Schnauer, Christian, Fukushi, Kenichiro, Olwal, Alex, Kaufmann, Hannes and Raskar, Ramesh (2012): Multimodal motion guidance: techniques for adaptive and dynamic feedback. In: Proceedings of the 2012 International Conference on Multimodal Interfaces 2012. pp. 133-140.

The ability to guide human motion through automatically generated feedback has significant potential for applications in areas, such as motor learning, human-computer interaction, telepresence, and augmented reality. This paper focuses on the design and development of such systems from a human cognition and perception perspective. We analyze the dimensions of the design space for motion guidance systems, spanned by technologies and human information processing, and identify opportunities for new feedback techniques. We present a novel motion guidance system, that was implemented based on these insights to enable feedback for position, direction and continuous velocities. It uses motion capture to track a user in space and guides using visual, vibrotactile and pneumatic actuation. Our system also introduces motion retargeting through time warping, motion dynamics and prediction, to allow more flexibility and adaptability to user performance.

DeVincenzi, Anthony, Yao, Lining, Ishii, Hiroshi and Raskar, Ramesh (2011): Kinected conference: augmenting video imaging with calibrated depth and audio. In: Proceedings of ACM CSCW11 Conference on Computer-Supported Cooperative Work 2011. pp. 621-624.

The proliferation of broadband and high-speed Internet access has, in general, democratized the ability to commonly engage in videoconference. However, current video systems do not meet their full potential, as they are restricted to a simple display of unintelligent 2D pixels. In this paper we present a system for enhancing distance-based communication by augmenting the traditional video conferencing system with additional attributes beyond two-dimensional video. We explore how expanding a system's understanding of spatially calibrated depth and audio alongside a live video stream can generate semantically rich three-dimensional pixels containing information regarding their material properties and location. We discuss specific scenarios that explore features such as synthetic refocusing, gesture activated privacy, and spatiotemporal graphic augmentation.

Zizka, Jan, Olwal, Alex and Raskar, Ramesh (2011): SpeckleSense: fast, precise, low-cost and compact motion sensing using laser speckle. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 489-498.

Motion sensing is of fundamental importance for user interfaces and input devices. In applications, where optical sensing is preferred, traditional camera-based approaches can be prohibitive due to limited resolution, low frame rates and the required computational power for image processing. We introduce a novel set of motion-sensing configurations based on laser speckle sensing that are particularly suitable for human-computer interaction. The underlying principles allow these configurations to be fast, precise, extremely compact and low cost. We provide an overview and design guidelines for laser speckle sensing for user interaction and introduce four general speckle projector/sensor configurations. We describe a set of prototypes and applications that demonstrate the versatility of our laser speckle sensing techniques.

Second Skin aims to combine three-dimensional motion tracking with real-time tactile feedback for the purpose of improving users' motor-learning ability. The system tracks a user's body and limb movements as he or she is performing an action, and the user is given automatic, real-time tactile feedback to aid in the correction of movement and position errors. A number of components integral to the motion tracking and tactile feedback systems must be bound to the user's body, and as such, an important goal is to design a lightweight and minimally inhibitive wearable suit that contains all of these elements.

In: Proceedings of the 2005 ACM Symposium on User Interface Software and Technology 2005. pp. 73-82.

Designing interfaces for interactive handheld projectors is an exiting new area of research that is currently limited by two problems: hand jitter resulting in poor input control, and possible reduction of image resolution due to the needs of image stabilization and warping algorithms. We present the design and evaluation of a new interaction technique, called zoom-and-pick, that addresses both problems by allowing the user to fluidly zoom in on areas of interest and make accurate target selections. Subtle design features of zoom-and-pick enable pixel-accurate pointing, which is not possible in most freehand interaction techniques. Our evaluation results indicate that zoom-and-pick is significantly more accurate than the standard pointing technique described in our previous work.

Bimber, Oliver and Raskar, Ramesh (2005): Spatial Augmented Reality: Merging Real and Virtual Worlds. A K Peters, Ltd

Like virtual reality, augmented reality is becoming an emerging platform in new application areas for museums, edutainment, home entertainment, research, industry, and the art communities using novel approaches which have taken augmented reality beyond traditional eye-worn or hand-held displays. In this book, the authors discuss spatial augmented reality approaches that exploit optical elements, video projectors, holograms, radio frequency tags, and tracking technology, as well as interactive rendering algorithms and calibration techniques in order to embed synthetic supplements into the real environment or into a live video of the real environment.

Projection technology typically places several constraints on the geometric relationship between the projector and the projection surface to obtain an undistorted, properly sized image. In this paper we describe a simple, robust, fast, and low-cost method for automatic projector calibration that eliminates many of these constraints. We embed light sensors in the target surface, project Gray-coded binary patterns to discover the sensor locations, and then prewarp the image to accurately fit the physical features of the projection surface. This technique can be expanded to automatically stitch multiple projectors, calibrate onto non-planar surfaces for object decoration, and provide a method for simple geometry acquisition.
