D3PART: A new model for redistribution and plasticity of 3D user interfaces

Abstract

In this paper 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. We extend previous plasticity models with redistribution capabilities, which lets developers create applications where 3D content and interaction tasks can be automatically redistributed across the different dimensions at runtime.

Providing plasticity and redistribution for 3D user interfaces using the D3PART model

“…For instance, this content includes 3D meshes with complex materials and behaviors. That is why, in order to design 3D applications that handle plasticity, recasting and redistribution, as shown in Figure 3 taken from [22], our solution D3PART extends our previous plasticity models [21]. In this previous work we presented three models for the implementation of plastic 3DUI's.…”

“…With the plasticity models and the dynamic recasting mechanism introduced in the previous section, a developer can create an application that can be adapted to the capabilities of a wide variety of platforms. As shown in Figure 3 and described in [22] D3PART also includes a redistribution process that makes the integration of redistribution capacities totally transparent and automatic for the developer. The process consists of distributing the high level tasks and the virtual environment across the different dimensions: platform, display and user.…”

“…The abstraction facet contains the redistribution logic and the rendering presentation facet contains the parts that are dependent on the target 3D Fig. 6: With D3PART, the redistribution process is performed in four steps as shown in [22]. First, the different platforms connect to the redistribution server.…”

“…This paper is an extended version of [22]. Here, we further develop the related work part, give more details about the model implementation and we give additional examples of possible uses of D3PART.…”

Heterogeneous, Distributed Mixed Reality Applications. A Concept

“…Plasticity [7] takes into account variations on displays, user preferences, and devices in order to select at runtime the best interface possible. HDMRs do not concentrate on changes of the interface at runtime, but in the conditions that make such interface equivalent to all users from any particular hardware platform, given certain tasks.…”
