NeuroSky
NeuroSky, Inc. is a manufacturer of brain-computer interface (BCI) technologies for consumer product applications, which was founded in 2004 in Silicon Valley, California. The company adapts electroencephalography (EEG) and electromyography (EMG) technology to fit a consumer market within a number of fields such as entertainment (toys and games), education, automotive, and health. NeuroSky technology allows for low-cost EEG-linked research and products by using inexpensive dry sensors; older EEGs require the application of a conductive gel between the sensors and the head. The systems also include built-in electrical “noise” reduction software/hardware, and utilize embedded (chip level) solutions for signal processing and output. Neurosky primarily works as an original equipment manufacturer, or OEM, collaborating with industry partners, developers, and research institutions to deploy the technology into their own products and systems. When NeuroSky has released direct-to-con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electroencephalography
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the International 10-20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called "intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG analysis. Voltage fluctuations measured by the EEG bioamplifier and electrodes allow the evaluation of normal brain activity. As the electrical activity monitored by EEG originates in neurons in the underlying brain tissue, the recordings made by the electrodes on the surface of the scalp vary in accordance with their orienta ...

Neurowear
Neurowear is a gadget project organization in Japan founded on the concept of the "Augmented Human Body". The group's first project, known as Necomimi (from ) is a headband with a brain wave sensor and motorized cat shaped ears programmed to turn up or down based on the wearer's electroencephalogram (electrical potentials recorded at the scalp) influenced by "thoughts and emotions". neurowear collaborated with Qosmo and Daito Manabe on "unboxxx" exhibition in July 2012 at Gallery KATA Ebisu. Necomimi Necomimi is a headband with a MindWave brain wave sensor manufactured by NeuroSky and motorized cat shaped ears programmed to turn up when the wearer concentrates and to turn down when they relax. It runs for 4 hours on 4 AAA batteries and has interchangeable Cat, Dog, and Devil Horn ears. In November 2011, Time Magazine selected necomimi as one of the 50 best inventions of the year. Necomimi received an Honorary Mention in the Interactive Art category of 2013 Prix Ars El ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Trainer
The Force Trainer is a ''Star Wars''-themed toy which creates the illusion of performing Force-powered telekinesis. The brain–computer interface toy, released was Uncle Milton Industries' Star Wars Science line in 2009, comes with a headset that claims to sense the brain's electric fields (similar to an EEG) and relays the signals to a tube that uses a fan to blow a ball into the air. The harder the user concentrates, the harder the fan blows, and the higher the ball is suspended. The voice of Yoda instructs the user on developing their skills. In a 2010 episode of the College Humor series ''Bleep Bloop'', the hosts Jeff Rubin and Pat Cassels tested out the toy, even having a co-worker, Brian Murphy, play Brain Age ''Brain Age'', known as ''Dr Kawashima's Brain Training'' in PAL regions, is a series of video games developed and published by Nintendo, based on the work of Ryuta Kawashima.

Mindflex
Mindflex is a toy by Mattel by which a child uses their brain waves to steer a ball through an obstacle course. Brain waves are registered by the enclosed EEG headset, which allows the child to control an air stream by concentrating, thus lifting or lowering a foam ball. The game was released in the fall of 2009, and uses the same microchip as the MindSet from NeuroSky and homebuilt EEG machines. Controversy Despite the science behind the technology developed by Mattel, outside scientists have questioned whether the toy actually measures brain waves or just randomly moves the ball, exploiting the well-known illusion of control. (In German) However, despite the Spiegel/Haynes experiments, supporters of the game stand behind the research that went into the development of Mindflex, and believe that the headset does indeed read EEGs.

Archery
Archery is the sport, practice, or skill of using a bow to shoot arrows.Paterson ''Encyclopaedia of Archery'' p. 17 The word comes from the Latin ''arcus'', meaning bow. Historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity. A person who practices archery is typically called an archer, bowman, or toxophilite. History Origins and ancient archery The oldest known evidence of the bow and arrow comes from South African sites such as Sibudu Cave, where the remains of bone and stone arrowheads have been found dating approximately 72,000 to 60,000 years ago.Backwell L, d'Errico F, Wadley L.(2008). Middle Stone Age bone tools from the Howiesons Poort layers, Sibudu Cave, South Africa. Journal of Archaeological Science, 35:1566–1580.

Electrodes
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Anode and cathode in electrochemical cells Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell. This battery consisted of a stack of copper and zinc electrodes separated by brine-soaked paper disks. Due to fluctuation in the voltage provided by the voltaic cell it wasn't very practical. The first practical battery was invented in 1839 and named the Daniell cell after John Frederic Daniell. Still making use of the zinc–copper electrode combination. Since then many more batteries hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm can be expressed within a finite amount of spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurons
A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. The neuron is the main component of nervous tissue in all animals except sponges and placozoa. Non-animals like plants and fungi do not have nerve cells. Neurons are typically classified into three types based on their function. Sensory neurons respond to stimuli such as touch, sound, or light that affect the cells of the sensory organs, and they send signals to the spinal cord or brain. Motor neurons receive signals from the brain and spinal cord to control everything from muscle contractions to glandular output. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. When multiple neurons are connected together, they form what is called a neural circuit. A typical neuron consists of a cell body ( soma), dendrites, and a single axon. The soma is a compact structure, and the axon ...
