Long Paper:

A. Bigdelou, L. Schwarz, N. Navab An Adaptive Solution for Intra-operative Gesture-based Human-Machine Interaction International ACM Conference on Intelligent User Interfaces (IUI), Lissabon, Portugal, February 2012 (bib)

Computerized medical systems play a vital role in the operating room, however, sterility requirements and interventional workflow often make interaction with these devices challenging for surgeons. Typical solutions, such as delegating physical control of keyboard and mouse to assistants, add an undesirable level of indirection. We present a touch-less, gesture-based interaction system for the operating room that lets surgeons define a personalized set of gestures for controlling arbitrary medical computerized systems. Instead of using cameras for capturing gestures, we rely on a few wireless inertial sensors, placed on the arms of the surgeon, eliminating the dependence on illumination and line-of-sight. A discriminative gesture recognition approach based on kernel regression allows us to simultaneously classify performed gestures and to track the relative spatial pose within each gesture, giving surgeons fine-grained control of continuous parameters. An extensible software architecture enables a dynamic association of learned gestures to arbitrary intra-operative computerized systems. Our experiments illustrate the performance of our approach and encourage its practical applicability.

Demo Paper:

A. Bigdelou, L. Schwarz, T. Benz, N. Navab A Flexible Platform for Developing Context-Aware 3D Gesture-based Interfaces International ACM Conference on Intelligent User Interfaces (IUI), Lissabon, Portugal, February 2012 (bib)

In this paper, we introduce a flexible framework that can facilitate the definition of 3D gesture-based interfaces. Highlighting the need for context awareness in complex domains, such as the operating room, we argue how the proposed architecture can overcome integration challenges. Through a real-life scenario, an intra-operative medical image viewer, we demonstrate how the proposed framework can be used in practice to define user interfaces in collaborative environments, where the behavior and the system response can be adapted based on the current workflow stage and individual user requirements. Finally, we demonstrate how the defined interface can be manipulated using a high-level visual programming interface. The extensibility of the proposed architecture makes it applicable to a wide range of scenarios.
