The zSight 1920-100 is a variant of the zSight 1920 HMD. Both feature dual high-density 1920×1200 OLED displays and patented pristine optics that provide a crisp image – all the way to the image corners – as well as imperceptably low geometrical distortion.
The main difference between the zSight 1920 and the zSight 1920-100 is the overlap between the eyes. The zSight 1920 has 100% overlap, meaning that the field of view of each eye appears in the exact same direction. In this case, -30 to +30 degrees horizontally for 60 degree field of view. The zSight 1920-100 has partial overlap: the left eye still has 60 degree horizontal field of view but extends from -45 to +15 degrees. The right eye has 60 degree horizontal field of view but extends from -15 to +45 degree horizontally. Combined, the zSight 1920-100 provides a 90-degree horizontal field of view (-45 to +45 degrees) of which 30 degrees (-15 to +15) are common to both eyes. Check out illustrations of partial- and full-overlap at the bottom of this page.
The advantage of the zSight 1920-100 is that the overall field of view is wider: 90 degrees as opposed to 60 degrees. The advantage of the zSight 1920 is that, with full overlap between the eyes, if only a single video input is available, identical copies of it can be shown on both eyes and convergence will be achieved.
Both products support two additional video modes:
- Two separate inputs, where each eye receives a full-resolution image such as 1080p
- Side-by-side where a single input contains both left and right images, each image occupying half the overall width. The embedded electronics of the zSight split the image and display it properly on both eyes.
Both versions are available with options such as the low-latency wireless video link, eye tracking as well as augmented reality.
