“…Although it is difficult to make an accurate comparison, because the first [15], uses a diffe rent device to track movement, and the second [16], is oriented to complex pose comparison in 3D motion data. We cannot compare results with other systems that use Kinect [8][9][10][11][12][13] because they do not provide perfonnance results. During the tests we also established a threshold value for posture recognition.…”

“…Finally, with the aim of fa cilitating even more the interaction of users appears another trend that advocates the use of Kinect, a motion capture device that tracks user movements without any physical contact. Among the proposals that fo llow that trend we can distinguish those 978-1-4673-5801-9/13/$26.00 ©2013 IEEE 444 that use Kinect Xbox version [8][9][10] and those that use Kinect for Windows, a version that was launched in February 2012. In this last case, the proposals that can be fo und are mainly commercial products such as [1 1-13] which do not show many technical details concerning their internal behavior and are oriented to specific pathologies.…”

The goal of this paper is to show the main fe atures of KiReS, a telerehabilitation system based on Kinect for Windows, that offers, for both, users and physiotherapists some specific elements that make it more fr iendly to them. From the point of view of users, they can see in two 3D avatars how an exercise must be executed and how they execute it respectively. This fe ature can help them improve exercises performance. Moreover during the rehabilitation session they will always see an informative list that shows the exercises to be done in the session. From the point of view of physiotherapists the system allows them on the one hand, to define customized rehabilitation therapies. That can be done by defining different exercises that combine pre-defined movements. Moreover, they can add tests oriented to specific illnesses so that users themselves evaluate their physical state. On the other hand, they can create new exercises just performing those exercises in fr ont of the system and recording them. Those fe atures, not fu lly supported by already existing telerehabilitation systems, provide an added value that is well valued by both groups. Moreover, a prototype of KiReS is in operation, and allowed us to test its suitability fr om the point of view of real time performance as well as fr om the point of view of usability.

Microsoft Kinect, a low-cost motion sensing device, enables users to interact with computers or game consoles naturally through gestures and spoken commands without any other peripheral equipment. As such, it has commanded intense interests in research and development on the Kinect technology. In this paper, we present, a comprehensive survey on Kinect applications, and the latest research and development on motion recognition using data captured by the Kinect sensor. On the applications front, we review the applications of the Kinect technology in a variety of areas, including healthcare, education and performing arts, robotics, sign language recognition, retail services, workplace safety training, as well as 3D reconstructions. On the technology front, we provide an overview of the main features of both versions of the Kinect sensor together with the depth sensing technologies used, and review literatures on human motion recognition techniques used in Kinect applications. We provide a classi¯cation of motion recognition techniques to highlight the di®erent approaches used in human motion recognition. Furthermore, we compile a list of publicly available Kinect datasets. These datasets are valuable resources for researchers to investigate better methods for human motion recognition and lowerlevel computer vision tasks such as segmentation, object detection and human pose estimation.

Skyfarer is a mixed reality shoulder exercise game developed for prevention and treatment of shoulder pain for individuals aging with spinal cord injury. We are adapting a shoulder exercise protocol that has been evaluated in a randomized clinical trial [Mulroy et al. 2011]. This demonstration will showcase a secondgeneration integrated exercise hardware and software system. The system consists of an adjustable metal rig outfitted with GameTrak sensors that are attached to interchangeable Thera-Bands and free weights. The rig can accommodate individuals with various types of manual wheelchairs and can be adjusted for arm length. The GameTrak sensors provide three-dimensional movement data to the calibration and exercise software application that was developed in Unity Engine 3.5. Figure 1. Skyfarer 0.5a (left and bottom right) was evaluated in real-time in a biomechanical study (top right) Skyfarer has emerged after iterating numerous prototypes that incorporated individual elements of a shoulder exercise protocol using a first-generation metal rig [Gotsis et al. 2012]. Skyfarer requires calibration of the game to the physical dimensions and muscle strength of individual players. Player profiles can be stored and the number of required repetitions per exercise can be manually adjusted before playing.Figure 3 Resistance-training exercises in Skyfarer 0.5aSkyfarer 0.5a incorporates the following parts of the exercise protocol: external rotation, rowing, diagonal pull-down and vertical lift exercises. This version has been evaluated in a biomechanical study conducted at Rancho Los Amigos National Rehabilitation Center. The virtual environment immerses players _____________________________ * email: mgotsis@cinema.usc.edu into an adventure inspired by Pre-Colombian mythology inspired by the landscapes of South America. With each exercise, players prepare, propel and lift their vessel into water or air, collecting energy that can be used during breaks between exercise sets. Skyfarer 0.5b includes Microsoft Kinect as input for free-form movement segments of the game, such as drawing and improved calibration, animation and movement cuing. Figure 2. Each movement is first shown to the player and then calibrated for their abilities and body dimensions before playing Acknowledgements
