Internet provides access to huge amounts of data. Every day Internet users add more data through new web pages and social media. But Internet is also expanding as new devices are added. This expanded Internet is often named as Internet-of-Things (IoT). Small, inexpensive computers like Arduino and RaspBerry Pi with their ecosystems of sensors provide new opportunities for generating big data.
The challenge is transforming big data into useful information. Collected data must be aggregated and analyzed, before presented to the users.
The tutorial will discuss the impact of social media combined with new data sources based on sensors. How can such data be aggregated, analyzed, combined and visualized to create value for the users? The tutorial will include some practical examples from completed and ongoing projects.

A Primer on User-Centered Mobile App Design
Prof. Dr. Stephan Böhm, RheinMain University of Applied Sciences - Wiesbaden, Germany
Today, the most popular mobile app stores offer more than one million applications. Mobile applications are available for almost any situation and all aspects of life. But apps are more than just a piece of software. They can be used to personalize a smartphone to the user specific needs and preferences. However they need to meet these user needs and preferences in an environment characterized by high levels of distraction, low awareness and short user sessions. For this reason the development of a successful mobile application requires a user-centered design approach.
User-centered app design begins with up-front user research to identify user requirements and define the overarching concept for the given mobile application. The next step is then to create an app prototype that can be used to acquire user feedback and to continuously improve the concept. Mobile developers can choose from a large variety of prototyping tools today. The choices range from simple paper prototyping approaches based on paper and pencil to comprehensive software suites enabling the definition of complex screen flows and high-fidelity prototypes. Those high-fidelity prototypes provide a very realistic look and feel of the intended application without the need to write a single line of code.
Against this background, this tutorial aims to give a short introduction into the app ecosystem as well as the process and tools for defining user-centered mobile application concepts. The focus is from the app idea to a high-fidelity prototype prior to the actual software development process. The tutorial contains some live demos of popular tools that can be used for mobile prototyping. Target group of this tutorial are conference participants new to this field but generally interested into the user-centered design approach for mobile applications.
