MaxiTaxi – the app for taxi drivers and employers


In our group we have looked into the needs and problems of the modern taxi driver and have addressed these in our cleverly engineered smartphone app. We have discovered a lack of proper organization and information, which both are fundamentally important to a pleasant working environment.

Our problem-solving approach to this situation is an easy to use app that covers two different aspects. Not only do we integrate different organization tools like a smart shift schedule tool that supports the employer and the driver likewise by giving them access to a digital planning platform. This gives the user the advantage of being able to plan without the necessity of having a time consuming phone call or annoying, old fashioned paperwork.

Furthermore we offer the taxi drivers an interactive function to guide the user through the process of writing an accident report or signing up for specific taxis. The benefit of our solution is that everything is saved into a database so all of the information can later be reviewed by the drivers and the employers so no information is lost like in the old days before our app.

A more fun side of our app is that we offer the drivers not only a challenging but also an informing quiz section. Our previous research has shown that long waiting times of up to two hours are a huge part of the everyday work. With our quiz we provide them a useful activity during their waiting times.

Our future aim is to appeal not only to the drivers and the employers, but also to the passengers by giving them a way of effortlessly paying for their drive without the need of cash or credit card.

Concept Development 2015 – The second week


The second week started off with some powerfully performed elevator pitches, summarising the need, the approach, the benefit and the competition of the developed concepts. Next, Kalle and Alex introduced scenarios and storyboards – two design tools that help to nail down and communicate a concept. The storyboards are now the basis of our videoprototypes.

Concept: MaxiTaxi

In the last days we analysed our interview data in several steps by using concept tools like HMW-Questionsspecified needs to focus on and came up with a set of creative ideas to fullfill these needs. 


There are 53.000 taxi drivers in Germany, organised in small companies with up to 20 drivers. The smaller the company, the smaller the budget to manage and support their drivers, which can lead to a lack of communication. On that link we decided to step in.

With the help of further designing tools like Scenarios and Storyboards we refined our different approaches. We agreed on developing a mobile and desktop application to improve the communication of information between taxi drivers and their companies and to simplify organization structures. We want to give the opportunity to manage matters like stratifaction in a
digital way and imagine to convey relevant information for the drivers work day in a playful manner.

First week in Concept Development – Group 7 – Design Process

Group 07, Uncategorized

designProcess1The next step of the process was the analysis of the data we collected in our user research at the helpdesk. We considered the different aspects and collected them in an affinity diagram. Afterwards we tried to find the „How might we…?“ questions and came to the conclusion that especially the communication and the working atmosphere is improvable.

Later than we brainstormed the opportunity of one of our HMWs. In the presentations in front of the other groups we got some great feedback for the most useful draft in order to develop the communication lacks for our target group.

All the collected information leads us to the conclusion that one possibility to eliminate the grievances of the helpdesk would be the innovative “Happy Glasses”. Some of its features are meetings with face-to-face communication, popup reminders on the glasses, wall presentations and many more.

Now we are improving our storyboard in purpose to create a video prototype.


The BattlePad


It’s done.

The BATTLEPAD is our solution to many of the needs of our selected user group – the Volunteer Fire Department of Neubiberg (special thanks to them for the amazing collaboration).
For everyday operations, firefighters depend on quick access to vital information like car blueprints, identifying hazardous materials and organizing units.
In the recent years, modern equipment like tablets were introduced to facilitate those tasks during the line of duty, without having to rely on comparably slow and bulky laptops or even fallback options like filing folders. However, due to their fragile nature they usually aren’t used on the forefront of operations.

With our concept, it is much more convenient to bring the desired information to the firefighters on the scene. Shock-absorbant, waterproof, heat resistant, with enhanced battery life, adherent on magnetic surfaces and usable in full protection gear with special glove extensions upgrade.

The BATTLEPAD is eager to face many unsafe environments.




Readify is a smartphone and desktop application designed for volunteer firefighters. It helps to coordinate and organize forces needed. Readify notifies the firefighters – they are then able to confirm whether or not they are coming to the fire department. The coordinator in the fire station is able to live-track the firefighters.
Main features:
– Information about the operation (e.g. house fire)
– Number of required firefighters
– Number of arrived firefighters
– Map-Tracking


We’ve been to the local police department. From the base of our research we developed a new concept for a handhold radio communication interface.
We discovered the following main problems:

* finding the right target in a list, e.g. the right frequency group,
* finding the right functions in a menu structure with high complexity and
* getting the current status of the system right.

From that we focused on the structure of the main menu.
We designed a few different functions for the interface of our so called PoliFon – a police radio communication system:

* a shock-resistant hardcase with a built-in touchscreen of high robustness,
* a long-life battery,
* a function to search all functions and contents from the main menu and
* fast access buttons on the left side of the hardware, next to the push-to-talk button to
manage the display lightning, sound and profiles

This invention leads to following benefits:
* less teaching courses,
* fast access in cases of emergency and
* handling without previous knowledge.

After analyzing and organizing the data we gathered during our User Research at the Police Department it became apparent that the most common problem of the policemen are complicated interfaces that are hard to use especially during dangerous situations.

That’s why we focused our work on designing the “PoliFon” – a device close to a Smartphone that isn’t just generally easy to use but also presents the most important features so quickly accessible that everyone can find them even under the high pressure that policemen often have to deal with during precarious operations.

The “PoliFon” also simplifies the communication of new operations between the headquarters and the officer as it presents additional information such as the location and the type of the incident on the screen. This way the policeman is informed faster and misunderstandings can be avoided.

Concept: “POLARES”

Group 11, Uncategorized, WS1314

After our user research, we began to analyze and evaluate the collected data. By using different methods, we came to the conclusion, that organization and administration is the main area we wanted to focus on. Especially lack of synchronization and redundant recording of data were aspects, which in our opinion needed to be improved.

In return, we decided to develop a uniform system that collects data consistently from every unit of a typical police process and synchronized that data.

Instead of multiple data entries, POLARES creates the possibility to capture data already on the road. This goal is reached by using different input masks for different cases, which are partly pre filled by the system and are very easy to be completed.

easy, reliable, modern – POLARES is the tool of the police of tomorrow already today.


Concept: Little PEA


While trying to save your life, paramedics have issues handling multiple devices for communication and data transfer. Some of them are not accessible, others are huge handheld devices that require your full attention.

Little PEA sounds small, is small and saves valueable time and space in critical situations. This wearable device combines pager and radio communication, and allows the collection and transmission of patient data. It integrates nicely with the infrastructure that is currently in use, especially pre-registration of stroke and heart attack patients. Due to its compact format and the quick and easy handling, Little PEA improves the working conditions in critical situations.
Time is not always money. Little PEA might save your life.
