In this thesis we propose a solution to how a system can find and track people, as well as recognizing their gestures, in a 360◦ field of view using consumer grade products. We describe a system connecting multiple depth cameras in an array and have them operate as a single camera controlled by a single computer. Using a single camera providing features such as detection, tracking and recognizi...

PURPOSE OF THE STUDY Falls are a major problem for the elderly people leading to injury, disability, and even death. An unobtrusive, in-home sensor system that continuously monitors older adults for fall risk and detects falls could revolutionize fall prevention and care. DESIGN AND METHODS A fall risk and detection system was developed and installed in the apartments of 19 older adults at a ...

The Microsoft Kinect sensor has gained attention as a tool for gait analysis for several years. Despite the many advantages the sensor provides, however, the lack of a native capability to extract joints from the side view of a human body still limits the adoption of the device to a number of relevant applications. This paper presents an algorithm to locate and estimate the trajectories of up t...

[Purpose] The purpose of this study was to investigate the effects of training using video games played on the Xbox Kinect on the muscle strength, muscle tone, and activities of daily living of post-stroke patients. [Subjects] Fourteen stroke patients were recruited. They were randomly allocated into two groups; the experimental group (n=7) and the control group (n=7). [Methods] The experimenta...

In this paper we present a novel Gaussian Process (GP) prior model-based sensor fusion approach to dealing with position uncertainty and lag in a system composed of an external position sensing device (Kinect) and inertial sensors embedded in a mobile device for user performance improvement. To test the approach, we conducted two experiments: (1) GPs sensor fusion simulation. Experimental resul...

The purpose of this study was to test the implementation of a fall detection and "rewind" privacy-protecting technique using the Microsoft® Kinect™ to not only detect but prevent falls from occurring in hospitalized patients. Kinect sensors were placed in six hospital rooms in a step-down unit and data were continuously logged. Prior to implementation with patients, three researchers performed ...

The emerging topic of cross-source point cloud (CSPC) registration has attracted increasing attention with the fast development background 3D sensor technologies. Different from conventional same-source clouds that focus on data same kind (e.g., Kinect), CSPCs come different kinds sensors Kinect and LiDAR). CSPC generalizes requirement acquisition to sources, which leads generalized application...

The Kinect v2 is a RGB-D sensor manufactured as a gesture interaction tool for the entertainment console XBOX One. In this thesis we will use it to perform 3D reconstruction and investigate its ability to measure depth. In order to sense both color and depth the Kinect v2 has two cameras: one RGB camera and one infrared camera used to produce depth and near infrared images. These cameras need t...

BACKGROUND The use of exergaming is a potential alternative to traditional methods of balance training, which can be repetitive and somewhat monotonous. The purpose of this study was to assess the effects of exergaming using XBOX Kinect™ versus traditional gym-based exercise with no virtual stimuli (TGB) on postural control, technology acceptance, flow experience and exercise intensity, in youn...

Results of using an RGB-D camera (Kinect sensor) and a stereo camera, separately, in order to determine the 3D real position characteristic points predetermined object scene are presented. KAZE algorithm was used make recognition, that exploits nonlinear scale space through diffusion filtering; coordinates centroid were calculated employing calibration information depth parameter provided by Ki...
