This study investigates the 404 error and in what way feedback should be given to the user in an error message to generate a good user experience. To investigate this, data was gathered from 1) a literature review looking at previous studies in User Experience Design, as well as different models to evaluate ease of use and perceived usefulness, 2) a pre-study questionnaire with nine participants who were asked questions related to error messages and feedback in general, and 3) two user tests; the first including 16 participants and the second including 46 participants. During the user tests the participants interacted with a prototype of a website that included 404 error messages. In the first user test the participants' user experience was evaluated based on the TAM model, including perceived usefulness and perceived ease of use. The second user study focused more on text and illustrations and their effects on the user experience. Three versions of texts were tested, formal, apologetic and amusing. The illustrations either included a character or an object. The result showed that, in general, the users preferred formal texts, as well as illustrations that included a character. The result also suggested that there is not one type of feedback that fits all users, in order to generate a good user experience, it is important to know the audience.

The usability of a software product is dependent on the end-user and the context of use. Having a user-friendly user interface that is appealing and easy to learn and use is essential for improved human productivity. However, this is not always the case. For instance, the computer-based documentation system Siebel used within the elderly care system; is perceived by most nursing assistants as complicated. The goal here is to evaluate the usability of the system's user interface, applying the usability metrics stated in the ISO/IEC-9126-1 standards to quantify the effectiveness, efficiency, and user satisfaction of Siebel’s documentation system. A prototype user interface was developed for comparison with the current system. Likert-scale five-point scale; System Usability Scale (SUS) questionnaires were used to measure User satisfaction. The results mirrored that the participants preferred the newly developed prototype user interface to the existing user interface

En esta investigación se evaluó la influencia de los principios de jerarquía visual en la aprendibilidad de las interfaces de videojuegos de administración de recursos, a lo cual se postuló la hipótesis de que la jerarquía visual aplicada en el diseño de la interfaz de usuario en juegos de este género influyen de manera positiva en la aprendibilidad, facilitando el reconocimiento de los elementos gráficos y la memorización de los pasos a realizar para lograr la victoria disminuyendo la posibilidad de abandono del juego por parte de jugadores nuevos. Para llegar a este supuesto, se analizó documentalmente dos videojuegos del género Estrategia en Tiempo Real desarrollados del 2008 al 2018. De igual manera, se realizaron pruebas de usabilidad en dichos videojuegos y, consecuentemente, encuestas que midan la aprendibilidad según la opinión de los participantes. Los resultados del análisis documental sugieren la aplicación de los principios de semejanza, región común, proximidad y de contraste. En los resultados de las pruebas de usabilidad y encuestas se registró que los usuarios consideran que el ordenamiento de los elementos gráficos les ayudó a realizar las acciones dictadas, memorizarlas y usarlas de manera más rápida para poder conseguir la victoria. Podemos concluir que existe una influencia positiva de la jerarquía visual en la velocidad y eficacia de aprendizaje de las interfaces en los videojuegos del género estudiado y, que la aplicación de los principios busca el logro de uso en lugar de un orden de importancia de los elementos del juego. / In this investigation we analyzed the influence of the principles of visual hierarchy in the learnability of resource management video game interfaces, to which a hypothesis was postulated regarding how visual hierarchy applied to user interface design on games of this genre influence positively in the learnability, making easier the recognition of graphic elements and the memorization of the steps to achieve victory lowering the possibility of game quitting in new players. To achieve this supposition, two Real Time Strategy video games that were developed from 2008 to 2018 were analyzed. Similarly, usability tests of such games were made, and, therefore, surveys that measure the learnability from the participants standpoint. The results of the documentary analysis suggest that the application of the principles of similarity, common fate, proximity and contrast. In the results of the usability tests and surveys it was recorded that the arrangement of graphic elements helped them to achieve the dictated tasks, memorizing them and using them in the fastest way to achieve victory. We can conclude that there’s a positive influence of visual hierarchy in the speed and effectiveness of learning from the videogame interfaces of the studied genre and, that the application of the principles look for a successful experience rather than just a hierarchy order between the game assets. / Trabajo de investigación

Color correction and grading are processes when fixing colors in recorded footage in Post-Production. The process of the two mentioned is a mix of technical adjustments and creativity. Color correction adjusts the colors between the clips/scenes so they match and look as natural or unique as possible. Grading is about the process of enhancing the look of a footage to achieve a certain style, it is of a more creative nature.Today, color correcting and grading are performed using desktop applications. The process means that recorded material is sent to the colorist from the set where it is received and downloaded to the computer where the work is performed. When the processing is considered complete, it is sent back to the recording team. This could be considered time consuming, and this process could be improved by using Accurate Video which is a web based program. Today, there are no features for color correction and grading in Accurate Video. The aim of this study was to design a User Interface (UI) for color correction and grading tools for Accurate Video application that meet the goals and needs of the people in this field of work, i.e. colorists. Based on literature studies including design guidelines, studies of what existing professional editing programs look like and what Accurate Video looks like, as well as interviews with colorists, a prototype was developed.

