Physical therapy has been used successfully to slow the effects of this degenerative disease. Patients, however, do not want to do these exercises due to the fact they are boring and repetitive. In this paper, we introduce the first steps in creating a virtual environment using a CAVE System for the physical therapy sessions where the user will be engaged and motived to complete the exercises prescribed by his or her doctor.","PeriodicalId":91811,"journal":{"name":"The ...

Electrical activity in the user's target muscular region, which exceeds a specified threshold, translates into actuation of the designated primary grasp for the commercial product, MechaTE robotic hand. The interface was successful in a real-time demonstration where a user was able to catch a billiard ball moving across a pool table. This prototype provides the foundation for a more advanced HCI, with dexterous, multi-grasp capabilities. Future work aims to create a novel non-invasive brain computer interface (BCI) which can be used to restore partial functionality to transradial amputees.","PeriodicalId":91811,"journal":{"name":"The ...

The framework uses the Student-t pdf (a) as an observation model of a Hidden Markov Model to represent a topological map (b) to represent the robot motion model. The map and the motion model are calculated in an expectation maximization (EM) framework. We show that the estimator converges at linear time and that the provided accuracy is higher compared to using a conventional Gaussian mixture pdf, due to higher noise resiliency, as well as compared to using a fixed robot motion model. The task is assisted by unsupervised landmark definition through the EM-based clustering of the observations and by scene representation using the complex Zernike moments, which provide rich rotation-invariant information. The validity of the method has been verified experimentally using the input from an omnidirectional camera.","PeriodicalId":91811,"journal":{"name":"The ...

They can be hidden behind materials such as wood, wool or plastics without limiting their functionality, making them ideal for application in Ambient Intelligence (AmI) scenarios. Most gesture recognition frameworks are targeted towards classical input devices and interpret two-dimensional data. In this work, we present a concept for adapting classical gesture recognition methods for capacitive input devices by realizing an extension of the feature set to three dimensional input data. This allows more robust gesture recognition for free-space interaction and training specific to capacitive input devices. We have implemented this concept in a prototypical setup and tested the device in various Ambient Intelligence scenarios, ranging from manipulating home appliances to controlling multimedia applications.","PeriodicalId":91811,"journal":{"name":"The ...

COPD patients require lung function examinations and perform breathing exercises on a regular basis in order to manage and be more aware of their health status. In this paper, we designed and developed a mobile-phone based system for lung function diagnosis, called mCOPD. Besides enabling accurate COPD examinations at home, the mCOPD system also offers a video-game based guidance system for breathing exercises. We evaluated mCOPD in controlled and uncontrolled environments with 40 subjects. The experimental results show that our system is a promising tool for remote medical treatment of COPD.","PeriodicalId":91811,"journal":{"name":"The ...

During the design process of a collaborative project, we studied four different types of sketches with seniors. Through these sketches we discussed ideas around tourism, human values and interaction issues with special regards to the context of aging. The design process, insights and results from studies with fifty senior travelers showed that, design sketching has different impacts based on the sketch type. This further impacts the nature of data gathered from multi-faceted design space of AAL for future products. As visual and corporate design of AAL products are becoming increasingly important for the adoption of such products, the detailed understanding of related design techniques such as sketching is equally important for the development of such products.","PeriodicalId":91811,"journal":{"name":"The ...

Existing gait-monitoring devices are not routinely used in clinical practice since they lack accuracy, ease-of-use, and unobtrusiveness. We present a novel breakthrough Kinect-based robotic system to accurately monitor the human gait during normal daily-life activities. Our system combines many interesting features: it has unlimited capturing volume, it is low cost, and does not require fiducial markers on the person. We present an extensive study of its accuracy in computing fall-prediction parameters when compared to the Vicon motion-capture system.","PeriodicalId":91811,"journal":{"name":"The ...

A KUKA youBot ® mobile manipulator was sensorized using 7 FlexiForce® piezo-resistive sensors, attached to the surface of the manipulator arm. ROS transfers frame and Kinematics libraries transferred interaction pushing forces measured by the sensors to velocity commands to the robot. These results transformations were verified using a derived Denavit-Hartenberg table. Resulting robot movement is always parallel to the axis of detected forces, regardless of orientation of the sensors relative to the mobile manipulator's base, or the number of sensors detecting forces. Verification of this behavior was conducted during two separate experiments.

In this paper, we will describe the procedures followed for the successful software and hardware implementation and demonstration of an obstacle avoidance path planning algorithm thus augmenting the existing modalities. The algorithm uses a vision system to identify the location and size of an obstacle and generate the robot path to reach a desired goal while avoiding the obstacle.
