Speech-gesture driven multimodal interfaces for crisis management
Rajeev Sharma,Mohammed Yeasin,N. Krahnstoever,Ingmar Rauschert,Guoray Cai,Isaac Brewer,Alan M. MacEachren,Kuntal Sengupta +7 more
TL;DR: The importance of multimodal interfaces in various aspects of crisis management is established and many issues in realizing successful speech-gesture driven, dialogue-enabled interfaces for crisis management are explored.
Proceedings ArticleDOI
A real-time framework for natural multimodal interaction with large screen displays
TL;DR: This paper presents a framework for designing a natural multimodal human computer interaction (HCI) system and found that the system performed according to its specifications in 95% of the cases and that users showed ad-hoc proficiency, indicating natural acceptance of such systems.
Proceedings ArticleDOI
Multimodal human-computer interaction for crisis management systems
TL;DR: Insight into the design aspects of the XISM system is provided, addressing the issues of extraction and fusion of gesture and speech modalities to allow more natural interactive behavior.
Journal ArticleDOI
Automatic acquisition and initialization of articulated models
TL;DR: This paper addresses the problem of automatic acquisition and initialization of articulated models from monocular video without any prior knowledge of shape and kinematic structure in a human-computer interaction context where articulated shape models have to be acquired from unknown users for subsequent limb tracking.
Proceedings ArticleDOI
Appearance management and cue fusion for 3D model-based tracking
N. Krahnstoever,Rajeev Sharma +1 more
TL;DR: This paper presents a systematic approach to acquiring model appearance information online for monocular model-based tracking and shows that the presented algorithm is able to robustly track a wide variety of targets under challenging conditions.
