“…Using the data flow model to describe the user interface for virtual environments traces back to an early virtual reality program named Body Electric [10] from VPL. And it also agrees with the previous work of Steed and Slater [18] that investigated on the immersive authoring in a virtual environment.…”

“…However, the system remained as a concept and was never implemented. Steed and Slater [18] developed a system that visualized the links of data flow between the virtual objects, making users able to manipulate them directly. Lee et al [11] pointed out that behavior authoring tasks could also benefit from direct 3D interactions and proposed to use a programming by demonstration approach for authoring virtual object behaviors.…”

In this paper we suggest a new approach for authoring tangible augmented reality applications, called 'immersive authoring.' The approach allows the user to carry out the authoring tasks within the AR application being built, so that the development and testing of the application can be done concurrently throughout the development process. We describe the functionalities and the interaction design for the proposed authoring system that are specifically targeted for intuitive specification of scenes and various object behaviors. Several cases of applications developed using the authoring system are presented. A small pilot user study was conducted to compare the proposed method to a non-immersive approach, and the results have shown that the users generally found it easier and faster to carry out authoring tasks in the immersive environment.

“…Work in AR authoring draws on the rich heritage of authoring environments in computer graphics and virtual reality. Previous work [8,10] showed that visual programming techniques could be used to develop 3D interactive graphics applications. This approach is being commercialized through software from Virtools (www.virtools.com) and EON Reality (www.eonreality.com) for the visual programming of virtual environments; developers connect icons and specify object properties to create virtual reality applications.…”

“…The efficiency of any particular technique seems to be dependent first on the task and also on user preference [3], and thus some systems allow dynamic customization of interaction techniques (e.g. [30]). In a VE system we typically have fairly precise 3D tracking of some of the user's limbs, our user has a one to one egocentric view of the environment consistent with the tracking and there is a 3D representation of the simulated environment.…”

Selection is one of the fundamental building blocks of all interactive virtual environment systems. Selection is the ability of the user to specify which object, or sub-part of an object in the environment, is the target for subsequent actions. Examples include selecting 3D buttons thus invoking an action or selecting a target upon which an action will occur. Selection is also an implicit or explicit part of manipulation techniques.In a virtual environment selection can be performed in many different ways. In this paper we develop a generalized model of how interaction is and could be performed in virtual environments using 3D gestures. The purpose of this model is to highlight some potential areas for development and evaluation of novel selection techniques. The model is based on an analysis of the complexity of selection. We develop a model for selection that is based on time-varying scalar fields (TVSFs) that encompasses a very broad range of existing techniques. This model will be abstract, in that a direct implementation will be prohibitively complex, but we show how some standard implementation strategies are good approximations to the formal model.
