Summary
Audiences have been treated to several peaks behind the curtain atSonyfollowing recent patent publications, including a series of documents that reveal work on a biometric controller that would read chemical levels in players' hands.Sonyhas registered dozens of various patents and trademarks over the past several months, and this newest filing has once again peeled back the veil of the Japanese conglomerate’s research and development efforts.
Major technology companies like Sony have long invested in hardware and software improvements to increase the innovation andaccessibility of video games, with gaming controllers often a key focus. With many unique patented controller designs making their way to consumers over the years, players may be interested in learning more about the latest in-development Sony accessory.
According to a series of patents first filed in the United Kingdom in May 2022 and published in the United States in April 2025, Sony is working on a new controller that would be able to gauge biometric readings in players' hands and make in-game adjustments according to set protocols. This biometric system would utilize light sensors in the handles of a controller which would use emitted light data to identify compounds in the skin of the palm, such as cortisol, lactate, or glucose, and produce in-game modifications based on these readings. For example, high cortisol levels would indicate increased stress levels, so the biometric scan would trigger a lowered difficulty in single-player games and adjusted matchmaking in online multiplayer titles. Whether this biometric system could be added to existingSony PlayStation DualSense controllermodels is not specified, though the sample drawings do look similar to current-gen PS5 accessories.
Sony Biometric Controller Patent Details
As shown in Figures 3-4 of the Sony biometric controller patent, sensors along the handles of the device would use reflected light to determine the presence of certain chemicals in a player’s skin and use that data to determine if an in-game adjustment needs to be made. However, the patent further mentions utilizing this biometric system in other devices, such as a head-mounted display device, as shown in Figure 1, or even in a standalone handheld console. While the possibility of biometrics being introduced in a video game controller may be exciting, it is key to note that there is no guarantee that this controller design orother Sony gaming patentswill reach the production stage.
The publication of patents fornew video game technologiescan often indicate the goals of a company, such as Sony’s repeated filings' focus on user interactivity and immersion suggesting a heightened prioritization of the player experience. Audiences should always await official announcements before expecting to try out these new creations, so interested players will want to stay tuned for any updates on the biometric controller and other patented Sony designs.
