BACKGROUND Xbox Kinect has been proposed as an exercise intervention in cystic fibrosis (CF), but its potential has not been compared with standard training modalities. METHODS Using a crossover design, subjects were randomized to 2 intervention groups: Xbox Kinect and a traditional stationary cycle. Heart rate, SpO2, dyspnea, and fatigue were measured. Subject satisfaction was tested. RESU...

Kinect skeleton tracker is able to achieve considerable human body tracking performance in convenient and a low-cost manner. However, The tracker often captures unnatural human poses such as discontinuous and vibrated motions when self-occlusions occur. A majority of approaches tackle this problem by using multiple Kinect sensors in a workspace. Combination of the measurements from different se...

With this project, we aim to explore solutions for the reconstruction of real objects by analyzing the state-of-the-art algorithm Kinect Fusion that allows real-time reconstruction and rendering of a real world scene and one implementation of it. We use the point clouds obtained from Kinect Fusion and the PCL libraries to create a 3D scanner application and show the results of our work. This do...

It is difficult to obtain timely feedback from traditional video-based motion analysis during a regular sports training session due to the demands of camera placement and data processing. However, advanced devices such as the Kinect may have practical use in this regard. The present study examined the usefulness of a Kinect device in evaluating pommel horse performance in men’s artistic gymnast...

Kinect and Leap Motion sensors are commonly used for tracking applications today. However, both sensors have failure modes in particular tracking scenarios. The Kinect sensor is very sensitive to the orientation of the user with respect to the sensor and is susceptible to occlusions. The Leap Motion senor has a limited range and field of view, but is far more accurate than the Kinect. In this p...

This paper presents the development of a level control system using 3D machine vision techniques based on a single leveldetector sensor (Kinect), in an arrangement of three tanks. Using image processing algorithms, each one of the tanks is classified within the video sequence as well as each one of the depth measurements is averaged regarding the cross sectional area of the surface of the tanks...

The stochastic error characteristics of the Kinect sensing device are presented for each axis direction. Depth (z) directional error is measured using a flat surface, and horizontal (x) and vertical (y) errors are measured using a novel 3D checkerboard. Results show that the stochastic nature of the Kinect measurement error is affected mostly by the depth at which the object being sensed is loc...

For years, the games, except their entertaining aspect, have acquired an educational character. In recent decades, games have evolved and we were led up to the electronic games, and thus to Kinect. Already, many institutions worldwide use the Kinect to the learning process. So, through this article we take a step further and we suggest the use of Kinect as a learning auxiliary tool for children...

In this paper we present the evaluation results for estimating the area of detection as well as the rotation accuracy of two versions of the face tracking system of the Microsoft Kinect sensor. The tested sensors are the Kinect for Windows V1 and V2 sensors in the use with the respective Software Development Kit. The tests were performed using an artificial head which was moved along a grid. Th...

This paper proposes interaction techniques to use Microsoft Kinect in Virtual Reality (VR) applications. Most of the proposed techniques are used in a similar fashion with devices other than Microsoft Kinect, that will allow a user to select objects in a virtual scene and navigate throughout that scene. Kinect was chosen because it is low cost, easily portable and does not require the user to h...
