Insights on the Design of InTml

Abstract

This paper describes some details about the design of InTml, the interaction techniques markup language. We explain three main elements in its architecture: a simple mixed reality (MR) based component model, a communication model between components that allows fusion of multimodal information at a fine level of granularity, and an indirection mechanism for dataflows that is useful to keep state inside a dataflow. We also briefly discuss the advantages we have found in the use of formal methods, model driven development, and encapsulation mechanisms. The purpose of this description is to make explicit the design rationale of these mechanisms, which may be fruitful for other developments in our field.

Many-core event evaluation

“…Allard and Raffin [2006] perform physics simulations using FlowVR [Allard et al 2004]. Hermann et al [2009;2010] perform parallel physics simulations at the body level using the KAAPI middleware [Gautier et al 2007] for dynamic load balancing using a work-stealing mechanism over a cluster of multiprocessors.…”

“…Related to dataflow in interactive general-purpose Virtual Reality (VR) applications, Figueroa [2010] presents an abstraction for parallel execution within the InTml interaction technique markup language. It provides a mechanism for node replacement in the dataflow allowing references to dynamic objects.…”

VR Development with InTml

“…In summary, our proposal describes how to retarget devices and interaction techniques in VR applications, as opposed to changes in graphic content only. More details about InTml and its implementation can be found at Figueroa et al (2008) and Figueroa (2010).…”
