

The highlight of our exhibition for visitors was the Technical Visit on Thursday, May 12, 2022, from 2:00 to 4:00 pm. The SmartWindow technology installed in the SmartMMI vehicle was presented during a joint trip on the SmartMMI train to Karlsruhe University of Applied Sciences. In the laboratories of the HKA, the participants were given an insight into the iterative development process of the SmartWindow using various prototypes.

In the IUMS laboratories, further innovative interaction technologies as well as current student projects in the field of digital mobility were shown. The aim is to demonstrate and develop contacts, joint projects and further points of contact between science and industry. Further information can be found in the press release “impressions into the mobility of tomorrow” of the HKA.

Hands On Research – SmartWindow now active for all passengers

experience research live - the intelligent light rail window is now open to all passengers!

A window that not only provides a view of the passing landscape, but also offers passengers interactive timetable data, route network maps and info on places of interest: This is by no means science fiction, but is called “SmartWindow” and can now be tested in a light rail of the Albtal-Verkehrs-Gesellschaft (AVG) by all interested passengers. Live research is taking place in Car 900 as part of the SmartMMI project, which is being led by Karlsruhe University of Applied Sciences. The project is funded by the German Federal Ministry of Digital Affairs and Transport. AVG is one of the five partners in the SmartMMI project and is supplying the appropriate carriage material for the exciting field test.

SmartMMI Closing Event

On Friday, February 25, 2022, the successful final event of our #SmartMMI project took place.🥳 We would like to thank all participating partners: ANNAX Schweiz AG, Albtal-Verkehrs-Gesellschaft mbH, MENTZ GmbH and USU Solutions as well as the associated partners: Karlsruher Verkehrsverbund KVV, HÜBNER Group, DB Engineering & Consulting and Alstom for the great cooperation, the numerous interests and the positive feedback!🤗 Funded by #mFund and #BMDV.

P.S. The SmartMMI field test is still ongoing. On behalf of the SmartMMI team, we cordially invite everyone to participate. Here you can find more information about the SmartMMI field test, the registration for the SmartMMI user study as well as the current location of the SmartMMI-train.

Final Meeting of SmartMMI Project

SmartMMI- Closing Event

After a three-year project duration, the SmartMMI project entered the final field test in summer 2021. After a six-month field test, the final event will take place on Friday, February 25, 2022. At the online event, the contributing project partners ANNAX, AVG, IUMS MENTZ and USU will present the project and the results achieved to the public in more detail.

SmartMMI pursued the goal of improving the supply of information to passengers along their mobility chain. To achieve this, the consortium focused on researching and testing the context-sensitive provision of mobility data on specially developed intelligent transparent display panels. The prototype innovative display panes were installed in a vehicle of the Karlsruher Verkehrsverbund and field-tested with KVV passengers in conjunction with the SmartMMI mobile application.

To participate in the final meeting, registration via e-mail ( is required. Registered participants will receive the access data for the ZOOM web conference.

Project vision as well as further project information about the research project SmartMMI summarized in the SmartMMI project video.

More information on the implementation of the currently ongoing SmartMMI field test.

Demonstration of SmartMMI Fieldtest Results

Presentation of the SmartMMI results

During a ride with the SmartMMI streetcar on 08 February 2022, we presented our semi-transparent display to interested representatives of the Albtal-Verkehrs-Gesellschaft (AVG). The SmartMMI project aims to provide passengers with better information during their train journey. To achieve this, the project consortium focused on researching and testing the context-sensitive provision of mobility data on specially developed intelligent, transparent display discs. The prototype display panels were installed in a vehicle of the AVG six months ago. Since then, this vehicle has been on the road in the KVV network. The display screens could thus be field-tested by passengers in conjunction with the mobile SmartMMI application.

Your curiosity is piqued and you would like to learn more about our research project? Then feel free to register for our online closing event on Friday 25.02.2022. Here you will get exciting insights into the SmartMMI research project from us and the participating partners. More information about the SmartMMI final meeting.

Intelligent light rail window enters field test!

Research results on the SmartMMI project under the leadership of HKA are made available to the public

One glance at the light rail window – and the passenger is already informed about both the passing museum and his or her connection. This information will be displayed on the future semi-transparent display window, the SmartWindow. What sounded like science fiction in 2017 has largely become reality in the SmartMMI research project led by Karlsruhe University of Applied Sciences (the HKA) – in a dual-system light rail vehicle operated by Albtal-Verkehrs-Gesellschaft mbH (AVG).

In the currently ongoing field test, the SmartMMI system developed in the project is being tested in consideration of the specifications for the corona pandemic. For this purpose, the SmartMMI app was made available to the public and the SmartWindow was installed in a dual-system light rail vehicle of the AVG. Passengers can interact with the SmartWindow and have desired information displayed on the window, for example the route network map, connection information, or points of interest along the rail route, insofar as these have already been included in the SmartMMI system in terms of data.

Within a six-month field test phase, the applications will be evaluated until spring 2022. The aim of these user studies is to find out in which situations and under which circumstances passengers interact with the SmartWindow. They will thus provide information about the potential and future viability of such interactive passenger information systems.

SmartMMI project results summarized at a glanze

The video shows the project idea, current project results and the prototypical implementation of these results in the railroad simulator. Currently the following services are available for application:

  • displaing of the current position, the next stops and which connections are reached,
  • calculation of the route via the map view or via the route network plan,
  • transferring the personal travel plan from the passenger’s SmartMMI app to SmartWindow and taking a connection created on SmartWindow with them.

Currently we are developing Augmented Reality applications. Semi-transparent displays provide the possibility to show information about surrounding sights, such as the pyramid on the market place and the Karlsruhe Castle, while passing by. This way, current exhibitions and events as well as offers in retail can be displayed. But just take a look for yourself…

SmartMMI presented on virtual IT-TRANS 2020

The SmartMMI research project “Model and context-based mobility information on smart public displays and mobile devices in public transport” was presented at the virtual trade exhibition IT-TRANS 2020 as part of a round table on December 3, 2020. In addition to the project presentation and the presentation of conducted user studies and their results, a lively discussion took place on how semi-transparent display panels can be used to strengthen the local retail trade. The international trade exhibition and conference took place between December 1 and 3 for the first time in online format. For all those who could not be there live, please find a video of the presentation below.
