Software ergonomics for multimedia user interfaces - Part 2: Multimedia navigation and control (ISO 14915-2:2003)

ISO 14915-2:2003 provides recommendations and requirements for the design of multimedia user interfaces with respect to the following aspects: design of the organization of the content, navigation and media-control issues. ISO 14915-2:2003 is limited to the design of the organization of the content and does not deal with the design of the content in general. Design issues within a single medium (e.g. the lighting of a film sequence) are only addressed with respect to the ergonomic issues related to user controls.

Software-Ergonomie für Multimedia-Benutzerschnittstellen - Teil 2: Multimedia-Navigation und Steuerung (ISO 14915-2:2003)

Dieser Teil der ISO 14915 enthält Empfehlungen für und Anforderungen an die Gestaltung von Multimedia- Benutzerschnittstellen im Hinblick auf die folgenden Aspekte: Gestaltung des Aufbaus des Inhalts, Navigation und Fragen der Mediensteuerung. Dieser Teil der ISO 14915 beschränkt sich auf die Gestaltung des Inhaltsaufbaus und behandelt nicht die Gestaltung des Inhalts im Allgemeinen. Fragen der Gestaltung in einem einzelnen Medium (z. B. die Beleuchtung in einer Filmsequenz) werden nur in Bezug auf die mit der Benutzersteuerung in Zusammenhang stehenden Fragen angesprochen.
ISO 14915-2
¾ schafft Rahmenbedingungen für den Aufbau von Multimedia-Anwendungen;
¾ gibt Informationen und Empfehlungen zur Gestaltung von Navigationsstrukturen und Navigations-mechanismen für die Nutzung in Multimedia-Anwendungen;
¾ enthält Informationen und Empfehlungen zur Gestaltung von Steuerungselementen für die Nutzung in Multimedia-Anwendungen.
In diesem Teil der ISO 14915 werden Unterhaltungsanwendungen nicht ausdrücklich angesprochen, obgleich einige Empfehlungen auch für diesen Bereich zutreffen können. Fragen der Implementation werden in ISO 14915 nicht behandelt. Die ergonomischen Anforderungen können durch sehr unterschiedliche Mechanismen eingehalten werden, z. B. das Bereitstellungssystem, eine Skriptsprache oder die Anwendung.

Ergonomie des logiciels pour les interfaces utilisateur multimédias - Partie 2: Navigation et contrôle multimédias (ISO 14915-2:2003)

L'ISO 14915-2:2003 fournit des recommandations et des exigences pour la conception d'interfaces utilisateur multimédias dans les domaines suivants : conception de l'organisation du contenu, problèmes liés à la navigation et au contrôle des médias. L'ISO 14915-2:2003 se limite à la conception de l'organisation du contenu et ne traite pas de la conception du contenu en général. Les problèmes de conception applicables à un média unique (par exemple la luminosité d'une séquence de film) ne sont abordés que dans le cadre des aspects ergonomiques des commandes destinées à l'utilisateur.
