Based on the statistical data of the most common types of disabilities in Spain and other industrialized countries, the different tasks that the device must be able to perform have been determined. In this study, different robots for rehabilitation and assistance previously introduced have been reviewed. This survey is focused on those robots that assist with gait, balance and standing up. The structure of the ROAD robot presents various advantages over these robots, we discuss some of them. The performance of the proposed architecture is analyzed when it performs the sit to stand activity.

In this approach multiple threads (e.g. haptics thread, graphics thread, collision detection thread, etc.) run concurrently and therefore we developed a synchronization mechanism for data exchange. We describe in detail the elements of the developed software.

The focus of this work is, to provide methods to generate haptic feedback which is purely based on previously recorded quantities. No models are employed for the haptic properties of the scene content. According to task 4.4 the advances in the development of a multi-body dynamic hand model are described. A demonstrator of object manipulation has been developed and a realistic human hand model has been defined. The human hand model has been developed in order to realistically characterize and model hand postures during object grasping. Concepts for haptic modulation are presented as proposed in task 4.5. A terminology is established which distinguishes between the pure manipulation of haptic signals by data processing techniques and the augmentation of the raw haptic feedback by signals based on additional information. Formulas are proposed how to merge two haptic signals from two different sources into one signal which is provided to the user. In addition, some applications for these concepts are given that can be used to conduct according experiments. Complying with task 4.6 a method is described that integrates haptic cues into contact space D4.2.1 Systems and Methods of Interaction, Report + Demonstrators This page is left blank intentionally.

The shape of the scaling function is simply related to the shape of the topological cross sections. A statistical study of the models is made and the thermodynamic limit is investigated. An attempt to relate the impact parameter picture of high energy elastic hadron scattering and the scaling phenomenon is presented. Special realistic cases are explored in detail.
