Newly discovered PS5 DualSense patent could solve drift issues for good

A Sony patent reveals that a new DualSense could include things like revamped analog sticks that utilize hydraulics for precision enter.

Equally the PS5 and the DualSense have experienced their reasonable share of concerns submit-launch. There&aposs at the moment a lawsuit underway, alleging the console introduced with a recognized defect. Meanwhile, the DualSense hasn&apost escaped drift issues with a US regulation company filing a course motion lawsuit around them final yr (through IGN). That seems to have fizzled out, with associated web pages removed from the corporation&aposs web-site. But controller drift challenges (and getting sued around them) could grow to be a factor of the past for Sony.

Metro noticed a patent filed by Sony for a controller with “a collapsible regulate stick employing a fluid”. The fluid in query is non-Newtonian – feel custard, ketchup, quicksand. Or in this context, anything that&aposs not a condiment, dessert, or mini deathtrap. It&aposs a fluid that modifications viscosity below pressure. So ketchup gets to be runnier when you shake, for illustration. Whereas you can fill a pool with custard and run throughout it without having sinking, correctly shown in this Brainiac: Science Abuse episode

The portion of the patent that dives into the history of the creation picks apart joytsticks, analog nubs, and thumbsticks. It breaks down the comfort and ease and portability of each and every, right before concluding:

“The thumbstick is much more snug for the user than the analog nub and is lesser than a joystick but is nonetheless not quite transportable. The protrusion of the thumbstick sticks up from the floor of the controller and can conveniently be caught [in] garments or other slim materials earning the thumbstick susceptible to breakage.

“It is in just this context that embodiments of the present invention come up.”

The diagram previously mentioned is of a retractable analog stick without having the existence of non-Newtonian fluid. In this instance, the shaft retracts into the thumbstick overall body, and both equally are “freely rotatable together all-around a pivot centre within the controller body.”

The image down below is the diagram depicting the inclusion of non-Newtonian fluids in the controller. The thumbstick shaft “incorporates a liquid interface floor” whole the entire body has a cavity crammed with the non-Newtonian fluid. 

If the person needs to retract the thumbstick, “slow force may perhaps be applied to the thumbstick shaft” to “displace the non-Newtonian fluid into the reservoir.” A quick, tough drive on the other hand will have the reverse influence.

“Thanks to the character of the non-Newtonian fluid, a brief application of stress to the thumbstick shaft will cause an increase in the viscosity of the non-Newtonian fluid and the fluid will not be displaced. 

“Therefore, throughout use the thumbstick shaft will not retract into the thumbstick body since the stress in the course of use is not utilized sluggish more than enough to displace the non-Newtonian fluid.”

But what does that suggest for the functional, day-to-day use of a new and improved PS5 DualSense?

With revamped analog sticks, the DualSense&aposs input controls could be considerably improved. The sticks are ordinarily utilised for movement and aiming, so those people could become a great deal additional nuanced. 

They may possibly also be utilized to shoehorn in added &aposinput buttons&apos specified the structure&aposs collapsible element. And they could present an enhanced array of movement and command in sports activities game titles, flight simulators, and the like. 

What that will suggest for recent game titles that use L3 and R3 inputs – specifically if it&aposs in a way that counters how these new analog sticks function in terms of velocity and power – we don&apost know. But we can&apost see Sony releasing a DualSense Professional that&aposs not compatible with the PS5&aposs existing catalog of titles. 

Of training course, the existence of a patent doesn&apost imply we&aposre going to see the idea occur to fruition in a bodily item. But it&aposs exciting to see what the minds at Sony are cooking up regardless.
