Introduction/Background Recent clinical studies have shown that electroencephalogram- (EEG) based neurofeedback training promotes functional recovery of finger movements in poststroke patients (Pichiorri F et al., Ann Neurol. 2015). However, impairment of shoulder elevation in poststroke severe chronic hemiplegia is a debilitating condition with no evidence-based, accessible treatment. To verify motor recovery evidence of neurofeedback training with our shoulder exoskeleton robot, this study reports upper extremity section of Fugl-Meyer assessment (FMA-UE) associated with the evaluation of up-conditioning of contralesional corticospinal pathways. Material and method Eight poststroke patients with severe hemiplegia in the chronic stage were recruited (FMA-UE score = 16.8 ± 4.4). Patients engaged in 1 hour daily training for 7 consecutive days ( Fig. 1 ), and clinical and neurophysiological measurements were performed 1 day before and after the intervention. FMA-UE was used for the primary outcome measure. A 128-channel whole-head EEG was used to assess the hemispheric lateralization of event-related desynchronization (ERD). Single-pulse transcranial magnetic stimulation (TMS) was applied to the contralesional primary motor cortex to assess the corticospinal excitability in 6 tested patients. Results All participants finished the intervention without adverse events. FMA-UE was significantly improved after the intervention (paired t -test, P < 0.01). All patients demonstrated improved FMA-UE (mean change = 6.6 ± 3.2) and 6 of 8 patients exceeded the minimal clinically important difference that is set to 5. From the group analysis of hemispheric lateralization of ERD, the contralesional ERD became stronger after interventions (Wilcoxon signed-rank test, P < 0.01). Motor evoked potentials became more apparent after interventions in 3 of the 6 tested patients. Conclusion The results from this study demonstrated targeted up-conditioning of contralesional corticospinal path

This paper presents an economic real-time system for tracking a fast moving object using adjacent inexpensive multiple web cameras. Our experimental system includes three cameras that integrated into three client computers, and an acquisition sever computer that receives information from the clients and estimates the object speed in real-time. In this system, the three client computers play the role of monitor stations that detect the object, calculate the object position and capture the moment of a successful detection. From information of clients, the server estimates the relative positions of the object in each detection event to calculate the instantaneous velocities of the object. Finally, the speed of the object is determined by its average velocity in its all trajectory. The experimental results perform an accurate measurement on the setup environment.

Human-robot Interaction is most important function for social robot systems. Android robot systems, which have human-like appearance, are used for interaction with humans because they have the merit of showing their emotions by similar way to humans. Lots of these robot systems are developed and verified their efficiency and performance by analyzing the experimental results from questionnaire method. However, the results from questionnaire method can be different from many conditions. In this paper, we analyze the difference of experimental results from questionnaire method by comparing three groups: the first group gains benefits by competition, the second group gains benefits without competition, and the last group does not gain anything. For these experiments, android head system EveR-4 H33, which has 33 motors inside of head to show its facial expressions, is used. © 2012 Springer-Verlag.

There are many theories about basic emotions, and we do not know which emotions are appropriate to use. Also, faces of robots are designed differently and require different ways to embody emotional expressions. Therefore, in this paper we address the appropriate emotions for facial expressions of EveR-4 H33, which is controlled by thirty-three motors for head system. EveR-4 H33 displays her facial expressions for certain emotions selected from typical basic emotion theories. Then, audiences at an exhibition evaluate her facial expressions, by enjoying a game of emotional correction. We analyze the results of the game, and decide appropriate emotions for EveR-4 H33. © 2012 IEEE.

The detection of moving objects for the surveillance and monitoring has been studied in the computer vision community for many years. Traditionally, the studies assume the use of a stationary camera. When using a 3D point cloud, research is restricted to the fixed laser scanner because of the slow data acquisition time. In this paper, we propose a method for detecting moving objects based on a freely moving sensor that provides two-dimensional-three-dimensional(2D-3D) fused data. Our method is a frame-differencing, which compares two consecutive frames combining visual features and a 3D point cloud. The RANSAC and ICP algorithms are applied for more accurate results. The moving objects can be separated in the 3D point cloud by adopting RANSAC outliers.

This paper analyzes emotional expressions of an android head system according to gender and age. We use an EveR-4 H33 controlled by thirty-three motors for facial expression. EveR-4 H33 is a head system for an android face consists of three layers: a mechanical layer, an inner cover layer and an outer cover layer. Facial expressions of robots are different from the purposes of robots. In addition, feeling of emotional expressions is also different from humans depending on age, gender, etc. Therefore, we find the appropriate uses of EveR-4 H33 in this paper. EveR-4 H33 shows her facial expressions about some emotions. Then, audiences of exhibition evaluate her facial expressions by enjoying a game of emotional correction. We analyze the results of the game according to gender and age, and decide appropriate uses of EveR-4 H33.

This paper proposes a strategy for grasp and manipulation of unknown objects. In order to derive force relations of fingers, the groped shape of soft fingers is introduced. The groped shape is not equal to the real object shape, but is tightly related to the force equilibrium of fingers. By considering contact forces of the groped shape, a simple control parameters can be derived. The manipulation of an object is easily accomplished by embedding the concept of virtual centroid into the grasp control to redistribute internal forces. With these concepts, an object can be easily translated, rotated, and manipulated by relocating fingers. The proposed method is verified with experiments.
