Abstract

Gamifying rehabilitation is an efficient way to improve motivation and exercise frequency. However, between flow theory, self-determination theory or Bartle’s player types there is much room for speculation regarding the mechanics required for successful gamification, which in turn leads to increased motivation. For our study, we selected a gamified solution for motion training (an exergame) where the playful design elements are extremely simple.

The contribution is three-fold: we show best practices from the state of the art, present a study analyzing the effects of simple gamification mechanics on a quantitative and on a qualitative level and discuss strategies for playful design in therapeutic movement games.

Abstract

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.

Abstract

We present the design outline of a context-aware interactive system for smart learning in the STEM curriculum (science, technology, engineering, and mathematics). It is based on a gameful design approach and enables “playful coached learning” (PCL): a learning process enriched by gamification but also close to the learner’s activities and emotional setting.

After a brief introduction on related work, we describe the technological setup, the integration of projected visual feedback and the use of object and motion recognition to interpret the learner’s actions. We explain how this combination enables rapid feedback and why this is particularly important for correct habit formation in practical skills training. In a second step, we discuss gamification methods and analyze which are best suited for the PCL system. Finally, emotion recognition, a major element of the final PCL design not yet implemented, is briefly outlined.

Educational Playgrounds: How Context-aware Systems Enable Playful Coached Learning

Educational Playgrounds: How Context-aware Systems Enable Playful Coached Learning

In: Interactions, 24(1), 54–57, 2016
DOI = 10.1145/3012951

Abstract

In this article, we present the vision of a context-aware system that supports educators and offers students what we call playful coached learning (PCL).

Insights

  • A system that is aware of real-world interactions strongly contributes to the user’s sense of interaction and exchange.
  • Adding gamification is not enough. PCL should also consider a student’s emotions.
  • Learning with a context-aware system can be a relief for students and educators, increasing their autonomy.
  • PCL is a good example of a combinatory innovation.

Delphi Study on Emotion Recognition within Workshop @ AAL-Forum 2016

AAL Forum 2016 KeynoteThe AAL Forum 2016 takes place in St. Gallen from September 26 to 29. Gerald Bieber from Fraunhofer IGD and Oliver Korn are chairing Workshop 28: From Recognizing Motion to Emotion Awareness – Perspectives for Future AAL Solutions:

There are several examples for the successful use of sensor-based motion recognition, e.g. for fall prevention or rehabilitation of elderly persons. However, motivation is always key when it comes to redundant exercises. While motion recognition helps to ensure a movement is performed correctly, emotion recognition can help to ensure an exercise is performed regularly.

The contribution of the workshop is three-fold. We will investigate best practices using motion recognition, show some potentials of emotion recognition and finally will develop perspectives for the application of emotion recognition in existing and future AAL solutions. The last section will be integrated in a Delphi study.

PhD thesis: Context-Aware Assistive Systems for Augmented Work. A Framework Using Gamification and Projection

At May 21st I finished my PhD in Computer Science at the Institute for Visualization and Interactive Systems (VIS) at the University of Stuttgart. The advisors were Prof. Dr. Albrecht Schmidt from the VIS and Prof. Dr. Fillia Makedon from the Universiy of Texas Alington (UTA). The work is based on the project ASLM acquired by Prof. Dr. Thomas Hörz from the University of Applied Sciences Esslingen and was continued in the project motionEAP.

An Augmented Workplace for Enabling User-Defined Tangibles

An Augmented Workplace for Enabling User-Defined Tangibles

In: Extended Abstracts of the ACM SIGCHI Conference on Human Factors in Computing Systems, ACM, New York, NY, USA, 2014, DOI =10.1145/2559206.2581142

Abstract

In this work, we introduce a novel setup for an augmented workplace, which allows for de ning and interacting with user-de ned tangibles. State-of-the-art tangible user interface systems equip both the underlying surface and the tangible control with sensors or markers. At the workplace, having unique tangibles for each available action results in confusion. Furthermore, tangible controls mix with regular objects and induce a messy desk. Therefore, we introduce the concept of user-de fined tangibles, which enable a spontaneous binding between physical objects and digital functions. With user-de fined tangibles, the need for specially designed tangible controls disappears and each physical object on the augmented
workplace can be turned into a tangible control. We introduce our prototypical system and outline our proposed interaction concept.

Tangible and Intuitive Interaction – Video of a Prototype

motionEAP-prototypeAt the University of Stuttgart Institute for Visualization and Interactive Systems (VIS) and the Korion GmbH I am part of a team developing the prototype of a new kind of assistive system in the project motionEAP. The prototype combines the 3D-spaces of the depth sensors Kinect and Leap Motion.

It detects individual fingers of both hands and allows to direct processes with simple gestures. Both gestures in space and touch events on the surface of the workspace are detected. At the same time the system allows to project videos or interactive 3D-spaces on any kind of surface.

As an example this allows to zoom or rotate a workpart through simple gestures. In future development iterations we will integrate object detection allowing a context- or product-specific feedback on processes, e.g. in manual assembly. This context-aware feedback is a pre-requisite for the later implementation of gamification components. These will allow to integrate feedback smoothly and least disruptive while motivating the assistive system’s users.

The following video illustrates the prototype’s current features:

Abstract

This chapter introduces the prototype of a software developed to assist elderly persons in performing physical exercises to prevent falls. The result — a combination of sport exercises and gaming — is also called “exergame.” The software is based on research and development conducted within the
“motivotion60+” research project as part of the AAL-program (Ambient Assisted Living).

The authors outline the use of motion recognition and analysis to promote physical activity among elderly people: it allows Natural Interaction (NI) and takes away the conventional controller, which represented a hurdle for the acceptance of technical solutions in the target group; it allows the real-time scaling of the exergame’s difficulty to adjust to the user’s individual fitness level and thus keep motivation up. The authors’ experiences with the design of the exergame and the first results from its evaluation regarding space, interaction, design, effort, and fun, as well as human factors, are portrayed. The authors also give an outlook on what future exergames using motion recognition should look like.
