Two research papers I co-authored have been recently accepted to prestigious international conferences: ACM CHI and ICWE. The first one even won a Best Paper Award. 🎉
There is not a single, "best" definition of mixed reality. Instead, there are six widely used and partly competing notions that can be classified based on a 7-D conceptual framework of mixed reality.
Abstract: In the first year, a clear majority of the investigated companies secured more than $0.395m of seed or angel funding; in the second year, a clear majority secured more than $4.366m of Series A or venture funding; and in the third year, a clear majority secured more than $11.131m of Series B funding. At… Continue reading What Do Highly Successful Start-ups Have in Common?
From 2013 till 2016 I've done an industrial Ph.D. at Unister GmbH in Leipzig in cooperation with Chemnitz University of Technology. This means that I worked in Unister's R&D department, which at that time developed a novel semantic search engine, and wrote my thesis about the part I contributed to the project. A few days… Continue reading Pros & Cons of an Industrial Ph.D. Program
When looking at current research, there is plenty of existing work inquiring into how users use search engines1 and how future search interfaces could look like2. Yet, an investigation of users' perceptions of and expectations towards current and future search interfaces is still missing. Therefore, at this year's International Conference on WWW/Internet (ICWI '16) my co-author Martin Gaedke… Continue reading REFOCUS: Current & Future Search Interface Requirements for German-speaking Users
According to Patnaik (2009), Design Thinking is "any process that applies the methods of industrial designers to problems beyond how a product should look." The term was already used as early as 1987 by Rowe in his eponymous book in an architectural context and has lately become popular through research done at Stanford University and the Hasso Plattner… Continue reading On Design Thinking
Usability testing is often perceived as cumbersome and time-consuming and therefore not thoroughly applied. This was one of the key observations leading to the topic of my PhD thesis. Particularly conducting tests with actual users is often omitted, which results in the release of suboptimal products and websites. In my thesis, I tackle this problem through more… Continue reading The U Score: Redesigning Usability Testing
At this year's INFORMATIK conference held by the GI in Cottbus, I had the chance to present a research paper (full text here) about HoloBuilder—officially titled "Enabling Industry 4.0 with holobuilder"1—that I wrote together with my colleagues Kristina Tenhaft, Simon Heinen and Harry Handorf. In our paper, we examine HoloBuilder from a research rather than… Continue reading Enabling Industry 4.0 with HoloBuilder
My PhD thesis introduces a novel methodology that is named Search Interaction Optimization (SIO) and is used for designing, evaluating and optimizing search engine results pages (so-called SERPs). As a proof-of-concept of this new methodology, I've developed a corresponding SIO toolkit, which comprises a total of seven components1 (most of which have already been introduced in previous… Continue reading The Search Interaction Optimization Toolkit – The Essence of my PhD Thesis
As one of the building blocks of my PhD thesis, I have developed a novel instrument for measuring the usability of web interfaces, which is simply called Inuit—the Interface Usability Instrument1. This was necessary because a usability instrument that is suited for the automatic methods for Search Interaction Optimization I have developed in my PhD… Continue reading INUIT: The Interface Usability Instrument
