Webs i aplicacions mòbils: una aproximació des del punt de vista de l'experiència d'usuari

In this paper are presented and described the main characteristics of the different approaches of mobile website and mobile applications design, placing emphasis on the factors that determine a good user experience. Regarding the development of optimized websites for mobile devices, stand out among from other options the mobile-dedicated sites and, particularly, responsive websites as a preferred option. In terms of mobile applications development, there are three alternatives each with their possible advantages and disadvantages: the developed of native apps in the specific programming language of the device, the development of web applications with web standards and accessible from a traditional web browser, and the hybrid applications, that have some characteristics of native applications, but are developed with web standards

Eignung von virtueller Physik und Touch-Gesten in Touchscreen-Benutzerschnittstellen für kritische Aufgaben

The goal of this reasearch was to examine if modern touch screen interaction concepts that are established on consumer electronic devices like smartphones can be used in time-critical and safety-critical use cases like for machine control or healthcare appliances. Several prevalent interaction concepts with and without touch gestures and virtual physics were tested experimentally in common use cases to assess their efficiency, error rate and user satisfaction during task completion. Based on the results, design recommendations for list scrolling and horizontal dialog navigation are given.Das Ziel dieser Forschungsarbeit war es zu untersuchen, ob moderne Touchscreen-Interaktionskonzepte, die auf Consumer-Electronic-Geräten wie Smartphones etabliert sind, für zeit- und sicherheitskritische Anwendungsfälle wie Maschinensteuerung und Medizingeräte geeignet sind. Mehrere gebräuchliche Interaktionskonzepte mit und ohne Touch-Gesten und virtueller Physik wurden in häufigen Anwendungsfällen experimentell auf ihre Effizienz, Fehlerrate und Nutzerzufriedenheit bei der Aufgabenlösung untersucht. Basierend auf den Resultaten werden Empfehlungen für das Scrollen in Listen und dem horizontalen Navigieren in mehrseitigen Software-Dialogen ausgesprochen

Towards inclusive GIS in the Congo Basin: an exploration of digital map creation and an evaluation of map understanding by non-literate hunter-gatherers

Sustainable and socially just natural resource management is one of the fundamental development challenges humanity is facing today. Communities living in remote areas possess unique insights about their natural resources. While this knowledge is critical to climate change, it is difficult for them to engage in environmental protection. Geographic Information Science (GIS) plays a central role in resource management, as it is utilised in spatial decision making processes. However, the literature argues that its use is too challenging for marginalised communities. Working with indigenous hunter-gatherers in the Congo Basin without prior exposure to technology or maps, this research moves towards enabling them to become active stakeholders in decision making so that they understand how to capture environmental knowledge and gain power through ownership. (Participatory) GIS, Human Computer Interaction, Action Research and Citizen Science concepts are adapted to the local context to address the lack of mapping of these areas, and the increased understanding of if and how digital, high resolution orthographic maps incorporated in digital mapping tools can be understood by people with no prior exposure to maps and technology. Different set-ups of low-cost Unmanned Aerial Vehicles and consumer grade cameras were tested and evaluated for suitability to generate high-resolution maps in-situ for previously unmapped and disconnected contexts. Applying a computer log analysis approach to overcome local obstacles, three experiments were carried out to test whether the resulting aerial orthophotos are understood as a representation of familiar geographical landscapes. For each of the experiments, a bespoke app functioning without an internet connection was developed. The research shows that the majority of the 136 participants could find as well as edit known features on the map and all participating groups were able to utilise a map for a Treasure Hunt game. Additionally, a number of methodological amendments are proposed to allow standardised research methods to be applied in a context where usability experiments are significantly challenged
