Sidewalk collisions involving pedestrians engrossed in their electronic devices have become an irritating (and sometimes dangerous) fact of city life. To prevent them, what about just creating a no cellphones lane on the sidewalk? Would people follow the signs? Thats what a TV crew decided to find out on a Washington, D.C., street Thursday, as part of a behavioral science experiment for a new National Geographic TV series. [via Quartz]
As expected, some pedestrians ignored the chalk markings designating a no-cellphones lane and a lane that warned pedestrians to walk at your own risk. Others didnt even see them because they were too busy staring at their phones. But others stopped, took pictures and posted themfrom their phones, of course.
MindRDR connects Google Glass with a device to monitor brain activity, allowing users to take pictures and socialise them on Twitter or Facebook.
Once a user has decided to share an image, we analyse their brain data and provide an evaluation of their ability to control the interface with their mind. This information is attached to every shared image.
The current version of MindRDR uses commercially available brain monitor Neurosky MindWave Mobile to extract core metrics from the mind.
Ekso is an exoskeleton bionic suit or a "wearable robot" designed to enable individuals with lower extremity paralysis to stand up and walk over ground with a weight bearing, four point reciprocal gait. Walking is achieved by the user’s forward lateral weight shift to initiate a step. Battery-powered motors drive the legs and replace neuromuscular function.

Experiential Virtual Scenarios With Real-Time Monitoring (Interreality) for the Management of Psychological Stress: A Block Randomized Controlled Trial
The recent convergence between technology and medicine is offering innovative methods and tools for behavioral health care. Among these, an emerging approach is the use of virtual reality (VR) within exposure-based protocols for anxiety disorders, and in particular posttraumatic stress disorder. However, no systematically tested VR protocols are available for the management of psychological stress. Objective: Our goal was to evaluate the efficacy of a new technological paradigm, Interreality, for the management and prevention of psychological stress. The main feature of Interreality is a twofold link between the virtual and the real world achieved through experiential virtual scenarios (fully controlled by the therapist, used to learn coping skills and improve self-efficacy) with real-time monitoring and support (identifying critical situations and assessing clinical change) using advanced technologies (virtual worlds, wearable biosensors, and smartphones).

Actually, according to my experience, citizens and public stakeholders are not well-informed or educated about mHealth. For example, to many people the idea of using phones to deliver mental health programs still sounds weird.
Yet the number of mental health apps is rapidly growing: a recent survey identified 200 unique mobile tools specifically associated with behavioral health.
These applications now cover a wide array of clinical areas including developmental disorders, cognitive disorders, substance-related disorders, as well as psychotic and mood disorders.
I think that the increasing "applification" of mental health is explained by three potential benefits of this approach:
- First, mobile apps can be integrated in different stages of treatment: from promoting awareness of disease, to increasing treatment compliance, to preventing relapse.
- Furthermore, mobile tools can be used to monitor behavioural and psychological symptoms in everyday life: self-reported data can be complemented with readings from inbuilt or wearable sensors to fine-tune treatment according to the individual patient’s needs.
- Last - but not least - mobile applications can help patients to stay on top of current research, facilitating access to evidence-based care. For example, in the EC-funded INTERSTRESS project, we investigated these potentials in the assessment and management of psychological stress, by developing different mobile applications (including the award-winning Positive Technology app) for helping people to monitor stress levels “on the go” and learn new relaxation skills.
In short, I believe that mental mHealth has the potential to provide the right care, at the right time, at the right place. However, from my personal experience I have identified three key challenges that must be faced in order to realize the potential of this approach.
I call them the three "nEEEds" of mental mHealth: evidence, engagement, enactment.
- Evidence refers to the need of clinical proof of efficacy or effectiveness to be provided using randomised trials.
- Engagement is related to the need of ensuring usability and accessibility for mobile interfaces: this goes beyond reducing use errors that may generate risks of psychological discomfort for the patient, to include the creation of a compelling and engaging user experience.
- Finally, enactment concerns the need that appropriate regulations enacted by competent authorities catch up with mHealth technology development.
Being myself a beneficiary of EC-funded grants, I can recognize that R&D investments on mHealth made by EC across FP6 and FP7 have contributed to position Europe at the forefront of this revolution. And the return of this investment could be strong: it has been predicted that full exploitation of mHealth solutions could lead to nearly 100 billion EUR savings in total annual EU healthcare spend in 2017.
I believe that a progressively larger portion of these savings may be generated by the adoption of mobile solutions in the mental health sector: actually, in the WHO European Region, mental ill health accounts for almost 20% of the burden of disease.
For this prediction to be fulfilled, however, many barriers must be overcome: thethree "nEEEds" of mental mHealth are probably only the start of the list. Hopefully, the Green Paper consultation will help to identify further opportunities and concerns that may be facing mental mHealth, in order to ensure a successful implementation of this approach.

