Abstract: Software is omnipresent. It is key to successful businesses and has become key to our social activities. As many systems, also software systems need to change in order to stay successful on the market. However, these changes cause software systems to become larger in size and more complex as described by Lehman’s Laws of Software Evolution. As a consequence, more resources are needed to maintain, or in general, evolve a software system. Evolving software systems is therefore mastering change and system complexity. The goal of my research and teaching is to provide software engineers with means to master this challenge.

In this inauguration lecture, I outline several challenges of evolving software systems and present the ideas and findings from my recent research to address them. In particular, I show how we can use the history of software projects to identify critical parts of a software system and how we can use visualization techniques to help software engineers to understand the implementation of large, complex software systems including large spreadsheets.

Abstract:

The use of software development methods (SDM) in software industry proves beneficial as it contributes to higher quality of both, the process and its product, i.e. the developed software. Despite these evident benefits, the studies on the maturity of the software development discipline show that a large percent of software development companies do not have their SDMs documented and those that have, do not really follow them or do not follow them rigorously. This problem has been recognized as one of the key reasons for failures in software development projects and a contributor to the low quality of software. In this talk I will introduce a novel approach that could help to improve the maturity of software development processes. The approach is based on the method engineering principles taking into account the limitations that hinder its use in practice. The main objective of our research is to show that the method engineering concepts which have been developed in the last few decades but never really penetrated to practice are applicable in real settings and that could contribute to software industry.

Abstract:
Virtual Reality Simulators create a multisensory 3D space for subjects by using visual screens and auditory displays. In this multimedia presence, audio plays a significant role. Users often wear headphones and a virtual sound space is rendered with directional information.
In order to achieve this, psychoacoustic measurements, implementation of digital filters, subjective listening tests etc. are required. The whole process raises several problems, so information technology and engineering solutions may help reducing errors, inconvenience or even price.
Besides basic research questions about the human spatial hearing, measurement and playback systems support the development of assistive applications, devices mostly focused on people with disabilities, such as rehabilitation, sports or the community of the visually impaired.

Abstract: Safety and comfort of passenger cars are improving steadily. This leads to a reduced number of fatal traffic accidents while the number of driven kilometers per year increases. Several factors are responsible for this development. Among them the application of automatic control plays an important role. Modern automotive control systems can support the driver in critical situations, e.g. by appropriate brake interventions and/or improve the handling and efficiency of cars, e.g. by active steering or intelligent throttle control. In this talk the principles of selected automotive control systems will be discussed. It will be outlined how model-based design techniques can be employed to develop powerful assistance systems for modern passenger cars.

Abstract:
There are many challenging problems in computer vision for which state-of-the-art solutions fall short of performing perfectly. The realization that many of these tasks are arduous for computers yet are relatively easy for humans has inspired many researchers to approach those problems from a human computation viewpoint, using methods that include crowdsourcing and games – often called ‘games with a purpose’ (GWAPs). The talk discusses how we can use human computation (in general) and particularly games to help uncover hidden aspects of visual perception and use these findings to improve computer vision solutions to related problems. It particularly highlights two examples of our recent work on the topic:
1.   Guess That Face (with Mathias Lux and Justyn Snyder, CHI 2013): a face recognition game that reverse engineers the human biological threshold for accurately recognizing blurred faces of celebrities under time-varying conditions.
2.   Ask’N’Seek (with Vincent Charvillat and Axel Carlier, ECCV 2012): an object detection and labeling game that asks users to guess the location of a hidden region within an image with the help of semantic and topological clues and uses the information collected from game logs, combined with results from content analysis algorithms, to feed a machine learning algorithm that outputs the outline of the most relevant regions within the image and their names.

Abstract: Many daily activities we want to finish as fast and smoothly as possible. The same applies when we use our computing devices. Examples range from low-level actions, such as selecting the “Print” item from the “File” menu or clicking on desktop icons, to higher level activities and more complex tasks, such as finding the favorite holiday photo in the personal collection, or to use a smartphone to navigate a city map or to browse a long list of products before deciding on a purchase. Throughout the years, the desire for interaction efficiency has motivated the Human-Computer Interaction research community to seek and explore new interaction mechanisms and user interface techniques that improve on the state of the art. In this talk I will present a handful of past projects in which we have applied the experimental method to arrive at insights regarding novel user interface design solutions.
