Here is a pair of smart glasses that puts a 140-inch screen at 4 meters in your view. The TCL NXTWEAR G has dual 1080p Sony FHD Micro OLED panels and 47 pixels-per-degree resolution. It weighs only 100g, so you can easily wear it around.
The TCL NXTWEAR G works with any smartphone, tablet, or laptop supporting USB Type-C. It has a bunch of sensors built-in (accelerometer, gyro, and compass).
