Overwhelming image quality improvement and operability with organic EL have room for improvement.Try the smart glass "BT-300"

The BT-300 is the third generation of Epson's smart glass.The difference between generations is mainly the quality of the display.

To be honest, I was not very attracted to the BT-100 / BT-200.Because the image was dark and unclear, it was easier to use the outer light with a shade, and the goodness of the "see -through" was spoiled.The contrast was low and I felt blurred.

But in the BT-300, it improved dramatically.As a result of changing the device into an organic EL -based one, the brightness has been dramatically improved.The display unit is located in the left and right of the glasses, and has a structure that is led by the light mirror.As a result of becoming an organic EL base and no backlight, it was a big point in design.

By the way, how clearly, it became easier to see?

Unfortunately, it is difficult to understand the value unless you actually put the headset.Since it is displayed well only with "eyes with headsets", it is difficult to show the situation objectively in photos.

I tried my best, but it was only "somehow" I could understand.However, I think you can understand the high brightness.

So, it was "just an image", but I made a composite screen while looking into the video here.I have the impression of "strong light" a little more, but I want you to think it's really like this.

The big thing is that the brightness and transparency have been greatly improved.This time, I tried using it for most of the time without shade, but if the background was still dark, such as a desk, it looked without any problems.Of course, the darker could feel like the image floats in the dark, but above all, I felt attractive that it could be used in everyday space.

The display is 1,280 x 720 dots, the angle of view is about 23 degrees diagonal, not wide.Like HMD for VR, it is not a device that covers the entire view with a video.The so -called 360 -degree video can be seen, but it does not cover the whole view, so it lacks power and immersion.On the other hand, the resolution is quite high and the image quality is good, so there is no problem reading the web letters.I worked for a few hours while wearing it, but I thought it could be used practically.At the same price that can be obtained by individuals, there are no other see -through displays so far.

The problem, however, is that it is limited to "when the image is in the eyes properly".If the headset shifts even a little, the video becomes difficult to see.In short, the sweet spot is narrow.After knowing that, you need to put it on.The weight is still a problem, and the affinity with the glasses is also a problem.
