Plasticity for 3D user interfaces

Journal on Multimodal User Interfaces

We propose D3PART (Dynamic 3D Plastic And Redistribuable Technology), a model to handle redistribution for 3D user interfaces. Redistribution consists in changing the components distribution of an interactive system across different dimensions such as, platform, display and user. Our work is based on previous models for the creation of 3D plastic user interfaces, interactive systems that can handle the context of use modifications while preserving usability. In our previous work, we proposed a task model, a device model and an application component model for the creation of plastic user interfaces that handle the 3D specificities. With D3PART, we extend these models in order to include redistribution capabilities. The final solution lets developers create applications where 3D content and tasks can be automatically redistributed across the different dimensions at runtime. The proposed redistribution process is based on a client-server architecture with a meta-user interface to control the redistri

Abstract Why is computer interaction using a 3D CAD (Computer Aided Design) tool such a hard task while an untrained child can easily build 3D buildings out of a LegoTM set? We believe that the reason lies in the current Human Computer interface (HCI). TUIs (Tangible User Interfaces) offer natural means of interaction with computers and have already been shown to simplify existing computerized applications and offer solutions for tasks that were considered to be “out of the scope” of human-computer interaction.

The paper presents a user study comparing the performance and usability of different input devices for precise manipulation of 3D objects: a regular mouse, a 3D mouse, and the gesture-based Leap Motion Controller. We show that the 3D mouse is well suited for the task, as it yielded the lowest rotation error rate and best overall usability, while tasks were completed as fast with the 3D mouse as with the regular mouse interface. The 3D mouse got an average System Usability Scale (SUS) score of 88.7, the regular mouse 72.4, while the Leap Motion Controller was barely suitable for the task with an average SUS score of 56.5. The study showed that users needed the most time to finish the tasks with the Leap Motion Controller and that its gestures were not as easy to learn as with the 3D mouse. This led us to conclude that the 3D mouse is currently the best input choice among the tested devices for 3D tasks that require both high precision, quick completion and a fast learning curve.

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.

In this chapter, we bring together the main results from the developments in plastic user interfaces (UI) and in multimodal UIs using a theoretic and conceptual perspective as a unifying approach. In particular, we provide an operational model for the notion of modality as well as for the combination of multiple modalities in terms of the CARE properties. Then, we clarify the problem space of UI plasticity and show how multimodality can be used as a means for UI adaptation.

The word 3D is defined as three dimensional models that display a picture or item in a form that appears to be physically present with a designated structure. Three-dimensional (3D), can also describe any object that occurs on a three-axis Cartesian coordinate system, a Cartesian system is basically a fancy way of describing the X and Y axes which are horizontal and vertical axis, but the inclusive of the third axis Z which is make it to be 3D of which the Z axis represent the depth.3D interaction is a form of human-machine interaction where users are able to move and perform interaction in 3D space. Both human and machine process information where the physical position of elements in 3D space. The main features of these 3D applications are immersion, interactivity, and involvement. Immersion holds the user's attention. Interactivity is related to how responsive the application is to user actions and Involvement has to do with engaging the user's interest in the underlying activity.3D interaction techniques are selection and manipulation, navigation, system control and symbolic inputs. Its application is in the area of Exploring Complex Data, Visualizations with the Cubic Mouse, Multimodal Interfaces in VEs Multimodal interaction, and VEs for Design Education Architectural design.

I nteraction devices for virtual environments have evolved slowly. Most systems still employ tracked wands or some type of gloves, as in the first days of virtual reality systems. Only recently have prop-based interfaces in combination with two-handed interaction techniques become increasingly popular. Passive realworld props augment interaction through tactile feedback and often lead to more intuitive interaction techniques. The Cubic Mouse 1,2 is a new, 3D input device based on the prop idea. It consists of a cube-shaped box with three perpendicular rods passing through its center (Figure 1). We use a six-degrees-of-freedom (6-DOF) tracker embedded in the Cubic Mouse to track the device's position and orientation. The rods can be pushed and pulled, allowing the constrained input of three degrees of freedom. We call this "translation only" version the 3-DOF Cubic Mouse. Our latest version of the device, the 6-DOF Cubic Mouse, also allows rotation of the rods, which adds another three DOF. Altogether, we have a total of 12 analog degrees of freedom available with the Cubic Mouse, six DOF through the tracking and another six through the rods. These 12 DOF can be assigned to interaction tasks in various ways. In addition, the Cubic Mouse has six application-programma-ble control buttons mounted on one face and one button at both ends of each rod.
