3D Virtual Environments

Traditional interaction devices such as computer mice and keyboards do not adapt very well to immersive envi-ronments, since they were not necessarily designed for users who may be standing or in movement. Moreover, in the current inte-raction model for immersive environments, based on wands and 3D mice, a change of context is necessary in order to execute non-immersive tasks. These constant context changes from im-mersive to 2D desktops introduce a rupture in user interaction with the application. The objective of this work is to study how to adapt interaction techniques from touch surface based systems to 3D virtual environments to reduce this physical rupture from the fully immersive mode to the desktop paradigm. In order to do this, a wireless glove (v-Glove) that maps to a touch interface in a vir-tual reality immersive environment was developed, enabling it to interact in 3D applications. The glove has two main functionalities: tracking the position of the user's index finger and vibrating the fingertip when it reaches an area mapped in the interaction space to simulate a touch feeling. Quantitative and qualitative analysis were performed with users to evaluate the v-Glove, comparing it with a gyroscopic 3D mouse.

3D Virtual Environments

The introduction of embedded sensors in smartphones and tablets allowed the use of these devices to interact with virtual environments. These devices also have the possibility of including additional information and performing naturally non-immersive tasks. This work presents a 3D interaction tablet-based tool, which allows the aggregation of all major 3D interaction tasks, such as navigation, selection, manipulation, system control and symbolic input. This tool is for generalpurpose systems, as well as, engineering applications. Generally this kind of application uses specific interaction devices with four or more degrees of freedom and a common keyboard and mouse for tasks that are naturally non-immersive, such as symbolic input (e.g., text or number input). This article proposes a new tablet-based device that can perform all these major tasks in an immersive environment. It also presents a study case of the use of the device and some user tests.

3D Virtual Environments

A set of rules is presented for the design of interfaces that allow virtual objects to be manipulated in 3D virtual environments (VEs). The rules differ from other interaction techniques because they focus on the problems of manipulating objects in cluttered spaces rather than open spaces. Two experiments are described that were used to evaluate the effect of different interaction rules on participants' performance when they performed a task known as “the piano mover's problem.” This task involved participants in moving a virtual human through parts of a virtual building while simultaneously manipulating a large virtual object that was held in the virtual human's hands, resembling the simulation of manual materials handling in a VE for ergonomic design. Throughout, participants viewed the VE on a large monitor, using an “over-the-shoulder” perspective. In the most cluttered VEs, the time that participants took to complete the task varied by up to 76% with different combinations of rules, thus indicating the need for flexible forms of interaction in such environments.

In this paper, a new type of interaction environment, the multiscale collaborative virtual environment (mCVE), is proposed to support multiple users working together at different scale levels. This paper introduces the concept of multiscale collaboration in the context of 3D virtual environments and describes the benefits of multiscale collaboration for understanding and managing large structures that present important features at different scale levels. After a discussion on the design and implementation of multiscale tools to support the visualization of structures, cross-scale information sharing, and cross-scale action, the paper presents an experimental study showing that cross-scale collaboration can improve user performance.

Rehabilitation Tasks

We describe a graphical narrative editor that we have developed for the design of serious games for cognitive neurorehabilitation. The system is addressed to neuropsychologists. It is aimed at providing them an easy, user-friendly, and fast way of specifying the therapeutical contents of the rehabilitation tasks that constitute the serious games. The editor takes as input a description of the virtual task environment and the actions allowed inside. Therapists use it to describe the actions that they expect patients to do in order to fulfill the goals of the task and the behavior of the game if patients do not reach their goals. The output of the system is a complete description of the task logic. We have designed a 3D game platform that provides to the editor a description the 3D virtual environments, and that translates the task description created in the editor into the task logic. The main advantage of the system is that it is fully automatic, it allows therapists to interactively design the tasks and immediately validate them by realizing it virtually. We describe the design of the two applications and present the results of system testing.
