This book develops valuable new approaches to digital out-of-home media and digital signage in urban environments. It offers solutions for communicating interactive features of digital signage to passers-by. Digital out-of-home media and digital signage screens are becoming increasingly interactive thanks to touch input technology and gesture recognition. To optimize their conversion rate, interactive public displays must 1) attract attention, 2) communicate to passers-by that they are interactive, 3) explain the interaction, and 4) provide a motivation for passers-by to interact. This book highlights solutions to problems 2 and 3 above. The focus is on whole-body interaction, where the positions and orientations of users and their individual body parts are captured by specialized sensors (e.g., depth cameras). The book presents revealing findings from a field study on communicating interactivity, a laboratory on analysing visual attention, a field study on mid-air gestures, and a field study on using mid-air gestures to select items on interactive public displays.

Zu Anfang unseres Jahrhunderts begründete der Wiener Staatsrechtslehrer Hans Kelsen (1881 bis 1973) seine – später als »Reine Rechtslehre« oder »Wiener Schule der Rechtstheorie« bezeichnete – Theorie des positiven Rechts.Der Verfasser legt dar, wie der Begriff des »positiven Rechts« im Rahmen der Theorie Kelsens bestimmt wird und welche Gründe für die Wahl dieses Gegenstandes sprechen. Einleitend wird auch der wissenschaftsgeschichtliche, philosophische und historische Hintergrund von Kelsens Rechtslehre beleuchtet. Zum Inhalt der Theorie wird das Wesentliche über die Normenlehre (Begriff und Arten der Normen) ausgeführt und der stufenförmige Aufbau der Rechtsordnung skizziert (Lehre von Stufenbau der Rechtsordnung). Im Anschluß daran wird die Interpretationslehre der erörterten Theorie behandelt. Schließlich wird dargelegt, aus welchen Gründen die Reine Rechtslehre das Verhältnis von Recht und Staat als solches der Identität sieht. Betrachtungen über die Rolle der Logik in der Rechtswissenschaft beschließen die Überlegungen.Der Autor ist Ordinarius für Staats- und Verwaltungsrecht in Wien und Geschäftsführer des Hans Kelsen-Instituts.
