- KonferenzbeitragHow to Determine the Effectiveness and Efficiency of Coordination and Awareness Support Systems.(Mensch und Computer 2017 - Workshopband, 2017) Oemig, Christoph; Gross, TomCoordination and awareness have been research issues for many years. Effortless coordination and effective awareness support have been goals ever since. Yet, measuring the effectiveness and efficiency of these support systems has remained a complex issue leaving researches with the dilemma that achieving either goal requires some kind of measurement. In this paper we introduce our approach that has the goal to determine whether a certain coordination or awareness support system actually improves a user group’s coordination. We demonstrate how a simple interactive task helps to achieve this goal.
- Workshopbeitrag“I know who, but not how many!” – Forgetting in Collaborative Settings(Mensch und Computer 2016 - Tagungsband, 2016) Oemig, Christoph; Gross, TomForgetting is a natural mechanism that keeps our memory from overloading. In the past it had a large influence on the design of Human-Computer Interaction. Yet, its main focus was on single user tasks and systems. Collaborative settings introduce the secondary task of coordination which has to share the already scarce capacity of the working memory with the knowledge of the primary task. Secondary task knowledge is critical to a team’s success but stored subconsciously, i.e., it can be easily lost due to interruption or interference. Therefore, a solid understanding of forgetting in collaborative settings is expected to have strong implications on the design of collaborative systems. This paper presents our first steps towards the goal applying an exploratory experiment observing primary and secondary task knowledge in a shared task. The results show how secondary task knowledge finds its way to stay alive.
- WorkshopbeitragIllusive, Ineffective, Inefficient, Ideal: Standardized Coordination Task Assessments of Awareness Support(Mensch & Computer 2011: überMEDIEN|ÜBERmorgen, 2011) Oemig, Christoph; Gross, TomAwareness support in cooperative systems provides users with mutual information on each others’ presence and activities. Measuring its effectiveness is a complex task since people tend to forget quickly. Therefore, it becomes imperative to use a technique generating results while a user’s awareness is still present. The Standardized Coordination Task Assessment measures response times and error rates visualizing the results in a four quadrant system distinguishing illusive, ineffective, inefficient, and ideal systems. This helps awareness support researchers and designers to drive their effort into the right direction already at early development stages.
- KonferenzbeitragImpacts of Disruption on Secondary Task Knowledge: Recovery Modes and Social Nuances(Mensch und Computer 2019 - Tagungsband, 2019) Oemig, Christoph; Gross, TomThe working memory of the human brain has always had a strong influence on the design of Human-Computer Interaction. Yet, it is limited in capacity and loses its contents over time. Research regarding these constraints typically focused on single user tasks and systems. Collaborative settings and systems introduce the need for the secondary task of coordination which shares the same conditions and constraints as the knowledge of the primary task. Additionally, it is easily compromised by interruption and interference. Our approach seeks to understand the impacts of disruption on secondary task knowledge, but from a different angle than previous related work. Since it is hard to avoid disruption entirely, it aims to understand how users recover from disruptions in order to help them recover the best way possible from different types of interruptions using appropriate mechanisms and cues. This paper reports on the results of one of the first experiments along the way, observing the effects of four types of interruptions revealing different modes of recovery and social nuances that inform the design of adaptive coordination support systems.

- KonferenzbeitragPRIMInality: Towards Human-Centred Instant Messaging Infrastructures(Mensch und Computer 2005: Kunst und Wissenschaft - Grenzüberschreitung der interaktiven Art, 2005) Gross, Tom; Oemig, ChristophInstant messaging systems facilitate the coordination of geographically distributed users through support for presence and availability information, and ad-hoc conversations among online users. However, despite their widespread use they seem to be designed and developed from a technology-push, rather than a user-centred design perspective. In fact, concerning the subtleties of human behaviour and human perception of others there is a broad gap between the body of knowledge in sociology, and the functionality of these systems. In this paper we present concepts for the support of advanced and nuanced online states; for the automatic and precise inference of the online states based on data from software sensors and hardware sensors; and the adaptation of the system behaviour to the inferred online state. Furthermore, we describe the implementation of these concepts on top of two open platforms for the rapid and easy development of sensor-based, and instant messaging infrastructures.
- KonferenzbeitragShifts in Significance: How Group Dynamics Improves Group Awareness(Mensch und Computer 2007: Interaktion im Plural, 2007) Oemig, Christoph; Gross, TomAppropriate awareness support has been an issue in the area of Computer-Supported Cooperative Work (CSCW) for quite a while. Yet, many challenges like the dual trade-off between awareness and privacy and awareness and disruption still remain. In this paper we present our human-centred approach on how to utilise group dynamics and team development specific information patterns to control awareness information in ubiquitous sensor-based environments. The consolidated results from our concept, study and prototype demonstrate how an information item’s shift in significance can contribute improvements to the user’s overall awareness experience.
- KonferenzbeitragThe Awareness-/Coordination-Support-System Paradox(Mensch & Computer 2014 - Tagungsband, 2014) Oemig, Christoph; Gross, TomCoordination and awareness have been topics in the area of Computer-Supported Cooperative Work (CSCW) starting from day one. Effortless coordination has been a major goal ever since. However, while awareness research became quite popular, coordination got increasingly out of focus. Its concepts stayed rather theoretical lacking concrete steps towards the original goal due to the absence of appropriate measurement techniques and tools. There is even an on-going general dispute if discount usability techniques deliver valid results as compared to real-world field studies. This paper supports their validity and demonstrates how the Standardized Coordination Task Assessment (SCTA) technique is used to extend the mechanics of collaboration, a framework for discount usability evaluations, allowing awareness and coordination effort assessments. The results appeared not only to be reasonable but the experiment revealed an effect we named the awareness-/coordination-support system paradox.
- KonferenzbeitragUX Designer By Default(Softwaretechnik-Trends Band 43, Heft 1, 2023) Oemig, ChristophDie Business Analyse (BA) bzw. das Requirements Engineering (RE) und die User Experience (UX) haben eine engere Beziehung als man zunächst annehmen würde. Insbesondere wenn kein dediziertes UX Personal verfügbar ist, kann dies schnell zu suboptimalen Projektergebnissen führen, da es keine Option ist, keine UX zu erzeugen. Dieser Beitrag erläutert kurz und knapp die Zusammenhänge und die Rolle des BA/RE als Teil davon. Darüber hinaus werden Vorschläge gemacht, wie durch ein leicht angepasstes Vorgehen in der Anforderungsanalyse Verbesserungen der UX erreicht werden können.
