Roland Piquepaille reports that "An international team of European researchers has implanted an artificial cerebellum - the portion of the brain that controls motor functions - inside a robotic system. This EU-funded project is dubbed SENSOPAC, an acronym for "SENSOrimotor structuring of perception and action for emerging cognition". One of the goals of this project is to design robots able to interact with humans in a natural way. This project, which should be completed at the end of 2009, also wants to produce robots which would act as home-helpers for disabled people, such as persons affected by neurological disorders, such as Parkinson's disease."

C/net reports that BT is developing services that will enable users of virtual worlds to call or text out to their colleagues and friends in the real world. "To test the technology it has built a private island in Second Life, which it has dubbed Area 21 - a play on the ultra-secret Area 51 and BT's 21CN network technology, which is being used in the service"

Developing a Telepresence Robot for Interpersonal Communication with the Elderly in a Home Environment.

Telemed J E Health. 2007 Aug;13(4):407-424

Authors: Tsai TC, Hsu YL, Ma AI, King T, Wu CH

"Telepresence" is an interesting field that includes virtual reality implementations with human-system interfaces, communication technologies, and robotics. This paper describes the development of a telepresence robot called Telepresence Robot for Interpersonal Communication (TRIC) for the purpose of interpersonal communication with the elderly in a home environment. The main aim behind TRIC's development is to allow elderly populations to remain in their home environments, while loved ones and caregivers are able to maintain a higher level of communication and monitoring than via traditional methods. TRIC aims to be a low-cost, lightweight robot, which can be easily implemented in the home environment. Under this goal, decisions on the design elements included are discussed. In particular, the implementation of key autonomous behaviors in TRIC to increase the user's capability of projection of self and operation of the telepresence robot, in addition to increasing the interactive capability of the participant as a dialogist are emphasized. The technical development and integration of the modules in TRIC, as well as human factors considerations are then described. Preliminary functional tests show that new users were able to effectively navigate TRIC and easily locate visual targets. Finally the future developments of TRIC, especially the possibility of using TRIC for home tele-health monitoring and tele-homecare visits are discussed.

Visuo-motor learning with combination of different rates of motor imagery and physical practice.

Sports psychology suggests that mental rehearsal facilitates physical practice in athletes and clinical rehabilitation attempts to use mental rehearsal to restore motor function in hemiplegic patients. Our aim was to examine whether mental rehearsal is equivalent to physical learning, and to determine the optimal proportions of real execution and rehearsal. Subjects were asked to grasp an object and insert it into an adapted slot. One group (G0) practiced the task only by physical execution (240 trials); three groups imagined performing the task in different rates of trials (25%, G25; 50%, G50; 75%, G75), and physically executed movements for the remaining trials; a fourth, control group imagined a visual rotation task in 75% of the trials and then performed the same motor task as the others groups. Movement time (MT) was compared for the first and last physical trials, together with other key trials, across groups. All groups learned, suggesting that mental rehearsal is equivalent to physical motor learning. More importantly, when subjects rehearsed the task for large numbers of trials (G50 and G75), the MT of the first executed trial was significantly shorter than the first executed trial in the physical group (G0), indicating that mental practice is better than no practice at all. Comparison of the first executed trial in G25, G50 and G75 with the corresponding trials in G0 (61, 121 and 181 trials), showed equivalence between mental and physical practice. At the end of training, the performance was much better with high rates of mental practice (G50/G75) compared to physical practice alone (G0), especially when the task was difficult. These findings confirm that mental rehearsal can be beneficial for motor learning and suggest that imagery might be used to supplement or partly replace physical practice in clinical rehabilitation.

A new mechanical arm trainer to intensify the upper limb rehabilitation of severely affected patients after stroke: design, concept and first case series.

Description and case series on a new mechanical arm trainer with three degrees of freedom (DoF), the REHA-SLIDE (RS), for stroke rehabilitation are presented. Similar to a rolling pin, it consists of two handles at either side of a connecting rod, the handles are bilaterally moved forward and backward, sideways, and rotated, the base plate is inclinable. A computer mouse attached to the rod enables playing games offering computer-biofeedback. Two patients, 6 and 5 weeks after a first-time supratentorial stroke, suffering from a flaccid non-functional upper extremity have been studied. Interventions performed were additional 30 min of RS-training every workday for 6 weeks; one session included 400 repetitions evenly distributed between the forward backward movement and drawing a circle clock- and counter clockwise. Afterwards the patients could play games. Upper extremity portion of the Fugl-Meyer Motor Assessment Score (FM, 0-66), and muscle strength by a Medical Research Council (MRC) sum score (0-45), the FM assessment was blinded. In the 2 patients, the FM (0-66) improved from 7 to 37, and from 17 to 43, their initial (terminal) MRC sum scores were 6 (36) and 13 (31). With the REHA-Slide (RS), severely affected patients practiced a bilateral 3 DoF movement. No conclusions can be drawn so far and a controlled clinical study must be the next step.
