[Update] SDK 2.1.0 and Firmware 1.20.00 release

Publication　Sep. 4, 2023　｜　
Last Updated　Dec. 17, 2025

We now provide SDK (Spatial Reality Display Settings) ver. 2.1.0 and Firmware ver. 1.20.00 to improve and add product features.

*Applicable Models: ELF-SR2

With this update, the image quality and performance of the ELF-SR2 are not only more optimized, but also the usability of the ELF-SR2 in various situations is improved.

*To use the following functions, update both SDK and the firmware of ELF-SR2.

The following *1 and *2 image quality improvements need to be updated on the application as well. To maximize the functionality of this update, application developers should replace and rebuild the latest Unity and Unreal Engine Plugins. If the application is not supported, the *1 and *2 effects will not be reflected.

Overview of new and improved functions

For details, refer to the following: Spatial Reality Display Settings

New functions

1. Graphics Processing Setting *1	It is now possible to select "Picture Quality Priority" and "Performance Priority" for image processing. By selecting "Performance Priority" the load on the GPU is reduced, and content with a large amount of heavy data can be displayed smoothly.
2. Usage environment setting	The eye recognition algorithm can now be modified to suit your environment.
3. Viewer switching	Up to two viewers can now be configured to switch between eye recognition targets. The setting can also be assigned to the "Fn key".
4. Crosstalk Adjustment	This allows you to adjust the image quality to suit your audience with less crosstalk.

Improvements

5. Improved stability of eye detection	A motion prediction function has been added to pupil recognition. Improved detection processing has improved object display stability.
6. Improved stability of stereoscopic images in dark environments	Reduces screen flicker, which is particularly likely to occur in low light environments, resulting in more stable images.
7. Optimization of super-resolution processing *2	Super-resolution processing is optimized to enhance definition.
