Abstract

We are living in interesting times, with the fastest technological development that humankind has ever experienced. The last 200 years have brought us the industrial revolution. People have learned to build machines to release themselves from hard muscle work and from dangerous work. People have developed new technologies that enabled the realization of dreams from the past like the telephone, the car, the airplane, electrical light, or radio and television. And industrialization has enabled the production of enough goods for everyone, so that poverty has a much higher threshold today. Now we are in the middle of the information revolution, which tries to improve our lives through computers. We are using electronic banking, social media, Computer Aided Design and Manufacturing, tomography diagnosis in medicine, smartphones, GPS, notebooks, computer games, and there are many more appearances of computers in everyday life. Currently we are developing smart cities, digital twins, intelligent factories, autonomous cars and more. Our tools include Artificial Intelligence, Deep Learning, fast communication such as 5G, Cloud Computing, Augmented and Virtual Reality, and many others. Digital twins, that are digital representations of real world objects, they are the basis for the simulation and augmentation of scenarios, necessary to provide insight for better human decisions. In this context, Visual Computing plays a central role, as it provides the key technologies to include the human into the decision making processes: - as the interface between computers and people, - as the most efficient channel to transfer data into users via images. Visual computing was also a main driver in developing parallel computing and the GPU. The full potential of visual computing has not yet been exploited in industrial applications, often because real world data are more difficult to handle that clean test data in science labs. Six V’s are the six challenges that we have to cope with in visual data processing: The Volume of data is ever increasing. More and more sensors produce more and more data for more and more computers. The Velocity with which such data is produced is steadily increasing. The Variety of data that shall be utilized is becoming more complex. Not only numerical data, but also categorical data, functions, pictures and videos, complex relations shall be processed. The Validity of available data has to be better checked the more data there are. Are some data wrong? Are data missing? The Veracity of data is the next issue. Where do the data come from? Can we trust the data sources? Are some data manipulated or simply made up? And finally, the Value of our conclusions and results has to be analyzed. Not everything that can be calculated makes the world better. The coping with these 6 V-challenges is essential for the practical utilization of big data. But there is a seventh issue, the Confidentiality of the data. Companies are reluctant to give away their internal data without control who sees or uses them. And people want to maintain some privacy, they want their private data protected, according to data protection laws. Companies like Google or Amazon, but also governments in many countries, store a lot of data about individuals that contradict with such concerns. It must stay one of our most important goals to preserve enough data protection to avoid any misuse of private data. Big data is only a blessing if it is not misused. Our research institute VRVis, together with its Chinese partner VR-KB, works in the field of transferring scientific results from visual computing into valuable and innovative products in industry. International cooperation is a success factor in bringing these fields together. And international conferences such as this one provide the contacts for international cooperation and better understanding between the diverse disciplines profiting from the digitization process.
