The Effect of Gamification on Emotions - The Potential of Facial Recognition in Work Environmentsns
(2015)
Gamification means using video game elements to improve user experience and user engagement in non-game services and applications. This article describes the effects when gamification is used in work contexts. Here we focus on industrial production. We describe how facial recognition can be employed to measure and quantify the effect of gamification on the users’ emotions.
The quantitative results show that gamification significantly reduces both task completion time and error rate. However, the results concerning the effect on emotions are surprising. Without gamification there are not only more unhappy expressions (as to expect) but surprisingly also more happy expressions. Both findings are statistically highly significant.
We think that in redundant production work there are generally more (negative) emotions involved. When there is no gamification happy and unhappy balance each other. In contrast gamification seems to shift the spectrum of moods towards “relaxed”. Especially for work environments such a calm attitude is a desirable effect on the users. Thus our findings support the use of gamification.
Social robots are robots interacting with humans not only in collaborative settings, but also in personal settings like domestic services and healthcare. Some social robots simulate feelings (companions) while others just help lifting (assistants). However, they often incite both fascination and fear: what abilities should social robots have and what should remain exclusive to humans? We provide a historical background on the development of robots and related machines (1), discuss examples of social robots (2) and present an expert study on their desired future abilities and applications (3) conducted within the Forum of the European Active and Assisted Living Programme (AAL). The findings indicate that most technologies required for the social robots' emotion sensing are considered ready. For care robots, the experts approve health-related tasks like drawing blood while they prefer humans to do nursing tasks like washing. On a larger societal scale, the acceptance of social robots increases highly significantly with familiarity, making health robots and even military drones more acceptable than sex robots or child companion robots for childless couples. Accordingly, the acceptance of social robots seems to decrease with the level of face-to-face emotions involved.
Innovative technologies and concepts will emerge as we move towards a more dynamic, service-based, market-driven infrastructure, where energy efficiency and savings can be facilitated by interactive distribution networks. A new generation of fully interactive Information and Communication Technologies (ICT) infrastructure has to be developed to support the optimal exploitation of the changing, complex business processes and to enable the efficient functioning of the deregulated energy market for the benefit of citizens and businesses. The architecture of such distributed system landscapes must be designed and validated, standards need to be created and widely supported, and comprehensive, reliable IT applications will need to be implemented. The collaboration between a smart house and a smart grid is a promising approach which, with the help of ICT can fully unleash the capabilities of the smart electricity network.
Ein neuer Ansatz wurde für mobile Roboter zur gleichzeitigen 3D (Drei-Dimensionaler) Kartierung und Lokalisierung vorgestellt. Die Grundlage bilden attributierte Flächenmodelle, die z.B. von segmentierten Laserscanner-Tiefenbildern stammen. Zur Optimierung der Gesamtähnlichkeit zwischen Flächenmodellen unter Zeitbedingungen werden mehrere Verfahren (Beschränkte Baumsuche, Iterative Verfeinerung, Evolutionäralgorithmus) kombiniert. Es wird speziell anhand der Ähnlichkeitsmaße gezeigt, wie das Wissen über die Lage stufenweise generiert und verwendet wird. Erste Messungen an realen segmentierten Tiefenbildfolgen zeigen, dass das Verfahren unbekannte übelappung, Verdeckung und Segmentierungsfehler toleriert sowie Echtzeitpotenzial besitzt.
Analysis of Amplitude and Phase Errors in Digital-Beamforming Radars for Automotive Applications
(2020)
Fundamentally, automotive radar sensors with Digital-Beamforming (DBF) use several transmitter and receiver antennas to measure the direction of the target. However, hardware imperfections, tolerances in the feeding lines of the antennas, coupling effects as well as temperature changes and ageing will cause amplitude and phase errors. These errors can lead to misinterpretation of the data and result in hazardous actions of the autonomous system. First, the impact of amplitude and phase errors on angular estimation is discussed and analyzed by simulations. The results are compared with the measured errors of a real radar sensor. Further, a calibration method is implemented and evaluated by measurements.
This paper describes a taxonomy which allows to assess and compare different implementations of master data objects. A systematic breakdown of core entities provides a framework to tell apart four subdividing categories of master data objects: independent and dependent objects, relational objects, and reference objects that serve to attribute information. This supports the preparation of data migrations from one system to another.
Im Frühjahr 1995 entstand die Idee, einen Lottozahlengenerator als Demonstrations- und Studienobjekt, für die Anwendung komplexer digitaler Entwurfsmethoden, zu entwerfen. Mit Hilfe der Schaltung ist es möglich, 6 verschiedene Zahlen zufällig aus 49 Zahlen zu ermitteln. Bei der Ziehung der einzelnen Zahlen werden verschiedene Töne und Melodien erzeugt. Die Schaltung ist so konzipiert, daß eine einfache Bedienung möglich ist. Der Chip wurde als Standardzellen-Entwurf mit einer Fläche von ca. 7 um² geroutet.
Nach dem Nachweis der Funktionalität des an der Fachhochschule Offenburg entwickelten Mikroprozessorkernels FHOP (First Homemade Operational Processor), wird eine Anwendung des Kernels in einem Applikationschip beschrieben.
Der Thermologger-ASIC soll mit Hilfe eines Temperatursensors die Umgebungstemperatur bei technischen Prozessen in regelmäßigen Zeitabständen erfassen und abspeichern. Die Meßwerte werden bei Bedarf ber eine serielle Schnittstelle des Thermologger-ASICs an einen PC übertragen und ausgewertet. Zur Verringerung der Leistungsaufnahme wird zwischen zwei Temperaturmessungen in einen Power-Down-Mode geschaltet.
Der ASIC soll später in einer Chipkarte integriert werden.
