An investigation into the problems of user oriented interfaces in mobile applications

The purpose of this paper is the analysis and evaluation of the mobile interface design. This study consisted of a random sample of 55 user interfaces for mobile applications. In addition, the restriction of all the components of the user interface quantified. An analysis was conducted of these interfaces, in order to represent graphically. Then, evaluated and produced the following results: First, the smaller number of pages in the application is better. Second, decreasing the navigation bars, buttons and menus in user interfaces for mobile applications gives additional space on the screen, making the application easy to use and maintaining the context. Third, diversity, the use of tools ensures good interaction with the user. Finally, a range of results for the design of the user interface and some ideas are provided about what should be taken of these results in mind when designing interfaces for mobile applications

User-Centered Guidelines for Design of Mobile Applications

In this study, interviews were conducted to derive user-centered guidelines for the interface design of mobile applications. These guidelines cover general design issues in input, display, navigation, and feedback. They address five out of seven elements that describe effective mobile commerce interface design proposed by Lee and Benbasat [7]. Compared to guidelines obtained in prior studies, the guidelines derived from this study are user-centered and can be apply to multiple form factors. The comparison between e-commerce and mobile commerce design guidelines suggest that the mobile context plays the most important role in designing mobile commerce interfaces

Direct combination: a new user interaction principle for mobile and ubiquitous HCI

Direct Combination (DC) is a recently introduced user interaction principle. The principle (previously applied to desktop computing) can greatly reduce the degree of search, time, and attention required to operate user interfaces. We argue that Direct Combination applies particularly aptly to mobile computing devices, given appropriate interaction techniques, examples of which are presented here. The reduction in search afforded to users can be applied to address several issues in mobile and ubiquitous user interaction including: limited feedback bandwidth; minimal attention situations; and the need for ad-hoc spontaneous interoperation and dynamic reconfiguration of multiple devices. When Direct Combination is extended and adapted to fit the demands of mobile and ubiquitous HCI, we refer to it as Ambient Combination (AC) . Direct Combination allows the user to exploit objects in the environment to narrow down the range of interactions that need be considered (by system and user). When the DC technique of pairwise or n-fold combination is applicable, it can greatly lessen the demands on users for memorisation and interface navigation. Direct Combination also appears to offers a new way of applying context-aware information. In this paper, we present Direct Combination as applied ambiently through a series of interaction scenarios, using an implemented prototype system

Designing Mobile Augmented Reality interfaces for locative games and playful experiences

Mobile Augmented Reality (MAR) has predominantly been used in locative games and playful experiences for the presentation on virtual game objects in conjunction with separate 2-D maps for navigation. This distinct switch in interaction modalities can detract from the game play experience and will arguably be less relevant for AR glasses. Therefore this research considers the application techniques from graphic design to MAR interfaces to provide an effective means of navigation through a physical game space without maps. To illustrate this approach we present a MAR application that provides a playful way for visitors to explore a small rural village in both space and time in relation to its main cultural event, the annual Scarecrow Festival. In particular we present the considerations that designers must address when creating purely augmented reality navigation interfaces through the design, implementation, and user evaluation of the application scARecrow Time Machine

User-Accustomed Interaction: An Usability Approach for Designing Mobile Application for Novice and Expert Users

The development of smartphone applications is prevailing globally, including the underserved communities consisting of a huge group of novice users. In spite of the growing number of novice users, we hardly consider usability for users with varying expertise level when we evaluate performance and satisfaction with usage of mobile applications. In this study, we argue that it is not suitable to design one interface for all users of progressively varying communities. Based on theories in design science research, we propose a user-accustomed approach to adapt mobile applications that integrate three types of interaction elements, namely localization, structural navigation and illustration. In an investigation of the proposed approach on mobile application, we empirically proved the effects of user-accustomed interaction techniques on performance and satisfaction between novice and expert users. The findings provide significant theoretical and practical implications for design and implementation of user interfaces on mobile application

Model-driven GUI generation and navigation for android BIS apps

This paper presents our approach for producing graphical user interfaces (GUIs) for functionally rich business information system (BIS) prototypes, upon a mobile platform. Those prototypes are specified with annotated UML class diagrams. Navigation in the generated GUIs is allowed through the semantic links that match the associations and cardinalities among the conceptual domain entities, as expressed in the model. We start by reviewing the Android scaffolding for producing flexible GUIs for mobile devices. The latter can present rather different displays, in terms of size, orientation and resolution. Then we show how our model-based generative technique allows producing prototypes that match both the Android GUIs requirements, while implementing our model-driven approach for user navigation.info:eu-repo/semantics/publishedVersio

Towards Rapid Generation and Visualisation of Large 3D Urban Landscapes for Mobile Device Navigation

In this paper a procedural 3D modelling solution for mobile devices is presented based on scripting algorithms allowing for both the automatic and also semi-automatic creation of photorealistic quality virtual urban content. The combination of aerial images, GIS data, 2D ground maps and terrestrial photographs as input data coupled with a user-friendly customized interface permits the automatic and interactive generation of large-scale, accurate, georeferenced and fully-textured 3D virtual city content, content that can be specially optimized for use with mobile devices but also with navigational tasks in mind. Furthermore, a user-centred mobile virtual reality (VR) visualisation and interaction tool operating on PDAs (Personal Digital Assistants) for pedestrian navigation is also discussed. Via this engine, the import and display of various navigational file formats (2D and 3D) is supported, including a comprehensive front-end user-friendly graphical user interface providing immersive virtual 3D navigation

Using Sound to Enhance Users’ Experiences of Mobile Applications

The latest smartphones with GPS, electronic compass, directional audio, touch screens etc. hold potentials for location based services that are easier to use compared to traditional tools. Rather than interpreting maps, users may focus on their activities and the environment around them. Interfaces may be designed that let users search for information by simply pointing in a direction. Database queries can be created from GPS location and compass direction data. Users can get guidance to locations through pointing gestures, spatial sound and simple graphics. This article describes two studies testing prototypic applications with multimodal user interfaces built on spatial audio, graphics and text. Tests show that users appreciated the applications for their ease of use, for being fun and effective to use and for allowing users to interact directly with the environment rather than with abstractions of the same. The multimodal user interfaces contributed significantly to the overall user experience
