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»

Increasingly, consumers are demanding wearable devices that provide insight on their physical health through heart rate variability (HRV) tracking. That said, there are other benefits of tracking HRV for consumers, as it can not only be used to track physical health, but also emotional health. There are many benefits associated with tracking heart rate variability… Read More»

At-home health biometrics tracking is a growing market as consumers recognize the importance of empowering themselves when it comes to their personal health. For consumers to integrate health biometrics tracking into their day-to-day lives, it needs to be presented in a positive way. In this post, we’re going to explore the importance of positive experiences… Read More»

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»

Biofeedback therapy gives consumers the power to use their brain to better understand and control the inner workings of their body. Thanks to biofeedback, manufacturers have the opportunity to develop life-changing wearable and mobile devices for consumers from all walks of life. However, in order for device manufacturers to harness the power of biofeedback therapy,… 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»
