AI and accessibility: How cloud-based solutions with AI already contribute today’s Accessibility.

Presentation of “hybrid models” that works together with Artificial Intelligence to allow a human correction. Smart features such as the learning of the AI from individual dictionaries or technical jargon also help companies and authorities to use them. What will the future bring and what will the trends look like? Live subtitles can be received directly on your device, independent of device, browser or OS. Viewers can also use live translation. The result is that every speech, lecture and event is accessible to foreign language speakers and the deaf and hard of hearing.

Functional Programming and Domain Driven Design – a dream team!

Many concepts that play a role in Domain Driven Design can be implemented very easily with functional programming. This includes for example

* Hexagonal architecture
* Description of invariants
* Stateless services

Examples in functional languages as well as classical languages – functionally used – show how many concepts of Domain Driven Design can be implemented elegantly and effectively. A look at the integration in classical languages and architectures offers the opportunity to actually use these techniques in practice.

Incremental & Iterative

Developing and delivering projects and products in ever shorter cycles has now become established in IT. Other areas of our economic life are also characterized by the procedure of gradual / adapted delivery. Lean production in industrial manufacturing and design thinking are two examples of many who choose the process model that can be compared with agile software development, Scrum or Kanban. The lecture clarifies what unites these procedural models and what differences the different areas of application have brought about. The Audience should get tools to better assess current hypes and develop a better sense of the naturalness of these methods.

EmergencyEye, a WebRTC technology for barrier-free

An accident, a broken coffee maker, an insurance claim –
EmergencyEye enables barrier-free communication with service centres without annoying pre-installations on the smartphones. Using EmergencyEye technology, callers can call the normal service number, identify themselves as speech or hearing impaired using tone dialling, start a chat immediately and share live video with staff. This makes common service hotlines intuitively usable for everyone. In addition, the chat can be simultaneously translated into all common languages and thus also breaks down barriers with foreign speakers. All callers simply dial the default phone number and the staff member activates the software from the switchboard as needed.

SIGNS – Video based recognition of Sign language

Language assistants use natural language processing to decode and respond to audible commands. In other words, no sound means no response. SIGNS closes the gab between Hard of Hearing and language assistants. You can now use the Voice Assistants for the first time. The innovative smart tool is reinventing the voice, which voice technology is much more than just a sound.

SIGNS recognizes and translates sign language and communicates with any language assistant. International brands are also implementing SIGNS in their products.
This lecture shows the concepts and technology behind it.

IT modernization is not possible without cultural change

In order to adapt to the ever changing market requirements and to provide flexible and modern IT for every user. The role of IT has to be completely reinvented. The key to success is the collaboration between departments and IT on a level playing field. The needs-based solutions will only be found in close cooperation. We will need to break away from our “antiquated customs” and improve ourselves for the future. All of this requires an open and appreciative corporate culture. In her presentation, Petra Jaschhof speaks on her experiences and the role of “diversity” and “inclusion”.

Are Signing Avatars ready for real world situations?

There has been much publicity on claims that avatar technology can replace human interpreters. This presentation will analyze the current state of avatar technology and discuss its potential for effective applications in todays world. The 2018 WFD/WASLI statement on signing avatars describes acceptable possibilities, but some projects claim greater breakthroughs in automatic spoken-to-sign translation. This talk will give an overview of signing avatars and discuss their strengths and weaknesses, with particular emphasis on the suitability in the settings mentioned in the WFD/WASLI statement.

Breaking communication barriers between deaf & hearing people

Is it possible to break communication barriers between deaf and hearing people? Is it possible to provide the communication with total privacy? Is it possible to reduce human sign language interpreting costs? Yes it is! SLAIT offers Sign Language translation from any device in real time and without the need of any additional hardware. This is possible thanks to our neural network Artficial Intelligence approach.

In this talk we will explain the current state of our solution, evaluation of development and what are the possible paths to take in the future.

The Communication disrupter

Communication concerns everyone who aspires to a higher level of education. Despite the difficulties, more and more deaf people are studying in Germany. In order to react to these particular problematic communication situations, a technical prototype was designed at the TU Munich. This prototype calculates our speech speed and volume. It sends a loud feedback if one of the participants talks too fast or too loudly or if they interrupt each other during the conversation. In this way, the interferer allows people to communicate with each other again at eye level.

Music for deaf people

Music was and is important for all societies. It is one of the most beautiful ways to experience feelings. A widespread misconception is that deaf people are unable to experience joy in music.

We have developed a portable body subwoofer that allows audio signals to be felt in the form of structure-borne sound. By perceiving the bass in the upper body, the user experiences an unusually authentic sound experience. And this completely silently for his environment.

deep.one emerged from a research project of co-founder Frederik Podzuweit, who published a first design. As a result of the high demand from deaf people worldwide, he developed the product.

In addition to music, all other audio-visual entertainment content from films, gaming and VR/AR can be intensively experienced. Hearing impaired as well as hearing people are equally enthusiastic. Frederik talks about the history of the company, the challenges in product design and prototype development as well as the first steps in building the company.

Domain-driven Design in Practice – Understanding the Domain with Event Storming

Domain-driven design means: Good software originates from the domain. Event storming is a modern analysis technique to bring developers together with the experts of the domain Together we look at concrete stories from the working world and learn what is really important for the experts and how their workflows works in practice. The great thing is: the event storming already gives us concrete hints for the software architecture and implementation. And event storming is also a lot of fun.

In this talk I tell you how event storming works and how we use it in practice. In the following workshop the participants do a real event storming together with me.

„Event Storming in Practice – Understanding Specialist Processes Using the Example“

Event Storming helps us to understand specialist processes and to build perfect software for them. In this workshop we analyse a professional process from the domain “cinema”: How should a perfect cinema ticket sale for deaf people look like?
The participants tell an exemplary story in two groups. With all the exciting details they find important. We write down the events of these stories on small sticky notes, which we arrange and group. At the end of the event storming we are real experts and have a very concrete idea how to build our cinema software.

Truffle framework with GraalVM

A couple of years ago, Java was still the dominant language on the JVM and could do whatever one wanted. Later, a few scripting languages were added, such as Jython and JRuby. And the new compiled languages like Scala and Kotlin heralded the era of polyglot programming. The Truffle project associated with GraalVM now promises to make it even easier to interlink languages that are not the actual JVM languages with the ecosystem.

Modern, barrier-free eLearning for deaf people

Language is one of the key tools in everyday and professional communication. In an effort to give deaf people a fair chance to enter the labour market, we see the need to create new learning opportunities for our trainees. They are modern, low-threshold, barrier-free (for the deaf people), flexible and location-independent. Our eLearning tools focus on sign language, images support access to the text. A visually clear design, a reference to reality and classic game features promote the motivation to learn.
