This paper describes a comparative study of two tactile systems supporting navigation for persons with little or no visual and auditory perception. The efficacy of a tactile head-mounted device (HMD) was compared to that of a wearable device, a tactile belt. A study with twenty participants showed that the participants took significantly less time to complete a course when navigating with the HMD, as compared to the belt.
Bank and trust – two words but one meaning in customers’ minds. When interacting with financial service providers, customers are consistently looking for “trust signals” that comfort their decisions and “distrust signals” which create doubt. Therefore, service providers need a deep understanding of the customers’ requirements and wishes. To identify trust and distrust signals, we combine established user experience research methods with a new testing procedure to gain helpful recommendations for optimizing the online appearance of banks. The contribution is divided into three parts: Firstly, we investigate current approaches in the financial service industry. Secondly, we provide a corpus describing the relationship between the customers’ perception of a bank’s website and trust. Thirdly, an empirical study based on qualitative user experience testing with banking website customers shows the value gained by optimizing the banks’ virtual interface by enhancing “trust signals” and avoiding “distrust signals”.
Top-level staff prefers to live in urban areas with perfect social infrastructure. This is a common problem for excellent companies (“hidden champions”) in rural areas: even if they can provide the services qualified applicants appreciate for daily living, they fail to attract them because important facts are not presented sufficiently in social media or on the corporate website. This is especially true for applicants with families. The contribution of this paper is four-fold: we provide an overview of the current state of online recruiting activities of hidden champions (1). Based on this corpus, we describe the applicant service gap for company information in rural communes (2). A study on user experience (UX) identifies the applicants’ wishes and needs, focusing on a family-oriented information system on living conditions in rural areas (3). Finally, we present the results of an online survey on the value of such information systems with more than 200 participants (4).
Interaction and capturing information from the surrounding is dominated by vision and hearing. Haptics on the other side, widens the bandwidth and could also replace senses (sense switching) for impaired. Haptic technologies are often limited to point-wise actuation. Here, we show that actuation in two-dimensional matrices instead creates a richer input. We describe the construction of a full-body garment for haptic communication with a distributed actuating network. The garment is divided into attachable-detachable panels or add-ons that each can carry a two dimensional matrix of actuating haptic elements. Each panel adds to an enhanced sensoric capability of the human- garment system so that together a 720° system is formed. The spatial separation of the panels on different body locations supports semantic and theme-wise separation of conversations conveyed by haptics. It also achieves directional faithfulness, which is maintaining any directional information about a distal stimulus in the haptic input.
Socially assistive robots (SARs) are becoming more prevalent in everyday life, emphasizing the need to make them socially acceptable and aligned with users' expectations. Robots' appearance impacts users' behaviors and attitudes towards them. Therefore, product designers choose visual qualities to give the robot a character and to imply its functionality and personality. In this work, we sought to investigate the effect of cultural differences on Israeli and German designers' perceptions of SARs' roles and appearance in four different contexts: a service robot for an assisted living/retirement residence facility, a medical assistant robot for a hospital environment, a COVID-19 officer robot, and a personal assistant robot for domestic use. The key insight is that although Israeli and German designers share similar perceptions of visual qualities for most of the robotics roles, we found differences in the perception of the COVID-19 officer robot's role and, by that, its most suitable visual design. This work indicates that context and culture play a role in users' perceptions and expectations; therefore, they should be taken into account when designing new SARs for diverse contexts.

This work documents the rising acceptance of social robots for healthcare as well as their growing economic potential from 2017 to 2021. The comparison is based on two studies in the active assisted living (AAL) community. We first provide a brief overview of social robotics and a discussion of the economic potential of social health robots. We found that, despite the huge potential for robotic support in healthcare and domestic routines, social robots still lack the functionality to access that potential. At the same time, the study exemplifies a rise in acceptance: all health-related activities are more accepted in 2021 when in 2017, most of them with high statistical significance. When investigating the economic perspective, we found that persons are aware of the influence of cultural, spiritual, or religious beliefs. Most experts (57%), having a European background, expect the state or the government to be the key driver for establishing social robots in health and significantly prefer leasing or renting a social health robot to buying one. Nevertheless, we speculate that it might be a global financial elite which is first to adopt social robots.
Rehabilitationsmaßnahmen nach Unfällen oder Krankheiten sind oft langwierig und häufig mit Schmerzen sowie Frustration verbunden – und Ähnliches gilt für Präventionstraining. Die spielerische Anreicherung des Trainings (im Folgenden: Gamification) kann dieser Entwicklung durch die Steigerung des Spaßfaktors entgegenwirken. Im Gegensatz zu regulären Spielen kann es durch die höhere Motivation und Immersion im Training allerdings zu einer verminderten Schmerzwahrnehmung und damit einer Verschlechterung des Gesundheitszustands bis hin zu einer erneuten Verletzung kommen. Daher war es bislang erforderlich, solche Ansätze kontinuierlich therapeutisch zu begleiten. Für eine autonome Intervention, zur Entlastung von Therapeuten, aber auch im Heimbereich ist eine automatisierte Anpassung des Schwierigkeitsgrads des Bewegungstrainings und eine individualisierte Zielsetzung und -kontrolle von zentraler Bedeutung. Diese Herausforderung ist in bestehenden Ansätzen zu wenig adressiert bzw. beschrieben worden. Der Einsatz künstlicher Intelligenz kann hier einen entscheidenden Beitrag zu leisten – insbesondere hybride Ansätze, die expertenbasierte Entscheidungsbäume mit Verfahren des maschinellen Lernens kombinieren, könnten in der Zukunft einen wichtigen Beitrag zu einer erfolgreichen Rehabilitation und Prävention liefern.
Gamification, die spielerische Anreicherung von Tätigkeiten, erfreut sich zunehmender Beliebtheit. Insbesondere in den Bereichen Gesundheit (Exergames) oder Lernen (Serious Games, Edutainment) gibt es eine Vielzahl erfolgreicher Anwendungen. Weniger verbreitet ist Gamification dagegen bislang bei Arbeitsprozessen. Zwar gibt es erfolgreiche Ansätze im Bereich Dienstleistung und Service (z. B. bei Callcentern), der Bereich der industriellen Produktion wurde jedoch bis vor wenigen Jahren nicht adressiert.
Dieses Kapitel gibt einen Überblick der Entwicklung von Gamification und zeigt den Stand der Technik. Wir leiten allgemeine Anforderungen für Gamification im Produktionsumfeld ab und stellen zwei neue Ansätze aus der aktuellen Forschung vor. Diese werden in einer Studie mit Trainern aus der Automobilbranche auf Akzeptanz untersucht. Die Ergebnisse zeigen eine insgesamt positive Haltung zur Gamifizierung der Produktion und eine sehr hohe Akzeptanz insbesondere des Pyramiden-Designs.
The number of impaired persons rises -- as a result of both regular degradation with age and psychological problems like burnout. Sheltered work organizations aim to reintegrate impaired persons into work environments and prepare them for the re-entry in the regular job market.
Both for elderly and for impaired persons it is crucial to quickly assess the abilities, to identify limits and potentials and thus find work processes suitable for their skill profile.
This work focuses on the analysis and comparison of software-tools that assess the abilities of persons with impairments. We describe two established generic tools (CANTAB, Cogstate), analyze a yet unknown specialized tool (Hamet) and present a new gamified tool (GATRAS).
Finally, we present a study with 20 participants with impairments, comparing the tools against a ground truth baseline generated by a real-world assembly task.
