To what extent do digital designers and user researchers in industry make use of AI-powered systems to support their work? The answer seems to be “not much,” as we found in a survey with 34 practitioners. In general, there seems to be little awareness of the specific advantages AI can bring to a design process and which tools are already out there, despite significant issues with existing processes that could be well mitigated with the help of AI. However, designers and researchers are very open to the topic and would appreciate AI-powered systems to support them in both ideation and evaluation. Providing practitioners with such systems that are easily accessible and demonstrate added value holds great opportunities.
Prototyping in 3D isn't the same as in just two dimensions. Compared to regular, flat websites, augmented and virtual reality have very different requirements when it comes to creating prototypes. To close a gap in the medium-fidelity range of AR/VR prototyping methods, we've created 360theater, which makes use of dioramas and 360° content for creating physical-digital prototypes. We've used our new method in workshops with design students and found that it comes close to the final experience while complementing other methods with different levels of fidelity.
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. 🎉
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
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
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
Our paper "S.O.S.: Does Your Search Engine Results Page (SERP) Need Help?"—co-authors are Dr. Andreas Both (Unister) and Prof. Martin Gaedke (TU Chemnitz)—has been awarded a Best Paper Honarable Mention Award by ACM SIGCHI, the Special Interest Group on Computer–Human Interaction of the Association for Computing Machinery. According to Wikipedia, ACM SIGCHI is "the world's leading organization in… Continue reading S.O.S. Receives Best Paper Honarable Mention Award at CHI ’15
Phew! It was a rather busy (that's why I haven't been posting in a while), but also very successful start into the new year. A total of three full papers have been accepted at various conferences and journals. So basically, I've been revising and resubmitting papers since Christmas. First, our paper about Inuit has been… Continue reading #papershizzle
(Disclaimer: motherfuckingwebsite.com was not made by me!) The post in which I review motherfuckingwebsite.com and propose some changes to make it even more perfect (see here) is the most widely read post on my blog by far. To date, it has received 8,715 views, with the front page of my blog being in second place having… Continue reading ICYMI: This is a motherfucking website and I wrote a motherfucking conference article about it
The continuous evaluation of an e-commerce company's web applications is crucial for ensuring customer satisfaction and loyalty. Such evaluations are usually performed as split tests, i.e., the comparison of two slightly different versions of the same webpage with respect to a target metric. Usually, metrics that stakeholders are interested in include completed checkout processes, submitted… Continue reading Usability-based Split Testing or How to infer web interface usability from user interactions
