It’s different than you might think. The Oculus Quest 2 is standalone, so you can play games right away without a PC, and it’s wireless, making it eas…
Yes, it’s for reference only now, but in the long term, it’s expected to enable preventative measures and even personalized health management.
Yes. Analyzing long-term patterns with AI and machine learning will enable more reliable predictions. As sensors become more precise, body fat and mus…
That’s right. These days, devices like Fitbit can track weight changes, heart rate, and activity patterns well, but they can’t measure muscle and fat …
Well, they’re not completely accurate. Most of the time, they’re based on indirect data. They analyze long-term trends by looking at things like activ…
Exactly. The AI analyzes my body composition, activity patterns, and health goals to provide personalized guidance, like, “Today, reduce cardio and fo…
There’s a significant difference. For example, the wearable receives real-time activity, heart rate, and calorie consumption data, and the nutrition a…
Yes. The internal components are coated with an anti-corrosion coating to make them resistant to salt and moisture. So, even if you use it for beach r…
That’s due to the chemical properties of the battery. These days, they use batteries with good low-temperature performance or incorporate battery mana…
Yes, basically, the first number is the dust protection rating, and the second is the water protection rating. For example, IP67 is completely dust-pr…
Yes, exactly. Combining an AR/VR headset with full-body tracking allows you to replicate the motions of picking up a sword and swinging it, or blockin…
That’s highly likely. If combined with AI, in-game characters could read facial expressions and gestures and react accordingly. For example, if you sm…
Yes, it’ll almost reach that level. Right now, it’s just my hands and arms, but in the future, if I wear a full-body suit, it’ll recognize everything …
Yes, that was the key. Thanks to technological miniaturization and design innovation, we can make devices as small as smart rings or compact Bluetooth…
These days, devices are capable of this thanks to IoT and 5G connectivity. For example, the Samsung Galaxy Watch can turn on lights and check the stat…
Yeah, these days, Apple Watches and Fitbit Senses can monitor everything from electrocardiograms to blood oxygen levels, skin temperature, and even st…
Yes, that’s a huge advantage. By securing early customers through platforms like Kickstarter or Indiegogo and sharing your product story on social med…
Of course! For example, Whoop provides detailed heart rate recovery data to professional athletes, and Oura Ring specializes in sleep and stress analy…
Yes, but the key is creating value that big companies can’t easily match. For example, targeting a specific niche market or being the first to introdu…
Exactly. By analyzing ECG or blood sugar data in chronological order, we can detect abnormal patterns and predict the likelihood of disease. We can al…
That’s right! RNNs can analyze time-series data like heart rate, movement, and oxygen saturation to distinguish between light sleep, deep sleep, and R…
Yes, simply looking at step counts doesn’t take advantage of RNNs’ strengths. RNNs are strong at understanding changes over time, so they can learn pa…
Exactly. While the exact algorithms for each product aren’t disclosed, the core idea is that statistical modeling and data analysis predict things lik…
That’s right. For example, the wearable blood pressure sensor developed by KAIST models the relationship between sensor voltage and actual blood press…
Well, not 100%. The basic principle is correct: it models the linear relationship between variables like exercise time, heart rate, and weight and cal…
Yes, that’s correct. For example, sleep trackers analyze past sleep data to predict future sleep stages or estimate daily activity levels based on act…
That’s correct. ARIMA is primarily used for preprocessing purposes like data stabilization, pattern analysis, and missing value correction, or combine…
To some extent, it’s possible. However, wearable data patterns vary from person to person, so it’s more useful for predicting short-term heart rate or…
Yes, it offers virtual fittings and skin condition analysis. It even offers styling tips and skincare advice, so it goes beyond simple health care and…
That’s right. The AI analyzes data like your weight, body fat, and heart rate to provide a cardiovascular health score and even recommend customized e…
