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.

In many scientific studies lens experiments are part of the curriculum. The conducted experiments are meant to give the students a basic understanding for the laws of optics and its applications. Most of the experiments need special hardware like e.g. an optical bench, light sources, apertures and different lens types. Therefore it is not possible for the students to conduct any of the experiments outside of the university’s laboratory. Simple optical software simulators enabling the students to virtually perform lens experiments already exist, but are mostly desktop or web browser based. Augmented Reality (AR) is a special case of mediated and mixed reality concepts, where computers are used to add, subtract or modify one’s perception of reality. As a result of the success and widespread availability of handheld mobile devices, like e.g. tablet computers and smartphones, mobile augmented reality applications are easy to use. Augmented reality can be easily used to visualize a simulated optical bench. The students can interactively modify properties like e.g. lens type, lens curvature, lens diameter, lens refractive index and the positions of the instruments in space. Light rays can be visualized and promote an additional understanding of the laws of optics. An AR application like this is ideally suited to prepare the actual laboratory sessions and/or recap the teaching content. The authors will present their experience with handheld augmented reality applications and their possibilities for light and optic experiments without the needs for specialized optical hardware.

For an ultra-efficient car-engineering project, we aim to utilize AR technology for the driver and engineering team. A real-time monitoring of the car’s operational parameters is crucial for best possible fuel efficiency and overall performance.

In the age data digitalization, important applications of optics and photonics based sensors and technology lie in the field of biometrics and image processing. Protecting user data in a safe and secure way is an essential task in this area. However, traditional cryptographic protocols rely heavily on computer aided computation. Secure protocols which rely only on human interactions are usually simpler to understand. In many scenarios development of such protocols are also important for ease of implementation and deployment. Visual cryptography (VC) is an encryption technique on images (or text) in which decryption is done by human visual system. In this technique, an image is encrypted into number of pieces (known as shares). When the printed shares are physically superimposed together, the image can be decrypted with human vision. Modern digital watermarking technologies can be combined with VC for image copyright protection where the shares can be watermarks (small identification) embedded in the image. Similarly, VC can be used for improving security of biometric authentication. This paper presents about design and implementation of a practical laboratory experiment based on the concept of VC for a course in media engineering. Specifically, our contribution deals with integration of VC in different schemes for applications like digital watermarking and biometric authentication in the field of optics and photonics. We describe theoretical concepts and propose our infrastructure for the experiment. Finally, we will evaluate the learning outcome of the experiment, performed by the students. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
