    Future brain controlled technology

    I thought of starting a thread where debate is not necessary and discussion is welcome, e.g. contribution of thoughts on this matter or bring up new stuff we haven't heard about.

    Here's an article on: A Brain controlled "ironman" suit

    World Cup robo-suit team dismiss underwhelmed critics
    It's about the paraplegic man who kicked off the world cup in a robo-suit

    It is done like this:
    Brain Computer Interfaces…Controlling With Your thoughts

    BCI, or what is commonly known as Brain-Computer Interface is an emerging group of technologies which can also be presented as brain-machine interfaces (BMI), or mind-machine interfaces (MMI). In the recently published book of research, Introduction to Neural Engineering for Motor Rehabilitation (2013) by Dario Farina, Winnie Jensen and Metin Akay, the summary on the chapter covering BCI’s provides an excellent definition of BCI’s and the current applications they are being used in.

    “A BCI monitors the user’s brain activity, extracts specific features from the brain signals that reflect the intent of the subject, and translates them into action. BCI Technology offers a natural way to augment human capabilities by providing a new interaction link with the outside world and, thus it is particularly relevant as an aid for patients with severe neuromuscular disabilities.” (Millan, p. 237).

    Seeing the little movements of the person controlling the robots is pretty intriguing.

    Are these programmed by monitoring a person think, for example, "Move Up", recording the brain activity, then programming the robot to respond to that sort of activity?

      Hi, I understand it sofar as: an interface is programmed to translate real time EEG alike information of which they suspect (my guess) it's representing thought of movement.

      The world cup intro was not received well coz it didn't show much, but this part of controlling a robo-suit is quite challenging.

      What is being achieved already is this (you might have seen it)

        Here's an older video of a "robo-suit" used by a paraplegic woman

        Design and evaluation of Mina: A robotic orthosis for paraplegics

        Mobility options for persons suffering from paraplegia or paraparesis are limited to mainly wheeled devices. There are significant health, psychological, and social consequences related to being confined to a wheelchair. We present the Mina, a robotic orthosis for assisting mobility, which offers a legged mobility option for these persons. Mina is an overground robotic device that is worn on the back and around the legs to provide mobility assistance for people suffering from paraplegia or paraparesis. Mina uses compliant actuation to power the hip and knee joints. For paralyzed users, balance is provided with the assistance of forearm crutches. This paper presents the evaluation of Mina with two paraplegics (SCI ASIA-A). We confirmed that with a few hours of training and practice, Mina is currently able to provide paraplegics walking mobility at speeds of up to 0.20 m/s. We further confirmed that using Mina is not physically taxing and requires little cognitive effort, allowing the user to converse and maintain eye contact while walking.
        This technology used for the benefit of people with disability fascinates me.

          Miguel Nicolelis: Brain-to-brain communication has arrived. How we did it

          https://www.ted.com/talks/miguel_nic..._how_we_did_it

          You may remember neuroscientist Miguel Nicolelis — he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What’s he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to "the limit of your imagination."
          I heard on Radio 4 this evening that he is hoping eventually to wire up stroke patients and physios.

            Intraspinal Microstimulation to Restore Hand Function
            http://www.movementlab.org/isms.html
            Instead of an exoskeleton why not use microstimulation of the spinal cord, the idea has been around longer.

              Effects of Lumbosacral Spinal Cord Epidural Stimulation for Standing after Chronic Complete Paralysis in Humans

              http://journals.plos.org/plosone/art...l.pone.0133998

              Abstract

              Sensory and motor complete spinal cord injury (SCI) has been considered functionally complete resulting in permanent paralysis with no recovery of voluntary movement, standing or walking. Previous findings demonstrated that lumbosacral spinal cord epidural stimulation can activate the spinal neural networks in one individual with motor complete, but sensory incomplete SCI, who achieved full body weight-bearing standing with independent knee extension, minimal self-assistance for balance and minimal external assistance for facilitating hip extension. In this study, we showed that two clinically sensory and motor complete participants were able to stand over-ground bearing full body-weight without any external assistance, using their hands to assist balance. The two clinically motor complete, but sensory incomplete participants also used minimal external assistance for hip extension. Standing with the least amount of assistance was achieved with individual-specific stimulation parameters, which promoted overall continuous EMG patterns in the lower limbs’ muscles. Stimulation parameters optimized for one individual resulted in poor standing and additional need of external assistance for hip and knee extension in the other participants. During sitting, little or negligible EMG activity of lower limb muscles was induced by epidural stimulation, showing that the weight-bearing related sensory information was needed to generate sufficient EMG patterns to effectively support full weight-bearing standing. In general, electrode configurations with cathodes selected in the caudal region of the array at relatively higher frequencies (25–60 Hz) resulted in the more effective EMG patterns for standing. These results show that human spinal circuitry can generate motor patterns effective for standing in the absence of functional supraspinal connections; however the appropriate selection of stimulation parameters is critical.

                    Robotic glove helps patients restore hand movements

                    http://www.sciencedaily.com/releases...0111092604.htm
                    Patients who have lost their hand functions due to injuries or nerve-related conditions, such as stroke and muscular dystrophy, now have a chance of restoring their hand movements by using a new lightweight and smart rehabilitation device called EsoGlove developed by a research team from the National University of Singapore (NUS).


