Caméra intelligente Sony prédit votre prochaine action sur le bouton

A new Sony patent details a potential strategy for reducing latency in future gaming hardware, utilizing an AI model enhanced by supplemental sensors.

Sony debuted its first official upscaler, PlayStation Spectral Super Resolution (PSSR), with the PlayStation 5 Pro. While PSSR effectively upscales lower resolutions to 4K, modern graphics techniques like frame generation often introduce added latency. This can result in smoother visuals but a less responsive gameplay feel.

GPU leaders AMD and Nvidia have addressed this with their respective Radeon Anti-Lag and Nvidia Reflex technologies. Now, evidence suggests Sony is developing its own proprietary solution.

Sony's rationale within the filing states: "Latency can occur between a user's input and the system's processing and execution of that command. This delay can lead to unintended consequences during gameplay."

The proposed solution involves multiple integrated components: a machine-learning AI model trained to anticipate the next input, coupled with an external sensor. One example describes a camera focused on the controller to detect which button a player is preparing to press. “In one example, the method may include using camera input for a machine learning (ML) model,” the patent explains. “The camera input can signal the impending user command.”

Another potential application involves using the controller buttons themselves as sensors. Given Sony's historical advocacy for analog buttons, this technology could be featured in a next-generation controller.

While the exact implementation described in the patent may not appear in a product like the PlayStation 6—such filings often evolve—it clearly indicates Sony's investment in technologies that reduce latency without compromising responsiveness. This is increasingly important with the adoption of frame-generating tech like FSR 3 and DLSS 3, which can add latency on any system.

Such a development would be particularly beneficial in fast-paced genres like twitch shooters, which demand both high frame rates and minimal input delay. However, whether this patent materializes in future hardware is yet to be seen.
