• EEG Headset and brainwave toys

    Neuroscientific breakthroughs have completely revolutionized the toy market, with decades of research leading to the development of a wide assortment of innovative brainwave toys. With unprecedented freedom and creativity leading the way, brainwave toys are changing the way we think about entertainment for the young and old alike. If you’re interested in brainwave toys, first you will have… Read More»

  • The temptation to design headsets without ground-reference ear clips (electrodes) is pervasive. This is predominantly because ear clips remain vestiges of clinical EEG systems that have made their way into consumer BCI products. Clamped lightly onto a person’s earlobe, ear clips have proven one of the most trusted ways to obtain reliable grounding and referencing… Read More»

  • As we have seen, there is a multitude of possible BCI form factors—each with advantages, disadvantages, and purposes. In the consumer market, the most popular form factor is the headset. OEMs choose headsets more often over other form factors because they lend themselves to more interesting and aesthetic expressions better tied to a particular brand… Read More»

  • BCI Devices - EEG Devices

    In our blog overviewing consumer EEG, we touched upon the concept that the use case dictates the complexity, cost and inconvenience of the optimal EEG system. Today, we will be looking at one important factor that affects all three of these areas when it comes to BCI devices: the number of EEG electrodes chosen to… Read More»

  • In our previous blog, we emphasized how BCI has been traditionally applied to control scenarios. We also pointed out that consumer BCI loses significant control granularity as a trade-off in order to meet consumer requirements for price, ease-of-use, aesthetic design and mobility. Its value proposition as a precise controller peripheral is weakened through this sacrifice… Read More»

  • In the EEG world, a Brain-Computer Interface is known as a BCI. Webster’s Dictionary defines an interface as a system through which one machine is connected to another machine. Unfortunately, this definition doesn’t explain how the data from the transmitting machine is being processed and utilized by the receiving machine. It also doesn’t elaborate on the… Read More»

  • Our world changes dramatically with each tick of the clock. Technology is constantly evolving and opening up new opportunities we never thought were possible. Take a classic example—the telephone. Not too long ago, many of us were stuck at home waiting next to our landlines for a service consultant to get back to us between… Read More»

  • Our earlier blog briefly introduced the topic of EEG artifacts. Basically, artifacts are noise sources that have overlaid onto the EEG and corrupted the purity of the brainwave signal when they are present. This is where noise filtering electronics, special materials and industrial design techniques are necessary to reduce noise influences. Two artifact types deserve… Read More»

  • Merriam-Webster defines an algorithm as a step-by-step procedure for solving a problem or accomplishing some end. Algorithms can be developed for any process—from how to make your morning coffee to something as odd as establishing a friendship (diagram). In the biosensor world, you will hear phrases like EEG algorithms. What are EEG algorithms and what… Read More»

  • EEG Headset and brainwave toys

    In our previous blog, we introduced the idea of EEG frequency bands, which can basically be described as a fixed range of wave frequencies and amplitudes over a time scale. These bands are components of the overall EEG waveform captured at an electrode. Scientists use mathematical models such as Fast Fourier Transforms to extract the… Read More»
