Bridging the Gap: Developing 2D and 3D User Interfaces with the IDEAS Methodology (original) (raw)

The Three-Dimensional User Interface

Advances in Human Computer Interaction, 2008

This chapter introduced the three-dimensional user interface (3D UI). With the emergence of Virtual Environment (VE), augmented reality, pervasive computing, and other "desktop disengage" technology, 3D UI is constantly exploiting an important area. However, for most users, the 3D UI based on desktop is still a part that can not be ignored. This chapter interprets what is 3D UI, the importance of 3D UI and analyses some 3D UI application. At the same time, according to human-computer interaction strategy and research methods and conclusions of WIMP, it focus on desktop 3D UI, sums up some design principles of 3D UI. From the principle of spatial perception of people, spatial cognition, this chapter explained the depth clues and other theoretical knowledge, and introduced Hierarchical Semantic model of "UE", Scenario-based User Behavior Model and Screen Layout for Information Minimization which can instruct the design and development of 3D UI. This chapter focuses on basic elements of 3D Interaction Behavior: Manipulation, Navigation, and System Control. It described in 3D UI, how to use manipulate the virtual objects effectively by using Manipulation which is the most fundamental task, how to reduce the user's cognitive load and enhance the user's space knowledge in use of exploration technology by using navigation, and how to issue an order and how to request the system for the implementation of a specific function and how to change the system status or change the interactive pattern by using System Control. Finally through the case analysis, it highlighted the experience and interactive of 3D UI. And then it analyzed elements affecting 3D UI interactive mode from the Psychology, interactive design and information show. 3D UI has come to the transition time from the technology-driven to the design-driven. This section gives the readers a basic understanding of 3D UI. It focuses on the basic concepts, advantages and limitations between different latitude UI, its applications and the studying contents. 1.1 Concept of 3D UI 1.1.1 Definition of 3D UI With the development of computer hardware and software technology and the increased demand of application, digital terminal equipment diversification, such as cell phones, PDA (Pocket PC) terminals spread, and so on, that the time of Pervasive Computing has arrived.

Designing for 3D User Experience in Tablet Context Design and Early Phase User Evaluation of Four 3D GUIs

This article focuses on a possibility to have a personal three dimensional graphical user interface inside a virtual environment on a tablet device. We describe the visual design process and early phase user experience evaluation of four 3D GUIs in a virtual environment. A user evaluation was conducted by using a structured pair evaluation procedure, where we adapted the concept walkthrough method with non-functional visually high quality prototypes. In addition, we conducted a self-expression task, where participants were able to draw their idea of a 3D GUI on a touch screen tablet device. This evaluation provided us a lot of user feedback for the design, which we utilized in the final iterated designs. In addition, we point out many design issues relating to the visual design of the personal GUI in virtual environments in a touch screen context. Our user evaluation indicated that participants would like to have their personal 3D GUI in a virtual environment. However, the visual de...

Elements of a Three-dimensional Graphical User Interface

Human-Computer Interaction INTERACT ’97, 1997

The graphical user interface (GUI) is now firmly established as the preferred user interface for end users in most situations. Just as decreasing hardware prices and increasing hardware capabilities made two-and-a-hall dimensional (2!D) GUIs affordable in the early eighties and widespread in the ninetees, we believe declining hardware prices and increasing hardware capabilities will make three-dimensional (3D) GUIs possible and affordable in the near future. Three-dimensional GUIs raise many issues of design, metaphor and usability. In this paper we discuss elements of a prototype 3D GUI we are developing.

A Space Model for 3D User Interface Development

Computer-Aided Design of User Interfaces VI, 2009

Space deserves a special attention when designing 3D user interfaces. However, many proposed methods rely on simple sketches and/or maps. Besides, those methods usually leave aside the 2D interfaces that may be found in the 3D environment or that surround it. This chapter presents an attempt to formalize 2D and 3D spaces by the definition of a meta-model. This is one of three meta-models that have been defined in three-dimensional user interface development methodology, which is also described here along with some case studies, focusing the description on space.

3DUI-EF: Towards a Framework for Easy Empirical Evaluation of 3D User Interfaces and Interaction Techniques

2010

Designing usable and effective 3D User Interfaces and D Interaction Techniques is very challenging for Virtual Reality system developers and human factors specialists. Indeed, time consuming empirical evaluation is necessary to have an idea about the goodness of the D User Interface (3DUI) and the D Interaction Technique (3DIT) at the end of their development lifecycle. This may induce a huge loss of time if the result appears not to be satisfying in the end. Moreover, 3DUI evaluation is much more complex than 2D User Interfaces evaluation which is due to heterogeneous Virtual Reality (VR) devices and 3DIT. The aim of this work is to provide a framework allowing developers and experimenters to quickly evaluate 3DUIs and 3DITs during the design and the development lifecycle. The proposed framework is divided into two tools. The first one enables to create an evaluation protocol based on a knowledge database using two data mining algorithms, the "C4.5" to avoid from impossib...