Die zunehmende Gewöhnung von Benutzern an neue Interaktionskonzepte und Endgeräte ermöglicht deren Einführung in industriellen Umgebungen. Daraus folgen Anwendungsszena-rien, in denen es, selbst während der Bearbeitung einer einzelnen Arbeitsaufgabe, zu häufigen Änderungen in der Zusammensetzung der verwendeten Geräte kommt. Dies motiviert die Entwicklung migrierbarer Benutzungsschnittstellen (MUI). In diesem Beitrag stellen wir zu-nächst die anerkannte Theorie der MUIs vor, inklusive verschiedener Klassifikationsmerkma-le und spiegeln diese an den Anforderungen der Automatisierungstechnik. Anhand dessen diskutieren wir anschließend zwei Anwendungsszenarien. Die Analyse verwandter Arbeiten zeigt auf, dass existierende Ansätze nur eingeschränkt in diesen Szenarien eingesetzt werden können. Am Ende stellen wir eine Fallstudie vor, die die Anwendbarkeit von MUIs in industriel-len Prozessvisualisierungen demonstriert.:1. Einleitung 2.

Zusammenfassung und Ausblick / Due to familiarization of users with modern interaction concepts and devices, they become interesting for industrial environments as well. These devices enable use cases where users change the set of applied devices, even during handling one single task. This fosters the de-sign of migratory user interfaces (MUI) which can be transferred freely between devices, in order to follow according to a user’s device changes. Hence, in this paper the generally ac-cepted theory, including a set of identified classifiers for MUIs, is being analyzed with respect to the demands of the domain of industrial process visualizations. Moreover, we discuss two use cases. Our review of the related work revealed only a limited applicability in those use cases. In order to demonstrate an MUI’s usefulness in industrial process visualizations, we finally present our own case study.:1. Einleitung 2.

Anwendungen unter Einsatz von Augmented Reality (AR)-Technologien gewinnen zuneh-mend an Relevanz in diversen industriellen Anwendungen, zum Beispiel für Produktpräsenta-tionen, Ausbildung und Lehre, Engineering, etc. Bei der Entwicklung solcher Anwendungen – im Speziellen von Bedien- und Beobachtungslösungen – müssen verschiedene Normen und Richtlinien beachtet werden, um zu gewährleisten, dass Anforderungen an die Betriebssi-cherheit in der jeweiligen Anlage eingehalten werden. In diesem Beitrag sollen einige Aspekte bezüglich der Anwendbarkeit solcher Richtlinien auf AR Anwendungen untersucht werden. Darüber hinaus werden weitere Aspekte betrachtet, die bei der Einführung von AR Anwen-dungen im großen Maßstab relevant sind, wie etwa die durchgängige Nutzbarkeit von CAD-Anlagenmodellen zur automatischen Erzeugung von AR-Lösungen. Schließlich stellen wir eine Fallstudie einer AR-Anwendung für eine prozesstechnische Kleinversuchsanlage vor.:1. Einleitung 2. Entwicklungsphasen von AR-Anwendungen 3.

Danksagung / Augmented Reality (AR) applications gain more and more relevance in various industrial ap-plications lately, e. g. for product presentations, education, engineering, etc. In the industrial domain, especially in process supervision applications, a number of standards and guidelines have been established to ensure that the design of user interfaces meets the safety require-ments of plants or factories. Hence, we seek an evaluation if these guidelines can be applied to AR applications. Moreover, there are other aspects to consider in case AR solutions shall be applied on a larger scale in industrial applications. Thus, it is being discussed whether CAD plant models can be used to generate AR applications automatically. Finally, in this contribu-tion, we present the first preliminary results of a case study on the application of those stand-ards to a visual AR application for in-field inspection and servicing scenarios.:1.
