Abstract
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.
Highlights
Keyboard and mouse are often used for WIMP (Windows, Icons, Menu, Pointers) interfaces and normally have only two degrees of freedom
The current availability of mobile devices such as tablets with sensors and multi-touch screens is an incentive to their use in three-dimensional interaction techniques
Two prominent problems in this field are the need to naturally control non-immersive tasks, such as symbolic input, and the learning curve required for handling devices created for 3D interaction
Summary
Keyboard and mouse are often used for WIMP (Windows, Icons, Menu, Pointers) interfaces and normally have only two degrees of freedom. A very common way to mix the two forms is to use users’ movements to control the point of view on the virtual environment, deforming the projection matrix of the environment according to the user’s position within the immersive environment, using specific devices such as the Flystick for navigation, manipulation and selection tasks. In one of these works, by Cirio et al [25], a technique called Real Walking is presented. Other studies in the literature propose the use of mappings elements of WIMP interfaces in virtual three dimensional environments, including: VEWL that abstracts concepts of windows and buttons [29]; Liang et al introduces the concept of ring menus [6] and Gerber et al, spin menus [30]
