The brain activity is most commonly measured non-invasively via standard electroencephalography (EEG), i.e., with electrodes placed on the surface of the scalp. In this article, we evaluate a BCI system based on steady-state visual evoked potentials (SSVEPs) in real world conditions. Although the performance of this type of BCI has already been proved by several research groups with healthy users in laboratory settings assisted by scientific researchers, there are still many difficulties in changing from demonstration systems to practical BCIs. The Bremen-BCI was evaluated in this case study with 37 naive subjects (without any SSVEP-BCI experience), including 8 handicapped users, at the international rehabilitation fair RehaCare2008. In spite of unsuitable environment conditions on the fair, the spelling tasks were successfully completed by 32 participants with a mean accuracy of over 92% and an average information transfer rate (ITR) of 22.6[bits/min]. No significant dependency of the physical disability of participants on the ITR could be observed.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116357297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neurological disorders such as stroke affect multiple joints simultaneously with stereotypical patterns of arm deformity involving shoulder, elbow, wrist and fingers. Some of the symptoms are manifested in passive movement while others in voluntary movement. However, there is a lack of systematic methods to evaluate multi-joint and multi-DOF (degrees of freedom) neuro-mechanical changes during both passive and active movements, especially for complex systems with three or more joints/DOFs involved. The purposes of this study was to develop a systematic method to characterize dynamics and control of the shoulder, elbow and wrist of the human arm individually and simultaneously, including the interactions across the three joints, during both passive and active movements. A new method was developed to decompose the complex system into manageable single-joint level for more reliable characterizations. The method was applied to clinical studies on multi-joint changes associated with hypertonic arm with impaired motor control post stroke during both passive and active movements. In general, the decomposition method can be used for even more complex systems, making intractable system dynamics of three or more joints and DOFs manageable.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124150227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small size actuator or portable actuator has many possible applications in medicine and industry. In the past, motors have been widely used to create motion in large-area tactile displays.

However, there are also challenges using SMA as actuator. The nonlinear hysteresis properties of the SMA cause difficulties during the control of the display. Our design is an 8x8 display consists of 64 SMA springs to create motion for 64 pin display. Each of the pin display takes approximately 0.4 seconds to response to the input.

In particular, we considered a tracking task to a visual target whose frame of reference is rotated with respect to a body-fixed frame in a time-varying manner. We investigated it by means of a wrist robot coupled with a virtual reality system: kinesthetic and visual disturbances were applied during a tracking task, in a unimodal and bimodal manner, and we observed the performance. Tracking involved two degrees of freedom and the kinesthetic disturbance was applied by the robot through the third degree of freedom. Visual disturbance was provided by rotating the visual feedback. The results suggest that the combination of a suitable proprioceptive feedback with the kinematic redundancy of the HCI system might be a rather general principle for improving the efficiency of HCI systems.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"169 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131747282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method processed acceleration and angular velocity measured by a shank-mounted inertia measurement unit and output stride-by-stride walking speed and slope information in real time. Instead of estimating gait parameters indirectly, this method integrated the transformed accelerations to calculate stride length, walking speed and slope in each gait cycle. The main challenge is to determine the integration initial values at the beginning of each gait cycle. By taking the advantage of inverted pendulum model of walking, we identified a appropriate way to segment a walking sequence into gait cycles such that all of the required initial values were available. Experimental results demonstrated that the proposed method could accurately estimate the walking speeds under different walking conditions. However, the method estimated the slope with a lower accuracy.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132091976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects and roles of active / passive force feedback for rehabilitative effects have not been clarified yet. Since a few years ago, we have developed an active / passive switchable rehabilitation system for upper limbs (Hybrid-PLEMO) to address these questions. In this paper, we describe force-feedback mechanism of the Hybrid-PLEMO. Then, we suggest a new approach to facilitate a human reaching motion with our system.
