In this paper, we propose the Perceptual Shape Decomposition (PSD) to detect fingers for a Kinect-based hand gesture recognition system. The PSD is formulated as a discrete optimization problem by removing all negative minima with minimum cost. Experiments show that our PSD is perceptually relevant and robust against distortion and hand variations, and thus improves the recognition system perfo...

This study proposes a new pallet recognition system using Kinect camera. Depth image of Kinect camera is produced from the infrared ray data of random dot type. This system was applied to an automated guided vehicle(AGV) to recognize the pallet in various conditions. A modularized hardware and software of the pallet recognition system was developed. The performance of the developed pallet recog...

We propose a novel low-cost method for quantitative assessment of upper extremity workspace envelope using Microsoft Kinect camera. In clinical environment there are currently no practical and cost-effective methods available to provide arm-function evaluation in three-dimensional space. In this paper we examine the accuracy of the proposed technique for workspace estimation using Kinect in com...

Motion sensing devices like Microsoft’s Kinect offer an alternative to traditional computer input devices like keyboards and mouses. Graph databases can naturally make use of gesture control as traversing graphs can easily be described by swiping or pointing gestures. In our demo we traverse the Internet Movie Database (IMDB) using a Kinect interface with the control logic in our data stream en...

OBJECTIVES Existing methods for practically evaluating musculoskeletal exposures such as posture and repetition in workplace settings have limitations. We aimed to automate the estimation of parameters in the revised United States National Institute for Occupational Safety and Health (NIOSH) lifting equation, a standard manual observational tool used to evaluate back injury risk related to lift...

Several approaches to calibration of the Kinect as a range sensor have been presented in the past. Those approaches do not take into account a possible influence of thermal and environmental conditions. This paper shows that variations of the temperature and air draft have a notable influence on Kinect’s images and range measurements. Based on these findings, practical rules are stated to reduc...

The Microsoft Kinect is a popular and versatile input device for musical interfaces. However, using the Kinect for such interfaces requires not only significant programming experience, but also the use of complex geometry or machine learning techniques to translate joint positions into higher level gestures. We created the Kinect Instrument Builder (KIB) to address these difficulties by structu...

The motivation for our project is to provide choreographers with a new software and hardware tool for composing and recording multi-dancer choreographies from a single dancer. We use a Microsoft Kinect camera/sensor to record 3D point-cloud sequences of a dancer in motion. In a 3D point-cloud, or sequence, a grid of 640x480 infrared dots are projected by the Kinect sensor, and a sensor records ...

We propose to combine the Kinect and the Integral-Imaging technologies for the implementation of Integral Display. The Kinect device permits the determination, in real time, of (x,y,z) position of the observer relative to the monitor. Due to the active condition of its IR technology, the Kinect provides the observer position even in dark environments. On the other hand, SPOC 2.0 algorithm permi...

The Kinect sensor gives computer eyes. It can capture 3D coordinates of human body joints. This provides a convenient way to track human body movement. This paper proposes an on-line physical training system using 3D sensors (Kinect) so that the exercise instructor and the athletes who are not in the same location can collaborate and fulfil training tasks remotely. The system captures the motio...