Android Wear will show you info from the wide variety of Android apps, such as messages, social apps, chats, notifications, health and fitness, music playlists, and videos.
It will also enable Google Now functions — say “OK, Google” for flight times, sending a text, weather, view email, get directions, travel time, making a reservation, etc..
Google says it’s working with several other consumer-electronics manufacturers, including Asus, HTC, and Samsung; chip makers Broadcom, Imagination, Intel, Mediatek and Qualcomm; and fashion brands like the Fossil Group to offer watches powered by Android Wear later this year.
If you’re a developer, there’s a new section on developer.android.com/wear focused on wearables. Starting today, you can download a Developer Preview so you can tailor your existing app notifications for watches powered by Android Wear.
Glyph looks like a normal headset and operates like one, too. That is, until you move the headband down over your eyes and it becomes a fully-functional visual visor that displays movies, television shows, video games or any other media connected via the attached HDMI cable.
Using Virtual Retinal Display (VRD), a technology that mimics the way we see light, the Glyph projects images directly onto your retina using one million micromirrors in each eye piece. These micromirrors reflect the images back to the retina, producing a reportedly crisp and vivid quality.

People unfortunate enough to lose an arm or a leg often feel pain in their missing limb, an unexplained condition known as phantom limb pain. Researchers at Chalmers University of Technology in Sweden decided to test whether they can fool the brain into believing the limb is still there and maybe stop the pain.
They attached electrodes to the skin of the remaining arm of an amputee to read the myoelectric signals from the muscles below. Additionally, the arm was tracked in 3D using a marker so that the data could be integrated into a moving generated avatar as well as computer games. The amputee moves the arm of the avatar like he would if his own still existed, while the brain becomes reacquainted with its presence. After repeated use, and playing video games that were controlled using the same myoelectric interface, the person in the study had significant pain reduction after decades of phantom limb pain.
Here’s a video showing off the experimental setup:

Keio University scientists have developed a “neurocam” — a wearable camera system that detects emotions, based on an analysis of the user’s brainwaves.
The hardware is a combination of Neurosky’s Mind Wave Mobile and a customized brainwave sensor.
The users interests are quantified on a range of 0 to 100. The camera automatically records five-second clips of scenes when the interest value exceeds 60, with timestamp and location, and can be replayed later and shared socially on Facebook.
The researchers plan to make the device smaller, more comfortable, and fashionable to wear.

An improved assistive technology system for the blind that uses sonification (visualization using sounds) has been developed by Universidad Carlos III de Madrid (UC3M) researchers, with the goal of replacing costly, bulky current systems.
Called Assistive Technology for Autonomous Displacement (ATAD), the system includes a stereo vision processor measures the difference of images captured by two cameras that are placed slightly apart (for image depth data) and calculates the distance to each point in the scene.
Then it transmits the information to the user by means of a sound code that gives information regarding the position and distance to the different obstacles, using a small audio stereo amplifier and bone-conduction headphones.

Melody Shiue, an industrial design graduate from University of New South Wales, is proposing a wearable fetal ultrasound system to enhancing maternal-fetal bonding as a reassurance window. It is an e-textile based apparatus that uses 4D ultrasound. Latest stretchable display technology is also employed on the abdominal region, allowing other members of the family especially the father to connect with the foetus in its context. PreVue not only gives you the opportunity to interact and comprehend the physical growth of the baby, but also an early understanding of its personality as you see it yawning, rolling, smiling etc., bringing you closer till the day it finally rests into your arms.

A group of Polish engineers is working on a smart sleeping mask that they hope will allow people to get more out of their resting time, as well as allow for unusual sleeping schedules that would particularly benefit those who are often on-call. The NeuroOn mask will have an embedded EEG for brain wave monitoring, EMG for detecting muscle motion on the face, and sensors that can track whether your pupils are moving and whether they are going through REM. The team is currently raising money on Kickstarter where you can pre-order your own NeuroOn once it’s developed into a final product.

Abstract. Studying the brain in its natural state remains a major challenge for neuroscience. Solving this challenge would not only enable the refinement of cognitive theory, but also provide a better understanding of cognitive function in the type of complex and unpredictable situations that constitute daily life, and which are often disturbed in clinical populations. With mobile EEG, researchers now have access to a tool that can help address these issues. In this paper we present an overview of technical advancements in mobile EEG systems and associated analysis tools, and explore the benefits of this new technology. Using the example of motor imagery (MI) we will examine the translational potential of MI-based neurofeedback training for neurological rehabilitation and applied research.