                    Advanced Myoelectric Control for Robotic Hand-Assisted Training: Outcome from a Stroke Patient
                    http://journal.frontiersin.org/artic...017.00107/full

                    A hand exoskeleton driven by myoelectric pattern recognition was designed for stroke rehabilitation. It detects and recognizes the user’s motion intent based on electromyography (EMG) signals, and then helps the user to accomplish hand motions in real time. The hand exoskeleton can perform six kinds of motions, including the whole hand closing/opening, tripod pinch/opening, and the “gun” sign/opening. A 52-year-old woman, 8 months after stroke, made 20× 2-h visits over 10 weeks to participate in robot-assisted hand training. Though she was unable to move her fingers on her right hand before the training, EMG activities could be detected on her right forearm. In each visit, she took 4× 10-min robot-assisted training sessions, in which she repeated the aforementioned six motion patterns assisted by our intent-driven hand exoskeleton. After the training, her grip force increased from 1.5 to 2.7 kg, her pinch force increased from 1.5 to 2.5 kg, her score of Box and Block test increased from 3 to 7, her score of Fugl–Meyer (Part C) increased from 0 to 7, and her hand function increased from Stage 1 to Stage 2 in Chedoke–McMaster assessment. The results demonstrate the feasibility of robot-assisted training driven by myoelectric pattern recognition after stroke.

                      Something alike, interesting the world of soft micro actuators

                      Just thought for other uses; perhaps instead of a exoskeloton future ones might be wearable with small actuators woven in.

                        Brain Implant Gives Paralyzed Man Functional Control of Arm

                        http://neurosciencenews.com/paralysi...-control-4044/

                        Device allows paralyzed man to swipe credit card and perform other movements.

                        Six years ago, he was paralyzed in a diving accident. Today, he participates in clinical sessions during which he can grasp and swipe a credit card or play a guitar video game with his own fingers and hand. These complex functional movements are driven by his own thoughts and a prototype medical system that are detailed in a study published online today in the journal Nature.

                        The device, called NeuroLife, was invented at Battelle, which teamed with physicians and neuroscientists from The Ohio State University Wexner Medical Center to develop the research approach and perform the clinical study. Ohio State doctors identified the study participant and implanted a tiny computer chip into his brain.

                        That pioneering participant, Ian Burkhart, is a 24-year-old quadriplegic from Dublin, Ohio, and the first person to use this technology. This electronic neural bypass for spinal cord injuries reconnects the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb by using his thoughts. The device interprets thoughts and brain signals then bypasses his injured spinal cord and connects directly to a sleeve that stimulates the muscles that control his arm and hand.

                        “We’re showing for the first time that a quadriplegic patient is able to improve his level of motor function and hand movements,” said Dr. Ali Rezai, a co-author of the study and a neurosurgeon at Ohio State’s Wexner Medical Center.

                        Burkhart first demonstrated the neural bypass technology in June 2014, when he was able to open and close his hand simply by thinking about it. Now, he can perform more sophisticated movements with his hands and fingers such as picking up a spoon or picking up and holding a phone to his ear — things he couldn’t do before and which can significantly improve his quality of life.


                        Classifying three imaginary states of the same upper extremity using time-domain features
                        http://journals.plos.org/plosone/art...l.pone.0174161

                        Abstract

                        Brain-computer interface (BCI) allows collaboration between humans and machines. It translates the electrical activity of the brain to understandable commands to operate a machine or a device. In this study, we propose a method to improve the accuracy of a 3-class BCI using electroencephalographic (EEG) signals. This BCI discriminates rest against imaginary grasps and elbow movements of the same limb. This classification task is challenging because imaginary movements within the same limb have close spatial representations on the motor cortex area. The proposed method extracts time-domain features and classifies them using a support vector machine (SVM) with a radial basis kernel function (RBF). An average accuracy of 74.2% was obtained when using the proposed method on a dataset collected, prior to this study, from 12 healthy individuals. This accuracy was higher than that obtained when other widely used methods, such as common spatial patterns (CSP), filter bank CSP (FBCSP), and band power methods, were used on the same dataset. These results are encouraging and the proposed method could potentially be used in future applications including BCI-driven robotic devices, such as a portable exoskeleton for the arm, to assist individuals with impaired upper extremity functions in performing daily tasks.

                              The Importance of Visual Feedback Design in BCIs; from Embodiment to Motor Imagery Learning

                              http://journals.plos.org/plosone/art...l.pone.0161945

                              Abstract

                              Brain computer interfaces (BCIs) have been developed and implemented in many areas as a new communication channel between the human brain and external devices. Despite their rapid growth and broad popularity, the inaccurate performance and cost of user-training are yet the main issues that prevent their application out of the research and clinical environment. We previously introduced a BCI system for the control of a very humanlike android that could raise a sense of embodiment and agency in the operators only by imagining a movement (motor imagery) and watching the robot perform it. Also using the same setup, we further discovered that the positive bias of subjects’ performance both increased their sensation of embodiment and improved their motor imagery skills in a short period. In this work, we studied the shared mechanism between the experience of embodiment and motor imagery. We compared the trend of motor imagery learning when two groups of subjects BCI-operated different looking robots, a very humanlike android’s hands and a pair of metallic gripper. Although our experiments did not show a significant change of learning between the two groups immediately during one session, the android group revealed better motor imagery skills in the follow up session when both groups repeated the task using the non-humanlike gripper. This result shows that motor imagery skills learnt during the BCI-operation of humanlike hands are more robust to time and visual feedback changes. We discuss the role of embodiment and mirror neuron system in such outcome and propose the application of androids for efficient BCI training.
