EUROGRAPHICS ’0x/ N.N. and N.N. STAR – State of The Art Report A Survey of Interaction Techniques for Interactive 3D Environments Jacek Jankowski and Martin Hachet Inria Bordeaux, France Abstract Various interaction techniques have been developed for interactive 3D environments. This paper presents an up- to-date and comprehensive review of the state of the art of non-immersive interaction techniques for Navigation, Selection & Manipulation, and System Control, including a basic introduction to the topic, the challenges, and an examination of a number of popular approaches. We hope that this survey can aid both researchers and devel- opers of interactive 3D applications in having a clearer overview of the topic and in particular can be useful for practitioners and researchers that are new to the field of interactive 3D graphics.

ABOUT PROGRAMS AND OPERATING SYSTEMS Any time a task is performed on a computer, it is done through a program. For the user, the program is the application – the tool – for accomplishing a task. For the computer, it is a set of instructions on knowing how to perform this task. Examples of programs include Internet Explorer and Microsoft Word. The most important program overall is the operating system, which manages all of the computer’s resources and decides how to treat input from the user. There are several different operating systems in circulation, such as Mac O/S and Linux. However, far and away, the most commonly-used operating system is Microsoft Windows. (Note that Microsoft is just the name of the company that makes Windows, and that there are several versions of Windows. In 2012 all the computers in the lab were updated to the version of Windows called Windows 7.

Like human–computer interaction (HCI), it draws from many disciplines and has links to a wide variety of topics. In this chapter, we briefly describe the history of 3D UIs to set the stage for the rest of the book. We also present a 3D UI “roadmap” that posi- tions the topics covered in this book relative to associated areas. After reading this chapter, you should have an understanding of the origins of 3D UIs and its relation to other fields, and you should know what types of information to expect from the remainder of this book. 2.1. History of 3D UIs The graphical user interfaces (GUIs) used in today’s personal computers have an interesting history. Prior to 1980, almost all interaction with com- puters was based on typing complicated commands using a keyboard. The display was used almost exclusively for text, and when graphics were used, they were typically noninteractive. But around 1980, several technologies, such as the mouse, inexpensive raster graphics displays, and reasonably priced personal computer parts, were all mature enough to enable the first GUIs (such as the Xerox Star). With the advent of GUIs, UI design and HCI in general became a much more important research area, since the research affected everyone using computers.

  • The Three-Dimensional User Interface
    32 The Three-Dimensional User Interface Hou Wenjun Beijing University of Posts and Telecommunications China 1. Introduction 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.

What is Interaction for Data Visualization? Evanthia Dimara and Charles Perin∗ Abstract—Interaction is fundamental to data visualization, but what “interaction” means in the context of visualization is ambiguous and confusing. We argue that this confusion is due to a lack of consensual definition. To tackle this problem, we start by synthesizing an inclusive view of interaction in the visualization community – including insights from information visualization, visual analytics and scientific visualization, as well as the input of both senior and junior visualization researchers. Once this view takes shape, we look at how interaction is defined in the field of human-computer interaction (HCI). By extracting commonalities and differences between the views of interaction in visualization and in HCI, we synthesize a definition of interaction for visualization.

  • A Review of User Interface Design for Interactive Machine Learning
    1 A Review of User Interface Design for Interactive Machine Learning JOHN J. DUDLEY, University of Cambridge, United Kingdom PER OLA KRISTENSSON, University of Cambridge, United Kingdom Interactive Machine Learning (IML) seeks to complement human perception and intelligence by tightly integrating these strengths with the computational power and speed of computers. The interactive process is designed to involve input from the user but does not require the background knowledge or experience that might be necessary to work with more traditional machine learning techniques. Under the IML process, non-experts can apply their domain knowledge and insight over otherwise unwieldy datasets to find patterns of interest or develop complex data driven applications. This process is co-adaptive in nature and relies on careful management of the interaction between human and machine. User interface design is fundamental to the success of this approach, yet there is a lack of consolidated principles on how such an interface should be implemented. This article presents a detailed review and characterisation of Interactive Machine Learning from an interactive systems perspective. We propose and describe a structural and behavioural model of a generalised IML system and identify solution principles for building effective interfaces for IML. Where possible, these emergent solution principles are contextualised by reference to the broader human-computer interaction literature. Finally, we identify strands of user interface research key to unlocking more efficient and productive non-expert interactive machine learning applications.

  • Interaction Design and Children
    Foundations and TrendsR in Human–Computer Interaction Vol. 1, No. 4 (2007) 277–392 c 2008 J. P. Hourcade DOI: 10.1561/1100000006 Interaction Design and Children Juan Pablo Hourcade University of Iowa, USA, [email protected] Abstract Children are increasingly using computer technologies as reflected in reports of computer use in schools in the United States. Given the greater exposure of children to these technologies, it is imperative that they be designed taking into account children’s abilities, interests, and developmental needs. This survey aims to contribute toward this goal through a review of research on children’s cognitive and motor development, safety issues related to technologies and design method- ologies and principles. It also provides and overview of current research trends in the field of interaction design and children and identifies chal- lenges for future research. To understand children’s developmental needs it is important to be aware of the factors that affect children’s intellectual development. This survey analyzes the relevance of constructivist, socio-cultural, and other modern theories with respect to the design of technologies for chil- dren. It also examines the significance of research on children’s cognitive development in terms of perception, memory, symbolic representation, problem solving, and language. Since interacting with technologies most often involves children’s hands this survey also reviews literature on children’s fine motor development including manipulation and reach- ing movements. Just as it is important to know how to aid children’s development it is also crucial to avoid harming development. This survey summarizes research on how technologies can negatively affect children’s physical, intellectual, social, emotional, and moral devel- opment.

  • Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome
    Remove ANY TOOLBAR from Internet Explorer, Firefox and Chrome Browser toolbars have been around for years, however, in the last couple of months they became a huge mess. Unfortunately, lots of free software comes with more or less unwanted add-ons or browser toolbars. These are quite annoying because they may: Change your homepage and your search engine without your permission or awareness Track your browsing activities and searches Display annoying ads and manipulate search results Take up a lot of (vertical) space inside the browser Slow down your browser and degrade your browsing experience Fight against each other and make normal add-on handling difficult or impossible Become difficult or even impossible for the average user to fully uninstall Toolbars are not technically not a virus, but they do exhibit plenty of malicious traits, such as rootkit capabilities to hook deep into the operating system, browser hijacking, and in general just interfering with the user experience. The industry generally refers to it as a “PUP,” or potentially unwanted program. Generally speaking, toolbars are ad-supported (users may see additional banner, search, pop-up, pop-under, interstitial and in-text link advertisements) cross web browser plugin for Internet Explorer, Firefox and Chrome, and distributed through various monetization platforms during installation. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that the installed toolbar is a virus. For example, when you install iLivid Media Player, you will also agree to change your browser homepage to search.conduit.com, set your default search engine to Conduit Search, and install the AVG Search-Results Toolbar.
