Description
Motion capture using cost-effective sensing technology is challenging and the huge success of Microsoft Kinect has been attracting researchers to uncover the potential of using this technology into computer vision applications. In this thesis, an upper-body motion analysis in a home-based system for stroke rehabilitation using novel RGB-D camera - Kinect is presented. We address this problem by first conducting a systematic analysis of the usability of Kinect for motion analysis in stroke rehabilitation. Then a hybrid upper body tracking approach is proposed which combines off-the-shelf skeleton tracking with a novel depth-fused mean shift tracking method. We proposed several kinematic features reliably extracted from the proposed inexpensive and portable motion capture system and classifiers that correlate torso movement to clinical measures of unimpaired and impaired. Experiment results show that the proposed sensing and analysis works reliably on measuring torso movement quality and is promising for end-point tracking. The system is currently being deployed for large-scale evaluations.

Description
Stroke is a leading cause of disability with varying effects across stroke survivors necessitating comprehensive approaches to rehabilitation. Interactive neurorehabilitation (INR) systems represent promising technological solutions that can provide an array of sensing, feedback and analysis tools which hold the potential to maximize clinical therapy as well as extend therapy to the home. Currently, there are a variety of approaches to INR design, which coupled with minimal large-scale clinical data, has led to a lack of cohesion in INR design. INR design presents an inherently complex space as these systems have multiple users including stroke survivors, therapists and designers, each with their own user experience needs. This dissertation proposes that comprehensive INR design, which can address this complex user space, requires and benefits from the application of interdisciplinary research that spans motor learning and interactive learning. A methodology for integrated and iterative design approaches to INR task experience, assessment, hardware, software and interactive training protocol design is proposed within the comprehensive example of design and implementation of a mixed reality rehabilitation system for minimally supervised environments. This system was tested with eight stroke survivors who showed promising results in both functional and movement quality improvement. The results of testing the system with stroke survivors as well as observing user experiences will be presented along with suggested improvements to the proposed design methodology. This integrative design methodology is proposed to have benefit for not only comprehensive INR design but also complex interactive system design in general.

Description
In order to regain functional use of affected limbs, stroke patients must undergo intense, repetitive, and sustained exercises. For this reason, it is a common occurrence for the recovery of stroke patients to suffer as a result of mental fatigue and boredom. For this reason, serious games aimed at reproducing the movements patients practice during rehabilitation sessions, present a promising solution to mitigating patient psychological exhaustion. This paper presents a system developed at the Center for Cognitive Ubiquitous Computing (CubiC) at Arizona State University which provides a platform for the development of serious games for stroke rehabilitation. The system consists of a network of nodes called Smart Cubes based on the Raspberry Pi (model B) computer which have an array of sensors and actuators as well as communication modules that are used in-game. The Smart Cubes are modular, taking advantage of the Raspberry Pi's General Purpose Input/Output header, and can be augmented with additional sensors or actuators in response to the desires of game developers and stroke rehabilitation therapists. Smart Cubes present advantages over traditional exercises such as having the capacity to provide many different forms of feedback and allowing for dynamically adapting games. Smart Cubes also present advantages over modern serious gaming platforms in the form of their modularity, flexibility resulting from their wireless network topology, and their independence of a monitor. Our contribution is a prototype of a Smart Cube network, a programmable computing platform, and a software framework specifically designed for the creation of serious games for stroke rehabilitation.
